1.UI的xml檔

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity" >

   <ListView

       android:id="@+id/list"

       android:layout_width="100pt"

       android:layout_height="100pt"

       android:layout_alignParentLeft="true"

       android:layout_centerVertical="true"

       android:layout_marginLeft="26dp"

       >

   </ListView>

</RelativeLayout>

@Override

public void onItemClick(AdapterView<?> parent, View view,

int position, long id) {

Toast.makeText(getApplicationContext(),

"您點擊的是：" + ((TextView) view).getText(),

Toast.LENGTH_SHORT).show();

});

// 為ListView 設置長按監聽器

view.setOnItemLongClickListener(new OnItemLongClickListener() {

@Override
