onActivityResult() 没有在片段中调用
onActivityResult() is not calling in fragment
我要分段扫描二维码
但是 onActivityResult 没有调用。
Fragment.java
@Override
public View onCreateView(LayoutInflater inflater ,ViewGroup container ,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate( R.layout.fragment_offer ,container ,false );
scanOffer = view.findViewById( R.id.scanOffer );
scanOffer.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View view) {
scanBarcode();
}
} );
return view;
}
public void scanBarcode() {
/** This method will listen the button clicked passed form the fragment **/
Intent intent = new Intent(getContext(),CaptureActivity.class);
intent.setAction("com.google.zxing.client.android.SCAN");
intent.putExtra("SAVE_HISTORY", false);
startActivityForResult(intent, 0);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0) {
if (resultCode == Activity.RESULT_OK) {
uniqueCode = data.getStringExtra("SCAN_RESULT");
Log.d(TAG, "contents: " + uniqueCode);
Toast.makeText( getContext() ,uniqueCode ,Toast.LENGTH_SHORT ).show();
// callAddStoreContestParticipantService();
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.d(TAG, "RESULT_CANCELED");
}
}
}
请帮帮我。
onActivityResult() 没有调用
CaptureActivity.class扫描后打开Qr onActivityResult()未调用
你必须打电话给 getActivity().startActivityForResult(intent, 0);
在你的片段中
在你的 activity 你在 onActivityResultMethod()
你必须打电话给 yourfragmnt.onActivityResult()
尝试使用以下代码进行条形码扫描,并在 activity 上重写父 activity
结果
private static final int BARCODE_REQUEST = 312;
private void startBarcode() {
//IntentIntegrator.forFragment(getActivity().initiateScan()); // `this` is the current Fragment
IntentIntegrator integrator = new IntentIntegrator(getActivity()) {
@Override
protected void startActivityForResult(Intent intent, int code) {
Fragment.this.startActivityForResult(intent, BARCODE_REQUEST); // REQUEST_CODE override
}
};
//IntentIntegrator integrator = new IntentIntegrator(getActivity());
//IntentIntegrator.forSupportFragment(this);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt("Scan a barcode");
integrator.setCameraId(0); // Use a specific camera of the device
integrator.setBeepEnabled(true);
integrator.setBarcodeImageEnabled(true);
integrator.setOrientationLocked(false);
integrator.setTimeout(15000);
integrator.initiateScan();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case BARCODE_REQUEST:
IntentResult Result = IntentIntegrator.parseActivityResult(IntentIntegrator.REQUEST_CODE, resultCode, data);
if (Result != null) {
if (Result.getContents() == null) {
Timber.i("cancelled scan");
showSnackbar("cancelled scan", true);
} else {
Timber.i("Scanned");
showSnackbar("Code scan successfully", false);
try {
long id = Long.parseLong(Result.getContents());
// getFood(id);
searchBarcode(Result.getContents());
} catch (Exception e) {
e.printStackTrace();
}
// searchBarcode(Result.getContents());
//getFood(Long.valueOf(mItem.get(position - 1).getID()));
}
} else {
showSnackbar("Barcode not scanned", true);
Timber.i("Barcode Result is NULL");
super.onActivityResult(requestCode, resultCode, data);
}
break;
}
}
