Question

我正在使用此应用程序，我动态更改ListView大小，如下面的代码所示：

RelativeLayout.LayoutParams mParam = new   RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
sucs.setLayoutParams(myListView);

但是当我这样做时，ListView会出现在视图的顶部。有什么方法可以将它放在文本视图下面吗？

提前致谢！

编辑： 这是我的xml：

<TextView
    android:id="@+id/sucursales_empresa"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/direccion_empresa"
    android:background="@drawable/barra"
    android:text="@string/sucursales"
    android:visibility="gone" />

<ListView
    android:id="@+id/sucursalesEmpresaList"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/sucursales_empresa"
    android:cacheColorHint="#00000000"
    android:visibility="gone" />

Answer 1

你必须像这样添加listview LayoutParams规则..

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(
               LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);                
params1.addRule(RelativeLayout.BELOW, R.id.textview);
listview.setLayoutParams(params1);

Answer 2

试试这个

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
  ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, view.getId());

  view.setLayoutParams(params);
  ViewGroup parentView = (ViewGroup) findViewById(R.id.viewgroup);
  parentView.addView(mylsitview);
