我正在使用Fused Location Provider Google API更新我的应用的位置,但是尽管我在获得价值时移动了设备,但它具有相同的位置。请帮我找出我的错吗?
我正在使用ExpandableListAdapter中的按钮。当用户单击那里的按钮时。我的应用获取位置并存储在数据库中。我试图将LocationCallback放置在活动中的任何位置,但是它没有改变。
我的活动:
public class IndexActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
String UserId;
ExpandableListView mExpandableListView;
List<Customer> info;
List<MetterChangeLog> log;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
private LocationSettingsRequest.Builder builder;
private PendingResult<LocationSettingsResult> result;
private final int REQUEST_LOCATION = 200;
private final int REQUEST_CHECK_SETTINGS = 300;
private Location mLastLocation;
FusedLocationProviderClient mFusedLocationClient;
private LocationCallback mLocationCallback;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_index);
try {
GetMetterChangeLogTask mytt = new GetMetterChangeLogTask(IndexActivity.this);
mytt.execute();
log = mytt.get();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(120000); // two minute interval
mLocationRequest.setFastestInterval(120000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
/*if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}*/
mLocationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
for (Location location : locationResult.getLocations()) {
mLastLocation = location;
}
};
};
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addOnConnectionFailedListener(this)
.addConnectionCallbacks(this)
.addApi(LocationServices.API)
.build();
}
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
@Override
protected void onResume() {
super.onResume();
mLocationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
for (Location location : locationResult.getLocations()) {
mLastLocation = location;
}
};
};
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
mFusedLocationClient.requestLocationUpdates(mLocationRequest,
mLocationCallback,
Looper.getMainLooper());
}
}
@Override
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
@Override
public void onConnected(@Nullable Bundle bundle) {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(2000);
mLocationRequest.setFastestInterval(2000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, null);
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
@Override
public void onLocationChanged(Location location) {
mLocationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
for (Location location : locationResult.getLocations()) {
mLastLocation = location;
}
};
};
}
然后我将mLastLocation设置为初始ExpandableListView,如下所示:
mExpandableListView = (ExpandableListView) findViewById(R.id.list_customer);
ExpandableListAdapter adapter = new ExpandableListAdapter(IndexActivity.this,
mExpandableListView, info, SoDoc.substring(0, 1), mLastLocation);
mExpandableListView.setItemsCanFocus(true);
mExpandableListView.setAdapter(adapter);
在ExpandableListAdapter类中,我使用提交按钮创建了一个持有人以获取位置。
groupHolder.submit.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
//button functionalty ...
...
final Customer index = new Customer();
index.setLong(mLastlocation.getLongitude());
index.setLat(mLastlocation.getLatitude());
...
}
我试图在3个地方获得位置并获得相同的价值。请帮助我找到我的错。对不起,我的英语不好。
感谢支持。
