GoogleApiClient不會通過onChangedLocation方法刷新我的位置

Question

我想通過刷新位置來更新代碼。 目前我一個代碼：

    mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(10 * 1000)        // 10 seconds, in milliseconds
            .setFastestInterval(1 * 1000); // 1 second, in milliseconds

但是我很確定它不會刷新我的位置。 我以為在應用運行的情況下駕駛汽車，而我的位置沒有改變。 請告訴我我應該解決什么以改善它？ 我了解它跟隨我的位置的事情是，每當我更改位置並走出地圖時，地圖就會跟隨我。

還請告訴我是否有可能創建一種圖標來顯示我當前的位置（ 不是標記 -這就是我現在擁有的圖標）。

您可以使用融合的位置服務獲取位置更新。 進行后台服務並在每個特定間隔獲取位置。在這里查看我的答案https://stackoverflow.com/a/43602323/3789993
