How to give value to previously defined string inside onClick block in android studio

Question

So i have 2 activities that link to each other through an intent, but i need the second page to know what was clicked in the previous page. Heres what i mean.

public class featuredvendors extends AppCompatActivity {


public String nextpageref;

The string i would like to edit is declared above.

t2.setOnClickListener(new View.OnClickListener(){
        public void onClick(View v){
            nextpageref="post1";
            Intent t2 = new Intent(featuredvendors.this, featureddetails.class);

            startActivity(t2);
        }
    });

So essentially, i want to change the value of nextpageref based on what was clicked on. However it seems that i cant change the value inside an onClick block. Is there anyway i can pass the value "post1" to a string, but ONLY when this particular button is clicked? I need it this way because the next page 'featureddetails' needs to know this String value in order to pull the correct information from the DB.

Class names is better to start with capital letters on each word: FeaturedVendors, FeaturedDetails etc — gvlachakis, Mar 29 '17 at 11:50

In the onClick block add this

t2.setOnClickListener(new View.OnClickListener(){
        public void onClick(View v){
            nextpageref="post1";
            Intent t2 = new Intent(featuredvendors.this, featureddetails.class);
t2.putString("key", nextpageref);
            startActivity(t2);
        }
    });

In the next activity get value from this piece of code in onCreate's method

Intent i= getIntent();
String value = i.getStringExtra("key");
Log.e("value", value);

SendingActivity

   Intent intent = new Intent(SendingActivity.this, RecievingActivity.class);
    intent. putString("keyName", value);  // pass your values and retrieve them in the other Activity using keyName
    startActivity(intent);

Second Screen.java

public class newclass extends Activity { private TextView Textv;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.intent);
    Textv = (TextView)findViewById(R.id.tv2);
    Intent i= getIntent();
    i.getStringExtra("keyName");
}

}
