我在滚动视图里面有5个列表视图..列表视图根据具体情况显示..主要问题是getview方法调用两次..例如sizeof数据1表示，getview方法调用2次..所以附加view get created..i设置listview的高度来填充父级而不是work ..i给我的adaper类和视图
@Override

if(boxx.equalsIgnoreCase("checkbox")) {
// String customName = getItem(position);

这就是我设置适配器的方式
if(isDatecustom)
{
date_list.setVisibility(View.VISIBLE);
RelativeLayout date_list_lay = (RelativeLayout) findViewById(R.id.date_list_lay);
date_list_lay.setVisibility(View.VISIBLE);
CustomCheckboxAdapter checkboxAdapter = new CustomCheckboxAdapter(ProductDetailView.this, datevalues,0,"date");
date_list.setAdapter(checkboxAdapter);
setListViewHeightBasedOnChildren(date_list);
}
<RelativeLayout
android:id="@+id/drop_down_list_lay"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:visibility="gone"
android:layout_marginTop="20dp"
android:gravity="center" >
<ListView
android:id="@+id/drop_down_list"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:divider="@null"
android:dividerHeight="0dp"
android:visibility="gone" />
</RelativeLayout>
@SuppressLint("NewApi")
public void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter myListAdapter = listView.getAdapter();
if (myListAdapter == null) {
// do nothing return null
return;
}
// set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, listView);
if (listItem instanceof ViewGroup)
listItem.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
WindowManager wm = (WindowManager) baseactivity.this
.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
int screenWidth = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
int listViewWidth = screenWidth - 10 - 10;
int widthSpec = MeasureSpec.makeMeasureSpec(listViewWidth,
MeasureSpec.AT_MOST);
listItem.measure(widthSpec, 0);
totalHeight += listItem.getMeasuredHeight();
}
// setting listview item in adapter
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight
+ (listView.getDividerHeight() * (myListAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
