Android常见的错误整理（不定时更新）

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 FrameLayout
java.lang.NoSuchMethodError: android.widget.FrameLayout.setBackground()
ByteArrayInputStream imageStream2= new ByteArrayInputStream(cardbackground);

Bitmap Imagebackground = BitmapFactory.decodeStream(imageStream2);

Drawable imagebakground=new BitmapDrawable(getResources(),Imagebackground);

framelayout.setBackground(imagebakground);

setBackgroundDrawable()相反用setBackground

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {

framelayout.setBackground(imagebakground);

} else {

frameLayout.setBackgroundDrawable(imagebakground);

}
