最近沒事做就寫了一下PopupWindow，希望對有些人有點幫助。
照常先看一下完成后的結果（界面比較難看就不要吐槽了）
點擊地理位置然后彈出的PopupWindow，數據我寫死了但是可以根據你們的需求自己改，或者通過網絡獲取數據。我是通過listView進行展示的你們也可以改成表格布局，具體的實現代碼如下：
PopupWindow的彈出框的整體布局（listView）fragment_popup：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@+id/pop_path" android:layout_width="match_parent" android:layout_height="wrap_content"> </ListView></LinearLayout>
listview要加載的item:pop_list_adapter.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:id="@+id/item_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="18dp"/></LinearLayout>
listview的適配器：PopAdapter
public class PopAdapter extends BaseAdapter { private List<String> list; private Context context; public PopAdapter(List<String> list, Context context) { this.list = list; this.context = context; } @Override public int getCount() { return list.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder viewHolder; if (convertView == null) { viewHolder = new ViewHolder(); convertView = LayoutInflater.from(context).inflate(R.layout.pop_list_adapter, null); viewHolder.item_content = (TextView) convertView.findViewById(R.id.item_content); convertView.setTag(viewHolder); } else { viewHolder = (ViewHolder) convertView.getTag(); } viewHolder.item_content.setText(list.get(position)); return convertView; } private class ViewHolder { private TextView item_content; }}寫一個MyPopupWindow類繼承PopupWindow：
public class MyPopuWindow extends PopupWindow { private View contentView; private ListView lv_pop; private List<String> paths; private Context context; public MyPopuWindow(final Activity context) { this.context = context; //獲得 LayoutInflater 的實例 LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); contentView = inflater.inflate(R.layout.fragment_popup, null); //獲取屏幕的寬高 int h = context.getWindowManager().getDefaultDisplay().getHeight(); int w = context.getWindowManager().getDefaultDisplay().getWidth(); this.setContentView(contentView); // 設置SelectPicPopupWindow彈出窗體的寬 this.setWidth(LayoutParams.MATCH_PARENT); // 設置SelectPicPopupWindow彈出窗體的高 this.setHeight(LayoutParams.WRAP_CONTENT); // 設置SelectPicPopupWindow彈出窗體可點擊 this.setFocusable(true); this.setOutsideTouchable(true); // 刷新狀態 this.update(); // 實例化一個ColorDrawable顏色為半透明 ColorDrawable dw = new ColorDrawable(0000000000); // 點back鍵和其他地方使其消失,設置了這個才能觸發OnDismisslistener ，設置其他控件變化等操作 this.setBackgroundDrawable(dw); // 設置SelectPicPopupWindow彈出窗體動畫效果 this.setAnimationStyle(R.style.AnimationPreview); initData(); } private void initData() { paths = new ArrayList<>(); paths.add("北京"); paths.add("上海"); paths.add("廣州"); paths.add("天津"); paths.add("大連"); paths.add("長春"); paths.add("濟南"); paths.add("青島"); paths.add("無錫"); paths.add("鄭州"); paths.add("寧波"); paths.add("廈門"); lv_pop = (ListView) contentView.findViewById(R.id.pop_path); lv_pop.setAdapter(new PopAdapter(paths, context)); lv_pop.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(context, paths.get(position), Toast.LENGTH_SHORT).show(); showPopupWindow(view); } }); } /** * 顯示popupWindow * * @param parent */ public void showPopupWindow(View parent) { if (!this.isShowing()) { // 以下拉方式顯示popupwindow this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18); } else { this.dismiss(); } }}接下來就是調用PopupWindow顯示了。actionPath：是你的組件也就是我的地理位置
myPopuWindow= new MyPopuWindow(getActivity());myPopuWindow.showPopupWindow(actionPath);
好了大概的一個代碼就是這樣了希望對你們有用。
