滚动活动的布局问题

Question

我正在开发一个Android项目，我添加了一个滚动活动。屏幕下端的一部分采用背景颜色，使一切看起来都不整洁。This is how it looks。我该如何解决？我希望中间部分延伸到屏幕的底部，我尝试了一切改变高度，与父母匹配。什么都没有用。非常感谢你的帮助！谢谢。代码如下。

Answer 1

您可以使用listview获取所需的布局。由于listview本身是可滚动的，因此无需添加单独的scrollview。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/backgnd"
android:layout_marginRight="24dp"
android:layout_marginLeft="24dp">
       <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />
</LinearLayout>

然后为列表视图中的每个项目定义另一个布局，例如item.xml为

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        android:baselineAligned="false">
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_margin="@dimen/text_margin"
            android:layout_weight="1"
            android:text="This is a generic message"
            android:layout_gravity="center_horizontal" />
        <Button
            android:layout_width="48dp"
            android:id="@+id/button22"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:background="@drawable/play" />
</LinearLayout>

使用适配器在列表视图中显示内容。在适配器的getView（）函数中，您可以使用item.xml布局来扩展视图。例如，

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  View rowView = mInflater.inflate(R.layout.item, parent, false);
  return rowView;
}

这是为了给你一个想法。请将其更改为您的项目。
