ActivityGroup简介

ActivityGroup效果和TabHost效果类似。TabHost限制较多，自己定制不容易使用。

下面举例说明一下ActivityGroup的使用。

两个按钮，点击不同按钮切换不同的activity。

private Button button1;
    private Button button2;
    private LinearLayout container;
    private OnClickListener l = new OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch(v.getId()){
            case R.id.button1:
                switchActivity(0);
                break;
            case R.id.button2:
                switchActivity(1);
                break;
            }
        }

    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        button1 = (Button)findViewById(R.id.button1);
        button2 = (Button)findViewById(R.id.button2);
        container = (LinearLayout) findViewById(R.id.container);


        button1.setOnClickListener(l);
        button2.setOnClickListener(l);

        switchActivity(0);
    }

    private void switchActivity(int id){
        container.removeAllViews();
        Intent intent = null;
        switch(id){
        case 0:
            intent = new Intent(this,TestActivity1.class);
            break;
        case 1:
            intent = new Intent(this,TestActivity2.class);
            break;
        }

        Window  subActivity = getLocalActivityManager().startActivity("subActivity", intent);
        container.addView(subActivity.getDecorView(),LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    }

xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout android:orientation="horizontal"
        android:layout_width="fill_parent" android:layout_height="wrap_content">
        <Button android:id="@+id/button1" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:text="窗体1" />
        <Button android:id="@+id/button2" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:text="窗体2" />
    </LinearLayout>
    <LinearLayout android:id="@+id/container" android:orientation="horizontal"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:background="#0000ff">
    </LinearLayout>
</LinearLayout>
