ListViewバインドデータの2つの方法

1 ListViewのレイアウトこのListViewは水平線形のレイアウトを採用して、中に3つのTextViewを配置してlayoutフォルダの下で単独でこのitemを創立します.xmlはListViewのレイアウト方法を表します:layout—>new—>Android XML File

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content">
  
  <TextView
    android:layout_width="100dip"
    android:layout_height="wrap_content"
    android:id="@+id/name"
    />
  <TextView
    android:layout_width="150dip"
    android:layout_height="wrap_content"
    android:id="@+id/phone"
    />  
   <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/amount"
    />  

よく使われる指定TextViewの長さはandroid:layout_width="fill_parent"でもandroid:layout_width="150 dip"は具体的な値を指定する.3番目のTextViewでandroid:layout_width=「fill_parent」は、このTextViewが最初の2つのTextView表示後に残された画面の長さを埋めていることを示します.
