java 代码实现popup menu的类

public class PopMenu {
private ArrayList<String> itemList;
private Context context;
private PopupWindow popupWindow ;
private ListView mLv; @SuppressWarnings("deprecation")
public PopMenu(Context context) {
this.context = context;
View view = LayoutInflater.from(context).inflate(R.layout.listview_popup_menu, null);
itemList = new ArrayList<String>();
//璁剧疆 listview
mLv = (ListView)view.findViewById(R.id.lv); mLv.setAdapter(new PopAdapter());
popupWindow = new PopupWindow(view, 200, LayoutParams.WRAP_CONTENT);
popupWindow = new PopupWindow(view, context.getResources().getDimensionPixelSize(R.dimen.popmenu_width), LayoutParams.WRAP_CONTENT);
popupWindow.setBackgroundDrawable(new BitmapDrawable()); } //璁剧疆鑿滃崟椤圭偣鍑荤洃鍚櫒
public void setOnItemClickListener(android.widget.AdapterView.OnItemClickListener listener) {
mLv.setOnItemClickListener(listener);
} //鎵归噺娣诲姞鑿滃崟椤?
public void addItems(String[] items) {
for (String s : items)
itemList.add(s);

让popup menu在适当地方展示出来的方法

mHospitalPopMenu = new PopMenu(mContext);
mHospitalPopMenu.addItems(mHospitalArrList);
mHospitalPopMenu.setOnItemClickListener(new OnItemClickListener() { @Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView tvItem = (TextView)view.findViewById(R.id.tvItem);
mTvHospital.setText(tvItem.getText());
mHospitalPopMenu.dismiss();
}
});
mHospitalArrList = new ArrayList<String>();
String s[] = new String[]{"鍗庤タ鍖婚櫌","鎴愰兘鍐涘尯鍖婚櫌","鍥涘窛楠ㄧ鍖婚櫌"};
for (String s1: s){
mHospitalArrList.add(s1);
}
mCityPopMenu.showAsDropDown(mTvCity); //在mTvCity控件下show 弹出菜单
