Apps textView as output

hello all,

i want to make a textView1 that displays my random generated number when clicked on button1. so that i can build 5 questions with the if element.
the main question is how do i get my random generated number in a textView?

I know there is a big chance the random number gen won't work but I am new in the Android scripting and want to discover new things, if you know how to get a random number gen please tell me. but don't put to much effort.

Code:
package EasyApp.randomquestion;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
import android.widget.Button;



public class MainActivity extends Activity {

    TextView textView1;
    Button button1;
    
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    
    public final void RandomNumber (String args[], String RandomNumber){
        if (view == button1){
        RandomNumber =("random number:"+ 10 * Math.random());
        TextView text = (TextView) findViewById(R.id.textView1);
        text.setText(RandomNumber);
        }
    }

    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}
thanks in advance

Hi Olijf,

You'll want to attach an OnClickListener to button1. Try to Google for "android button setonclicklistener tutorial". I'm sure you will find something useful.
