我在navdraw中有一个按钮Submit_house，它在另一个按钮的（add_house）onclick侦听器中获取一个onclick侦听器。 Submit_house是结束add_house的onclick的按钮，此后它将获得新的onclick。但是由于某种原因，第一个Submit_house onclick无法正常工作（那里的log命令实际上没有注册）。为什么呢？
main.java中的代码：
building_onclick = new View.OnClickListener() {
@Override
public void onClick(final View v) {
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng point) {
mMap.setOnMapClickListener(null);
// this line clears the arraylist
arrayList.clear();
// next thing you have to do is check if your adapter has changed
adapter.notifyDataSetChanged();
building.emptyBuilding();
//the navdraw
buildingViewNavdraw(add_house, houseList);
//launches drawer
// locks drawer from opening from swipes
navDrawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
// If the navigation drawer is not open then open it, if its already open then close it.
if(!navDrawer.isDrawerOpen(Gravity.RIGHT)) navDrawer.openDrawer(Gravity.RIGHT);
else navDrawer.closeDrawer(Gravity.LEFT);
//sets building latlng
building.setLat(point.latitude);
building.setLng(point.longitude);
building.setMarkerId(Double.toString(building.getLat()).replace(".","") + Double.toString(building.getLng()).replace(".",""));
View.OnClickListener add_houseOnClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
//TODO: create alert dialog to get apartment number
house.setApartment("1");
houseEditNavdraw(status, activists, familyNameEdit, addressEdit, descriptionEdit, currentStatusEdit, submit_house, add_report);
isHouseUploaded = false;
isInBuilding = true;
house.setType("House");
//copies over content from building to house
house.setLat(building.getLat());
house.setLng(building.getLng());
house.setMarkerId("A" + house.getApartment() + building.getMarkerId());
house.setLocation(building.getLocation());
currentStatusEdit.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
if (currentStatusEdit.getSelectedItem().toString().equals("קשר המשך")){
currentActivistsEdit.setVisibility(View.VISIBLE);

答案 0 :(得分：0)
Implement your activity with View.OnClickListener interface.
It will implement a method with name onClick().
Now add this line in onCreate() method : submit_house.setOnClickListener(this);
And you can perform your work in onClick() as
public void onClick(View v)
{
if(v.id==R.id.submit_house)
{
//
}
}
But you cannot perform two different functions on a single button. For that
you have to use internal variable to identify the case.
