Hide an element of ListView's item depending on Cursor's column value
I have a child of CursorAdapter class, and a ListView which every item has two TextViews. One holding a text, and another holding a number.
Text is from one Cursor column, and number from another. I want to hide number if it is equals to 0.
My View for list item is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<TextView
android:background="@drawable/task_count_indicator"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_gravity="center_vertical"
android:textColor="@color/white"
android:id="@+id/txtTaskCount" />
<TextView
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:ellipsize="marquee"
android:textSize="18sp"
android:layout_alignParentLeft="true"
android:layout_gravity="center_vertical"
android:id="@+id/placeItemName"/>
</RelativeLayout>
My adapter code is:
@Override
public View newView(Context context, Cursor cursor, ViewGroup viewGroup) {
return LayoutInflater.from(context).inflate(R.layout.places_list_item, viewGroup, false);
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
int taskCount = cursor.get...// get to know it...
TextView name = (TextView) view.findViewById(R.id.placeItemName);
name.setText(
cursor.getString(
cursor.getColumnIndexOrThrow(...)));
TextView count = (TextView)view.findViewById(R.id.txtTaskCount);
if(taskCount > 0)
count.setText(Integer.toString(taskCount));
else
count.setVisibility(View.GONE);
}
The problem is what sometimes every view that holds a number is drawn hidden, or with incorrect value (text content is always correct). I log the taskCount
value - it is always correct.
开发者_运维技巧Also i noticed, if i comment an if statement and assign text to count
always, like this:
//if(taskCount > 0)
count.setText(Integer.toString(taskCount));
//else
//count.setVisibility(View.GONE);
the problem isn't reproducing.
I think your problem is related to the case where taskCound>0
You should need to specify count.setVisibility(View.Visible)
since the view is being reused. So be sure to define your values for each case.
Hope that helps
