采用popwindow实现无黑边弹窗
代码：
public class ExitGameDialog{        Context context;    RelativeLayout contentViewbg;    RelativeLayout contentView;    RelativeLayout.LayoutParams content_parms;    android.view.ViewGroup.LayoutParams  alert_layout_parms;    String orgen="#fe9d00";    String green="#5ec324";    PopupWindow  pop;    public ExitGameDialog(Context context,ExitGameCallBack mBack1)    {            //super(context);            this.context = context;             this.mBack=mBack1;           WindowManager manager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);      int screenwidth = manager.getDefaultDisplay().getWidth();      int screenHeight = manager.getDefaultDisplay().getHeight();      int leftAndRight=DisplayUtil.dip2px(context,25);                      //xml中布局直接View view = inflater.inflate(R.layout.test_alertdialog_listview,null);引入即可      //<!------------------------代码设置布局，xml布局可以直接跳过换用inflate引入------------------------------->      //全屏透明背景      contentViewbg=new RelativeLayout(context);          alert_layout_parms=new LayoutParams(android.view.ViewGroup.LayoutParams.MATCH_PARENT,android.view.ViewGroup.LayoutParams.MATCH_PARENT);          contentViewbg.setBackgroundColor(Color.parseColor("#ba000000"));          contentViewbg.setGravity(Gravity.CENTER);                    contentView=new RelativeLayout(context);          content_parms=new RelativeLayout.LayoutParams(screenwidth-2*leftAndRight,RelativeLayout.LayoutParams.WRAP_CONTENT);          contentView.setBackgroundColor(Color.WHITE);          contentView.setGravity(Gravity.CENTER);          contentView.setPadding(leftAndRight,leftAndRight,leftAndRight,leftAndRight);                    LinearLayout content_layout=new LinearLayout(context);
