获取位图中的图像但仅返回黑色像素

Question

我试图设置它显示黑色像素的图像位图，我也尝试过图像 URI，但再次设置黑色像素但是当我调试它时，位图和 uri 图像正在获得正确的图像，但两种方法都是无法在 imageview 中设置它。

`ImageView imageView = (ImageView) rootView.findViewById(R.id.imagef);
    try
    {
        String profileImagePath = Environment.getExternalStorageDirectory().toString() + "/MYFolder/"+ Configuration.empcode+".jpg";
        File profilepath = new File(profileImagePath);
        if(profilepath.exists())
        {

            //need to resolve
            Bitmap bmp = BitmapFactory.decodeFile(profileImagePath);

            Uri uri = Uri.fromFile(new File(profileImagePath));
//                imageView.setImageBitmap(bmp);
            imageView.setImageURI(uri);
        }
    }
    catch(Exception e)
    {
        Log.d("Profile Image Exception", e.toString());
    }
`

Answer 1

你可以使用毕加索：

    String profileImagePath = Environment.getExternalStorageDirectory().toString() + "/MYFolder/"+ Configuration.empcode+".jpg";
    File profilepath = new File(profileImagePath);
    Picasso.with(yourActivityContext).load(profilepath).into(imageView);

Answer 2

ImageView imageView = (ImageView) rootView.findViewById(R.id.imagef);
String profileImagePath = Environment.getExternalStorageDirectory().toString() + "/MYFolder/"+ Configuration.empcode+".jpg";
File profilepath = new File(profileImagePath);
Picasso.with(activity_or_fragment_context).load(profilePath).placeholder(R.drawable.any_place_holder_png_file).fit().centerCrop().into(imageView);
