Question

我在Google地图中编写了一个代码，以便hospitals，restaurants和schools加载。我正在使用这些依赖项：implementation 'com.google.android.gms:play-services-maps:15.0.0'和implementation 'com.google.android.gms:play-services-location:15.0.0'。我正在使用Gradle 3.0.0。当我运行我的代码时，我收到此错误：

Activity has leaked window DecorView@92f9f38[] that was originally added here

   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:756)

此错误发生在此代码块中：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            checkLocationPermission();
        }

        //Check if Google Play Services Available or not
        if (!CheckGooglePlayServices()) {
            Log.d("onCreate", "Finishing test case since Google Play Services are not available");
            finish();
        }
        else {
            Log.d("onCreate","Google Play Services available.");
        }

        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }



private boolean CheckGooglePlayServices() {
        GoogleApiAvailability googleAPI = GoogleApiAvailability.getInstance();
        int result = googleAPI.isGooglePlayServicesAvailable(this);
        if(result != ConnectionResult.SUCCESS) {
            if(googleAPI.isUserResolvableError(result)) {
                googleAPI.getErrorDialog(this, result,
                        0).show();
            }
            return false;
        }
        return true;
    }

我该如何解决？是什么造成的？为什么会这样？

Answer 1

将片段事务代码放在

的else部分

if (!CheckGooglePlayServices()) {
 ......
}
else {
    Log.d("onCreate","Google Play Services available.");
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

或者你可以试试;

if(!((Activity)YourActivity.this).isFinishing()) {
     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
     mapFragment.getMapAsync(this);
}

下面提到的代码使用分离的线程来执行..

  int result = googleAPI.isGooglePlayServicesAvailable(this);

这种情况正在发生，因为您的活动正在片段交易期间完成!!

我认为您的代码在销毁活动后尝试获取上下文

活动已泄露窗口DecorView @ 92f9f38 []，此处最初添加错误
