Android Tab 控件详解及实例
在桌面应用中Tab控件使用得非常普遍,那么我们经常在Android中也见到以Tab进行布局的客户端。那么Android中的Tab是如何使用的呢?
1.Activity
package com.wicresoft.activity; import com.wicresoft.myandroid.R; import android.app.TabActivity; import android.os.Bundle; import android.util.Log; import android.widget.TabHost; import android.widget.TabHost.OnTabChangeListener; @SuppressWarnings("deprecation") public class mainActivity extends TabActivity { private TabHost tabhost; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main_activity); //从TabActivity上面获取放置Tab的TabHost tabhost = getTabHost(); tabhost.addTab(tabhost //创建新标签one .newTabSpec("one") //设置标签标题 .setIndicator("红色") //设置该标签的布局内容 .setContent(R.id.widget_layout_red)); tabhost.addTab(tabhost .newTabSpec("two") .setIndicator("黄色") .setContent(R.id.widget_layout_yellow)); tabhost.addTab(tabhost .newTabSpec("three") .setIndicator("蓝色") .setContent(R.id.widget_layout_blue)); tabhost.setOnTabChangedListener(listener); } private OnTabChangeListener listener = new OnTabChangeListener(){ @Override public void onTabChanged(String arg0) { // TODO Auto-generated method stub Log.i("TabChange", arg0); } }; }
2.布局文件
<?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@android:id/tabhost"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TabWidget android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@android:id/tabs"> </TabWidget> <FrameLayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:id="@android:id/tabcontent"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/widget_layout_red" android:background="#ff0000" android:orientation="vertical"> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/widget_layout_yellow" android:background="#FCD209" android:orientation="vertical"> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/widget_layout_blue" android:background="#0000E3" android:orientation="vertical"> </LinearLayout> </FrameLayout> </LinearLayout> </TabHost>
3.Manifest文件
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.wicresoft.myandroid" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.wicresoft.activity.mainActivity" 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>
