Get EditText value on different fragment

Question

I am trying to get some text from editTexts on different fragments. So what I do first is define my mPager and mPagerAdapter:

a_Atenuacion Activity

public class a_Atenuacion extends FragmentActivity{

    private static final int NUM_PAGES = 3;
    /**
     * The pager widget, which handles animation and allows swiping horizontally to access previous
     * and next wizard steps.
     */
    private ViewPager mPager;

    /**
     * The pager adapter, which provides the pages to the view pager widget.
     */
    private PagerAdapter mPagerAdapter;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.a_dat_viewpager);

        // Instantiate a ViewPager and a PagerAdapter.
        mPager = (ViewPager) findViewById(R.id.pager);
        mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
        mPager.setAdapter(mPagerAdapter);


    }
    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
        public ScreenSlidePagerAdapter(FragmentManager fm) {
            super(fm);
        }
        @Override
        public Fragment getItem(int position) {
            switch(position){
                case 0:
                    return new a_Dat_Inicio1();
                case 1:
                    return new a_Dat_Inicio2();
                case 2:
                    return new a_Dat_Inicio3();
            }
            return null;
        }
        @Override
        public int getCount() {
            return NUM_PAGES;
        }
    }
}

Then I get my 3 fragments classes (Both 1st and 2nd layouts have an editText, but the 3rd one has an editText and a button). The button function is that when I am in the last fragment (fragment3) it take info form (different editTexts) and send to another activity.

a_Dat_Inicio1 Fragment

public class a_Dat_Inicio1 extends Fragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("Test", "hello");
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.a_dat_inicio1, container, false);

        return view;  
    }
}

a_Dat_Inicio3 Fragment

public class a_Dat_Inicio3 extends Fragment {

    EditText edit3;
    EditText edit2;
    EditText edit1;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("Test", "hello");
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.a_dat_inicio3, container, false);


        edit1 = (EditText)getActivity().findViewById(R.id.editText1);
        final String edit11 = edit1.getText().toString();
        edit2 = (EditText)getActivity().findViewById(R.id.editText2);
        final String edit22 = edit2.getText().toString();
        edit3 = (EditText)view.findViewById(R.id.editText3);
        final String edit33 = edit3.getText().toString();

        Button but=(Button) view.findViewById(R.id.button);

        but.setOnClickListener(new View.OnClickListener(){
            public void onClick(View v) {

                //Creamos el bundle
                Bundle bundle = new Bundle();
                //Le ponemos la variable parametro con el contenido (key, valor)
                bundle.putString("edit3", edit33);
                bundle.putString("edit2", edit22);
                bundle.putString("edit1", edit11);
                Intent net= new Intent(v.getContext(),Prueba1.class);
                net.putExtras(bundle);
                startActivity(net);

            }
        });

        return view;
    }
}

Finally I get bundle on another activity (Prueba1.class) and it is curious that I only get result for editText1 (on 1st fragment) and rest are null.

Can anybody give me a help?

Thanks in advance.

Answer 1

finally I get over an interface, that is the only way I think to get soemthing on already defined fragments.

My code get like this:

1st define an interface

public interface OnEditTextChanged {

public void onEditPressed1(String edit1);

public void onEditPressed2(String edit1);

public void onEditPressed3(String edit1);

Then fragment activity:

public class a_Dat_Inicio1 extends Fragment {

EditText edit;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("Test", "hello");
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.a_1dat_inicio1, container, false);
    init (view);

    return view;
}

OnEditTextChanged editListener;
@Override
public void onAttach(Activity activity){
    super.onAttach(activity);
    try{
        editListener=(OnEditTextChanged) getActivity();
    }catch(ClassCastException e){
        throw new ClassCastException(activity.toString()+"must implemnt onEditPressed");
    }
}

private void init(View view) {
    edit=(EditText) view.findViewById(R.id.editText1);

    //cada vez que se modifique texto llamar
    edit.addTextChangedListener(new TextWatcher() {

        @Override
        public void afterTextChanged(Editable s) {
            final String edit11 = edit.getText().toString();
            editListener.onEditPressed1(edit11);

        }
    });

And finally on our main activity, call the method:

public class a_Atenuacion extends FragmentActivity implements OnEditTextChanged {

String dat1;
String dat2;
String dat3;

private static final int NUM_PAGES = 3;
private PagerAdapter mPagerAdapter;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.a_1dat_viewpager);

    // Instantiate a ViewPager and a PagerAdapter.
    mPager = (ViewPager) findViewById(R.id.pager);
    mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
    mPager.setAdapter(mPagerAdapter);


    //HERE DO WHATEVER YOU WANT WITH THE DATA CAUGTH ON THE EDIT 1 METHOD


}


@Override
public void onEditPressed1(String edit1) {

    if(mPager.getCurrentItem()==0){
        dat1=edit1;
        Toast bread = Toast.makeText(getApplicationContext(), "edit1", Toast.LENGTH_LONG);
        bread.show();
    }
}

HOPE this help someone!!!

In any way thanks!!!
