在此页面 http://developer.android.com/tools/support-library/index.html

我知道了

v7 appcompat库的更改:已更新ActionBarDrawerToggle,其中包含菜单到箭头的动画

这是Google Play应用使用的内容吗？我在这句话中读得太多了吗？我需要更改才能获得此行为 - 我无法在API文档中找到它.

Answer 1

我在这里发布了一个示例应用程序,它使用新的工具栏类和ActionBarToggle来提供带有Play商店风格动画图标的ActionBar:

https://github.com/03lafaye/LollipopDrawerToggle

no-v7-support分支使用ActionBarToggle和框架Activity和Toolbar.主分支使用v7工具栏和ActionBarActivity.

不使用ActionBarActivity的设置如下所示:

package com.plafayette.lollipop;

import android.app.Activity;
import android.support.v4.widget.DrawerLayout;
import android.os.Bundle;
import android.support.v7.app.ActionBarDrawerToggle;
import android.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;

public class ToolbarActivity extends Activity {
    private ActionBarDrawerToggle toggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_toolbar);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setActionBar(toolbar);

        DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        toggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.open, R.string.close);
        toggle.setDrawerIndicatorEnabled(true);
        drawerLayout.setDrawerListener(toggle);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        toggle.syncState();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.toolbar, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (toggle.onOptionsItemSelected(item))
            return true;

        int id = item.getItemId();
        return id == R.id.action_settings || super.onOptionsItemSelected(item);
    }
}

请注意,您必须在主题中禁用窗口操作栏和标题栏,如下所示:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="android:Theme.Material.Light">
        <item name="android:windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
    </style>
</resources>

我想最新的v7 appcompat库的示例代码很快就会发布,这个帖子已经过时了.

来自Square的Chris Renke发布了up图标动画的备用后退.代码在GitHub上:https://github.com/ChrisRenke/DrawerArrowDrawable,他在http://chrisrenke.com/drawerarrowdrawable上写了一篇关于它的博客.

Answer 2

这很容易.

使用DrawerLayout的布局与以往一样.您使用android.support.v4.widget.DrawerLayout并创建抽屉和内容区域:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ff0"
    android:orientation="vertical" >
</RelativeLayout>

<ListView
    android:id="@+id/leftDrawer"
    android:layout_width="290dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#f0f"
    android:choiceMode="singleChoice"
    android:clickable="true"
    android:divider="@null"
    android:dividerHeight="0dp"
    android:scrollbars="none" />

主要更改在您的Java代码中.在您使用抽屉布局的Activity中,您必须从v7为ActionBarActivity扩展它.然后为DrawerLayout和ActionBarDrawerToggle创建变量.您的导入应如下所示:

import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.ActionBarActivity;

然后只需连接一切.请记住,新的抽屉布局没有图标!你不应该把它传递给你通常应该去的地方.我的活动代码:

import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.ActionBarActivity;
import android.view.MenuItem;

public class MainActivity extends ActionBarActivity {

    DrawerLayout drawerLayout;
    ActionBarDrawerToggle drawerToggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
        drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.app_name, R.string.app_name) {};

        drawerLayout.setDrawerListener(drawerToggle);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (drawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        drawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        drawerToggle.onConfigurationChanged(newConfig);
    }

}

它应该工作.

看看这里

MainActivity.java:

package com.poliveira.apps.materialtests;

import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.widget.Toast;


public class MainActivity extends ActionBarActivity implements NavigationDrawerCallbacks {

    private Toolbar mToolbar;
    private NavigationDrawerFragment mNavigationDrawerFragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowHomeEnabled(true);

        mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager().findFragmentById(R.id.fragment_drawer);
        mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public void onNavigationDrawerItemSelected(int position) {
        Toast.makeText(this, "Menu item selected -> " + position, Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onBackPressed() {
        if (mNavigationDrawerFragment.isDrawerOpen())
            mNavigationDrawerFragment.closeDrawer();
        else
            super.onBackPressed();
    }
}

activity_main.xml中:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include
        android:id="@+id/toolbar_actionbar"
        layout="@layout/toolbar_default"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/toolbar_actionbar">

        <FrameLayout
            android:id="@+id/container"
            android:layout_width="match_parent"
            android:clickable="true"
            android:layout_height="match_parent"/>

        <!-- android:layout_marginTop="?android:attr/actionBarSize"-->
        <fragment
            android:id="@+id/fragment_drawer"
            android:name="com.poliveira.apps.materialtests.NavigationDrawerFragment"
            android:layout_width="@dimen/navigation_drawer_width"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            app:layout="@layout/fragment_navigation_drawer"/>
    </android.support.v4.widget.DrawerLayout>
</RelativeLayout>

Answer 4

你似乎有一个工作抽屉,如果没有,"创建导航抽屉"的文档非常好.

