小编ale*_*sev的帖子

这必须是一些非常简单的我忽略,但我有以下问题(帖子相当冗长,但我想提供尽可能多的信息:)).

我的Android应用程序中有一个gridview,每个单元格都有自定义视图:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  >
    <GridView
    android:id = "@+id/photosGridView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:clickable="true" 
    android:drawSelectorOnTop="true" 
    android:focusable="true" 
    android:focusableInTouchMode="true" 
    android:numColumns="6" 
    android:columnWidth="90dp"
    android:verticalSpacing="5dp"
    android:horizontalSpacing="5dp"
    android:stretchMode="columnWidth"     
    >
</GridView>

</RelativeLayout>

每个细胞都是

<?xml version="1.0" encoding="utf-8"?>
<com.myapp.widgets.ImageThumbView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background = "@android:color/transparent"
  android:paddingLeft = "1dip"
  android:paddingRight = "1dip"
  android:paddingTop = "2dip"
  android:paddingBottom = "2dip"
  >
<ImageView
    android:id="@+id/thumbImage"
    android:layout_width="fill_parent"
    android:layout_height = "fill_parent"
    android:src="@drawable/icon_small"
    /> 

  <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height = "fill_parent"
    android:background = "@android:color/transparent"
   >

  <ImageView
   android:id="@+id/iconRight"
   android:layout_width="40px"
   android:layout_height = "40px"  
   android:src="@drawable/album_check"
   android:visibility="gone"
   android:layout_alignParentTop = …
