Tabhost嵌套以及Tab中多个Activity跳转的实现今天明白了Tabhost嵌套和Tab里实现多个Activity的跳转原理，自己做了一个demo，先看看效果图：源码如下： [java] view plaincopy （1） DoubleTabHost package yy.android.tab; import android.app.TabActivity; import android.co 阅读详情

如图，我想在点击"all songs"之后跳转到一个播放列表，但是不知道这儿怎么用TabHost才能在播放列表上也显示？

我的TabHost所在的Activity的代码如下



/*package com.lxy.musicplayer.view;



import com.lxy.musicplayer.R;



import android.app.TabActivity;

import android.content.Intent;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.Window;

import android.widget.TabHost;



public class BuddleTabHostActivity extends TabActivity {

	

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);



		

		TabHost tab  = getTabHost();

//		LayoutInflater.from(this).inflate(R.layout.tabhost_layout, tab.getTabContentView(),true);

		

		super.onCreate(savedInstanceState);

	    requestWindowFeature(Window.FEATURE_NO_TITLE);

		setContentView(R.layout.tabhost_layout);

		

		

		addIntentActivity(tab, MainActivity.class, "所有歌曲");

		addIntentActivity(tab, MainActivity.class, "网络歌曲");

		addIntentActivity(tab, MainActivity.class, "我的设置");

		

		tab.setCurrentTab(0);

		



	}

	

	

	private void addIntentActivity(TabHost tab,Class c,String title){

		Intent intent = new Intent();

		intent.setClass(this, c);

		

		TabHost.TabSpec spec = tab.newTabSpec(title);

		spec.setIndicator(title);

		spec.setContent(intent);

		tab.addTab(spec);

		

	}

	



}

*/



package com.lxy.musicplayer.view;



import com.lxy.musicplayer.R;



import android.app.TabActivity;

import android.content.Intent;

import android.content.res.Resources;

import android.os.Bundle;

import android.view.Window;

import android.widget.TabHost;



public class BuddleTabHostActivity extends TabActivity{

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

	    requestWindowFeature(Window.FEATURE_NO_TITLE);

		setContentView(R.layout.tabhost_layout);

		//获得切换对象

		TabHost tab=getTabHost();

		addIntentActivity(tab, MainActivity.class,"local");

		addIntentActivity(tab, PlayActivity.class,"favorite");

		addIntentActivity(tab, PlayListActivity.class,"online");

		addIntentActivity(tab, MainActivity.class,"setting");

		//默认执行选项卡

		tab.setCurrentTab(0);

	}

	

	public void addIntentActivity(TabHost tab,Class<?> c,String str){

		Intent intent=new Intent();

		intent.setClass(this, c);

		//由切换对象获得选项卡

		TabHost.TabSpec spec=tab.newTabSpec(str);

		//设置选项卡信息

		//跳转要显示的页面

		spec.setIndicator(str);

		spec.setContent(intent);

		//添加选项卡

		tab.addTab(spec);

	}

照以下的代码做，就能解决你的问题： ActivityStack.java

private Stack<String> stack;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (stack == null)
        stack = new Stack<String>();
    // start default activity
    push("FirstStackActivity", new Intent(this, Tab_SampleActivity.class));
}

@Override
public void finishFromChild(Activity child) {
    pop();
}

@Override
public void onBackPressed() {
    pop();
}

public void push(String id, Intent intent) {
    Window window = getLocalActivityManager().startActivity(id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
    if (window != null) {
        stack.push(id);
        setContentView(window.getDecorView());
    }
}

public void pop() {
    if (stack.size() == 1)
        finish();
    LocalActivityManager manager = getLocalActivityManager();
    manager.destroyActivity(stack.pop(), true);
    if (stack.size() > 0) {
        Intent lastIntent = manager.getActivity(stack.peek()).getIntent();
        Window newWindow = manager.startActivity(stack.peek(), lastIntent);
        setContentView(newWindow.getDecorView());
    }
}

TabActivity.java

public class TabActivity extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab_screen);
        TabHost tabHost = getTabHost();
        Intent intent = new Intent().setClass(this, ActivityStack.class);
        TabHost.TabSpec spec = tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.home));
        spec.setContent(intent);

        tabHost.addTab(spec);

        Intent intent1 = new Intent().setClass(this, ActivityStack.class);
        TabHost.TabSpec spec1 = tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.invoice));
        spec1.setContent(intent1);
        tabHost.addTab(spec1);

        tabHost.setCurrentTab(0);
    }
}

FirstActivity.java

public class FirstActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView textView = new TextView(this);
        textView.setText("Tab Sample Activity ");
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setClass(getParent(), SecondActivity.class);
                ActivityStack activityStack = (ActivityStack) getParent();
                activityStack.push("SecondActivity", intent);
            }
        });
        setContentView(textView);
    }
}

SecondActivity.java

public class SecondActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView textView = new TextView(this);
        textView.setText("First Stack Activity ");
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setClass(getParent(), ThirdActivity.class);
                ActivityStack activityStack = (ActivityStack) getParent();
                activityStack.push("ThirdActivity", intent);
            }
        });
        setContentView(textView);
    }
}

ThirdActivity.java

public class ThirdActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

在res/layout文件夹下设置XML 文件 1) tab_screen.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"

        <FrameLayout

            android:layout_above="@android:id/tabs"
            android:layout_weight="1" />

        <TabWidget

</LinearLayout>
