android tabwidget意图选项卡刷新每一个命中

Question

我想使用具有意图的子选项卡创建一个选项卡，这样当用户点击标签意图时就会刷新。

每次用户点击标签我想要刷新并调用oncreate方法的子意图标签。

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)));
    }
}

Answer 1

添加.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)符合要求。
