谷歌是如何做到这一点的？在Android应用程序中滑动ActionBar

Question

我真的想在我自己的应用程序中实现这个(侧面导航),有谁知道Google如何设法做到这一点？

他们似乎已将当前窗口拉到一边并进入他们自己的飞入导航.

Answer 1

事实上,有一种方法可以做到这一点.即使没有实施自己的ActionBar.

看看hierachyviewer吧!(位于工具目录中)

还有的DecorView,并且LinearLayout作为一个孩子.这LinearLayout包含ActionBar其他内容和其他内容.所以,你可以简单地应用一些FrameLayout.LayoutParams,LinearLayout并以这种方式在左侧获得一些空间.然后,您可以使用菜单ListView填充此空间,并使用FrameLayout覆盖其他内容,当单击它时,折叠菜单.所以,这里有一些代码:

首先,折叠/扩展类(SlideMenu.java):

package your.cool.app;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Rect;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.Window;
import android.view.animation.TranslateAnimation;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;

public class SlideMenu {
//just a simple adapter
public static class SlideMenuAdapter extends ArrayAdapter<SlideMenu.SlideMenuAdapter.MenuDesc> {
    Activity act;
    SlideMenu.SlideMenuAdapter.MenuDesc[] items;
    class MenuItem {
        public TextView label;
        public ImageView icon;
    }
    static class MenuDesc {
        public int icon;
        public String label;
    }
    public SlideMenuAdapter(Activity act, SlideMenu.SlideMenuAdapter.MenuDesc[] items) {
        super(act, R.id.menu_label, items);
        this.act = act;
        this.items = items;
        }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        if (rowView == null) {
            LayoutInflater inflater = act.getLayoutInflater();
            rowView = inflater.inflate(R.layout.menu_listitem, null);
            MenuItem viewHolder = new MenuItem();
            viewHolder.label = (TextView) rowView.findViewById(R.id.menu_label);
            viewHolder.icon = (ImageView) rowView.findViewById(R.id.menu_icon);
            rowView.setTag(viewHolder);
        }

        MenuItem holder = (MenuItem) rowView.getTag();
        String s = items[position].label;
        holder.label.setText(s);
        holder.icon.setImageResource(items[position].icon);

        return rowView;
    }
}

private static boolean menuShown = false;
private static View menu;
private static LinearLayout content;
private static FrameLayout parent;
private static int menuSize;
private static int statusHeight = 0;
private Activity act;
SlideMenu(Activity act) {
    this.act = act;
}
//call this in your onCreate() for screen rotation
public void checkEnabled() {
    if(menuShown)
        this.show(false);
}
public void show() {
//get the height of the status bar
    if(statusHeight == 0) {
        Rect rectgle = new Rect();
        Window window = act.getWindow();
        window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
        statusHeight = rectgle.top;
        }
    this.show(true);
}
public void show(boolean animate) {
    menuSize = Functions.dpToPx(250, act);
    content = ((LinearLayout) act.findViewById(android.R.id.content).getParent());
    FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
    parm.setMargins(menuSize, 0, -menuSize, 0);
    content.setLayoutParams(parm);
//animation for smooth slide-out
    TranslateAnimation ta = new TranslateAnimation(-menuSize, 0, 0, 0);
    ta.setDuration(500);
    if(animate)
        content.startAnimation(ta);
    parent = (FrameLayout) content.getParent();
    LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    menu = inflater.inflate(R.layout.menu, null);
    FrameLayout.LayoutParams lays = new FrameLayout.LayoutParams(-1, -1, 3);
    lays.setMargins(0,statusHeight, 0, 0);
    menu.setLayoutParams(lays);
    parent.addView(menu);
    ListView list = (ListView) act.findViewById(R.id.menu_listview);
    list.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //handle your menu-click
        }
    });
    if(animate)
        menu.startAnimation(ta);
    menu.findViewById(R.id.overlay).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            SlideMenu.this.hide();
        }
    });
    Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), false);
    ((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(false);
    ((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(false);
    menuShown = true;
    this.fill();
}
public void fill() {
    ListView list = (ListView) act.findViewById(R.id.menu_listview);
    SlideMenuAdapter.MenuDesc[] items = new SlideMenuAdapter.MenuDesc[5];
    //fill the menu-items here
    SlideMenuAdapter adap = new SlideMenuAdapter(act, items);
    list.setAdapter(adap);
}
public void hide() {
    TranslateAnimation ta = new TranslateAnimation(0, -menuSize, 0, 0);
    ta.setDuration(500);
    menu.startAnimation(ta);
    parent.removeView(menu);

    TranslateAnimation tra = new TranslateAnimation(menuSize, 0, 0, 0);
    tra.setDuration(500);
    content.startAnimation(tra);
    FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
    parm.setMargins(0, 0, 0, 0);
    content.setLayoutParams(parm);
    Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), true);
    ((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(true);
    ((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(true);
    menuShown = false;
}
}

