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);

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

return window;

}

}

public class PopupWindowAc extends Activity implements OnClickListener,IRefreshPlayType {

PopupWindow pp;
Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.popupwindow);
  mContext=this;
  initView();

}

private void initView() {
  // TODO Auto-generated method stub
  findViewById(R.id.bt1).setOnClickListener(this);
  findViewById(R.id.bt2).setOnClickListener(this);
  findViewById(R.id.bt3).setOnClickListener(this);
  findViewById(R.id.bt4).setOnClickListener(this);
}

@Override
public void onClick(View v) {
  // TODO Auto-generated method stub
  switch (v.getId()) {
  case R.id.bt1:
   pp=PopupWinBean.makeChangeWindow(mContext);
   pp.showAsDropDown(findViewById(R.id.bt4));

   break;
  case R.id.bt2:
   pp=PopupWinBean.makeWindow(mContext);
   pp.showAtLocation(v, Gravity.TOP, 0, 45);

   break;

  case R.id.bt3:
   pp=PopupWinBean.makeWindow(mContext);
   pp.showAtLocation(v, Gravity.CENTER|Gravity.LEFT, 10, 0);

   break;

  case R.id.bt4:
   pp=PopupWinBean.makeWindow(mContext);
   pp.showAtLocation(v, Gravity.BOTTOM|Gravity.RIGHT, 0, 0);

   break;
  default:
   break;
  }
}

@Override
public void refreshCurrentPlayType(String playStr) {
  // TODO Auto-generated method stub
  ToastUtil.showToast(mContext, playStr);
  pp.dismiss();
}

@Override
public boolean onMenuOpened(int featureId, Menu menu) {
  // TODO Auto-generated method stub

  pp=PopupWinBean.makeChangeWindow(mContext);


  pp.showAsDropDown(findViewById(R.id.bt1), 30, 0);



   return false;   // true--显示系统自带菜单；false--不显示。


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
  // TODO Auto-generated method stub
  menu.add("menu");
  return super.onCreateOptionsMenu(menu);


}

}

//自定义接口

public interface IRefreshPlayType {

public void refreshCurrentPlayType(String playStr);

}
