import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class Sayings extends Activity {

    private Button NewSayings;

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

        TextView mInfoTextView = (TextView) findViewById(R.id.saying); 
    }

    private class ButtonclickListener implements View.onclickListener { 
        int location; 

        public ButtonclickListener(int location) { 
            this.location = location; 
        } 

        public void onclick(View view) { 
              TextView mInfoTextView = null;
            mInfoTextView.setText(R.string.saying1);
        }
