Trying to get my first android app up and running. It's a basic GCF
calculator, but I can't get it to run. Can anyone help me out?
package com.example.GCF;
import java.util.Arrays;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class GCF extends Activity {
private TextView mAnswer;
private EditText mA, mB;
private Button ok;
private String A, B;
private int iA, iB;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mA = (EditText) findViewById(R.id.entry);
mB = (EditText) findViewById(R.id.entry1);
ok = (Button) findViewById(R.id.ok);
mAnswer = (TextView) findViewById(R.id.answer1);
ok.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
A = mA.getText().toString();
B = mB.getText().toString();
}
});
// the String to int conversion happens here
iA = Integer.parseInt(A.trim());
iB = Integer.parseInt(B.trim());
while (iA != iB) {
int[] nums={ iA, iB, Math.abs(iA-iB) };
Arrays.sort(nums);
iA=nums[0];
iB=nums[1];
}
updateDisplay();
}
private void updateDisplay() {
mAnswer.setText(
new StringBuilder().append(iA));
}
}
