只有一个 onClick 监听器响应初始启动 android studio

Question

我有 3 个按钮，我正在使用 mapsactivity。只有第一个按钮响应，然后是第二个，按时间顺序。我在这些按钮中存储了标记，因此我希望它们在我点击其中任何一个时独立响应

这是我的 .java 文件

Answer 1

你定义按钮2-3只有在你按下按钮1时才按下。需要单独识别。

    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(), ));
            }
        }
    });

Answer 2

您正在其他 onclicklisteners 中设置 onclicklisteners。在您的实现中，当单击按钮 1 时，设置按钮 2 的 onclicklistener，当单击按钮 2 时（单击按钮 1 后），设置按钮 3 的 onclicklistnere。直接在 oncreate 中设置所有 3 个 onclicklistener。
