将布局直接附加到listview底部
我的页面中有三个布局。两个线性布局，表示其中包含信息的2个条带，以及第三个线性布局中的列表视图。我成功地将其中一个线性布局连接到页面顶部，但我希望第二个linearlayout（底部控制条）附加到列表视图的底部，而不是屏幕底部。有人可以帮我解决这个问题......这是我的XML代码。

好的，所以我使用了两种不同的布局。一个用于页脚（当列表视图不填充整个屏幕时），一个用于底部视图（当列表视图大于屏幕时）。请记住，它们是两个不同的视图，但相同。这意味着您需要为每个项目提供不同的ID。
首先是截屏：
ListView不会填充整个屏幕
ListView会填充整个屏幕

可能的解决方案是将其放在PopulateList（）
中private void PopulateList() {
ArrayAdapter<BetParameters> adapter = new MyListAdapter();
ListView list = (ListView) findViewById(R.id.betslistview);
list.setAdapter(adapter);
final LinearLayout bottomView = (LinearLayout) findViewById(R.id.bottomView); // Bottom View
bottomView.setVisibility(View.GONE);
// FooterView when the list is smaller than the screen
final View footerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer, null, false);
// Runnable to check to see if the list is larger than the screen
Runnable fitsOnScreen = new Runnable() {
@Override
public void run() {
int last = list.getLastVisiblePosition();
if (last == list.getCount() - 1 && list.getChildAt(last).getBottom() <= list.getHeight()) { // List Not Full Screen
bottomView.setVisibility(View.GONE);
// Add the footer than reset the adapter to attack the footer
list.addFooterView(footerView);
} else {
// Does nothing other than make the bottom view visible.
bottomView.setVisibility(View.VISIBLE);
}
}
};
list .post(fitsOnScreen);
}

在第二个“线性布局”（底部控制栏）中，删除
android:layout_alignParentBottom="true"
并将其替换为
android:layout_below="@+id/betslistview"
在包含列表视图的第三个“线性布局”中，删除
android:layout_above="@id/bottom_control_bar"
