您好，我有疑问如何在点击标记时实现信息窗口？
问题是我在地图上有很多标记，如果单击信息窗口，每个标记都有另一个活动。enter code here
这个例子
我尝试了很多代码但没有解决
Intent intent = new Intent(ThisActivity.this,OneActivity.class);
startActivity(intent);
}
});

标签： android android-activity marker infowindow
这是完美的工作：
mapview.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
@Override
public void onInfoWindowClick(Marker marker) {
if(marker==marler1){
Intent intent = new Intent(MapActivity.this,Activity1.class);
startActivity(intent);
}else(marker==marler2){
Intent intent = new Intent(MapActivity.this,Activity2.class);
startActivity(intent);
}
}
});

首先：尝试更多地寻找解决方案。
提示：（伪代码）
Marker m1 = map.addMarker(bla bla);
Marker m2 = map.addMarker(bla bla);
onMarkerClicked(Marker m) {
if(m == m1) {
//do what you want to do for marker one
}
else if(m == m2) {
//do what you want to do for marker two
}
}
【讨论】：
onMarkerClick 或onInfoWindowClick，您可以检查if(m == m1) 或if(m==m2)
好主意是设置标记标题，然后在侦听器中根据标题执行操作
marker.getTitle()

这是我的代码。
首先在build.gradle中添加依赖。

compile 'com.google.android.gms:play-services-location:8.1.0'
compile 'com.google.android.gms:play-services-maps:8.4.0'
