我有一个android布局，其中有一个带有许多元素的scrollView。在scrollView的底部，我有一个listView，然后由适配器填充。
我遇到的问题是，android是排除listView从scrollView作为scrollView已经有一个可滚动的功能。我希望listView和内容一样长，并且主滚动视图是可滚动的。
我怎样才能实现这种行为呢?
这是我的主要布局:
<ScrollView
android:id="@+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="2"
android:fillViewport="true"
android:gravity="top" >
<LinearLayout
android:id="@+id/foodItemActvity_linearLayout_fragments"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
然后，我以编程方式将我的组件添加到linearlayour的id: foodItemActvity_linearLayout_fragments。下面是加载到线性布局中的一个视图。就是这个给我的卷轴带来了麻烦。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/fragment_dds_review_textView_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Reviews:"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ListView
android:id="@+id/fragment_dds_review_listView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
</LinearLayout>
我的适配器然后填充这个列表视图。
当我点击主scrollView时，这是一个来自android层级查看器的图像:
如您所见，它排除了评论列表视图。
我应该能够向下滚动页面，看到8个评论，但它只显示了这3个，我可以滚动评论所在的一小部分。我想要一个全局页面滚动
这对我有用(link1, link2):
You Create Custom ListView Which is non Scrollable
public class NonScrollListView extends ListView {
public NonScrollListView(Context context) {
super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = View.MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, View.MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
}
In Your Layout File
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- com.Example Changed with your Package name -->
<com.thedeveloperworldisyours.view.NonScrollListView
android:id="@+id/lv_nonscroll_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</com.thedeveloperworldisyours.view.NonScrollListView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/lv_nonscroll_list" >
<!-- Your another layout in scroll view -->
</RelativeLayout>
</RelativeLayout>
</ScrollView>
Create a object of your customListview instead of ListView like :
NonScrollListView non_scroll_list = (NonScrollListView) findViewById(R.id.lv_nonscroll_list);
I'll leave it here in case anyone will face the same issue. I had to put a ListView inside a ScrollView. ListView with header was not an option by a number of reasons. Neither was an option to use LinearLayout instead of ListView. So I followed the accepted solution, but it didn't work because items in the list had complex layout with multiple rows and each listview item was of variable height. Height was measured not properly. The solution was to measure each item inside ListView Adapter's getView() method.
@Override
public View getView(int position, View view, ViewGroup parent) {
ViewHolder holder;
if (view == null) {
. . .
view.setTag(holder);
} else holder = (ViewHolder)view.getTag();
. . .
// measure ListView item (to solve 'ListView inside ScrollView' problem)
view.measure(View.MeasureSpec.makeMeasureSpec(
View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
return view;
}
