Can You help me please. I need to change background color of my list view item which is selected manually by setSelection(int pos) function and I need to stay with new color until new setSelection call. I have read some topics of how to do this, but I still have no succes. Thanks!
I've managed to accomplish that by making several selectors for the different states
first put this in your listview
android:listSelector="@drawable/list_selector"
Then create xml files in drawable to control the diferent states
@drawable/list_selector
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/list_item_bg_normal" android:state_activated="false"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_pressed="true"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_activated="true"/>
</selector>
@drawable/list_item_bg_normal
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="@color/list_background"
android:endColor="@color/list_background"
android:angle="90" />
</shape>
@drawable/list_item_bg_pressed
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="@color/list_background_pressed"
android:endColor="@color/list_background_pressed"
android:angle="90" />
</shape>
In your ListView Selection
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,long arg3) {
view.setSelected(true);
...
}
}
Don't forget to add list_background_pressed and list_background to your values/color.xml or just set the color manually in each file.
And I Believe that when you use setSelection(int pos) that will automatically uset the layout you've set as selectected.
Hope it helps.
