Make Mapbox markers clickable and return the ID of the marker

So I've made a MapActivity which shows a MapBox map.
Then I load in all my markers(pins, which are eventually Point objects with longitude and latitude) from the database into a List< Features > markerCoordinates. markerCoordinates is then given through GeoJsonSource().
Now all my markers are displayed on the map.
Now I can't figure out how to make a marker clickable, and when clicked I need to obtain the ID of the marker so I can later on redirect to another Activity and then load in all data based on that ID. This ID of the pin needs to be the same as the ID from the database.
Mapbox Documentation doesn't really helped me out with this problem.
Does any one know how to implement this?

First, you should implement the onMapClick or onMapLongClick methods, so that you can handle all map clicks and retrieve the data you need.
The steps to get the marker Id on every click are roughly these:
Check whether the click was on a marker or elsewhere.
You can do this by querying the source layer (your GeoJsonSource) and checking whether there is a feature nearby the clicked spot.
If a feature was found, get the property you need.
You could use feature.getProperties() to get all the properties or feature.getStringProperty("name_of_the_property") to get a specific one. See more here.
Check this example to see how to implement all of this.

Mimic the back button on the actionbar

So I have the action bar back button which returns me from an activity to my main activity. The problem I have is that it calls loadData() (which loads data from an API) when you press the action bar back button.
If I press the back button on the device (the button beside the home button) then I will be brought back to the previous view (the mainactivity) and won't have to call the API again.
So I'm trying to find a way to mimic the physical back button as an action bar widget.
I don't want MainActivity's code to be called again as it will execute another API call (I can only have 5 per minute) and it is also slower. I just want it to go back to the view I was just at.
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private RecyclerView.Adapter adapter;
private ArrayList<ListItem> listItems;
private String defaultQuery = "ham";
private String builtURL;
#Override

In your manifest xml
set
<activity
android:name=".your_activity"
android:label="#string/title_activity_sign_up"
android:parentActivityName=".whateveractivity"
android:screenOrientation="portrait" >
</activity>
then in code
#Override
public void onBackPressed() {
NavUtils.navigateUpFromSameTask(this);
// Otherwise defer to system default behavior.
super.onBackPressed();
}
To elaborate what you are doing is overriding the onbackpressed hardware button.
Also make your parent activity's launchmode singleInstance.

button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent goToBrowser = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(goToBrowser);
finish();
}
});

Override Back button to save data using SharedPreferences

When using my app the users inputs data and the data is supposed to be saved. However at the moment the back button erases the data from the EditText. Here is my java file for the activity, this activity is activated by a button press from the Main Activity. I've already tried to override the back button with no success. Any suggestions?

// as you specify a parent activity in AndroidManifest.xml.

return true;
}
switch(item.getItemId())
{
case R.id.home:
SavePreferences();
startActivity(new Intent(getApplicationContext(), MainPage.class));
break;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onBackPressed() {
SavePreferences();
super.onBackPressed();
}
}

You should save/restore the persistent state of the activity in onSaveInstanceState/onRestoreInstanceState methods. You already override those, so just call SavePreferences/LoadPreferences from them.
Overriding the back button is not a good idea and saving state in onDestroy is also not recommended. Either onSaveInstanceState or onPause is intended for that.

If the data needs to be saved whenever the user leaves that activity, you could approach the problem with a TextWatcher. Override the onTextChanged() method of the TextWatcher with something like this:
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (s.length > 0) coName = s;
}
And then override onPause() to save the state of your variables if necessary.

[Edited] You can try:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
SavePreferences();
finish(); //<-- You need finish your activity after saved
return true;
}
return super.onKeyDown(keyCode, event);
}

There already is another method with the same signature

Thanks for your response.

You have 2 onCreate functions in the same Activity. You can only have one. That's why its complaining that there is already a method with same signature. Delete one of them and move the stuff from one to other. As mentioned by #Ravn in comments, you can have multiple functions with same name but ofcourse with different arguments.

You cannot have method with same signature twice

OnClickListener for launching webview from a listview row

A search api is returning me some meta data along with a URL "eventURL". I am placing the data in the listview, each row containing some data and a unique URL.I want when the user taps on the row in the listview,that unique URL should open in a webview.I have created a WebViewActivity for it,I am having issue with implementing the onClickListener.

Thanks.

You need to use OnItemClickListener:
MainActivity implements OnItemClickListener {
onCreate() {
m_search_results.setOnItemClickListener(this);
Make this method:
onItemClick(AdapterView<?> parent, View view, int position, long id) {
url = JSON.getHowever(position);
//get the intent, load the url, and launch the activity
}
You also need to handle the intent in your WebViewActivity, but that's beside the question
