我正在尝试在运行时更改远程视图背景,我使用drawable xml来显示自定义通知。

custom_notification.xml     

 android:background="@drawable/layout_bg"
    android:layout_height="65sp"
    android:padding="10dp" >

    <ImageView android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:drawableLeft="@id/layout"
        android:layout_marginRight="10dp" />
    <TextView android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        android:textColor="@color/white"
         android:textSize="12sp"
        style="Custom Notification Title" />


</RelativeLayout>

绘制对象 - &GT; layout_bg.xml

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
   <item android:id="@+id/shape">
    <shape android:shape="rectangle">
    <stroke  android:width="3dip" />
    <corners android:radius="10dip" />
    <padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />

</shape>
</item>
</layer-list>

活动内部

   View v = findViewById(R.id.layout);
             LayerDrawable bgDrawable = (LayerDrawable)v.getBackground();
             final GradientDrawable shape = (GradientDrawable)   bgDrawable.findDrawableByLayerId(R.id.shape);
if(highstatus){
shape.setColor(R.color.highStatus);
}

如果错了,请更正。试图设置形状颜色后。我收到错误&#34;很遗憾,应用已停止&#34; 收到通知时