更新了ActionBarDrawerToggle,其中包含菜单到箭头的动画

以上引用是指使用箭头和汉堡包菜单提交创建一个新的ActionBarDrawerToggle.作为一个相关的一个:setDrawerIndicatorEnabled在加入新ArrowDrawer禁用抽屉指标添加能力.

因此请确保setDrawerIndicatorEnabled不要使用false和调用

import android.support.v7.app.ActionBarDrawerToggle;

代替

import android.support.v4.app.ActionBarDrawerToggle;

无论如何,从弃用警告中应该非常明显:

@deprecated请在support-v7-appcompat中使用ActionBarDrawerToggle.

可能也需要

// <item name="displayOptions">showHome|homeAsUp</item>
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);

Answer 5

首先,请确保您更新到最新的SDK.在buid.gradle如gradle这个依赖Android Studio中创建新项目,然后添加程序兼容性-v7.21.0 +和程序兼容性-v4.21.0 +库.

compile 'com.android.support:appcompat-v7:21.0.2'
compile 'com.android.support:support-v4:21.0.2'

在color.xml文件中添加primaryColor和primarycolorDark.

<resources>
<color name="primaryColor">#2196F3</color>
<color name="primaryColorDark">#0D47A1</color>
</resources>

在strings.xml文件中添加抽屉打开/关闭字符串值.

<resources>
<string name="app_name">Lollipop Drawer</string>
<string name="action_settings">Settings</string>
<string name="drawer_open">open</string>
<string name="drawer_close">close</string>
</resources>

您的activity_my.xml布局文件如下所示:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">

<include layout="@layout/toolbar" />


<android.support.v4.widget.DrawerLayout
    android:layout_width="match_parent"
    android:id="@+id/drawerLayout"
    android:layout_height="match_parent">

    <!-- activity view -->
    <RelativeLayout
        android:layout_width="match_parent"
        android:background="#fff"
        android:layout_height="match_parent">

        <TextView
            android:layout_centerInParent="true"
            android:layout_width="wrap_content"
            android:textColor="#000"
            android:text="Activity Content"
            android:layout_height="wrap_content" />
    </RelativeLayout>

    <!-- navigation drawer -->
    <RelativeLayout
        android:layout_gravity="left|start"
        android:layout_width="match_parent"
        android:background="#fff"
        android:layout_height="match_parent">

        <ListView
            android:id="@+id/left_drawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:divider="#eee"
            android:background="#fff"
            android:dividerHeight="1dp" />
    </RelativeLayout>

</android.support.v4.widget.DrawerLayout>

</LinearLayout>

您的toolbar.xml布局文件如下所示:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:layout_width="match_parent"
android:layout_height="wrap_content">

</android.support.v7.widget.Toolbar>

您的MyActivity.java如下所示:此处您的活动必须扩展ActionBarActivity并将工具栏设置为支持操作栏.

import android.content.res.Configuration;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MyActivity extends ActionBarActivity {

private Toolbar toolbar;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
private ListView leftDrawerList;
private ArrayAdapter<String> navigationDrawerAdapter;
private String[] leftSliderData = {"Home", "Android", "Sitemap", "About", "Contact Me"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    nitView();
    if (toolbar != null) {
        toolbar.setTitle("Navigation Drawer");
        setSupportActionBar(toolbar);
    }
    initDrawer();
}

private void nitView() {
    leftDrawerList = (ListView) findViewById(R.id.left_drawer);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    navigationDrawerAdapter=new ArrayAdapter<String>( MyActivity.this, android.R.layout.simple_list_item_1, leftSliderData);
    leftDrawerList.setAdapter(navigationDrawerAdapter);
}

private void initDrawer() {

    drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);

        }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);

        }
    };
    drawerLayout.setDrawerListener(drawerToggle);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    drawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    drawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.my, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    if (drawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

在android-lollipop的values-21文件夹中创建style.xml文件

<?xml version="1.0" encoding="utf-8"?>
<resources>

<style name="myAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryColorDark</item>
    <item name="android:statusBarColor">@color/primaryColorDark</item>

    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/black</item>
</style>

</resources>

在旧版本的值文件夹中创建style.xml文件,然后在android lollipop中创建

<resources>

<style name="myAppTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryColorDark</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/black</item>
</style>

</resources>

您的AndroidManifest.xml如下所示:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="nkdroid.com.lollipopdrawer" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/myAppTheme" >
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>
