Hi all,
first of all, let me introduce my self. My name is Teguh, currently
I'm new to android and trying to develop an application in android.
At the moment I found an issue while using a listener..
code issue : (this code will generate an error when launching the
application)
public class Sudoku extends Activity implements OnClickListener{
private static final String TAG = "Sudoku";
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Set up click listeners for all the buttons
View continueButton = findViewById(R.id.continue_button);
continueButton.setOnClickListener(this);
View newButton = findViewById(R.id.new_button);
newButton.setOnClickListener(this);
View aboutButton = findViewById(R.id.about_button);
aboutButton.setOnClickListener(this);
View exitButton = findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.about_button:
Intent i = new Intent(this, About.class);
startActivity(i);
break;
}
}
}
code OK: (i removed the listener, and running successfully when
initialize)
public class Sudoku extends Activity implements OnClickListener{
private static final String TAG = "Sudoku";
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.about_button:
Intent i = new Intent(this, About.class);
startActivity(i);
break;
}
}
}
-----------------------------
Does anybody know what was happened to the code?
the error comes in initialize mode of this application.
Thank you very much for all of you attention.
