setImageViewUri不显示图片，但显示图像背景

Question

File file = new File("/storage/emulated/0/BabyCareData/photo/20160229_161413.jpg"); 
if (file.exists()) { 
    views.setImageViewUri(R.id.imageAvatar, Uri.parse(file.getPath()));    
} 

我已检查路径和uri，它是正确的。 setImageViewUri不显示图片，但显示白色屏幕（背景为白色）。

Answer 1

试试这个：

File file = new File(/storage/emulated/0/BabyCareData/photo/20160229_161413.jpg); 

if(file.exists()) 
{ 

    Bitmap myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath()); 
    setBitmap(views,R.id.imageAvatar,myBitmap); 

} 

    private void setBitmap(RemoteViews views, int resId, Bitmap bitmap){ 
     Bitmap proxy = Bitmap.createBitmap(bitmap.getWidth(),bitmap.getHeight(), Bitmap.Config.ARGB_8888); 
     Canvas c = new Canvas(proxy); 
     c.drawBitmap(bitmap, new Matrix(), null); 
     views.setImageViewBitmap(resId, proxy); 
    }
