我有3个按钮，我正在使用mapactivity。只有第一个按钮响应，然后第二个按钮按时间顺序响应。我已经在这些按钮中存储了标记，所以我希望它们在我点击其中任何一个时单独响应
这是我的.java文件

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
final Button button1 = (Button) findViewById(R.id.buttonMaps);
final Button button2 = (Button)findViewById(R.id.buttonMaps2);
final Button button3 = (Button)findViewById(R.id.buttonMaps3);
@Override
protected void onCreate(Bundle savedinstancestate) {
super.onCreate(savedinstancestate);
setContentView(R.layout.activity_maps);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mMap.clear();
if (button1.isShown()) {
mMap.addMarker(new MarkerOptions().position(new LatLng(, )).title("").snippet("My Location").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher)));
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mMap.clear();
if (button2.isShown()) {
mMap.addMarker(new MarkerOptions().position(new LatLng()).title("").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher_hospital)));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(), ));
button3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mMap.clear();
if (button3.isShown()) {
mMap.addMarker(new MarkerOptions().position(new LatLng(`enter code here`)).title(" ").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher_busstop)));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(), ));
}
}
});
}
}
});
}
}
});
}
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.

@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng ( ),));
}
}

答案 0 :(得分：0)
您正在其他onclicklisteners中设置onclicklisteners。在您的实现中，当单击button1时，设置onclicklistener为button2，当单击按钮2时（在button1单击之后），设置on3licklistnere for button3。直接在oncreate中设置所有3个onclicklistener。

只有按下按钮1才能定义按钮2-3按下。需要单独识别。
