Question

我有这段代码：

if (distance < 1f) // or some distance
{
    Gameobject mygo = GameObject.Find("GameManager"); // or some other method to get gameobject.
    mygo.GetComponent<casting>().enabled = false;
}

行：location.addCompleteListener被Android Studio标记为未选中，它会使应用崩溃。所以我必须以某种方式“检查”它。这是在Android Studio的最新更新补丁之后发生的。

我该如何解决这个问题？

Answer 1

如果我有50个以上的代表，我会发表评论。

无论如何，您可以继续使用

.addOnCompleteListener(new OnCompleteListener<Location>(){
});

通过，添加到@ nope4561759所说的内容，将<Location>添加到onComplete（）重写方法的Task参数上，如下所示：public void onComplete(@NonNull Task<Location> task) {…}

Answer 2

尝试更改：

final Task location = mFusedLocationClient.getLastLocation();
    location.addOnCompleteListener(this, new OnCompleteListener() {

到此：

final Task<Location> location = mFusedLocationClient.getLastLocation();
    location.addOnCompleteListener(this, new OnCompleteListener<Location>() {

Answer 3

 private void getDeviceLocation() {
    Log.d(TAG, "getDeviceLocation: getting the devices current location");
    FusedLocationProviderClient mfusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(MainActivity.this);
    try {
        if (mLocationPermissionGranted) {
            final Task<Location> location = mfusedLocationProviderClient.getLastLocation();
            location.addOnCompleteListener(this, new OnCompleteListener<Location>() {

                @Override
                public void onComplete(@NonNull Task task) {
                    if (task.isSuccessful()) {
                        Log.d(TAG, "onComplete: found location");
                        try {
                            Location currentLocation = (Location) task.getResult();
                            //globalLatitude = currentLocation.getLatitude();
                            //globalLongitude = currentLocation.getLongitude();
                        } catch (Exception e) {
                            Toast.makeText(getApplicationContext(), "Please turn on your GPS", Toast.LENGTH_SHORT).show();
                        }
                    } else {
                        Log.d(TAG, "onComplete: Location not found");
                        Toast.makeText(MainActivity.this, "Cannot find current location", Toast.LENGTH_SHORT).show();
                    }
                }
            });
        }
    } catch (SecurityException e) {
        Log.e(TAG, "getDeviceLocation: Security Exception" + e.getMessage());
    }
}

addOnCompleteListener未被选中，导致应用程序崩溃。

addOnCompleteListener未选中并崩溃应用程序
