我正在使用viewflipper进行fling手势识别,一切正常,但是在2.2和2.1中它抛出异常,因为"java.lang.IllegalArgumentException:Receiver not registered:android.widget.ViewFlipper"下面是完整的调试跟踪.

我需要在列表视图行中设置备用颜色,但是当我这样做时,它会删除/禁用焦点默认的黄色背景

我尝试使用backgroundColor rowView.setBackgroundColor(SOME COLOR);

还有backgrounddrwable.

rowView.setBackgroundColor(R.drawable.view_odd_row_bg);

Run Code Online (Sandbox Code Playgroud)

<?xml version="1.0" encoding="utf-8"?>
<selector
   xmlns:android="http://schemas.android.com/apk/res/android">
   <item
      android:state_window_focused="false"
      android:drawable="@color/odd" />

   <!--
      Even though these two point to the same resource, have two states
      so the drawable will invalidate itself when coming out of pressed
      state.
   -->
   <item
      android:state_focused="true"
      android:state_enabled="false"
      android:state_pressed="true"
      android:drawable="@color/highlight" />
   <item
      android:state_focused="true"
      android:state_enabled="false"
      android:drawable="@color/highlight" />

   <item
      android:state_focused="true"
      android:state_pressed="true"
      android:drawable="@color/highlight" />
   <item
      android:state_focused="false"
      android:state_pressed="true"
      android:drawable="@color/highlight" />

   <item
      android:state_focused="true"
      android:drawable="@color/highlight" />

</selector>

但它不会工作.

我们有什么办法可以同时设置背景颜色和焦点颜色.
