android tabwidget 意图标签刷新每次点击 [英] android tabwidget intent tabs refresh every hit

问题描述

我想使用具有意图的子选项卡创建一个选项卡，以便当用户单击选项卡意图时刷新.

I want to create a tab using child tab having intents, so that when ever user click on tabs intents get refresh.

每次用户单击选项卡时，我都想刷新并调用子意图选项卡的 oncreate 方法.

Every time user click on tab i want to refresh and called oncreate method of child intent tabs.

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)));
    }
}
