Programming an Android Button to update EditText views
- by bergler77
Ok guys, I have a button in android that i'm trying to use to update 8 EditText Views with different random numbers. Everything works up until I click the button. It appears I am missing a resource according to the debugger, but I'm not sure what. I've tried several different ways of implementing the button. Here is what I have after looking at several posts.
import java.util.Random;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MyCharNewChar extends MyCharActivity {
private OnClickListener randomButtonListener = new OnClickListener(){
public void onClick(View v) {
//Button creates a set of random numbers and updates the values
//of the EditText views.
Random rand = new Random();
int STR = 1 + rand.nextInt(12);
int AGI = 1 + rand.nextInt(12);
int DEX = 1 + rand.nextInt(12);
int WIS = 1 + rand.nextInt(12);
int INT = 1 + rand.nextInt(12);
int CON = 1 + rand.nextInt(12);
int HP = 1 + rand.nextInt(20);
int AC = 1 + rand.nextInt(6);
EditText str = (EditText) findViewById(R.id.str);
str.setText(STR);
EditText agi = (EditText) findViewById(R.id.agi);
agi.setText(AGI);
EditText dex = (EditText) findViewById(R.id.dex);
dex.setText(DEX);
EditText wis = (EditText) findViewById(R.id.wis);
wis.setText(WIS);
EditText intel = (EditText) findViewById(R.id.intel);
intel.setText(INT);
EditText con = (EditText) findViewById(R.id.con);
con.setText(CON);
EditText hp = (EditText) findViewById(R.id.baseHP);
hp.setText(HP);
EditText ac = (EditText) findViewById(R.id.baseAC);
ac.setText(AC);
}
};
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.newchar);
Button randomButton = (Button) findViewById(R.id.randomButton);
randomButton.setOnClickListener(randomButtonListener);
}
}
Here is the xml:

I have also tried setting the onClick in xml to setup a specific onClick method. Still the same error so I must have a problem elsewhere. Any suggestions would be great!
