Question

我正在处理一个应用程序。我在该应用程序中有一个上传按钮。当我点击上传按钮移动图库打开然后我选择图像并将其上传到ImageView。我的应用程序在少数移动设备上工作，但是当我在三星Galexy Note3上尝试时，应用程序在将图像上传到imageview时没有响应。请帮帮我。

上传代码按钮：

upload.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent i = new Intent(
                    Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, REQ_CODE_PICK_IMAGE1);
        }
    });

onActivityResult上的代码：

switch (requestCode) {
    case REQ_CODE_PICK_IMAGE1:
        if (resultCode == RESULT_OK) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            this.path1 = picturePath;
            // iv1.setImageBitmap(BitmapFactory.decodeFile(picturePath));
            try {
                iv1.setImageBitmap(decodeBitmap(selectedImage,
                        EyeMatch.this));
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            iv1.setScaleType(ScaleType.FIT_XY);
            break;

        }

位图代码decodeBitmap：

public static Bitmap decodeBitmap(Uri selectedImage, Context context)
        throws FileNotFoundException {
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(context.getContentResolver()
            .openInputStream(selectedImage), null, o);

    final int REQUIRED_SIZE = 100;

    int width_tmp = o.outWidth, height_tmp = o.outHeight;
    int scale = 1;
    while (true) {
        if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
            break;
        }
        width_tmp /= 2;
        height_tmp /= 2;
        scale *= 2;
    }

    BitmapFactory.Options o2 = new BitmapFactory.Options();
    o2.inSampleSize = scale;
    return BitmapFactory.decodeStream(context.getContentResolver()
            .openInputStream(selectedImage), null, o2);
}

图像无法上传到Galaxy Note 3中的ImageView
