Good afternoon.
I have an app that consumes webservices (that part is already finished), but now I require that this app works without internet access, I have created my bd and I already have saved data.
My question is if I can use a Layout for 2 different activities: one for when I'm connected to wifi and the other activity when I'm not using wifi and work locally.
Of course you can Hugo, the way to load the layout in your Activity as you know is through the method setContentView () to inflate the layout:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_layout);
}
You can reuse the same layout in several Activities, even validate in the same Activity to load one or the other layout.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(existeWIFI){
setContentView(R.layout.my_layout);
}else{
setContentView(R.layout.my_layout_nowifi);
}
}
You can use the SetConentView() method, I'll give you an example:
public class PrincipalActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
The line setContentView(R.layout.main); indicates that there is a static class called R.layout , and that within that class there is an integer constant called main , which points to a view defined by a resource file layout XML
