我有一个带有以下代码的片段：

final MyActivity activity = (MyActivity )getActivity();

然后稍后：

Drawable d = (Drawable) ((Context)(activity)).getResources().getDrawable(R.drawable.marker_report_path_merge);
Bitmap b = Bitmap.createBitmap(d.getIntrinsicWidth(), d.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
LayerDrawable ld = (LayerDrawable) ((Context)(activity)).getResources().getDrawable(R.drawable.marker_report_path_merge);
ld.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
ld.draw(new Canvas(b));

我收到此错误：

但我所有的资源都存在！

我尝试在 Eclipse 中清理构建，但没有奏效。

谁能帮我？

谢谢

这是 marker_report_path_merge.xml：

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/marker_report_blue" />
    <item>
      <bitmap android:src="@drawable/report_path_merge"
              android:gravity="center_vertical|center_horizontal" />
    </item>
</layer-list>

The reason why you had this error was because you didn't have a real bitmap in your <item> tag it layer-list. You can check this code in BitmapDrawable class, inflate method

final Bitmap bitmap = BitmapFactory.decodeResource(r, id);
if (bitmap == null) {
    throw new XmlPullParserException(parser.getPositionDescription() +
            ": <bitmap> requires a valid src attribute");
}

You posted exactly this exception.
