menuitem - How to change the Text color of Menu item in Android?

Can I change the background color of a Menu item in Android?

Please let me know if anyone have any solution to this. The last option will be obviously to customize it but is there any way for changing the text color without customizing it.

android - How to add dividers and spaces between items in RecyclerView

android - How to add dividers and spaces between items in RecyclerView

This is an example of how it could have been done previously in the ListView class, using the divider and dividerHeight parameters:

<ListView
    android:id="@+id/activity_home_list_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@android:color/transparent"
    android:dividerHeight="8dp"/>

However, I don't see such possibility in the RecyclerView class.

<android.support.v7.widget.RecyclerView
    android:id="@+id/activity_home_recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical"/>

In that case, is it ok to define margins and/or add a custom divider view directly into a list item's layout or is there a better way to achieve my goal?

Error: Unfortunately you can't have non-Gradle Java modules and > Android-Gradle modules in one project

Error: Unfortunately you can't have non-Gradle Java modules and > Android-Gradle modules in one project

I have an IntelliJ 14.1.2 Project consisting of two modules - one is an Android Gradle based module and the other is a Spring Java-based module with Maven.

gps-trackman.v1 is my root project and I've not configured any outputs or facets for this project. The app is my android gradle module and I've configured Android and Android-Gradle Facet for this project and gps-trackman isn't my Spring Maven Project. I want to be able to build everything all together. Is it possible?

I now get this error message in my IntelliJ Eventlog

Unsupported Modules Detected: Compilation is not supported for following modules: gps-trackman, gps-trackman.v1, app. Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project.

The project 'gps-trackman.v1' is not a Gradle-based

Is this error just due to a misconfiguration of my project or is it really not possible to have a maven module and a Gradle module in one project?

Do I have to configure any Facets for the root project? Alternatively, do I have to convert my maven to gradle?

Is there a convenient way to create Parcelable data classes in Android with Kotlin?

Is there a convenient way to create Parcelable data classes in Android with Kotlin?

I'm currently using the excellent AutoParcel in my Java project, which facilitates the creation of Parcelable classes.

Now, Kotlin, which I consider for my next project, has this concept of data classes, that automatically generate the equals, hashCode and toString methods.

Is there a convenient way to make a Kotlin data class Parcelable in a convenient way (without implementing the methods manually)?

android - onActivityResult() & onResume()

Could someone tell me which gets called first, is it onActivityResult() or is it onResume()? Example:

Activity A calls startActivityForResult() to start Activity B. B executes, completes and returns a result to A, but which method of A is called first, onActivityResult() or onResume()?

I know someone has answered this question already by referring to the Activity Docs, however I couldn't find in there myself.

android - Build and Install unsigned apk on device without the development server?

As I am new in react-native so if there is anything wrong in steps let me know.

I have build a react native android app using the command as per documentation

react-native android

while running on device the following command was used

react-native run-android

which gives me the output of 2 apk files in my projectfolder/android/app/build/outputs/apk

enter image description here

now when I use to install this apk after the installation it ask for an development server to connect to bundle the JS. But my requirement is that the user doesn't have to struggle with the development server just he needs to install the apk and everything is done.

Have gone through some stackoverflow Questions but not helpful to build unsigned apk which doesn't require development server.

Can you guys help me finding the way that how to build and unsigned apk in react native?

Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

I have an application with three tabs.

Each tab has its own layout .xml file. The main.xml has its own map fragment. It's the one that shows up when the application first launches.

Everything works fine except for when I change between tabs. If I try to switch back to the map fragment tab, I get this error. Switching to and between other tabs works just fine.

What could be wrong here?

java - How to send data from DialogFragment to a Fragment?

java - How to send data from DialogFragment to a Fragment?

I have a fragment that opens a Dialogfragment to get user input (a string, and an integer). How do I send these two things back to the fragment?

Here is my DialogFragment:

public class DatePickerFragment extends DialogFragment {
    String Month;
    int Year;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        getDialog().setTitle(getString(R.string.Date_Picker));
        View v = inflater.inflate(R.layout.date_picker_dialog, container, false);

        Spinner months = (Spinner) v.findViewById(R.id.months_spinner);
        ArrayAdapter<CharSequence> monthadapter = ArrayAdapter.createFromResource(getActivity(),
                R.array.Months, R.layout.picker_row);
              months.setAdapter(monthadapter);
              months.setOnItemSelectedListener(new OnItemSelectedListener(){
                  @Override
                  public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int monthplace, long id) {
                      Month = Integer.toString(monthplace);
                  }
                  public void onNothingSelected(AdapterView<?> parent) {
                    }
              });

        Spinner years = (Spinner) v.findViewById(R.id.years_spinner);
        ArrayAdapter<CharSequence> yearadapter = ArrayAdapter.createFromResource(getActivity(),
             R.array.Years, R.layout.picker_row);
        years.setAdapter(yearadapter);
        years.setOnItemSelectedListener(new OnItemSelectedListener(){
          @Override
          public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int yearplace, long id) {
              if (yearplace == 0){
                  Year = 2012;
              }if (yearplace == 1){
                  Year = 2013;
              }if (yearplace == 2){
                  Year = 2014;
              }
          }
          public void onNothingSelected(AdapterView<?> parent) {}
        });

        Button button = (Button) v.findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
           public void onClick(View v) {
               getDialog().dismiss();
            }
        });

        return v;
    }
}

I need to send the data after the button click and before getDialog().dismiss()

Here is the fragment that data needs to be sent to:

public class CalendarFragment extends Fragment {
int Year;
String Month;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int position = getArguments().getInt("position");
    String[] categories = getResources().getStringArray(R.array.categories);
    getActivity().getActionBar().setTitle(categories[position]);
    View v = inflater.inflate(R.layout.calendar_fragment_layout, container, false);    

    final Calendar c = Calendar.getInstance();
    SimpleDateFormat month_date = new SimpleDateFormat("MMMMMMMMM");
    Month = month_date.format(c.getTime());
    Year = c.get(Calendar.YEAR);

    Button button = (Button) v.findViewById(R.id.button);
    button.setText(Month + " "+ Year);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
           new DatePickerFragment().show(getFragmentManager(), "MyProgressDialog");
        }
    });
   return v;
  }
}

so once the user selects a date in the Dialogfragment, it must return the month and year.

Then, the text on the button should change to the month and year specified by user.
