Hi, I'm having similar problems as stated above.
My onClick() method is created in one of my Button setOnClickListener
initilizations. Whenever I click my button, a force stop occurs. Here
is my code:
package com.nrg.droidcraft;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainAct extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initButtons();
}
private void initButtons(){
final Button zergbutton = (Button)
findViewById(R.id.zergbutton);
zergbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
Intent zerg = new Intent(this,
ZergScreen.class);
startActivity(zerg);
}
});
final Button terranbutton = (Button)
findViewById(R.id.terranbutton);
final Button protossbutton = (Button)
findViewById(R.id.protossbutton);
}
}
The error it is giving me is that the this is pointing to the
View.OnClickListener(), not the Context. Could someone help me
correctly implement this method? Thank you.
