PopupWindow的显示位置及简单的响应事件

 



 

这是点击菜单键 弹出的popupView

 

 话不多说，直接上代码吧，部分代码参考了其他blog

 

public class PopupWinBean {

   

 private static String[] info=new String[]{"1","2","3","4","5","6","7","8","10","11","12","13"

                                        ,"111","112","113","14","15","16","7","8","10","11","12","13"};

public static PopupWindow makeChangeWindow(Context context ){

  

  View popupView = LayoutInflater.from(context).

  inflate(R.layout.popup_gridview_change, null);

  GridView gridView = (GridView) popupView.findViewById(R.id.select_grid);

  

  gridView.setAdapter(new PlayChangeAdapter(context, info));

  

  PopupWindow window = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ,true);

  

    //有这句代码  点击PopupWindow外部区域 PopupWindow会自动消失  

  window.setBackgroundDrawable(context.getResources().getDrawable(R.drawable.ic_action_search));

   

  return window;

  

 }

public static PopupWindow makeWindow(final Context context ){

 

 View popupView = LayoutInflater.from(context).

 inflate(R.layout.popup_view_selectplay_item, null);

 

   TextView textView = (TextView) popupView

   .findViewById(R.id.select_text);

   textView.setText("测试popupview显示位置");

  

   textView.setTextColor(context.getResources().getColor(R.color.white));

   textView.setOnClickListener(new View.OnClickListener() {

 

 @Override

 public void onClick(View v) {

  // TODO Auto-generated method stub

  ((IRefreshPlayType)context).refreshCurrentPlayType("测试popupview显示位置");

 }

});

 PopupWindow window = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ,true);

 return window;

 

}
