Android LocationClient类已弃用，但在文档中使用

如果我们通过LocationClient的文档，我们可以看到该类已被弃用。

但是不赞成使用的类用于获取当前位置的文档 。

我认为这有点误导，或者我在看不正确的文件？

Google再次发布了一个新的API，但他们没有更新文档：$花了一些时间试图弄清楚它是如何工作的我已经得到它，在这里你有一个完整的例子使用新的/最新的位置服务API …享受开发:)

 import android.location.Location; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView; import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.api.GoogleApiClient; import com.google.android.gms.location.LocationListener; import com.google.android.gms.location.LocationRequest; import com.google.android.gms.location.LocationServices; public class MainActivity extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener { private final String TAG = "MyAwesomeApp"; private TextView mLocationView; private GoogleApiClient mGoogleApiClient; private LocationRequest mLocationRequest; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mLocationView = new TextView(this); setContentView(mLocationView); mGoogleApiClient = new GoogleApiClient.Builder(this) .addApi(LocationServices.API) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .build(); } @Override protected void onStart() { super.onStart(); // Connect the client. mGoogleApiClient.connect(); } @Override protected void onStop() { // Disconnecting the client invalidates it. mGoogleApiClient.disconnect(); super.onStop(); } @Override public void onConnected(Bundle bundle) { mLocationRequest = LocationRequest.create(); mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); mLocationRequest.setInterval(1000); // Update location every second LocationServices.FusedLocationApi.requestLocationUpdates( mGoogleApiClient, mLocationRequest, this); } @Override public void onConnectionSuspended(int i) { Log.i(TAG, "GoogleApiClient connection has been suspend"); } @Override public void onConnectionFailed(ConnectionResult connectionResult) { Log.i(TAG, "GoogleApiClient connection has failed"); } @Override public void onLocationChanged(Location location) { mLocationView.setText("Location received: " + location.toString()); } } 

不要忘记把这个权限添加到你的AndroidManifest.xml文件中：

 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 

注意：如果您只需要获取上一个位置（没有更新），则可以使用OnConnected中的LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient)

Answer 2

某些文档在Google中是旧的（您提到的一些示例仍然使用已弃用的LocationClient ）。 您必须使用位置服务示例中所述的新的GoogleApiClient：

 private GoogleApiClient mGoogleApiClient; mGoogleApiClient = new GoogleApiClient.Builder(context) .addApi(LocationServices.API) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .build() 

而当新客户端连接时，可以使用熔合的位置api，例如：

 LocationServices.FusedLocationApi.requestLocationUpdates(theNewClient, locationRequest, locationListener); 

Answer 3

它看起来像是在开发人员的博客 。 对于LocationClient，您可以将此与LocationServices一起使用，然后将其引导至GeofencingApi 。

Answer 4

LocationClient被删除。 GoogleApiClient是用于Google Play服务位置API的api。

常见场景的示例代码就在这里 ，而且培训课程也随即更新 。

根据文档更新代码
