Wie kann die alertDialogbox beim Klicken auf die Schaltfläche verschwinden?

Question

Ich möchte nur die alertDialog-Box verschwinden, wenn Benutzer die "Fertig" -Taste auf der Tastatur drücken. Ich versuche, die Methode "disney()" zu verwenden, aber es besagt, dass "alles11", das mein AlertDialog-Objekt ist, nicht aufgelöst werden kann.

MainActivity.java

public class MainActivity extends AppCompatActivity { 

    static final int REQUEST_IMAGE_CAPTURE = 1; 
    ImageView imageView; 

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

     Button PicButton = (Button)findViewById(R.id.picButton_ID); 
     imageView = (ImageView)findViewById(R.id.imageView_ID); 
     Button topTextButton = (Button)findViewById(R.id.topButton_ID); 
     Button bottonTextButton = (Button)findViewById(R.id.bottomButton_ID); 
     final TextView topText = (TextView)findViewById(R.id.topText_ID); 
     TextView bottomText = (TextView)findViewById(R.id.bottomText_ID); 

     //Disables button if user has no camera 
     if(!hasCamera()) { 
      PicButton.setEnabled(false); 
     } 

     final AlertDialog.Builder builder1 = new AlertDialog.Builder(this); 



     topTextButton.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View view) { 



       builder1.setMessage("Write your zinger here."); 
       builder1.setCancelable(true); 

       final EditText input = new EditText(MainActivity.this); 
       builder1.setView(input); 
       input.setInputType(InputType.TYPE_CLASS_TEXT); 
       input.setImeOptions(EditorInfo.IME_ACTION_DONE); 

       //checks if "Done" button on soft keyboard is clicked 
       input.setOnEditorActionListener(new TextView.OnEditorActionListener() {

         if(actionId==EditorInfo.IME_ACTION_DONE){ 
          //what happens when "Done" is clicked 
          topText.setText(input.getText().toString()); 
          alert11.dismiss(); 


         } 
         return false; 

        } 

       }); 



       AlertDialog alert11 = builder1.create(); 
       alert11.show(); 

      } 

     }); 

    } 

    //checks if user has a camera 
    private boolean hasCamera(){ 
     return getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY); 
    } 

    //Launcing the camera 
    public void launchCamera(View view){ 
     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     //take a picture and pass results along to onAcivityResult 
     startActivityForResult(intent, REQUEST_IMAGE_CAPTURE); 
    } 

    //if you want to return the image taken 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
      if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK){ 
       //get the photo 
       Bundle extras = data.getExtras(); 
       Bitmap photo = (Bitmap)extras.get("data"); 
       imageView.setImageBitmap(photo); 
      } 
    } 
}
