1.将Bitmap影像到FrameLayout，我解码的图像转换成Drawable，然后将其设置为背景的FrameLayoutjava.lang.NoSuchMethodError:android.widget.FrameLayout.setBackground()ByteArrayInputStreamp_w_picpathStream2=newByteArrayInputStream(cardbackground);BitmapImagebackground=BitmapFactory.decodeStream(p_w_picpathStream2);Drawablep_w_picpathbakground=newBitmapDrawable(getResources(),Imagebackground);framelayout.setBackground(p_w_picpathbakground);

解决方法：setBackground()方法，在添加 API 级别 16。使用 setBackgroundDrawable()相反用setBackground

if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN){framelayout.setBackground(p_w_picpathbakground);}else{frameLayout.setBackgroundDrawable(p_w_picpathbakground);}
