Android Marshmallow-Berechtigungen?

Question

Ich möchte Erlaubnisaufforderung zeigen, wo Benutzer den Zugang dieser Erlaubnis annehmen kann, Wie ich auf Benutzerkontakte zugreifen möchte, also ich Prompt mit zwei anzeigen will, erlaube und leugne irgendein Beispiel und Quellcode.

Answer 1

wie tun diese

private void PerrmissionWork() { 

    List<String> permissionsNeeded = new ArrayList<String>(); 

    final List<String> permissionsList = new ArrayList<String>(); 
    if (!addPermission(permissionsList, 
      Manifest.permission.ACCESS_FINE_LOCATION)) 
     permissionsNeeded.add("GPS"); 
    if (!addPermission(permissionsList, 
      Manifest.permission.ACCESS_COARSE_LOCATION)) 
     permissionsNeeded.add("GPS COARSE"); 


    if (permissionsList.size() > 0) { 
     if (permissionsNeeded.size() > 0) { 
      // Need Rationale 
      String message = "You need to grant access to " 
        + permissionsNeeded.get(0); 
      for (int i = 1; i < permissionsNeeded.size(); i++) 
       message = message + ", " + permissionsNeeded.get(i); 
      showMessageOKCancel(message, 
        new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, 
           int which) { 
          requestPermissions(permissionsList 
            .toArray(new String[permissionsList 
              .size()]), 
            REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS); 
         } 
        }); 
      return; 
     } 
     requestPermissions(
       permissionsList.toArray(new String[permissionsList.size()]), 
       REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS); 
     return; 
    } 
    splashMainWork(); 
} 

// mapWork(); 

private boolean addPermission(List<String> permissionsList, 
     String permission) { 
    if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) { 
     permissionsList.add(permission); 
     // Check for Rationale Option 
     if (!shouldShowRequestPermissionRationale(permission)) 
      return false; 
    } 
    return true; 
} 

private void showMessageOKCancel(String message, 
     android.content.DialogInterface.OnClickListener onClickListener) { 
    new AlertDialog.Builder(context).setMessage(message) 
      .setPositiveButton("OK", onClickListener).setCancelable(false) 
      .setNegativeButton("Cancel", null).create().show(); 

} 

@Override 
public void onRequestPermissionsResult(int requestCode, 
     String[] permissions, int[] grantResults) { 
    switch (requestCode) { 
    case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS: { 
     Map<String, Integer> perms = new HashMap<String, Integer>(); 
     // Initial 
     perms.put(Manifest.permission.ACCESS_FINE_LOCATION, 
       PackageManager.PERMISSION_GRANTED); 
     perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, 
       PackageManager.PERMISSION_GRANTED); 

     // Fill with results 
     for (int i = 0; i < permissions.length; i++) 
      perms.put(permissions[i], grantResults[i]); 
     // Check for ACCESS_FINE_LOCATION 
     if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED 
       && perms.get(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED 
       ) { 
      // All Permissions Granted 
      splashMainWork(); 
     } else { 
      // Permission Denied 
      Toast.makeText(context, "Some Permission is Denied", 
        Toast.LENGTH_SHORT).show(); 
     } 
    } 
     break; 
    default: 
     super.onRequestPermissionsResult(requestCode, permissions, 
       grantResults); 
    } 
} 

und diese Methode aufrufen, in so weiter erstellen ..

if (Build.VERSION.SDK_INT >= 23) { 
     PerrmissionWork(); 
    } else { 
     splashMainWork(); 
    } 

Ich erhalte Lage in splash Arbeitsweise und unter Verwendung von Orts Erlaubnis Sie Kontakt permisssion verwenden können, und anstelle von splash Arbeit tun Sie Ihren Kontaktcode .. und es gibt viele Demo auch verfügbar versuchen Sie Google sie können Ihnen gute Erklärungen geben .. und es gibt sehr gute Erklärung auf Entwickler sitzen auch.
here .. Try this blog very helpful

prüfen https://developer.android.com/training/permissions/requesting.html out für die offizielle Dokumentation über Berechtigungen anfordern. Hier ist eine Beispielklasse mit dieser Dokumentation:

public class PermissionCheck { 


    private void requestIfNeeded() { 
     // Here, thisActivity is the current activity 
     if (ContextCompat.checkSelfPermission(thisActivity, 
         Manifest.permission.READ_CONTACTS) 
       != PackageManager.PERMISSION_GRANTED) { 

      // Should we show an explanation? 
      if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
        Manifest.permission.READ_CONTACTS)) { 

       // Show an expanation to the user *asynchronously* -- don't block 
       // this thread waiting for the user's response! After the user 
       // sees the explanation, try again to request the permission. 

      } else { 

       // No explanation needed, we can request the permission. 

       ActivityCompat.requestPermissions(thisActivity, 
         new String[]{Manifest.permission.READ_CONTACTS}, 
         MY_PERMISSIONS_REQUEST_READ_CONTACTS); 

       // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
       // app-defined int constant. The callback method gets the 
       // result of the request. 
      } 
     } 
    } 

    @Override 
    public void onRequestPermissionsResult(int requestCode, 
      String permissions[], int[] grantResults) { 
     switch (requestCode) { 
      case MY_PERMISSIONS_REQUEST_READ_CONTACTS: { 
       // If request is cancelled, the result arrays are empty. 
       if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        // permission was granted, yay! Do the 
        // contacts-related task you need to do. 
        handleSuccessfulPermissionsRequest(); 

       } else { 

        // permission denied, boo! Disable the 
        // functionality that depends on this permission. 
        handlePermissionDenied(); 
       } 
       return; 
      } 

      // other 'case' lines to check for other 
      // permissions this app might request 
     } 
    } 

    private void handleSuccessfulPermissionsRequest() { 
      Toast.makeText(this, "Request Successful!",Toast.LENGTH_SHORT).show(); 
    } 

    private void handlePermissionDenied() { 
     Toast.makeText(this, "Request Denied!",Toast.LENGTH_SHORT).show(); 
    } 

}
