ViewGroup{TextView,...}.getMeasuredHeight gives wrong value is smaller than real height.
- by Dewr
ViewGroup(the ViewGroup is containing TextViews having long text except line-feed-character).getMeasuredHeight returns wrong value... that is smaller than real height.
how to get rid of this problem?
here is the java code:
;public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int count = listAdapter.getCount();
for (int i = 0; i < count; i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(View.MeasureSpec.AT_MOST, View.MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
;
and here is the list_item_comments.xml:;
{RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
}
{RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="8dip"
android:layout_marginRight="8dip"
}
{TextView
android:id="@+id/list_item_comments_nick"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"
style="@style/WhiteText"
/}
{TextView
android:id="@+id/list_item_comments_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textSize="16sp"
style="@style/WhiteText"
/}
{TextView
android:id="@+id/list_item_comments_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/list_item_comments_nick"
android:autoLink="all"
android:textSize="24sp"
style="@style/WhiteText"
/}
{/RelativeLayout}
{/RelativeLayout}
;
