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() {

@Override
public 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"?>
