Use This for doing your work
list.setOnItemClickListener(new AdapterView.onItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
Intent appInfo = new Intent(YourActivity.this, ApkInfoActivity.class);
startActivity(appInfo);
}
});
public class MenuYangu extends ListActivity {
String classes[] = { "Quiz Trivia", "Sign A New User", "Friend List",
"Download A File", "Upload A File", "Select Pdf files", "Memory Game",
"Dzidza Maths", "Write Exam" };
@Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menuone.this,
android.R.layout.simple_list_item_1, classes));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
if (position == 0) {
Intent intent = new Intent(this, QuizActivity.class);
startActivity(intent);
}
else if (position == 1) {
Intent intent = new Intent(this, SignUp.class);
startActivity(intent);
}
else if (position == 2) {
Intent intent = new Intent(this, FriendList.class);
startActivity(intent);
}
}
}
}
You need to use Intent, You can also pass the clicked listview item data to your new activity.
String classes[] = { "Quiz Trivia", "Sign A New User", "Friend List",
"Download A File", "Upload A File", "Select Pdf files", "Memory Game",
"Dzidza Maths", "Write Exam" };
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getApplicationContext(),ApkInfoActivity.class);
intent.putExtra("name",classes[i]);
startActivity(intent);
}
});
}
