上述代码给出的输出如下所示

由于存在scrollView，标题布局变得不可见。我的代码有什么问题？我应该怎么做才能得到一个带有固定页眉和页脚的可滚动内容的布局？plz帮助。

对父容器使用线性布局而不是相对布局。将LinearLayout的方向设置为垂直，并将ScrollView的LayoutWeight设置为1。

对父容器使用LinearLayout而不是RelativeLayout。将LinearLayout的方向设置为垂直，并将ScrollView的LayoutWeight设置为1。

1-将ScrollView的高度和宽度设置为与父视图匹配

2-将Scrollview的顶部和底部填充设置为与顶部和底部栏高度相等

3-将顶部栏的对齐设置为alignparenttop

4-将底部栏的对齐方式设置为alignparentbottom

注意：如果你想要一个好的兼容库用于操作栏，请考虑使用.< /P> < P > 1 -将滚动视图的高度和宽度设置为MatHelPrime.< /P> 2-将Scrollview的顶部和底部填充设置为与顶部和底部栏高度相等

3-将顶部栏的对齐设置为alignparenttop

4-将底部栏的对齐方式设置为alignparentbottom

在上面的代码中，我通过简单地重新排列向body布局添加内部布局的顺序，最终得到了所需的布局，顺序如下

objRLBody.addView(objRLScrollView);
objRLBody.addView(objRLActionBar);
objRLBody.addView(objRLSelectedActionBar);
objRLBody.addView(objRLFooter);
还需要设置scrollview填充，如果我们没有将填充设置为scrollview（页眉布局宽度为顶部填充，页脚宽度为底部填充），则组件视图可能会被页眉或页脚布局阻止。

objRLBody.addView(objRLFooter);
