I am unable to change the view visibility inside other function rather than onCreate method. Its working only at time of onCreate is called.
public class CameraXActivity extends AppCompatActivity {
...
public Group fipGroup;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camerax_layout); // Created xml using constraintLayout.
//intial setup
fipGroup = (Group)findViewById(R.id.fip_group);
startCamera();
//hideFipGroup(); <<--- This is working
}
private void hideFipGroup() {
Log.d(TAG, "=== hideFipGroup ===");
fipGroup.setVisibility(View.INVISIBLE);
}
private void startCamera() {
CameraX.unbindAll();
preview = setPreview();
imageAnalysis = setImageAnalysis();
//bind to lifecycle:
CameraX.bindToLifecycle(this, preview , imageAnalysis);
preview.enableTorch(true);
}
private ImageAnalysis setImageAnalysis() {
hideFipGroup() // This is working
imageAnalysis.setAnalyzer(
new ImageAnalysis.Analyzer() {
#Override
public void analyze(ImageProxy image, int rotationDegrees) {
hideFipGroup() // Exactly, Failed at this place.
}
}
)
}
}
Edit Update:
It's failing to update on the analyze method of imageAnalysis. Just to test, called toast message which is showing on the UI. But am not able to control the UI.
private void raiseToast(String msg) {
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
Toast toast = Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 500);
toast.show();
}
});
}
The problem is with Group visibility on constraint Layout.
private void setGroupVisiblity(Group group, int visibility) {
group.setVisibility(visibility);
group.requestLayout();
}
or manually turn off each views in the group:
private void setGroupVisibility(ConstraintLayout layout, Group group, Integer visibility) {
int[] refIds = group.getReferencedIds();
for (int id : refIds) {
layout.findViewById(id).setVisibility(visibility);
}
}
or upgrade to ConstraintLayout version 2.0.0 beta 6
source: Can't set visibility on constraint group
Please try to view.post or runOnUIThread method.
so like this.
private ImageAnalysis setImageAnalysis() {
hideFipGroup() // This is working
imageAnalysis.setAnalyzer(
new ImageAnalysis.Analyzer() {
#Override
public void analyze(ImageProxy image, int rotationDegrees) {
fipGroup.post(new Runnable() {
#Override
public void run() {
hideFipGroup(); // Exactly, Failed at this place.
}
});
}
}
)
}
Or you can simply call view.post() method in hideFipGroup() method
private void hideFipGroup() {
Log.d(TAG, "=== hideFipGroup ===");
fipGroup.post(new Runnable() {
#Override
public void run() {
fipGroup.setVisibility(View.INVISIBLE);
}
});
}
you should check the function you called. Remember that you can only update the UI in the main thread
I'm trying to catch onMeetingStatusChanged event. But for my case, the onMeetingStatusChanged is sometimes invoked, not all the time. Below is my implemented code:
#Override
protected void onCreate(Bundle savedInstanceState) {
registerListener();
InitAuthSDKHelper.getInstance().initSDK(this, new InitAuthSDKCallback() {
#Override
public void onZoomSDKInitializeResult(int i, int i1) {
}
#Override
public void onZoomAuthIdentityExpired() {
}
});
}
private void registerListener() {
ZoomSDK zoomSDK = ZoomSDK.getInstance();
MeetingService meetingService = zoomSDK.getMeetingService();
if (meetingService != null) {
meetingService.addListener(this);
}
}
#Override
public void onMeetingStatusChanged(MeetingStatus meetingStatus,
int errorCode,
int internalErrorCode) {
LogD.d(TAG, String.valueOf(meetingStatus));
if (meetingStatus == MeetingStatus.MEETING_STATUS_IDLE) {
layout_zoom_loading.setVisibility(View.VISIBLE);
} else {
layout_zoom_loading.setVisibility(View.GONE);
}
if(meetingStatus == MeetingStatus.MEETING_STATUS_FAILED
&& errorCode == MeetingError.MEETING_ERROR_CLIENT_INCOMPATIBLE) {
Toast.makeText(this, "Version of ZoomSDK is too low!", Toast.LENGTH_LONG).show();
}
}
public void joinMeeting(String meetingNo, String meetingPassword) {
ZoomSDK zoomSDK = ZoomSDK.getInstance();
if (!zoomSDK.isInitialized()) {
Toast.makeText(this, getString(R.string.msg_zoom_init_fail), Toast.LENGTH_LONG).show();
return;
}
JoinMeetingHelper.getInstance().joinMeetingWithNumber(this, meetingNo, meetingPassword);
}
I see the cause of this problem. We need to separate the initSDK method to BaseActivity class. So when user forward into the next Activity which runs Zoom meeting, onMeetingStatusChanged always be invoked.
I am trying to launch the NavigationLauncher.startNavigation, from another activity but am unable to do so. I have a button in the second activity which I want to use to start the navigation.
