setImageViewUri 不显示图片，但显示 imageview 的背景

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()));             
} 

我已经检查了路径和uri，是正确的。setImageViewUri不显示图片但显示白屏（背景是白色的）。

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);
    }
