Android自定义视图对话框关闭

Question

1. 列表项

请帮助!!我正在创造一个简单的游戏。 为此，我创建了一个自定义视图。

public class GameView extends View

我有一个打开游戏设置的按钮。所以我为此创建了一个对话框。 按下对话框按钮后，我在自定义视图中重新绘制。但它并不是立即令人耳目一新的观点。这需要几秒钟。

enter code here
public void settingFunction()
{
    int musicOn=-1; int suitLevel = -1;
    final Dialog endDialog = new Dialog(mycontext);
    endDialog.setCancelable(false);
    endDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    endDialog.setContentView(R.layout.settings);
    TextView settingText = (TextView) endDialog.findViewById(R.id.textLayout);
    TextView settingText1 = (TextView) endDialog.findViewById(R.id.textLayout_1);
    Button nextButton = (Button) endDialog.findViewById(R.id.nextHandButton);
    final Switch sw1 = (Switch) endDialog.findViewById(R.id.switch1);

    RadioButton easy = (RadioButton) endDialog.findViewById(R.id.easy);
    RadioButton medium = (RadioButton) endDialog.findViewById(R.id.medium);
    RadioButton hard = (RadioButton) endDialog.findViewById(R.id.difficult);
    //dbC.insertSetting("MUSIC",1);
    String st = "MUSIC";
    musicOn =dbC.readSetting( st);
    suitLevel =dbC.readSetting( "SUIT");
     int ct ;
    //sw1.setChecked(true);
    //Toast.makeText(mycontext," music" + musicOn ,Toast.LENGTH_SHORT).show();
    if(musicOn ==1)
    {
        sw1.setChecked(true);
    } else {sw1.setChecked(false);}

    if(suitLevel ==1)
    {
        easy.setChecked(true);
    } else if (suitLevel ==2)
    {medium.setChecked(true);} else if (suitLevel==3) {easy.setChecked(true);}

    endDialog.show();

    sw1.setOnCheckedChangeListener(
            new CompoundButton.OnCheckedChangeListener()
            {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
                {
                    if(isChecked)
                    {dbC.updateSetting("MUSIC",1);
                    }
                    else {dbC.updateSetting("MUSIC",0);}
                }
            }
    );
    nextButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            initalAnimation = 1;
            endDialog.dismiss();
            invalidate();
            //alertUser();
        }
    });
}