Any suggestions are welcome. Thanks
Here is my code:
/*
fabstart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean simulateRoute = false;
NavigationLauncherOptions options = NavigationLauncherOptions.builder()
.directionsRoute(route)
.shouldSimulateRoute(simulateRoute)
.build();
// Call this method with Context from within an Activity
NavigationLauncher.startNavigation(MainActivity.this, options);
}
});
*/
fabstart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this, Before_Go.class);
startActivity(intent);
// Here is where I want to go to a new activity, inside this activity have a button to
// launch the "NavigationLauncher.startNavigation"
}
});
NavigationLauncher.startnavigation() opens a new activity that handles the navigation. Therefore it does not matter from where it is called. However, wherever it is called from, the NavigationLauncher must be defined, and the options object that is passed as the second parameter has to contain the directionsRoute object.
Can you please share code of the activity from which you call it, as well as how you initialize and define the options object?
thanks for your response to my question. I am new to stakoverflow, so i hope i get this additional posting of code right.

I assume that the application crashes once the activity "Go.java" is launched.
The problem appears to be that you are not instantiating the Mapbox object in this activity. You are doing it correclty in your "mainactivity.java" however you are missing it in "go.java". Make sure to have the line Mapbox.getInstance(this, getString(R.string.access_token)); also in your "go.java" activity before calling setContentView()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Mapbox.getInstance(this, getString(R.string.access_token));
setContentView(R.layout.activity_main);
So, I'm using version Mapbox Navigation 0.3.1, I'm fetching route from private OSRM server. Snap-to-route and other features are just working fine, however when 1st step finishes navigation wouldn't proceed to the next step and offRoute method is being called. I'm stuck here for like 1-2 months. I would appreciate any help.
Below, my code snippet of Mapbox Navigation implementation.
public class MapActivity implements MapboxMap.OnMarkerClickListener
,OnMapReadyCallback, AlertLevelChangeListener, ProgressChangeListener, OffRouteListener
,NavigationEventListener, LocationEngineListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fabStartNavigation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// star Navigation
startNavigation();
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
// Remove all navigation listeners being used
mNavigation.removeNavigationEventListener(this);
mNavigation.removeAlertLevelChangeListener(this);
mNavigation.removeProgressChangeListener(this);
mNavigation.removeOffRouteListener(this);
// End the navigation session
mNavigation.endNavigation();
mapView.onDestroy();
}
//navigation controller
private void startNavigation(){
mNavigation.addNavigationEventListener(this);
mNavigation.addAlertLevelChangeListener(this);
mNavigation.addOffRouteListener(this);
mNavigation.addProgressChangeListener(this);
mNavigation.setSnapToRoute(true);
/*LocationEngine mLocationEngine = LostLocationEngine.getLocationEngine(this);
// mNavigation.setLocationEngine(mLocationEngine);*/
mLocationEngine = LostLocationEngine.getLocationEngine(this);
mLocationEngine.setPriority(LocationEnginePriority.HIGH_ACCURACY);
mLocationEngine.addLocationEngineListener(this);
mLocationEngine.activate();
mNavigation.startNavigation(mPlannedRoute);
}
// navigation listeners
#Override
public void onAlertLevelChange(int alertLevel, RouteProgress routeProgress) {
switch (alertLevel) {
case HIGH_ALERT_LEVEL:
break;
case MEDIUM_ALERT_LEVEL:
break;
case LOW_ALERT_LEVEL:
break;
case ARRIVE_ALERT_LEVEL:
break;
case NONE_ALERT_LEVEL:
break;
case DEPART_ALERT_LEVEL:
break;
}
}
#Override
public void onProgressChange(Location location, RouteProgress routeProgress) {
}
#Override
public void userOffRoute(Location location) {
}
#Override
public void onRunning(boolean running) {
}
#Override
public void onConnected() {
mNavigation.setLocationEngine(mLocationEngine);
mLocationEngine.requestLocationUpdates();
}
#Override
public void onLocationChanged(Location location) {
}
}
This sounds like your running into a really old bug that has since been fixed. My advice would be to either upgrade to 0.4.0 or the 0.5.0-snapshot.
I'm getting problems using MapFragment + ListFragment in an Activity,
when I use show() and hide() method, everything works ok, but when I have my application in background and I return, I get the GoogleMap stunned or blocked, and I don't know what to do to solve that. The only solution I got to work fine, is using replace transactions, but I don't like this way, because in every transaction we should initiate all map place balloons, and it doesn't keep your last camera location, so... I don't know what to do.
PS: I use SherlockActionBar
Thanks in advance:

I was also facing the same problem in the new maps api(Maps V2 android).
But i solved it by overriding onSaveInstance and onRestoreInstance method in the container activity..
and not calling super.onSaveInstance(). and super.onRestoreInstance().
This is just a temporary hack.. but i think u will be up and running with your beautiful app..