一些帮助方法(对我来说,在静态Functions.java中):

    public static int dpToPx(int dp, Context ctx) {
    Resources r = ctx.getResources();
    return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics());
}
//originally: http://stackoverflow.com/questions/5418510/disable-the-touch-events-for-all-the-views
//modified for the needs here
public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
    int childCount = viewGroup.getChildCount();
    for (int i = 0; i < childCount; i++) {
        View view = viewGroup.getChildAt(i);
        if(view.isFocusable())
            view.setEnabled(enabled);
        if (view instanceof ViewGroup) {
            enableDisableViewGroup((ViewGroup) view, enabled);
            } else if (view instanceof ListView) {
                if(view.isFocusable())
                    view.setEnabled(enabled);
                ListView listView = (ListView) view;
                int listChildCount = listView.getChildCount();
                for (int j = 0; j < listChildCount; j++) {
                    if(view.isFocusable())
                        listView.getChildAt(j).setEnabled(false);
                    }
                }
        }
    }

然后,布局:

菜单布局(res/layout/menu.xml)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent" >
    <LinearLayout
        android:orientation="vertical"
        android:layout_height="fill_parent"
        android:layout_width="250dip"
        android:background="@color/darkblack">
        <ListView
            android:id="@+id/menu_listview"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:divider="@color/dividerblack"
            android:dividerHeight="2dip"  />
    </LinearLayout>
    <FrameLayout
        android:id="@+id/overlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>
</LinearLayout>

listitems的布局(res/layout/menu_listitem.xml):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
    <ImageView
        android:id="@+id/menu_icon"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_marginRight="5dip"
        android:layout_marginLeft="10dip"
        android:layout_marginTop="10dip"
        android:layout_marginBottom="10dip" />

    <TextView
        android:id="@+id/menu_label"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="@color/white"
        android:textSize="24dp"
        android:layout_marginTop="10dip"
        android:layout_marginBottom="10dip" />
</LinearLayout>

如何使用它:

在你的onCreate():

private SlideMenu slidemenu;
@Override
public void onCreate(Bundle savedInstanceState) {
    //your onCreate code
    slidemenu = new SlideMenu(this);
    slidemenu.checkEnabled();
}

在ActionBar homebutton的处理程序中:

slidemenu.show();

而已!

现在,它的一些屏幕截图:

据我所知,它正在发挥作用.如果您遇到任何问题或我的解释不明确,请与我联系!

编辑:ExtendedViewPager&ExtendedPagerStrip:

ExtendedViewPager:

package your.cool.app;

//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class ExtendedViewPager extends ViewPager {

private boolean enabled;

public ExtendedViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
}
}

ExtendedPagerTabStrip:

package your.cool.app;

//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html

import android.content.Context;
import android.support.v4.view.PagerTabStrip;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class ExtendedPagerTabStrip extends PagerTabStrip {

private boolean enabled;

public ExtendedPagerTabStrip(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setNavEnabled(boolean enabled) {
    this.enabled = enabled;
}
}

我将它SlideMenu用于一个ViewPager带有PagerTabStripfor,如Talk,Market等标签的Activity .你不能以一种简单的方式禁用这些视图,所以上面的两个类只是扩展它们以onTouch在禁用时停止事件.

Answer 2

有几次尝试这样做,但是我还没有找到关于如何使用所有API级别的动作栏成功实现它的lib或源代码.一个有希望的lib就在这里

https://github.com/jfeinstein10/SlidingMenu

这是一个示例应用程序的视频.

这是Google Play应用链接.

这适用于ActionbarSherlock.您将不得不使用ABS构建SlidingMenu库以使其正常工作.工作,看起来很棒!

Answer 3

做了原始实现的总结并添加了XML解析以及autodetection可能存在的解析actionbar,因此它适用于本机以及支持操作栏,例如ActionBarSherlock.

整个事情现在是一个图书馆项目和一个示例应用程序,并在滑动菜单上为Android描述感谢scirocco最初的想法和代码!

Answer 4

如果您使用的API级别大于11,则可以使用受@Scirocco给出的答案启发的更简单的方法

// get content parent that is basically the whole 
// app screen (viewed from hierarchy viewer)
final LinearLayout content = 
     (LinearLayout) findViewById(android.R.id.content).getParent();

// make new value animator with range from 0 to 1
final ValueAnimator animator = ValueAnimator.ofFloat(0, 1);
// set custom duration
animator.setDuration(500);
// on update is called for every value in the 
    // given range in time frame defined by the duration
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

    public void onAnimationUpdate(ValueAnimator animation) {
        // get the current value
        float value = ((Float) (animation.getAnimatedValue())).floatValue();
        // translate by that value, minus means translate left
        content.setTranslationX(-250 * value);
    }
});
// start the animator
animator.start();

// make or inflate custom view for test purposes 
Button textView = new Button(this);
textView.setText("TestButton");
// add it to the frame layout that is the parent of the content on position 0
FrameLayout parent = (FrameLayout) content.getParent();
parent.addView(textView, 0);

这里的想法是使用ValueAnimator该变换,而不仅仅使用操作栏为主要布局设置动画,因此您可以与要用作滑动面板的膨胀视图进行交互.您应该将硬编码值替换为您的应用程序使用的内容.

