    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 (Text):
    1.  
    2. package EasyApp.randomquestion;
    3.  
    4. import android.os.Bundle;
    5. import android.app.Activity;
    6. import android.view.Menu;
    7. import android.widget.TextView;
    8. import android.widget.Button;
    9.  
    10.  
    11.  
    12. public class MainActivity extends Activity {
    13.  
    14.     TextView textView1;
    15.     Button button1;
    16.    
    17.    
    18.     @Override
    19.     public void onCreate(Bundle savedInstanceState) {
    20.         super.onCreate(savedInstanceState);
    21.         setContentView(R.layout.activity_main);
    22.     }
    23.    
    24.     public final void RandomNumber (String args[], String RandomNumber){
    25.         if (view == button1){
    26.         RandomNumber =("random number:"+ 10 * Math.random());
    27.         TextView text = (TextView) findViewById(R.id.textView1);
    28.         text.setText(RandomNumber);
    29.         }
    30.     }
    31.  
    32.    
    33.  
    34.     @Override
    35.     public boolean onCreateOptionsMenu(Menu menu) {
    36.         getMenuInflater().inflate(R.menu.activity_main, menu);
    37.         return true;
    38.     }
    39. }
    40.  
    41.  
    42.  
    thanks in advance
    - Olijf

    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.
