我有一个奇怪的问题我有一个自定义列表实现，它在大多数设备中都能正常工作，但只有在少数设备中，比如 Galaxy s4 或 Grand Duos，子元素的最后一个图像不可见。
代码如下..
主列表视图：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/backgroundimage"
android:keepScreenOn="true"
android:orientation="vertical"
tools:context=".MainActivity" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:divider="#b5b5b5"
android:dividerHeight="1dp"
android:listSelector="@drawable/list_selector" />
</LinearLayout>
子元素代码：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/list_selector"
android:orientation="horizontal"
>
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<ImageView
android:id="@+id/list_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:src="@drawable/ic_launcher" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/App_Name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/list_image"
android:layout_toRightOf="@+id/list_image"
android:scrollHorizontally="false"
android:text="Rihanna Love the way lie"
android:textColor="#040404"
android:textSize="12dip"
android:textStyle="bold"
android:typeface="serif" />
<TextView
android:id="@+id/App_Desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/App_Name"
android:layout_below="@+id/App_Name"
android:scrollHorizontally="false"
android:text="Just gona stand there and ..."
android:textColor="#343434"
android:textSize="10dip"
android:typeface="monospace" />
</LinearLayout>
<ImageView
android:id="@+id/Price"
android:layout_width="20dip"
android:layout_height="60dip"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/buy_gas" />
</LinearLayout>
</RelativeLayout>

static class ViewHolder{

列表视图实现：
BinderData bindingData = new BinderData(this,songsList);
list = (ListView) findViewById(R.id.list);
list.setAdapter(bindingData);
请帮助我们。
