Android - 대화 상자 단편 해제

Question

나는 imageview를 포함하는 활동이 있습니다. 해당 이미지를 클릭하면 html 콘텐츠와 버튼으로 구성된 대화 상자 조각이 표시됩니다. 해당 버튼을 클릭하면이 대화 상자 조각을 닫고 싶습니다. dismiss() 함수를 사용하려고했지만 쓸모가 없었습니다. 대화 상자 조각이 닫히지 않고 실제로 새로 고쳐지며 버튼을 3-4 번 터치 한 후 닫히는 경우가 있습니다.

는 다음 활동에 대한 내 코드입니다 :

public class MainActivity extends FragmentActivity implements OnMapReadyCallback,GeneralCallback { 
private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1; 
private Polyline line; 
private GoogleMap googleMap; 
private Controller controller; 
private JSONObject UserDetails; 
private JSONArray routePath; 
private JSONArray stopPoints; 
private List<LatLng> pointsRoutePath; 
private List<LatLng> pointsStopPoints; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    controller=new Controller(this); 

    requireLocationPermissions(); 

    initializeGoogleMap(); 

    configureImage(); 
} 


@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) { 
    switch (requestCode) { 
     case REQUEST_ID_MULTIPLE_PERMISSIONS: { 
      Map<String, Integer> perms = new HashMap<String, Integer>(); 
      // Initialize the map with both permissions 
      perms.put(android.Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED); 
      perms.put(android.Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED); 

      // Fill with actual results from user 
      if (grantResults.length > 0) { 
       for (int i = 0; i < permissions.length; i++) 
        perms.put(permissions[i], grantResults[i]); 
      } 
     } 
    } 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 
    setZoomedLocation(googleMap); 
    controller.getUserDetails(); 
    this.googleMap=googleMap; 
} 

//This function is used to require location permissions from the user during run time. 
private void requireLocationPermissions(){ 
    RequestPermissions requestPermissions = new RequestPermissions(this, this); 
    requestPermissions.checkAndRequestPermissions(); 
} 

//This function is used to initialize Google Map Fragment 
private void initializeGoogleMap(){ 
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 
    mapFragment.getMapAsync(this); 
}

       decodePoly(); 
       drawPath(); 
       putStopMarkers(); 
      } 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
    } 
    else if(data.equals("AboutUs")){ 
     Log.i("onResponse","Callback"); 
     AboutUs aboutUs = (AboutUs) getSupportFragmentManager().findFragmentByTag("AboutUs"); 
     if(aboutUs!=null && response!=null) 
      aboutUs.initializeContent(response); 
    } 
} 

@Nullable 
private JSONArray getRoutePath(){ 
    try {

      return UserDetails.getJSONObject("bus").getJSONObject("route").getJSONArray("routePath");

    } 
} 

private void setZoomedLocation(GoogleMap googleMap){ 
    LocListener locationListener=new LocListener(this); 

    //checks if location permission is granted 
    if(locationListener.canGetLocation()){ 
     googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(locationListener.getLatitude(), locationListener.getLongitude()), 14.0f)); 
    } 
    LatLng point=new LatLng(locationListener.getLatitude(),locationListener.getLongitude()); 

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.marker_hi); 
    bitmap=Bitmap.createScaledBitmap(bitmap,bitmap.getWidth()/10,bitmap.getHeight()/10,false);

    aboutUs.setOnTouchListener(new View.OnTouchListener() {

      controller.aboutUS(); 
      return true;

}

여기에 대화 조각에 대한 내 코드입니다 : 여기

public class AboutUs extends DialogFragment{ 
Controller controller; 
private View view; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    view = inflater.inflate(R.layout.about_us, container, false); 
    controller = new Controller(getActivity()); 
    configureBackButton(); 
    return view; 
} 

private void configureBackButton(){ 
    Button backButton=view.findViewById(R.id.backButton); 
    backButton.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      Log.i("onTouch","onTouch"); 
      getDialog().dismiss(); 
      return true; 
     } 
    }); 
} 

public void initializeContent(JSONObject response){ 
    try { 
     String content=response.getJSONArray("InnerData").getJSONObject(0).getString("content"); 
     WebView webView = view.findViewById(R.id.html); 
     webView.loadDataWithBaseURL(null, content, "text/html", "utf-8", null); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    controller.aboutUS(); 
} 

@Override 
public void onDismiss(DialogInterface frag) { 
    dismissAllowingStateLoss(); 
    // DO Something 
}

Answer 1

backButton에있는 onTouchListener을 onClickListener으로 바꿉니다.

backButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       getDialog().dismiss(); 
      } 
     }); 

클릭 리스너는 버튼에 권장되는 방법입니다. 단추 및 대화 상자 조각의 동작을보다 예측 가능하고 결정 성있게 만듭니다.
