Get content uri from file path in android

Try with:

ImageView.setImageURI(Uri.fromFile(new File("/sdcard/cats.jpg")));

Or with:

ImageView.setImageURI(Uri.parse(new File("/sdcard/cats.jpg").toString()));

UPDATE

Here it is assumed that your media (Image/Video) is already added to content media provider. If not then you will not able to get the content URL as exact what you want. Instead there will be file Uri.

I had same question for my file explorer activity. You should know that the contenturi for file only supports mediastore data like image, audio and video. I am giving you the code for getting image content uri from selecting an image from sdcard. Try this code, maybe it will work for you...

public static Uri getImageContentUri(Context context, File imageFile) {
  String filePath = imageFile.getAbsolutePath();
  Cursor cursor = context.getContentResolver().query(
      MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
      new String[] { MediaStore.Images.Media._ID },
      MediaStore.Images.Media.DATA + "=? ",
      new String[] { filePath }, null);
  if (cursor != null && cursor.moveToFirst()) {
    int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
    cursor.close();
    return Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + id);
  } else {
    if (imageFile.exists()) {
      ContentValues values = new ContentValues();
      values.put(MediaStore.Images.Media.DATA, filePath);
      return context.getContentResolver().insert(
          MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
    } else {
      return null;
    }
  }
}

For support android Q

public static Uri getImageContentUri(Context context, File imageFile) {
String filePath = imageFile.getAbsolutePath();
Cursor cursor = context.getContentResolver().query(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
        new String[]{MediaStore.Images.Media._ID},
        MediaStore.Images.Media.DATA + "=? ",
        new String[]{filePath}, null);
if (cursor != null && cursor.moveToFirst()) {
    int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
    cursor.close();
    return Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + id);
} else {
    if (imageFile.exists()) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            ContentResolver resolver = context.getContentResolver();
            Uri picCollection = MediaStore.Images.Media
                    .getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);
            ContentValues picDetail = new ContentValues();
            picDetail.put(MediaStore.Images.Media.DISPLAY_NAME, imageFile.getName());
            picDetail.put(MediaStore.Images.Media.MIME_TYPE, "image/jpg");
            picDetail.put(MediaStore.Images.Media.RELATIVE_PATH,"DCIM/" + UUID.randomUUID().toString());
            picDetail.put(MediaStore.Images.Media.IS_PENDING,1);
            Uri finaluri = resolver.insert(picCollection, picDetail);
            picDetail.clear();
            picDetail.put(MediaStore.Images.Media.IS_PENDING, 0);
            resolver.update(picCollection, picDetail, null, null);
            return finaluri;
        }else {
            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DATA, filePath);
            return context.getContentResolver().insert(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        }

    } else {
        return null;
    }
  }
