先說布局文件,如下:利用Android:layout_alignParentBottom="true" 實現底部顯示
- <?xml version="1.0" encoding="utf-8"?>
- <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
- android:id="@android:id/tabhost"
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <RelativeLayout
- android:background="@drawable/g"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <TabWidget android:id="@android:id/tabs"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:layout_alignParentBottom="true">
- </TabWidget>
- <FrameLayout android:id="@android:id/tabcontent"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <RelativeLayout android:id="@+id/tabFirst"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- android:orientation="vertical">
- <AnalogClock
- android:id="@+id/widget31"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerInParent="true">
- </AnalogClock>
- </RelativeLayout>>
- <RelativeLayout android:id="@+id/tabSecond"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- android:orientation="vertical">
- <DigitalClock
- android:layout_centerInParent="true"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content">
- </DigitalClock>
- </RelativeLayout>
- </FrameLayout>
- </RelativeLayout>
- </TabHost>
下面是主程序代碼,注釋寫的比較詳細,這裡就不在多解釋了
- package com.cloay;
-
- import android.app.TabActivity;
- import android.graphics.Color;
- import android.os.Bundle;
- import android.widget.TabHost;
- import android.widget.TabHost.OnTabChangeListener;
- import android.widget.Toast;
-
- public class TabTestActivity extends TabActivity {
- TabHost tabHost;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- //獲取TabHost對象
- tabHost = getTabHost();
- // tabHost.setup();
- //新建一個newTabSpec,設置標簽和圖標(setIndicator),設置內容(setContent)
- tabHost.addTab(tabHost.newTabSpec("Test one").setIndicator("",getResources().getDrawable(android.R.drawable.ic_menu_call)).setContent(R.id.tabFirst));
- tabHost.addTab(tabHost.newTabSpec("Test two").setIndicator("",getResources().getDrawable(android.R.drawable.ic_menu_camera)).setContent(R.id.tabSecond));
- //設置TabHost的背景顏色
- tabHost.setBackgroundColor(Color.argb(150,22,70,150));
- //設置TabHost的背景圖片資源
- // tabHost.setBackgroundResource(R.drawable.bg);
- //設置當前現實哪一個標簽
- tabHost.setCurrentTab(0); //0為標簽ID
- //標簽切換處理,用setOnTabChangedListener
- tabHost.setOnTabChangedListener(new OnTabChangeListener(){
- public void onTabChanged(String tabId){
- Toast.makeText(TabTestActivity.this, "This is a Test!", Toast.LENGTH_LONG).show();
- }
- });
- }
- }
