Question

I have a problem with a custom dialog.
My dialog consists of a TextView, EditText and an “Ok” Button. After clicking “Ok”, it should get the text from EditText field and assign it to the String variable “name” defined in the Activity.
Everything seems to work, no errors etc, however “text” is always an empty String.
I read some topics about such problems, however I’m not really sure what adjustments I should make here.
I’m quite new to Android programming, so I’d be grateful if somebody could explain the problem to me. Thanks in advance.

     final Dialog dialog = new Dialog(MyActivity.this);
     dialog.setContentView(R.layout.custom_dialog);
     dialog.setTitle("Title");

     final View layout = View.inflate(this, R.layout.custom_dialog, null);
     Button button = (Button) dialog.findViewById(R.id.dialog_ok);
     button.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {
                EditText edit=(EditText)layout.findViewById(R.id.dialog_edit);
                String text=edit.getText().toString();

                name=text;

                dialog.dismiss();
         }
     });   

     dialog.show();

You are inflating a layout where it is not needed. I fixed your code as you see I removed your line where it inflates and changed the line where you try to find the EditText view.

final Dialog dialog = new Dialog(MyActivity.this);
 dialog.setContentView(R.layout.custom_dialog);
 dialog.setTitle("Title");

 Button button = (Button) dialog.findViewById(R.id.dialog_ok);
 button.setOnClickListener(new OnClickListener() {
     public void onClick(View v) {

            EditText edit=(EditText)dialog.findViewById(R.id.dialog_edit);
            String text=edit.getText().toString();

            dialog.dismiss();
            name=text;

     }
 });   


dialog.show();
