android - Blue buble for current location on Google Maps not showing

Question

I am trying to make an app, which will be able to show my current location with a standard blue bubble targeting it. I set my release.keystore, use release.keystore to generate SHA1 fingerprint, and get API key. However, when I start my application, Google Maps is available but not my position, although it appear sometimes. Does anyone have any idea? Thanks a lot.

Answer 1

使用以下代码：

    UiSettings uiSettings = googleMap.getUiSettings();
    uiSettings.setMyLocationButtonEnabled(true);

它将在地图上显示一个按钮，当您单击它时，它将显示您当前的位置，并带有蓝点。

Answer 2

蓝点外观取决于您的设备是否能够自我定位。

确保打开 GPS 并在“设置”应用的“我的位置”部分启用了相关设置：“使用无线网络”和“使用 GPS 卫星”。
