Answer 1

You can use your dialog_layout to retrieve your Buttons as you did with your EditText

Button okBtn= (Button) dialog_layout.findViewById(R.id.btn_ok);
Button cancelBtn = (Button) dialog_layout.findViewById(R.id.btn_cancel);

then set you onClickListeners

okBtn.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(View v)
    {
        // some code
    }
});
cancelBtn.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(View v)
    {
        // some code
    }
});

XML Code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

      <Button
          android:id="@+id/dialogButtonCancell"
          android:layout_width="75dp"
          android:layout_height="75dp">

      <Button
          android:id="@+id/dialogButtonOK"
          android:layout_width="80dp"
          android:layout_height="70dp"/>

</RelativeLayout>

Java Code:

// custom dialog
final Dialog dialog = new Dialog(context);
//name of xml - custom
dialog.setContentView(R.layout.custom);

// set the custom dialog components - text, image and button
Button dialogButtonOK = (Button) dialog.findViewById(R.id.dialogButtonOK);
Button dialogButtonCancell = (Button) dialog.findViewById(R.id.dialogButtonCancell);

  dialog.setTitle("Warning!!!!!");

// if button is clicked, call some method..
dialogButtonOk.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
    someMethod();
    }
});

dialogButtonCancell.setOnClickListener(new OnClickListener() {
   public void onClick(View v) {                            
   dialog.dismiss();                        
   }
});
dialog.show();
