android tabwidget意图标签刷新每个命中

我想使用具有意图的子选项卡创建一个选项卡,以便当用户点击选项卡内容时刷新.

每次用户单击选项卡时,我想刷新并调用onrereate方法的子意图选项卡.

public class Tabs3 extends tabactivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final TabHost tabHost = getTabHost();

        tabHost.addTab(tabHost.newTabSpec("tab1")
                .setIndicator("list")
                .setContent(new Intent(this,List1.class)));

        tabHost.addTab(tabHost.newTabSpec("tab2")
                .setIndicator("photo list")
                .setContent(new Intent(this,List8.class)));

        // This tab sets the intent flag so that it is recreated each time
        // the tab is clicked.
        tabHost.addTab(tabHost.newTabSpec("tab3")
                .setIndicator("destroy")
                .setContent(new Intent(this,Controls2.class)
                        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));
    }
}

解决方法

添加.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)实现了所需的事情.
