I am busy creating an application in Android Studio that uses Maps API.
I have successfully created OnInfoWindowClickListener to my Google Map. I have 2 different markers I set on my Google Map, but I want to set thousands of markers eventually.
When a user clicks on the Info Window, it must open a new activity.
So example, if a user clicks on 'Marker A', then 'Activity A' must open. Or if a user clicks on 'Marker B', then 'Activity B' must open. Or if a user clicks on 'Marker C', then 'Activity C' must open.
I have attempted to use the 'if statement & else if statement' in my code, but when I click on the Marker's Info Window, nothing happens?
我正忙着在Android Studio中创建一个使用Maps API的应用程序。我已成功为我的Google Map创建了OnInfoWindowClickListener。我在Google地图上设置了2个不同的标记,但我想最终设置数千个标记。当用户单击“信息窗口”时,它必须打开一个新活动。例如,如果用户点击“标记A”,则必须打开“活动A”。或者,如果用户点击“标记B”,则必须打开“活动B”。或者,如果用户点击“标记C”,则必须打开“活动C”。我试图在我的代码中使用'if statement&else if语句',但是当我点击Marker的Info Window时,没有任何反应?

you are checking like this in your if clause:
你在if子句中这样检查:
if (googleMap.equals("Durban")) {
Intent intent = new Intent(MainActivity.this, Durban.class);
startActivity(intent);
}
but you should check on the marker of the public void onInfoWindowClick(Marker marker)
method.
但你应该检查public void onInfoWindowClick(Marker marker)方法的标记。
do something like this:
做这样的事情:
if (marker.getTitle().equals("Durban")) {
Intent intent = new Intent(MainActivity.this, Durban.class);
startActivity(intent);
}
