AlertDialog disappears when touch is outside [Android] [duplicate]

问题

I'm using an Alert Dialog on my application, but it keeps hiding when the users touches outside it. Here is my code:

public class DialogMessageEnd extends DialogFragment
{
    String winner;

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the Builder class for convenient dialog construction
        Snooker_Scoreboard ss = new Snooker_Scoreboard();
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setCancelable(false);
        builder.setMessage(ss.winnerPlayer + " won the match ("+ss.frame1ToPass+"-"+ss.frame2ToPass+")!")
                .setPositiveButton("New Match!", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        Intent i = new Intent(getContext(),PlayerSelection.class);
                        startActivity(i);
                    }
                });



        // Create the AlertDialog object and return it
        return builder.create();
    }

}

As you can see, I used

builder.setCancelable(false);

but it still doesn't solve the probem. Can you help me? thanks

Use setCanceledOnTouchOutside(false) for preventing the dismiss on touching outside of alert dialog.

setCancelable(false) is used for preventing the dismiss on pressing the back button.

    @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the Builder class for convenient dialog construction
    Snooker_Scoreboard ss = new Snooker_Scoreboard();
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setCancelable(false);
    builder.setMessage(ss.winnerPlayer + " won the match ("+ss.frame1ToPass+"-"+ss.frame2ToPass+")!")
            .setPositiveButton("New Match!", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    Intent i = new Intent(getContext(),PlayerSelection.class);
                    startActivity(i);
                }
            });



    // Create the AlertDialog object and return it
    Dialog dialog = builder.create();
    dialog.setCanceledOnTouchOutside(false);         
    return dialog;
}

Add

AlertDialog alertDialog = builder.show();

alertDialog.setCanceledOnTouchOutside(false);

in your code

回答3:

You can override the default function for the Dialogue and assure nothing happens. Should work fine.

@Override
public boolean onTouchEvent(MotionEvent event) {
    // If we've received a touch notification that the user has touched
    // outside the app, finish the activity.
    if (MotionEvent.ACTION_OUTSIDE == event.getAction()) {
    // Do Something or not...
        return true;
    }
    return false;
}

Or for better practice:

builder.setCanceledOnTouchOutside(false)
