将按钮名称从 MainActivity 发送到 Fragment

Question

I'm new in Android Studio JAVA development and this is my first project and expérience with both JAVA and android studio. My problem is that I'm trying to send the Button Name by double-clicked from the Main Activity called BardoMap to a Tab fragment ( to specific Fragment called EnglishBardoFragment ) so I can use the Name button to call some data from the FireBase. I tried to use Bundle at all but I couldn't find the right solution to only send the button name to the Fragment I manage to do all the rest of the work can anyone please help me with some idea or information about how to that value from the activity to the specific fragment

this is the code of the MainActivity BardoMap

public class BardoMap extends AppCompatActivity   {
     private Button AddBardobtn;
     private Button BackB;
     private Button SavePositionB;
     private ViewGroup rootLayout;
     private int _xDelta;
     private int _yDelta;
     private int X ;
     private int Y ;

    RelativeLayout relativeLayout;
    DatabaseReference savig;
    Button   button1;
    int i = 0 ;
    int j  ;

    public String NameButton;
     private    long startTime ;
    private  int clickCount;
    private long duration ;
    static final int MAX_DURATION = 500;
    List<Button> Listbuttons = new ArrayList<Button>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_bardo_map);
        Bundle bundle = new Bundle();
        bundle.putInt("SIDE",2);

        savig = FirebaseDatabase.getInstance().getReference();

        rootLayout = findViewById(R.id.view_root);
        SavePositionB = findViewById(R.id.SavePositionB);


        relativeLayout = findViewById(R.id.view_root);
         FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction t = manager.beginTransaction();
        EnglishBardoFragment engB = new EnglishBardoFragment();

       DatabaseReference usersRef = savig.child("Positions");
       usersRef.addValueEventListener(new ValueEventListener() {

                        button1.setId(i);
                        button1.setText(uid);

                        _Position.setXPosition(snapshot1.child("xposition").getValue().toString());
                        _Position.setYPosition(snapshot1.child("yposition").getValue().toString());

this is My SectionsPagerAdapter for the fragment Tab

    }

    @Override

      Fragment fragment = null;
      switch (position)
      {
          case 0 :
              fragment  = new EnglishBardoFragment();
              /*Bundle bundle = new Bundle();
              bundle.getString("edttext");
              String test =  bundle.getString("edttext");
              bundle.putString("edttext1", "test");
              fragment.setArguments(bundle);*/
              break;
          case 1 :
              fragment = new FrenchBardo();
              break;
          case 2 :
              fragment = new ArabicBardoFragment();

      }
      return fragment;
    }

    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return mContext.getResources().getString(TAB_TITLES[position]);

    @Override

PS: I delete some Unesesery function from my code because of the maximum code line that's why some function are culled but don't exist

Answer 1

I found a solution by using PowerPreference

I did this in my MainActivity

 NameButton = ((Button) v).getText().toString();
 PowerPreference.getDefaultFile().putString("key",NameButton);

Then I called it the fragment

value = PowerPreference.getDefaultFile().getString("key", NameButton);
