Dialog API

一、按键监听

myMaterDialog.setOnListener(new DialogInterface.OnKeyListener() {
    @Override
    public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
        if(keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount()==0)
        {
            myMaterDialog.dismiss();
            UserBuyActivity.this.finish();
        }
        return false;
    }
});
