所以我有2个活动，第一个活动是在第二个活动开始之前启动相机。拿完相机后，第二活动上的ImageView将根据所拍摄的照片而改变。而且，如果我单击ImageView，它将使相机对准并替换相机中的图像。但是，我每次拍照后都无法替换ImageView上的图像，并且resultCode始终为0。
这是第一个活动
@OnClick(R.id.fab_toko)
private void create_ticket() {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(Consts.MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
startActivityForResult(intent, Consts.CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
public Uri getOutputMediaFileUri(int type) {
return Uri.fromFile(getOutputMediaFile(type));
//return FileProvider.getUriForFile(MainActivity.this, MainActivity.this.getApplicationContext().getPackageName(), getOutputMediaFile(type));
}
/**

private static File getOutputMediaFile(int type) {
// External sdcard location
File mediaStorageDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
Consts.IMAGE_DIRECTORY_NAME);
//Creating an internal dir;
File mDir = RumahkeduaApplication.getContext().getDir("ISS", Context.MODE_PRIVATE);
//Internal Storage
// File mediaInternalDir = new File(mDir,Consts.IMAGE_DIRECTORY_NAME);
File mediaInternalDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
// Create the storage directory if it does not exist
if (!mediaInternalDir.exists()) {
if (!mediaInternalDir.mkdirs()) {
Log.d(TAG, "Oops! Failed create "
+ Consts.IMAGE_DIRECTORY_NAME + " directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
File mediaFile;
if (type == Consts.MEDIA_TYPE_IMAGE) {
mediaFile = new File(mediaInternalDir.getPath() + File.separator
+ "IMG_" + timeStamp + ".jpg");
} else {
return null;
}
return mediaFile;
}
/**

@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// save file url in bundle as it will be null on screen orientation
outState.putParcelable("file_uri", fileUri);
}

mainIntent.putExtra("id_user", login_user.getId_user());

这是第二个活动
