Question

I have an AlertDialog without buttons. How do I dismiss the dialog when clicking on it?

Answer 1

what I can think about this problem is to set your own view to that dialog, and then you can set a onClickListener to that view, so you can deal with the click event.
Below is my code:

@Override
protected Dialog onCreateDialog(int id, Bundle args) {
    AlertDialog.Builder builder=new Builder(this);
    builder.setTitle("title");

    LayoutInflater inflater=(LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view=inflater.inflate(R.layout.firstview, null);//inflate your own view
    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            YourActivity.this.dismissDialog(dialog_ID);//dismiss the dialog
        }
    });

    builder.setView(view);//set your custom view to your dialog

    return builder.create();
}
