Android Permisson Request Code Problem

Question

So fordern Sie eine Permitson? Ich habe versucht, dcumentation, aber die Konstante int Request-Code MY_PERMISSIONS_REQUEST_CALL_PHONE scheint nur zu funktionieren, noch etwas zu beachten für Rückwärtskompatibilität?

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

Wie MY_PERMISSIONS_REQUEST_CALL_PHONE Konstante int zu deklarieren?

Answer 1

Für niedrigere Versionen benötigen Sie die Berechtigung in einem offenkundigen nur zu erklären, aber für marsh müssen Sie es in den Code geben, wo Sie den Code ausführen möchten.

Hier möchten Sie einen Anruf tätigen. Fügen Sie den unten angegebenen Code in den Codeblock ein, der für den Aufruf geschrieben wurde.

public void makeCall() 
    { 
     Intent intent = new Intent(Intent.ACTION_CALL); 
     intent.setData(Uri.parse("tel:" + "123456")); 
     int result = ContextCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE); 
     if (result == PackageManager.PERMISSION_GRANTED){ 

      startActivity(intent); 

     } else { 

      requestForCallPermission(); 
     } 
    } 

    private void requestPermission() 
    { 

     if (ActivityCompat.shouldShowRequestPermissionRationale(activity,Manifest.permission.CALL_PHONE)) 
     { 
     } 
     else { 

      ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},PERMISSION_REQUEST_CODE); 
     } 
    } 

    @Override 
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) 
    { 
    switch (requestCode) { 
     case PERMISSION_REQUEST_CODE: 
      if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       makeCall(); 
      } 
      break; 
     } 
    }

  if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
       // TODO: Consider calling 
       // ActivityCompat#requestPermissions 
       // here to request the missing permissions, and then overriding 
       // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
       //           int[] grantResults) 
       // to handle the case where the user grants the permission. See the documentation 
       // for ActivityCompat#requestPermissions for more details. 
       return; 
      } 
Intent intent = new Intent(Intent.ACTION_CALL); 
      intent.setData(Uri.parse("tel:" + "123456")); 
      startActivity(intent);

Versuchen Sie unter Code hoffe, es wird Ihnen helfen. Zuerst werden Sie gefragt, ob Sie ein Popup-Fenster haben, nachdem Sie die Nummer gewählt haben.

if (ContextCompat.checkSelfPermission(HomePanelActivity.this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
      if (ActivityCompat.shouldShowRequestPermissionRationale(HomePanelActivity.this, 
        Manifest.permission.CALL_PHONE)) { 
       ActivityCompat.requestPermissions(HomePanelActivity.this, new String[]{Manifest.permission.CALL_PHONE}, REQUEST_PERMISSION); 
      } 
     } else { 
      Intent callIntent = new Intent(Intent.ACTION_CALL); 
      callIntent.setData(Uri.parse("tel:" + phoneNumber)); 
      if (ActivityCompat.checkSelfPermission(HomePanelActivity.this, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) { 
       startActivity(callIntent); 
      } 
     } 

@Override 
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { 
     switch (requestCode) { 
      case 10: 
       if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
        Intent callIntent = new Intent(Intent.ACTION_CALL); 
        callIntent.setData(Uri.parse("tel:" + phoneNumberToCall)); 
        if (ActivityCompat.checkSelfPermission(HomePanelActivity.this, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) { 
         startActivity(callIntent); 
        } 
       } else { 
        Snackbar.make(drawerLayout, "You Deny permission", Snackbar.LENGTH_SHORT).show(); 
       return; 
      } 
     } 
    };

public void makeCall(String s) 
{ 
    Intent intent = new Intent(Intent.ACTION_CALL); 
    intent.setData(Uri.parse("tel:" + s)); 
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED){ 

     requestForCallPermission(); 

    } else { 
     startActivity(intent); 

    } 
} 
public void requestForCallPermission() 
{ 

    if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.CALL_PHONE)) 
    { 
    } 
    else { 

     ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CALL_PHONE},PERMISSION_REQUEST_CODE); 
    } 
} 

@Override 
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) 
{ 
    switch (requestCode) { 
     case PERMISSION_REQUEST_CODE: 
      if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       makeCall("100"); 
      } 
      break; 
    } 
} 

// Nun rufen die Methode makecall ("your_desire_phone_numder"); makeCall ("100"); Link for more details
