handle button clicks in a DialogFragment
Do along these lines
Dialog dl = mDialogFragment.getDialog();
Button btn = dl.findViewById(R.id.btn);
btn.setOnClickListener(this);
This is the code for a Dialog I'm using (the actual GUI for the dialog is defined in the layout resource confirm_dialog.xml):
public class ConfirmDialog extends DialogFragment {
public static String TAG = "Confirm Dialog";
public interface ConfirmDialogCompliant {
public void doOkConfirmClick();
public void doCancelConfirmClick();
}
private ConfirmDialogCompliant caller;
private String message;
public ConfirmDialog(ConfirmDialogCompliant caller, String message){
super();
this.caller = caller;
this.message = message;
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.confirm_dialog, container, false);
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
((TextView) view.findViewById(R.id.textview_confirm)).setText(message);
((Button) view.findViewById(R.id.ok_confirm_button)).setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
caller.doOkConfirmClick();
}
});
((Button) view.findViewById(R.id.cancel_confirm_button)).setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
caller.doCancelConfirmClick();
}
});
return view;
}
}
The dialog is created with the following lines
confirm_dialog = new ConfirmDialog(this, message);
confirm_dialog.show(getActivity().getSupportFragmentManager(), ConfirmDialog.TAG);
The interface definition is used to assure that the caller (Fragment or Activity) implements the methods to handle the events thrown by the controller. That is, a Fragment or Activity calling this dialog must implement the given interface.
Maybe there is a better solution but this is the one I figured out. Hope it helps!
here is an example to handel a cancel button click on a dialog from the FragmentDialog class:
i used android.support.v4.app.DialogFragment;
public class MyDialogFragment extends DialogFragment {
public MyDialogFragment(){}
public static String TAG = "info Dialog";
Button btn;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.info_layout, container);
getDialog().requestWindowFeature(STYLE_NO_TITLE);
btn=(Button)view.findViewById(R.id.close_dialog_btn_info_layout);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
getDialog().dismiss();
}
});
return view;
}
}
