Question

我有这样的代码，我希望它显示当前位置的街道名称。我尝试了很多搜索，但找不到任何有用的信息。我是新手android开发者，有人可以帮我创建吗？

        // The connection has been interrupted.
        // Disable any UI components that depend on Google APIs
        // until onConnected() is called.
    }

    @Override

        // This callback is important for handling errors that
        // may occur while attempting to connect with Google.
        //
        // More about this in the 'Handle Connection Failures' section.

    }

    @Override
    protected void onStart() {
        super.onStart();
        // Connect the client.
        mGoogleApiClient.connect();
    }

    @Override
    protected void onStop() {
        // Disconnecting the client invalidates it.
        mGoogleApiClient.disconnect();
        super.onStop();
    }

}

Answer 1

mCurrentLocation只是一个纬度/经度坐标集。

您需要通过＆＃34;反向地理编码＆＃34;。

转换这些坐标

请参阅Google的此文档（＆＃34;显示位置地址＆＃34;）： https://developer.android.com/training/location/display-address.html

Location为您提供的内容：http://developer.android.com/reference/android/location/Location.html
