Android学习笔记-TabHost选项卡使用

在Android应用中，经常会用到TabHost选项卡，这里借花献佛，把apiDemo例子中的使用方法列举出来，，，

常用的方法有三种：

1. 从一个layout id创建各个tab页

public class Tabs1 extends TabActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TabHost tabHost = getTabHost();
        
        LayoutInflater.from(this).inflate(R.layout.tabs1, tabHost.getTabContentView(), true);
        tabHost.addTab(tabHost.newTabSpec("tab1")
                .setIndicator("tab1")
                .setContent(R.id.view1));
        tabHost.addTab(tabHost.newTabSpec("tab3")
                .setIndicator("tab2")
                .setContent(R.id.view2));
        tabHost.addTab(tabHost.newTabSpec("tab3")
                .setIndicator("tab3")
                .setContent(R.id.view3));
    }
}

2. 动态创建一个view来做为tab页的内容

public class Tabs2 extends TabActivity implements TabHost.TabContentFactory {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final TabHost tabHost = getTabHost();
        tabHost.addTab(tabHost.newTabSpec("tab1")
                .setIndicator("tab1", getResources().getDrawable(R.drawable.star_big_on))
                .setContent(this));
        tabHost.addTab(tabHost.newTabSpec("tab2")
                .setIndicator("tab2")
                .setContent(this));
        tabHost.addTab(tabHost.newTabSpec("tab3")
                .setIndicator("tab3")
                .setContent(this));
    }
    /** {@inheritDoc} */
    public View createTabContent(String tag) {
        final TextView tv = new TextView(this);
        tv.setText("Content for tab with tag " + tag);
        return tv;
    }
}

3. 传递一个intent来传递参数，并以新启动的activity做为tab页的内容，这个应该是比较方便传递参数的。。。

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)));
    }
}
