关于ActivityGroup一些常用方法

1.加载子Activity到ActivityGroup中

<span style="white-space:pre"> </span>bodyView.removeAllViews();
String id = intent.getComponent().getShortClassName();
View view = getLocalActivityManager().startActivity(id, intent).getDecorView();
view.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));//此代码句将子页面铺满group中的view
view.dispatchWindowFocusChanged(true);
bodyView.addView(view);

2.将ActivityGroup中的Activity删除
<span style="white-space:pre"> </span>getLocalActivityManager().destroyActivity(id, true);

} catch(Exception e) {

}
