点击menu实现弹出popWindow的功能并不是很复杂，但是容易出现的问题是popWindow中的组件的监听事件和menu按钮的监听事件发生冲突
点击menu菜单键弹出popWindow之后再次点击menu菜单键popWindow无法消失，或者点击popWindow中的组件比如listView监听事件无法响应
最近一直被这个问题困扰 ，在查过众多资料后，今天终于将这个问题解决了
贴出代码
private PopupWindow menu;
private LayoutInflater inflater;
private View layout;
private ListView popmenulist;
private SimpleAdapter simpleAdapter;
private int icon[] = new int[] { R.drawable.menu_search,R.drawable.menu_add};
private String content[] = new String[] { "搜索联系人", "添加联系人" };
private List<Map<String, Object>> datalist = new ArrayList<Map<String, Object>>();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initMenu();
}
// 获得后退键退出
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0&&!menu.isShowing()) {
MainService.promptExit(BoxinContactsActivity.this);
}
if(keyCode == KeyEvent.KEYCODE_MENU&&!menu.isShowing()&&event.getRepeatCount() == 0){
show();
}
//return super.onKeyDown(keyCode, event);
return true;
}
private void show(){
if(!menu.isShowing()){
// menu.setOutsideTouchable(true);
menu.setFocusable(true);
// menu.update();
menu.showAtLocation(this.findViewById(R.id.linearLayout1), Gravity.BOTTOM|Gravity.CENTER_VERTICAL,0,0);
}
//初始化popWindow
private void initMenu(){
if(menu==null||layout==null){
inflater = (LayoutInflater) this.getSystemService(LAYOUT_INFLATER_SERVICE);
layout = inflater.inflate(R.layout.menu,null);
//解决问题的关键代码：对popWindow的布局进行按键的监听
layout.setFocusableInTouchMode(true);
layout.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_BACK&&menu.isShowing()&&event.getAction()==event.ACTION_DOWN){
menu.dismiss();
return true;
}
if(keyCode == KeyEvent.KEYCODE_MENU&&menu.isShowing()&&event.getAction()==event.ACTION_DOWN){
menu.dismiss();
return true;
}
return false;
}
});
menu = new PopupWindow(layout, WindowManager.LayoutParams.FILL_PARENT,WindowManager.LayoutParams.FILL_PARENT);
popmenulist=(ListView) layout.findViewById(R.id.popmenulist);
for(int i=0;i<content.length;i++){
Map<String, Object> map = new HashMap<String, Object>();
map.put("icon", icon[i]);
map.put("content", content[i]);
datalist.add(map);
}
simpleAdapter=new SimpleAdapter(BoxinContactsActivity.this, datalist, R.layout.menuinfo, new String[]{"icon","content"}, new int[]{R.id.menuicon,R.id.menutext});
popmenulist.setAdapter(simpleAdapter);
// popmenulist.setFocusable(true);
// popmenulist.setFocusableInTouchMode(true);
// popmenulist.setItemsCanFocus(false);
popmenulist.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
if(position==0){
Intent intent=new Intent(ContactsActivity.this,mainSearchActivity.class);
ContactsActivity.this.startActivity(intent);
menu.dismiss();
}else{
Intent intent=new Intent(ContactsActivity.this,AddActivity.class);
ContactsActivity.this.startActivity(intent);
menu.dismiss();
}
}
});
}
// menu.update();
}
效果图：
