我一直在寻找这个问题，但是我找不到并回答，我发现这是KitKat上的一个问题和一些可能的解决方案，但我发现尝试裁剪从画廊中选择的图像。 我不知道如何解决它，提前感谢有人能给我的任何帮助。
当我已经获得所选的照片数据时，从onActivityResult调用裁剪方法。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null) {
switch (requestCode) {
case CROP_FROM_CAMERA:
Bundle extras = data.getExtras();
mIsGallery = false;
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
extras.putString(AppConstants.PHOTO_URI, getImageUri(photo).toString());
extras.putParcelable(AppConstants.EVENT_DATA, mEventDetails);
CameraFilters cameraFilters = new CameraFilters();
cameraFilters.setArguments(extras);
mFragmentManager.beginTransaction()
.replace(R.id.content_frame, cameraFilters)
.addToBackStack(AppConstants.CUSTOM_CAMERA_FRAGMENT).commit();
}
break;
case MEDIA_TYPE_GALLERY:
mImageCaptureUri = data.getData();
doCrop();
break;
}
}
}
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getActivity().getPackageManager().queryIntentActivities(intent, 0);
int size = list.size();
if (size == 0) {
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_SHORT);
toast.show();
} else {
intent.setData(mImageCaptureUri);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
} else {
for (ResolveInfo res : list) {
final CropOption co = new CropOption();
co.title = getActivity().getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getActivity().getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent= new Intent(intent);
co.appIntent.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getActivity().getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Choose Crop App");
builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
public void onClick( DialogInterface dialog, int item ) {
startActivityForResult( cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener( new DialogInterface.OnCancelListener() {
@Override
public void onCancel( DialogInterface dialog ) {
if (mImageCaptureUri != null ) {
getActivity().getContentResolver().delete(mImageCaptureUri, null, null );
mImageCaptureUri = null;
}
}
} );
AlertDialog alert = builder.create();
alert.show();
}
}
}
