How can can I add custom buttons into an AlertDialog's layout?

Question

I have AlertDialog with Positive and Negative buttons. In AlertDialog layout I have EditText and two Buttons (btnAdd1, btnAdd2). I want when user click at the Button btnAdd1 or btnAdd2 add same text to EditText in AlertDialog (but no close AlertDialog). Is this possible do in AlertDialog or I have to use only Dialog?

This is layout (R.layout.prompt) of AlertDialog:

<LinearLayout> <EditText     android:id="@+id/userInput"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:inputType="text" >      <requestFocus /> </EditText>  <Button     android:id="@+id/btnAdd1"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="bla" />  <Button     android:id="@+id/btnAdd2"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="bla" />    </LinearLayout> 

And this is source code:

    LayoutInflater layoutInflater = LayoutInflater.from(this);         View promptView = layoutInflater.inflate(R.layout.prompt, null);      AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);     alertDialogBuilder.setView(promptView);     alertDialogBuilder             .setCancelable(false)             .setPositiveButton("OK", new DialogInterface.OnClickListener() {                 public void onClick(DialogInterface dialog, int id) {                               //...                  }             })             .setNegativeButton("Cancel",                     new DialogInterface.OnClickListener() {                         public void onClick(DialogInterface dialog, int id) {                             dialog.cancel();                         }                     });      AlertDialog alertD = alertDialogBuilder.create();     alertD.show(); 

I want get acces to the btnAdd1 and btnAdd2 from the layout. Set the OnClickListener() to these two buttons.

Answer 1

The following code will inflate a view from R.layout.prompt and set it to the AlertDialog. The positive and negative buttons will not be used. You can set the onClick behaviors for btnAdd1 and btnAdd2:

LayoutInflater layoutInflater = LayoutInflater.from(this); View promptView = layoutInflater.inflate(R.layout.prompt, null);  final AlertDialog alertD = new AlertDialog.Builder(this).create();  EditText userInput = (EditText) promptView.findViewById(R.id.userInput);  Button btnAdd1 = (Button) promptView.findViewById(R.id.btnAdd1);  Button btnAdd2 = (Button) promptView.findViewById(R.id.btnAdd2);  btnAdd1.setOnClickListener(new OnClickListener() {     public void onClick(View v) {          // btnAdd1 has been clicked      } });  btnAdd2.setOnClickListener(new OnClickListener() {     public void onClick(View v) {          // btnAdd2 has been clicked      } });  alertD.setView(promptView);  alertD.show(); 

Answer 2

what you want to do is;

alertD.show(); Button button = (Button)promptView.findViewById(R.id.buttonId); button.setOnClickListener(....) 

using the view to call findViewById, rather than the activity, which will look for the id in the layout that is being displayed.
