Android使用ListView展示清單資料

效果：

總體部局檔案：activity_act_car_info.xml

<?xml version="1.0" encoding="utf-8"?> 

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

   android:id="@android:id/list" 

    android:layout_width="fill_parent" 

    android:layout_height="fill_parent" 

    android:background="#ffffff" 

   > 

</ListView>

布局檔案：carinfolayout.xml

<?xml version="1.0" encoding="utf-8"?> 

<RelativeLayout 

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

  android:layout_width="fill_parent" 

  android:layout_height="wrap_content"> 

  <TextView    

    android:id="@+id/text1" 

    android:layout_alignParentLeft="true" 

    android:layout_width="wrap_content" 

    android:layout_height="wrap_content"/> 

  <ImageView   

    android:id="@+id/image" 

    android:layout_alignParentRight="true" 

    android:layout_width="wrap_content" 

    android:layout_height="wrap_content"/> 

</RelativeLayout>
