基于上一篇实现的SimpleListPopupWindow<T>

这次是个简单的PopupWindow，快速迭代用。

import java.util.List;import android.content.Context;import android.view.View;import android.widget.AdapterView;import android.widget.LinearLayout.LayoutParams;import android.widget.ListView;import android.widget.PopupWindow;import com.mb.bgfitting.App;import com.mb.bgfitting.CommonAdapter;import com.mb.bgfitting.ViewHolder;import com.mb.bgfitting.app.R;/** *  * @author pythoner *  */public class SimpleListPopupWindow<T> extends PopupWindow {private Context context;private CommonAdapter<T> adapter;private List<T> beans;public SimpleListPopupWindow(Context context, View view, int width,List<T> b) {super(view, width, LayoutParams.WRAP_CONTENT, true);this.context = context;this.beans = b;this.setBackgroundDrawable(App.res.getDrawable(R.drawable.bg_popupwindow));this.setOutsideTouchable(true);this.setAnimationStyle(android.R.style.Animation_Dialog);// this.update();// this.setTouchable(true);// this.setFocusable(false);ListView listView = (ListView) view.findViewById(R.id.listView);listView.setAdapter(adapter = new CommonAdapter<T>(context, beans,R.layout.item_for_popupwindow_simple) {@Overridepublic void setValues(ViewHolder helper, T item, int position) {helper.setText(R.id.item_0, item.toString());}});listView.setOnItemClickListener(new ListView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> pearnt, View view,int position, long id) {// TODO Auto-generated method stubdismiss();if (onItemClickListener != null) {onItemClickListener.onItemClick(position,beans.get(position));}}});}public interface OnItemClickListener<T> {void onItemClick(int position, T item);}OnItemClickListener<T> onItemClickListener;public void setOnItemClickListener(OnItemClickListener<T> onItemClickListener) {this.onItemClickListener = onItemClickListener;}}

一个简单的Item：item_for_popupwindow_simple.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="wrap_content">    <TextView         android:id="@+id/item_0"        android:layout_width="match_parent"android:layout_height="wrap_content"android:paddingTop="8dp"android:paddingBottom="8dp"android:gravity="center"android:textColor="@color/base_text_black"android:textSize="@dimen/font_middle"android:singleLine="true"        /></RelativeLayout>

用法：

private void showPopWindow(List<String> list) {View view = LayoutInflater.from(context).inflate(R.layout.popupwindow_simple, null);final SimpleListPopupWindow<String> popupWindow = new SimpleListPopupWindow<String>(context,view, btn_appointmentIndex.getWidth(), list);popupWindow.showAsDropDown(btn_appointmentIndex, 0, 0);popupWindow.setOnItemClickListener(new SimpleListPopupWindow.OnItemClickListener<String>() {@Overridepublic void onItemClick(int position,final String item) {// TODO Auto-generated method stub}});}

popupwindow_simple.xml:

<?xml version="1.0" encoding="utf-8"?><ListView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/listView"    android:layout_width="match_parent"android:layout_height="wrap_content"android:cacheColorHint="@android:color/transparent"android:listSelector="@color/base_gray"    />
