TableWidget

Activity代码：

 

//注意这个activity继承的是TabActivity
public class TabWidgetActivity extends TabActivity {

    //声明TabHost对象
    private TabHost mTabHost;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab_widget);

        //获取TabHoast对象
        mTabHost=getTabHost();
        /* 为TabHost添加标签 */
        //新建一个newTabSpec(newTabSpec)
        //设置其标签和图标(setIndicator)
        //设置内容(setContent)
        mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("TAB1",getResources().getDrawable(R.drawable.img1)).setContent(R.id.textview1));
        mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("TAB2",getResources().getDrawable(R.drawable.img2)).setContent(R.id.textview2));
        mTabHost.addTab(mTabHost.newTabSpec("tab_test3").setIndicator("TAB3",getResources().getDrawable(R.drawable.img3)).setContent(R.id.textview3));

        //设置TabHost的背景颜色
        mTabHost.setBackgroundColor(Color.argb(150, 22, 70, 150));

        //显示第一个tab
        mTabHost.setCurrentTab(0);

      //标签切换事件处理，setOnTabChangedListener
        mTabHost.setOnTabChangedListener(new OnTabChangeListener() {
            @Override
            public void onTabChanged(String tabId) {
                // TODO Auto-generated method stub
                Dialog dialog=new AlertDialog.Builder(TabWidgetActivity.this)
                .setTitle("提醒你")
                .setMessage("你当前选中的是"+tabId+"标签！")
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(TabWidgetActivity.this, "你单击了确定按钮！", Toast.LENGTH_LONG).show();
                        dialog.cancel();
                    }
                })
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(TabWidgetActivity.this, "你单击了取消按钮！", Toast.LENGTH_LONG).show();
                        dialog.cancel();
                    }
                })
                .create();
                dialog.show();
            }
        });
    }

}

xml配置文件：

<TabHost
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"/>
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">
            <TextView
                android:id="@+id/textview1"

                android:text="第一个tab"/>
            <TextView

                android:text="第二个tab"/>
            <TextView
                android:id="@+id/textview3"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:text="第三个tab"/>
        </FrameLayout>
    </LinearLayout>
</TabHost>
