Question

我选择一张图片，只有Google照片返回，找不到商品。

这是创建用于选择照片的意图的代码：

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

遵循我的activityresult代码：

 @Override
        public void onActivityResult(int requestCode, int resultCode, final Intent data) {
            // TODO Auto-generated method stub
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == RESULT_OK) {
                switch (requestCode) {
                    case REQUEST_CODE_FROM_GALLERY:
                        Utils.toast_center(Main_Theme.this,""+data.getData());
                        try {
                            String root = Environment.getExternalStorageDirectory().toString();
                            File mydir = new File(root + "/Image");
                            mydir.mkdirs();
                            String fname = "user_image.jpg";
                            final File file = new File(mydir, fname);
                            Intent intent1 = new Intent("com.android.camera.action.CROP");
                            intent1.setType("image/*");
                            intent1.setData(data.getData()); // Uri to the image you want to crop
                            intent1.putExtra("scale", true);
                            intent1.putExtra("circleCrop", new String(""));
                            intent1.putExtra("return-data", false);
                            intent1.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
                            startActivityForResult(intent1, 03);
                        }catch (ActivityNotFoundException e){
                            Utils.toast_center(Main_Theme.this,"Something Went Error. Try Again");
                        }
                        break;
                    case 03:

                        File filee = new File(Environment.getExternalStorageDirectory().toString() + "//Image/user_image.jpg");

                        Bitmap bmp = BitmapFactory.decodeFile(filee.getPath());
                        iconn.setImageBitmap(bmp);
                        settheame();
                        break;
                }
            }
        }

如何解决这个问题？

当您选择Google照片图像时，URI开始就像"content://com.google.android.apps.photos.content/"，而不是来自本地设备。

本地uri，例如content://media/external/images/media/49518

因此，您需要首先检查URI，然后基于该URI从服务器或本地图像中获取图像。

您可以使用DocumentsProvider API。

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

选择Google图片，然后选择图片并对其进行裁剪
