How to set Different String in a Textview in Fragment while clicking different Button?

Question

I'm new to Android app programming.

I have two Fragments - fragmentA.xml and fragmentB.xml.

In fragmentA there are two Buttons - Button One (id: btnOne) and Button Two (id: btnTwo).

In fragmentB there is TextView (id- textView)

In fragmentB java class there are two String - string1 and string2

Both buttons refers to fragmentB.

I want two set the textView text to string1 when I press Button One and string2 when I press Button Two.

How can I do that?

I was using following code in fragmentB java class to display only string1

public View onCreateView(
    LayoutInflater inflater, 
    ViewGroup container, 
    Bundle savedInstanceState) 
{
    View rootView = inflater.inflate(R.layout.oop_page,container,false);
    TextView textV = (TextView)rootView.findViewById(R.id.textView);
    textV.setText(string1);
    return rootView;
}

Can I use any if-else statement here?

Thanx

make only one string in your global class (accessible to both fragment) and set it to your textview,....just change string on button click it will be automatically disply changed one... — Iamat8, Feb 03 '16 at 16:34
@AnshulJain I use a method to open the FragmentB and I am using the method in Button One and Button Two's onClick method — MaxySpark, Feb 03 '16 at 16:41
@Mohit you mean i should declare a string in MainActivity.java . can you provide me the code. and what if there is more than two botton. I mean for every button different string. — MaxySpark, Feb 03 '16 at 16:50

Create a Global class in your project and define a public string ..

public class Global{
  public static String TEXT = "";
}

In your Fragment A change this TEXT on button click event..

but1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
        Global.TEXT = "string 1";
    }
});
but2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
        Global.TEXT = "string 2";
    }
});

same as on other button if you have

In your FragmentB just setText()....it will take lase value change to Text

text.setText(Global.TEXT);

FragmentA.java

public boolean btn1Clicked, btn2Clicked = false;
        Button button1 = (Button) rootViewfindViewById(R.id.button1);
            button1.setOnClickListener(new View.OnClickListener() {

              @Override
              public void onClick(View v) {
                btn1Clicked = true;
              }
            });

            Button button2 = (Button) rootView.findViewById(R.id.button2);
            button2.setOnClickListener(new View.OnClickListener() {

              @Override
              public void onClick(View v) {
                btn2clicked = true;
              }
            });

FragmentB.java

 public View onCreateView(
        LayoutInflater inflater, 
        ViewGroup container, 
        Bundle savedInstanceState) 
    {
        View rootView = inflater.inflate(R.layout.oop_page,container,false);
        TextView tv1 = (TextView)rootView.findViewById(R.id.textView);
        if(!(FragmentA.btn1Clicked))
         {
        // Not Clicked
         }
        else{
           tv1.setText("Button 1 Clicked!")'
    }
        return rootView;
