实现类似Tab选项卡功能关键代码

//放置显示不同Activity的控件

private LinearLayout mainContentLayout;
private LocalActivityManager localActivityManager = null;

mainContentLayout = (LinearLayout)findViewById(R.id.main_content);

/*
 *    id为传入的唯一标识, activityClass为要打开的activity.class
 *　　 必须继承ActivityGroup
 */
public void setContainerView(String id, Class<?> activityClass){
  mainContentLayout.removeAllViews();
  Intent intent = new Intent(MainActivity.this, activityClass);
  localActivityManager = getLocalActivityManager();
  mainContentLayout.addView(localActivityManager.startActivity(id, intent).getDecorView());
 }
