Hi,
I am a new comer to Android and need a help. Here is my question? How
to get to a new activity by clicking a button.
What is what I did.
In class CompantMenu, I have code like this
.........
.........
listButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
listCompany();
}
});
.........
.........
public void listCompany(){
Intent i = new Intent(this,ListCompany.class);
startActivity(i);
}
In class ListCompany, I have code like this,
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.list_company);
}
Node:list_company.xml is availabe and classes ListCompany CompantMenu
are in AndroidManifest.xml.
When I lick listButton, I did not get page defined by list_company,
instead, I got java.long.NullPointerException.
How solve this issue?
Thanks
Billsen
