You need to use setContentView with the layout which contains textview1 i.e You need to define the layout in your Activity

Your app is getting crash because your class does not have a reference of your activity layout. You must set layout. 

        protected void onCreate(Bundle savedInstanceState) 
        {
                super.onCreate(savedInstanceState);
    //Set setContentView in your code for example //setContentView(R.layout.activity_main);
    //activity_main is my layout in projectfolder> res> layout> activity_main.xml 
    // so put reference of your layout in it.

        setContentView(R.layout.<yourLayout>);     
        TextView text = (TextView) findViewById(R.id.textView1);
        text.setText("how to set Text");
        }

Your app will really crash because you didn't put the setContentView() code in your code:

try this one:

public class settext extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_layout); //PUT THIS ON YOUR CODE

        TextView text = (TextView) findViewById(R.id.textView1);
        text.setText("how to set Text");

    }
}

Actually you need to add a layout (View) in which textView1 would be there For example try this : 

setContentView(R.layout.x1);

so your code would be like that

public class settext extends Activity
{

protected void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.x1);

TextView text = (TextView) findViewById(R.id.textView1);
text.setText("how to set Text");





}

You need to call setContentView(your_layout) before you can call 

TextView text = (TextView) findViewById(R.id.textView1);
