popupWindow的用法（1）

可以参考下这个http://www.jcodecraeer.com/a/anzhuokaifa/androidkaifa/2014/0702/1627.html讲的挺好

我这里主要实现的是那种类似两个listView并在一起的那种

case R.id.tv_school:            doschool();break;     //驾校case R.id.tv_region:            doregion();

                        break;    //地区

private void doregion() {tv_region.setTextColor(getResources().getColor(R.color.discount_tab));tv_school.setTextColor(getResources().getColor(R.color.black));iv_cursor1.setVisibility(View.INVISIBLE);iv_cursor2.setVisibility(View.VISIBLE);                            //这个是上面tab的变化if (pop!= null && pop.isShowing()) {              pop.dismiss();                                                         //当popupWindow存在时，在按他上面的会先取消popupWindow        } else {          schoolSel = -1;        areaSel = -1;                                                      //分别是左右两个listView选择的position                                                                       /***    弹出自定义的菜单        ***/      View layout = getLayoutInflater().inflate(R.layout.drivingschool_school,null);     //这个布局下面有            lv_school=(ListView) layout.findViewById(R.id.lv_region);            lv_area=(ListView) layout.findViewById(R.id.lv_school);                        DrivingSchoolNameAdapter schoolAdapter=new DrivingSchoolNameAdapter(this, getAdapterFromNameArea(cateAreaist));//为右边的listView设置adapter            lv_area.setAdapter(schoolAdapter);            lv_area.setOnItemClickListener(itemAreaSchoolClickListener);                                                   //右边项的点击事件            pop = new PopupWindow(layout,WorkApplication.getInstance().getScreenWidth(),WorkApplication.getInstance().getScreenHeight());  宽高设置                                    ColorDrawable cd = new ColorDrawable(getResources().getColor(R.color.main_white));              pop.setBackgroundDrawable(cd);  //颜色设置,应该只包含左边没有被点击的地方            pop.update();              pop.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);              pop.setTouchable(true);           // 设置popupwindow可点击              pop.setOutsideTouchable(true);    // 设置popupwindow外部可点击              pop.setFocusable(true);           //获取焦点                          pop.showAsDropDown(tv_school,5,5);    //相对某控件的位置            pop.setTouchInterceptor(new View.OnTouchListener() {                  @Override                  public boolean onTouch(View v, MotionEvent event) {                      if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {                          pop.dismiss();                                             //当点击pop以外的位置，pop不为空的话会先使pop为空                        return true;                       }                      return false;                  }              });                          if(cateAreaist == null){            HashMap<String , Object> map = new HashMap<String , Object>();            map.put("type", 1);            Task task = new Task(TaskType.TS_GET_AREA_SCHOOL_LIST, map);       //这段是连接服务器的，不用管            MainService.newTask(task);            ProgressDialogUtil.showMsgDialog(this);            }        }}private List<String> getAdapterFromNameArea(List<DSNameAreaInfo> obj){if(obj == null){return null;}List<String> arr = new ArrayList<String>();for (DSNameAreaInfo item : obj) {arr.add(item.getName());}return arr;}

这里这列举其中一种，另外一种是一样的。

private  OnItemClickListener itemAreaSchoolClickListener=new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {switch (parent.getId()) {case R.id.lv_school:schoolSel = -1;areaSel = position;       //点击左边项DrivingSchoolNameAdapter dsschoolNameAdapter=new DrivingSchoolNameAdapter(DrivingschoolSchoolAreaActivity.this, cateAreaist.get(position).getAreas());            lv_school.setAdapter(dsschoolNameAdapter);            lv_school.setOnItemClickListener(itemAreaSchoolClickListener);break;case R.id.lv_region:               //点击右边项schoollistPage = 1;schoollist.clear();dsschoolAdapter.notifyDataSetChanged();schoolSel = position;pop.dismiss();loadschool(true, false);break;default:break;}}};<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="horizontal"     >    <ListView         android:id="@+id/lv_school"        android:layout_height="fill_parent"        android:layout_width="0dip"        android:layout_weight="1"        android:listSelector="@color/gainsboro"         ></ListView>     <ListView         android:id="@+id/lv_region"        android:layout_height="fill_parent"        android:layout_width="0dip"        android:layout_weight="1"        android:listSelector="@android:color/white"         android:background="@color/gainsboro"        ></ListView></LinearLayout>
