How To Display, On Mainactivity, The Number Inserted On A Custom Alertdialogfragment With Edittext?

I'm using a custom alertdialog with an editText to insert a number, the alertdialog is working, but nothing happens when I click positive button, it should display the value insert

Solution 1:

You are not setting listener TestAlertDialogListener in your Activity. Just make below changes and you will get it working.

Create a constructor in your TestAlertDialogFragment which will set the listener for us. I am not pasting the whole code of the dialog, only essential fragments. The onCreateDialog method will be as it was.

publicclassTestAlertDialogFragmentextendsDialogFragment {

// Use this instance of the interface to deliver action events

TestAlertDialogListener mListener;

publicTestAlertDialogFragment(TestAlertDialogListener mListener)
{

    this.mListener=mListener;

}

publicinterfaceTestAlertDialogListener {
    publicvoidonDialogPositiveClick(DialogFragment dialog, int i, String string);

    publicvoidonDialogNegativeClick(DialogFragment dialog);
}

Change your activity code like this:

publicvoidshowTestAlertDialog(View v) {
// Create an instance of the dialog fragment and show itDialogFragmentd=newTestAlertDialogFragment(MainActivity.this);
d.show(getSupportFragmentManager(), "testAlertDialog");
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

}
