String variable and double variable of same name are different?
<p>How can I make it so when I refer to the display1 variable, I refer to double, and not the string? The program still refers to display1 as a string. I want the double.</p>

<pre><code>[code]
package rechee.cool;

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

public class HelloAndroidActivity extends Activity {
    /** Called when the activity is first created. */

    double counter1=0;
    double counter2=0;



     public EditText display;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        // Associate the button variable with the xml reference



        display= (EditText) findViewById(R.id.editText1);}
             //

             ////
