it's better, you can use listView then automatically shows your data in every single row... — Tanim reja

or if you still want to do this using View then you have created at-least 4 View object in your xml file . — Tanim reja

Try this First import import android.view.View; then write this line in your onCreate () method

 View v = (View)findViewById(R.id.linea);

But it is not important to make an object ( of this View) for visibility . without any object a View would visible in your layout.

Add View into your activity after setcontentview(R.layout.layout)

 View v = (View)findViewById(R.id.linea);
