2. I have done some tests with list views, but is a view, that replace the xml view, i want it inside my xml,,
thanks a lot!
Yes, of course, you can do that
1) you need to have listholder.xml
here, you can scratch anything in you layout view, either imageview, textview..etc. just don't forget to add ListView inside it. for example:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/head_logo_bg">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background_label">
<TextView
android:id="@+id/city_txt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_gravity="center"
android:text="Sydney"
android:textStyle="bold"
android:textSize="17sp"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="40sp">
<ListView
android:id="@android:id/list"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_centerVertical="true"
android:scrollingCache="false"/>
</LinearLayout>
2) For custom your own list item, you have to create listitem.xml
i.e.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listitemone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10sp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:orientation="vertical">
<ImageView android:id="@+id/user_image"
android:layout_width="80px" android:layout_height="80px"
android:layout_alignParentLeft="true"
android:layout_marginRight="5px"
android:src="@drawable/icon"
/>
</LinearLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5sp"
android:orientation="vertical">
<TextView
android:id="@+id/date_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/date"
android:textStyle="bold"
android:textSize="16sp" />
<TextView
android:id="@+id/date_value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignBaseline="@id/date_label"
android:layout_marginRight="20sp"
android:textColor="#FFF"
android:text="MM/dd/YYYY"
android:textStyle="bold"
android:textSize="16sp" />
</RelativeLayout>
</LinerLayout>
3) create customAdapter in your activity, it would look like this;
public class MyListActivity extends ListActivity {
private ArrayList<Yourdata> yourdata = new ArrayList<Youdata>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listholder);
// yourdata might be array, arraylist etc.
MyCustomAdapter listadapter = new MyCustomAdapter(this, R.layout.listitem, yourdata);
setListAdapter(listadapter);
}
private class MyCustomAdapter extends ArrayAdapter<Yourdata>{
//this case, i use Yourdata as type
private ArrayList<Yourdata> items;
public PreviousAdapter(Context context, int textViewResourceId,
ArrayList<Yourdata> items) {
super(context, textViewResourceId, items);
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if(v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
}
Yourdata yt = items.get(position);
if(yt != null){
// Don't forget to use v.findView...., otherwise, it might force close when run app.
TextView dateStr = (TextView)v.findViewById(R.id.date_value);
dateStr.setText(yt.getDate());
}
return v;
}
}
}
P.S. the above code might not exactly right... just give you an idea :)
