要求点击底部不同图片按钮切换不同的Activity，并在中间显示Activity对应的ContentView。
二、 实现代码
2.1 layout.xml

/** * 使用ActivityGroup来切换Activity和Layout * @author 农民伯伯 * @version 2010-9-7 * */public class TestView extends ActivityGroup { private ScrollView container = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 隐藏标题栏 requestWindowFeature(Window.FEATURE_NO_TITLE); // 设置视图 setContentView(R.layout.layout); container = (ScrollView) findViewById(R.id.containerBody); // 模块1 ImageView btnModule1 = (ImageView) findViewById(R.id.btnModule1); btnModule1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { container.removeAllViews(); container.addView(getLocalActivityManager().startActivity( "Module1", new Intent(TestView.this, ModuleView1.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) .getDecorView()); } }); // 模块2 ImageView btnModule2 = (ImageView) findViewById(R.id.btnModule2); btnModule2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { container.removeAllViews(); container.addView(getLocalActivityManager().startActivity( "Module2", new Intent(TestView.this, ModuleView2.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) .getDecorView()); } }); // 模块3 ImageView btnModule3 = (ImageView) findViewById(R.id.btnModule3); btnModule3.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { container.removeAllViews(); container.addView(getLocalActivityManager().startActivity( "Module3", new Intent(TestView.this, ModuleView3.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) .getDecorView()); } }); }}代码说明：
- ModuleView1、ModuleView2、 ModuleView3分别继承自Activity。
- 想动态改变标题可以通过cust_title获取TextView进行设置。
