Android : Pass value of TextView on Click

In my xml(activity_main.xml) there are 4 Textviews.

Textview textview1,textview2,textview3,textview4.

and there values are value1,value2,value3,value4.

In MainActivity.java This is my onCreate and onClick Methods,

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView tv1=(TextView)findViewById(R.id.textView1);
    TextView tv2=(TextView)findViewById(R.id.textView2);
    TextView tv3=(TextView)findViewById(R.id.textView3);
    TextView tv4=(TextView)findViewById(R.id.textView4);
    tv1.setOnClickListener(this);
    tv2.setOnClickListener(this);
    tv3.setOnClickListener(this);
    tv4.setOnClickListener(this);
}
public void onClick(View v) {
 String value;
}

I want to set value of Textview which has been clicked in my onClick method

ie, if user clicked on Textview1-----String value=value1

if user clicked on Textview2-----String value=value2

if user clicked on Textview3-----String value=value3

if user clicked on Textview4-----String value=value4

Can anyone please help me to get this.
