Pip*_*ine 13 android android-layout
我正在寻找如何在我的应用程序底部获得一个类似的栏,如Android的MyTubo(或GroupMe).像这样的东西:


谢谢你的回答.

另外对我来说,在Android中获取与iPhone的UITabBarController类似的东西的好方法包括使用RadioGroup和RadioButtons.这种方法的好处在于你也可以使用Fragment或任何你喜欢的东西,而不仅仅是Intent和Activity.
我写了一篇博文来实现Pied Piper的相同结果,但是使用了RadioGroup和RadioButtons.它是意大利语,但幸运的是,代码在国际上发表;)结果如下:

对于更精细的导航栏设计(就像原始问题中的那些),我认为这只是一个很酷和聪明的绘制问题;)

这是可能的TabActivity.
需要跟随事物......
TabHost与TabWidget在底部TabSpecTabActivity那个东道主Activities 和 ActivityGoups我做了一个微笑屏幕布局.

以下是步骤......
1.您需要TabWidget在TabHostres/layout/host.xml的底部添加
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#777777">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:id="@+id/layTab"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:background="@drawable/your_navigatio_tab_background_drawable"
android:layout_alignParentBottom="true"
android:layout_centerVertical="true"
>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
/>
</RelativeLayout>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_above="@id/layTab"/>
</RelativeLayout>
</TabHost>

2.接下来你需要selectors,每个人一个TabSpec,这是演示选择器:res/drawable/homeselector.xml
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="false" android:drawable="@drawable/home_image_when_not_selected"/>
<item android:state_selected="true" android:drawable="@drawable/home_selected" />
</selector>

3.此外,您还需要具有徽章或任何特殊布局效果的TabSpecs的布局,例如我的购物车TabSpec有徽章,所以我做了以下布局,调用:res/layout/cartbottom.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/cartselector"
android:gravity="right"
>
<Button
android:id="@+id/redbtn"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:text="00"
android:paddingBottom="3dp"
android:gravity="right|center_vertical"
android:paddingRight="9dp"
android:textSize="11dp"
android:textStyle="bold"
android:textColor="#ffffff"
android:background="@drawable/red_badge_drawable"
/>
</RelativeLayout>

最后是 TabActivity
package x.y;
import android.app.TabActivity;
import android.content.Intent;
import android.database.DatabaseUtils;
import android.database.sqlite.SQLiteDatabase;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TabHost;
import android.widget.Toast;
import android.widget.TabHost.TabSpec;
public class Host extends TabActivity {
public static Button btnRed; // Works as a badge
//Declared static; so it can be accessed from all other Activities
public static TabHost tabHost;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.host);
tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec homeTabSpec = tabHost.newTabSpec("tid1");
TabSpec signinTabSpec = tabHost.newTabSpec("tid2");
TabSpec cartTabSpec = tabHost.newTabSpec("tid3");
TabSpec moreTabSpec = tabHost.newTabSpec("tid4");
TabSpec searchTabSpec = tabHost.newTabSpec("tid5");
//Make Intents to your Activities or ActivityGroups
Intent intent1 = new Intent(this, Cart.class);
Intent intent2 = new Intent(this, Home.class);
Intent intent3 = new Intent(this, SignIn.class);
Intent intent4 = new Intent(this, Search.class);
Intent intent5 = new Intent(this, More.class);
LayoutInflater layoutInflater = this.getLayoutInflater();
View layout_with_badge = layoutInflater.inflate(R.layout.cartbottom, null);
btnRed = (Button) layout_with_badge.findViewById(R.id.redbtn);
String cnt = String.valueOf("0");// Number on the badge
btnRed.setBackgroundDrawable(getResources().getDrawable(R.drawable.red_badge_image_drawable));
btnRed.setText(cnt);
btnRed.setOnClickListener(new OnClickListener() {
//@Override
public void onClick(View v) {
tabHost.setCurrentTab(2);
}
});
cartTabSpec.setIndicator(layout_with_badge).setContent(intent1);
Drawable d = getResources().getDrawable(R.drawable.homeselector);
ImageView img1 = new ImageView(this);
img1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
img1.setImageDrawable(d);
homeTabSpec.setIndicator(img1).setContent(intent2);
d = getResources().getDrawable(R.drawable.signinselector);
img1 = new ImageView(this);
img1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
img1.setImageDrawable(d);
signinTabSpec.setIndicator(img1).setContent(intent3);
d = getResources().getDrawable(R.drawable.searchselector);
img1 = new ImageView(this);
img1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
img1.setImageDrawable(d);
searchTabSpec.setIndicator(img1).setContent(intent4);
d = getResources().getDrawable(R.drawable.moreselector);
img1 = new ImageView(this);
img1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
img1.setImageDrawable(d);
moreTabSpec.setIndicator(img1).setContent(intent5);
/* Add tabSpec to the TabHost to display. */
tabHost.addTab(homeTabSpec);
tabHost.addTab(signinTabSpec);
tabHost.addTab(cartTabSpec);
tabHost.addTab(searchTabSpec);
tabHost.addTab(moreTabSpec);
}
}

它看起来如何......

根据Android的规格,请不要这样做.这是iOS惯例,并不适用于Android平台.

不要使用底部标签栏
其他平台使用底部标签栏在应用程序的视图之间切换.根据平台惯例,Android的用于视图控制的选项卡显示在屏幕顶部的操作栏中.此外,Android应用可能会使用底栏来显示拆分操作栏上的操作.
您应遵循此指南,以便在Android平台上与其他应用程序建立一致的体验,并避免操作与Android视图切换之间的混淆.
