How to use setImageUri() on Android

Question

Can you help me please? I\'ve tried :

ImageButton imgbt=(ImageButton)findViewById(R.id.imgbutton);
Uri imgUri=Uri.parse(\"/data/data/MYFOLDER/myimage.png\");         


        

Answer 1

Its best to avoid building the path by hand, try :

imgbt.setImageUri(Uri.fromFile(new File("/data/data/....")));

Answer 2

ImageView.setImageUri only works for local Uri, ie a reference to a local disk file, not a URL to an image on the network.

Here is an example of how to fetch a Bitmap from the network.

    private Bitmap getImageBitmap(String url) {
        Bitmap bm = null;
        try {
            URL aURL = new URL(url);
            URLConnection conn = aURL.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            bm = BitmapFactory.decodeStream(bis);
            bis.close();
            is.close();
       } catch (IOException e) {
           Log.e(TAG, "Error getting bitmap", e);
       }
       return bm;
    } 

Once you have the Bitmap from getImageBitmap(), use: imgView.setImageBitmap(bm);

Answer 3

It should be

Uri imgUri=Uri.parse("file:///data/data/MYFOLDER/myimage.png");

Answer 4

I also met this issue, it did not show anything. I saw something like this in android developer. It didn't use setImageURI.

private Bitmap getBitmapFromUri(Uri uri, Context context) throws IOException {
    ParcelFileDescriptor parcelFileDescriptor =
            context.getContentResolver().openFileDescriptor(uri, "r");
    FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
    Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
    parcelFileDescriptor.close();
    return image;
}

Just for your reference.

Answer 5

I solved it with framework. Added this line into the gradle:

implementation 'com.facebook.fresco:fresco:1.8.0'

Init singlton in application-class(or another main class in your app)

Fresco.initialize(applicationContext)

And in finish, use it.

XML:

 <com.facebook.drawee.view.SimpleDraweeView
  android:id="@+id/avatar"
  android:layout_width="110dp"
  android:layout_height="110dp" /> 

Java:

avatar.setImageURI(user.getAvatarUrl())

Answer 6

How about this one:

Bitmap bitmap = BitmapFactory.decodeFile(fullFileName);
imgProfileImage.setImageBitmap(bitmap);
