我在GoogleApiClient的本地化中遇到了很大的麻煩。我已經實施內置GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener和LocationListener根本不起作用。似乎這些接口尚未註冊到我的應用程序中。以下是我的代碼。請看方法：onLocationChanged,onConnectionSuspended,onConnected, onConnectionFailed。在我添加的每個示例中，打印LOG的一些文本，並且在這些示例中的任何一個logs都未打印。Android中的GoogleApiClient無法在應用程序中註冊
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener {
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
private GoogleMap mMap;
private Location location;
/////////////////////////////////////////////
private GoogleApiClient mGoogleApiClient;
public static final String TAG = MapsActivity.class.getSimpleName();
private LocationRequest mLocationRequest;
private LatLng latLng;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Create the LocationRequest object
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(10 * 1000) // 10 seconds, in milliseconds
.setFastestInterval(1 * 1000); // 1 second, in milliseconds
dataBaseHelper = new DataBaseHelper(getApplicationContext());
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
/* some code here */
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
@Override
public void onMapReady(final GoogleMap googleMap) {
mMap = googleMap;
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
mGoogleApiClient.connect();
}
private void setUpMapIfNeeded() {
if (mMap == null) {
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMapAsync(this);
if (mMap != null) {
//setUpMap();
}
}
}
@Override
protected void onPause() {
super.onPause();
if (mGoogleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
mGoogleApiClient.disconnect();
}
}
private void handleNewLocation(Location location) {
Log.d(TAG, location.toString());
double currentLatitude = location.getLatitude();
double currentLongitude = location.getLongitude();
final LatLng latLng = new LatLng(currentLatitude, currentLongitude);
setLatLng(latLng);
MarkerOptions options = new MarkerOptions()
.position(latLng)
.title("I am here!");
mMap.addMarker(options);
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.animateCamera(CameraUpdateFactory.zoomTo(15), 2000, null);
generateMap(getLatLng(), "3000");
sItems.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
washLocations.clear();
washLocations.size();
String latitude = String.valueOf(latLng.latitude);
String longitude = String.valueOf(latLng.longitude);
generateMap(getLatLng(), null);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
private void setUpMap() {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
@Override
public void onConnected(@Nullable Bundle bundle) {
Log.d("location test", "tes1");
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (location == null) {
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
} else {
handleNewLocation(location);
}
}
@Override
public void onConnectionSuspended(int i) {
Log.i("faild", "Location services suspended. Please reconnect.");
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if (connectionResult.hasResolution()) {
try {
// Start an Activity that tries to resolve the error
connectionResult.startResolutionForResult(this, CONNECTION_FAILURE_RESOLUTION_REQUEST);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
} else {
Log.i("failds", "Location services connection failed with code " + connectionResult.getErrorCode());
}
}
@Override
public void onLocationChanged(Location location) {
Log.d("location test", "tes2");
handleNewLocation(location);
}
}
正如您在上面看到：
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(10 * 1000) // 10 seconds, in milliseconds
.setFastestInterval(1 * 1000);
地圖應該刷新每10秒 - 所以這意味着它也應該打印Log.d("location test", "tes2");每10秒 - 但事實並非如此。
在這裏，這是我的build.gradle，我把每一個需要libriaries： 應用插件： 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.micha.locationtest"

}
}
useLibrary 'org.apache.http.legacy'
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

不起作用。什麼是'Utilis'？我根本無法導入它... – bielas
忽略那個util只看到我編輯的帖子 –
