在我的应用程序中,我允许用户从他们的图库中选择个人资料图片,如下所示:
当您单击第一个选项时,在我的 Android 5.0 设备上,我得到以下信息:
如果我使用基于 AOSP 项目的普通 Gallery 应用程序,一切正常且花花公子。但是,Photo 的应用程序似乎使用了不同的意图。
以下是我处理普通画廊代码的方式:
Intent photoPickerIntent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
photoPickerIntent.setType("image/*");
photoPickerIntent.putExtra("crop", "true");
photoPickerIntent.putExtra("outputX", 300);
photoPickerIntent.putExtra("outputY", 300);
photoPickerIntent.putExtra("aspectX", 1);
photoPickerIntent.putExtra("aspectY", 1);
photoPickerIntent.putExtra("scale", true);
photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
photoPickerIntent.putExtra("outputFormat",
Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(photoPickerIntent, RESULT_LOAD_IMAGE);
然后是意图结果处理程序:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RESULT_LOAD_IMAGE
&& resultCode == Activity.RESULT_OK) {
if (data != null) {
tempFile = getTempFile();
filePath = Environment.getExternalStorageDirectory() + "/"
+ "temporary_holder.jpg";
Log.d("LOAD REQUEST filePath", filePath);
Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
iPP.setImageBitmap(selectedImage);
}
imagePath = filePath;
new UploadImage().execute();
}
}
上面的一些辅助函数:
private static Uri getTempUri() {
return Uri.fromFile(getTempFile());
}
private static File getTempFile() {
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {
File file = new File(Environment.getExternalStorageDirectory(),
"temporary_holder.jpg");
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
return file;
}
return null;
}
其中一些可能不需要显示,但我将其全部包含在内,以防干扰。
当我使用 Google Photos 挑选照片时,我的 ImageView 是空白的(而不是用选定的挑选填充)。未选择图像,我无法像在图库中设置的那样进入手动裁剪视图。 所以基本上,什么都没有发生。
响应答案的新代码
photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
photoPickerIntent.putExtra("crop", "true");
photoPickerIntent.putExtra("outputX", 300);
photoPickerIntent.putExtra("outputY", 300);
photoPickerIntent.putExtra("aspectX", 1);
photoPickerIntent.putExtra("aspectY", 1);
photoPickerIntent.putExtra("scale", true);
photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
photoPickerIntent.putExtra("outputFormat",
Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(photoPickerIntent, RESULT_LOAD_IMAGE);
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (data != null) {
Log.i("data", data.toString());
switch (requestCode) {
case RESULT_LOAD_IMAGE:
Log.i("RESULT_LOAD_IMAGE", "MARK");
// Received an image from the picker, now send an Intent for cropping
final String CROP_ACTION = "com.android.camera.action.CROP";
Intent photoCropIntent = new Intent(CROP_ACTION);
photoCropIntent.putExtra("crop", "true");
photoCropIntent.putExtra("aspectX", 1);
photoCropIntent.putExtra("aspectY", 1);
photoCropIntent.putExtra("outputX", 300);
photoCropIntent.putExtra("outputY", 300);
photoCropIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
photoCropIntent.putExtra("outputFormat",
Bitmap.CompressFormat.JPEG.toString());
photoCropIntent.setData(data.getData());
startActivityForResult(photoPickerIntent, RESULT_CROP_IMAGE);
break;
case RESULT_CROP_IMAGE:
Log.i("RESULT_CROP_IMAGE", "MARK");
tempFile = getTempFile();
imagePath = Environment.getExternalStorageDirectory() + "/" + "temporary_holder.jpg";
Log.i("imagePath", imagePath);
Uri selectedImageURI = data.getData();
InputStream image_stream;
try {
image_stream = getActivity().getContentResolver().openInputStream(selectedImageURI);
Bitmap bitmap = BitmapFactory.decodeStream(image_stream);
iPP.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
new UploadImage().execute();
break;
default:
// Handle default case
}
}
}
}
上面的代码也不起作用。我试图使它类似于下面的答案。会发生什么:
我单击“从图库中选择”。它不再给我选择,现在它直接从库存画廊打开(这没什么大不了的)。我单击图像,它......似乎重新开始intent
- 它带回画廊希望我选择另一个图像:而不是 Cropping Activity
。然后在第二次之后,它将ImageView
使用所选文件设置我的。