我希望这有帮助 :)

Answer 5

好吧,目前我正在研究一个项目,并且遇到了滑动菜单,我用谷歌搜索,但是看到没有人给出一些代码或者如何开始制作滑动菜单的一些提示而感到非常失望,但每个人都给了一些链接github的项目/库使用,我决定自己做,最后我有自己的Sliding Menu Ready ...

我已经花了两天时间

1.制作滑动动画

2.使其适用于所有屏幕分辨率

一旦你对动画有了一些了解,它真的很容易和简单,我已经阅读了一些地方,重新发明轮子是不明智的(那些人正在引用滑动菜单的github源代码),但我认为你应该至少一次尝试制作自己的,以便了解它的实际工作原理和功能:P

所以这是我的滑动菜单将如何工作的图片

在find.xml中,我最初包含了filter.xml,它是不可见的

    }

    @Override
    public void onAnimationEnd(Animation animation) 
    {
        if(isOtherSlideOut) //Now here we will actually move our view to the new position,because animations just move the pixels not the view

            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(otherLayoutWidth, otherLayoutHeight);

            params.leftMargin = margin;

            params.rightMargin = -margin; //same margin from right side (negavite) so that our layout won't get shrink

            otherLayout.setLayoutParams(params);

            isOtherSlideOut = true;

            dimOtherLayout();
        }
    }

    @Override
    public void onAnimationRepeat(Animation animation) 
    {

    }

    @Override
    public void onAnimationStart(Animation animation) 
    {

    }

    private void dimOtherLayout()

        AlphaAnimation alphaAnimation = new AlphaAnimation(1.0f, 0.5f);

        alphaAnimation.setFillAfter(true);

        otherLayout.startAnimation(alphaAnimation);
    }

}

        filterAnimation = new FilterAnimation(this);

        initializeAnimations(); 
    }

    private void initializeAnimations()
    {   //Setting GlobolLayoutListener,when layout is completely set this function will get called and we can have our layout onbject with correct width & height,else if you simply try to get width/height of your layout in onCreate it will return 0

        final ViewTreeObserver filterObserver = filterLayout.getViewTreeObserver();

        filterObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() 
        {

            @Override

                DisplayMetrics displayMetrics = getResources().getDisplayMetrics();

                int deviceWidth = displayMetrics.widthPixels;

                int filterLayoutWidth = (deviceWidth * 80) / 100; //here im coverting device percentage width into pixels, in my other_slide_in.xml or other_slide_out.xml you can see that i have set the android:toXDelta="80%",so it means the layout will move to 80% of the device screen,to work across all screens i have converted percentage width into pixels and then used it

                RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(filterLayoutWidth, RelativeLayout.LayoutParams.MATCH_PARENT);

                filterLayout.setLayoutParams(params);//here im setting the layout params for my filter.xml because its has width 260 dp,so work it across all screen i first make layout adjustments so that it work across all screens resolution 

                filterAnimation.initializeFilterAnimations(filterLayout);

            }
        });

        final ViewTreeObserver findObserver = findLayout.getViewTreeObserver();

        findObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() 
        {

            @Override
            public void onGlobalLayout() 
            {
                findLayout.getViewTreeObserver().removeGlobalOnLayoutListener(this);

                filterAnimation.initializeOtherAnimations(findLayout);
            }
        });

    }

    @Override
    public void onClick(View v) 
    {
        int id = v.getId();

        switch(id)
        {

        case R.id.filter:

            filterAnimation.toggleSliding();

            break;
        }
    } 

}

在那里你可以找到一个完整的工作和功能滑动菜单,你可以自定义它以满足你的要求,如果任何人仍然有一些问题设置,随时问,我很乐意帮助你:)

Answer 6

我创建了自己的解决方案,用于滑动视图并在下面显示菜单,因为许多其他解决方案似乎无法在较旧的Android版本上运行或缺乏有关如何使其工作的正确说明.

我的解决方案具有以下功能:

• 提供对滑动视图以显示位于其下方的菜单的支持
• 菜单和上面的视图都可以是任何自定义视图
• 支持旧的Android版本(经测试至少在Android 2.2上运行)
• 适用于PhoneGap/Cordova项目

该解决方案使用名为SlidingMenuLayout的自定义布局,您需要添加2个视图.您添加的第一个视图是菜单,第二个是主视图.

将布局添加到现有项目的最简单方法是覆盖Activity的setContentView()方法:

@Override
public void setContentView(View view) {
    SlidingMenuLayout layout = new SlidingMenuLayout(this);
    layout.setLayoutParams(new LinearLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT,
        ViewGroup.LayoutParams.MATCH_PARENT, 
        0.0F));
    layout.addView(new MenuView(this));
    layout.addView(view);
    super.setContentView(layout);
}

在此示例中,MenuView是实际显示菜单的视图.由您来实现此视图.
最后,您可以根据需要添加一个按钮(通常位于主视图的左上角),调用openMenu()或closeMenu()布局.
代码可以SlidingMenuLayout在GitHub 项目页面上找到.
