I have a problem with my app. I have a MainActivity, where is a drawer with fragments. From Scan fragment I call Scan Activity. This part is workng. And when I press back button, it goes back to MainActivity with ScanFragment. And there is also socket operation to send the code and maybe there is the problem. When I turn off wifi, it shows I/O error in Toast, but when I try to send the data, it goes into black screen. I found the problem in profiler, that MainActivity do not start after closing Scan activity, but the app is still running.
After a while android ask, if close non responding app. I tried to move all classes and functions into MainActivity, but then scanner wont start. Thanks for any help
My code of MainActivity.java:

drawer.addDrawerListener(toggle);
toggle.syncState();

odpoved = spojit.execute("SCAN", kod).get()
is your problem. Calling get() on an AsyncTask blocks the current Thread until the task completes, essentially defeating the purpose of an AsyncTask.
Consider using a callback.
First, make Spojeni a static class:
public static class Spojeni extends AsyncTask<String, Void, String>
This will prevent memory leaks from occurring. I do see some variables that you access inside the parent class, but you can pass them in your call to execute() and retrieve them from your AsyncTask there.
Then, create an interface (can be a child of ScanFragment or in its own file):
public interface OnTaskCompleteListener {
void onTaskComplete(String result);
}
Add a constructor and a global variable to your AsyncTask:
private OnTaskCompleteListener listener;
public Spojeni(OnTaskCompleteListener listener) {
this.listener = listener;
}
And implement onPostExecute():
#Override
public void onPostExecute(String result) {
listener.onTaskComplete(result);
}
When you create an instance of Spojeni:
new Spojeni(new OnTaskCompleteListener() {
#Override
public void onTaskComplete(String result) {
//handle the result
}
});

I want to send data from EditText in child activity to parent activity (MainActivity) and use it as a string parameter (URL) in other methods
Already I am able to send this using intent and extras, also I added textview in method to see if it works, but finally, this textview will be deleted, but I can't use it in other methods

Good day, I have a fragment called MainFragment called from MainActivity. Inside MainFragment I have private OnProgressUpdateListener progressListener; this interface instance helps me talk to ProgressDialog Fragment.

I want to add a search bar where I can search any place as Google maps. The search bar should be in an Auto Complete way.I got this code from https://examples.javacodegeeks.com/android/android-google-places-autocomplete-api-example/
Have a look at the above link.
And these codes where for an ORDINARY APP to get Auto Complete search bar. It doesnt suit for app using fragment. And I dont know how to do it with fragments.
Here is my code
For the Main Activity (ProfileActivity)
public class ProfileActivity extends AppCompatActivity {
final String TAG = this.getClass().getName();
BottomBar mBottomBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}

}
}

dialog.show();
} else {

}
return false;
}
boolean twice;

I have to add a search bar with Auto Complete like Google map.Please with reference of the Link which I have given at starting, Can Anyone code for my MapFragment?
In my project I have just one Activity that have View.
I think that it has two View that switch the View. The first View is my home that has one Button named "play" . when You click play Button in goes to the second View. Second View is my game.
And now my problem is that when I want to use onBackPressed() method in the second View, it closes the Activity. and onBackPressed() method do the same in both View.
How to handle onBackPressed() method in second View that return to the first View.
How to switch the View in onBackPressed()?
I am new with Android and now I really confused.
any suggestion? or any key word to search to solve my problem.
here is my code:

you must use of Override Method for when back button pressed
if you want to stay on currnt activity use like this
#Override
public void onBackPressed() {
return;
}
if you want to use double click to exit and one click to stay you can use like this
first define a variable for double click
boolean doubleBackToExit = false;
and the Override backbutton method
#Override
public void onBackPressed() {
if (doubleBackToExit) {
//on double back button pressed
return;
}
this.doubleBackToExit = true;
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
doubleBackToExit=false;
}
}, 2000);
}
Then do this.
#Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent(MainActivityPhase2.this, GlobalSearch.class);
startActivity(intent);
finish();
}
Just don't call the super.onBackPressed() everytime.
#Override
public void onBackPressed() {
if (isFirstView()) {
super.onBackPressed();
} else {
switchToFirstView();
}
Call in only when there isn't any last view available. Or where you want to close the App. The code will finish your activity when you are on the first activity. And switch to first activity if you are on second activity.
Just replace my methods as per your code.
Overriding onBackPressed() of the activity and provide your screen where you want to go.
onBackpressed() check which is the current view you are showing and according to move to the first view.
in your second class Cocos2dxActivity, place this code.
#Override
public void onBackPressed() {
this.finish();
}
If you have just one activity with two View you can use Fragments.
Using Fragments, Activity.OnBackPressed() will remove last fragment in the stack and you can resolve your problem.
So, in the activity you have to put a container in xml layout file:
<FrameLayout android:id="#+id/container" android:layout_width="match_parent"
android:clickable="true" android:layout_height="match_parent"/>
In the Activity java file:
getFragmentManager().beginTransaction()
.add(R.id.container,new YourHomeFragment())
.commit();
So to add second Fragment you can use this code:
getFragmentManager().beginTransaction()
.add(R.id.container,new YourPlayFragment())
.addToBackStack("YourPlayFragment") //string what you want
.commit();
Pay attention: you can call this code or in YourHomeFragment class (into button clickListener) or in your Activity (using a callback system). For example:
In YourHomeFragment -->
playButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getFragmentManager().beginTransaction()
.add(R.id.container,new YourPlayFragment())
.addToBackStack("YourPlayFragment") //string what you want
.commit();
}
});
In this way, you have to declare two layout xml file for fragments and one for Activity.
List of java and relative xml files:
MainActivity.java
activity_main.xml
YourHomeFragment.java
fragment_your_home.xml <-- insert here your first View
YourPlayFragment.java
fragment_your_play.xml <-- play view
I'm trying to implement the back press feature for a fragment and activity regarding the navigation drawer but it's not working. Does anyone know what I'm doing wrong / what is missing and what needs to be done in order to fix this?

EDIT:
You can use LocalBroadcastManager to update fragment when in activity back is pressed:
in fragment add new BroadcastReceiver() Instance:
BroadcastReceiver onNotice = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// do stuff when back in activity is pressed
// headerResult.closeDrawer();
}
};
and register it with tag in onCreate method:
LocalBroadcastManager.getInstance(this).registerReceiver(onNotice,
new IntentFilter("BACKPRESSED_TAG"));
Then, in Activity OnBackPressed method call broadcast:
LocalBroadcastManager.getInstance(context).sendBroadcast(new Intent("BACKPRESSED_TAG"));
Do you have a reference inside your code to the interface? Looks like you're calling that interface directly hence the errors. Try renaming that method too. It might be conflicting with the super class's onBackPressed method.
Your problem is that your interface is named exactly as the property you are trying to use.
Rename it and use a instance.
#Override
public void onBackPressed() {
OnBackPressedListener instance = getSettedListener();
if (result.isDrawerOpen()) {
result.closeDrawer();
} else {
return instance.onBackPressed();
}
}
public interface OnBackPressedListener {
boolean onBackPressed();
}
This code would compile if you also implement the method getSettedListener on your code (that could be like the following):
public OnBackPressedListener getSettedListener() {
return new OnBackPressedListener(){
boolean onBackPressed(){
if(shouldConsumeBack)
return consumeBack();
else return false;
};
}
}
But this code could return the Fragment that does implements the method.
