EditText get toString

This is my code but i can't fill my string with the value put in by the user.

I've tried a lot of solutions from other sites but it won't work.

package app.android.Mel

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;
import android.widget.Toast;

public class RedFlashlightActivity extends Activity {

private EditText text;
private TextView myRecord;
private Button myButton;

/** Called when the activity is first created. */
@Override

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    text = (EditText) findViewById(R.id.txtName);
    myButton = (Button) this.findViewById(R.id.myButton);
    myRecord = (TextView) findViewById(R.id.myRecord);
    final String rec = text.getText().toString();

    myButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            myRecord.setText(rec);
            Toast.makeText(RedFlashlightActivity.this,rec, Toast.LENGTH_SHORT).show();
        }

    });
}
}

Move the rec = text.getText().toString() into the OnClickListener event handler class. Then it should work. Otherwise it will take a null value, because you're using the String rec, which is constructed during the Activity creation phase.

The point is that rec is created once at the activity creation time and doesn't change ever after( it is final ). Just replace 

myRecord.setText(rec);

with 

myRecord.setText(text.getText().toString());

    myButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        String rec = text.getText().toString();
        myRecord.setText(rec);
        Toast.makeText(RedFlashlightActivity.this,rec, Toast.LENGTH_SHORT).show();
    }
});
