Fix background image on Scrollview Android
提问by Mohammad Farahi
When I use Scrollview in my codes my background image stretches and scrolls with buttons. I want just buttons scroll, not the background. I have attached a related image that you can figure this out. Here is the XML file:
当我在我的代码中使用 Scrollview 时，我的背景图像会随着按钮拉伸和滚动。我只想滚动按钮，而不是背景。我附上了一张相关的图片，你可以弄清楚这一点。这是 XML 文件：

This thing worked fine for me.
这件事对我来说很好用。
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/gearImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:clickable="true"

</ScrollView>

make 1 Linearlayout at root instead of scrollview and use android:background="@drawable/back"to that layout as
在 root 处创建 1 Linearlayout 而不是 scrollview 并将use android:background="@drawable/back"该布局设为

Here I am assuming that your @drawable/backis your given image background
在这里，我假设您@drawable/back是给定的图像背景
回答by Raanan
Set the background image on the ScrollView and add Padding to the ScrollView or Margins to the Linearlayout.
在 ScrollView 上设置背景图像，并将 Padding 添加到 ScrollView 或将 Margins 添加到 Linearlayout。

This worked for me. The image was resized automatically and filled the entire background (Adjusted on width and cropped on height.)
这对我有用。图像自动调整大小并填充整个背景（调整宽度并裁剪高度。）

android:layout_width="fill_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"

<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:src="@drawable/app_back_image" />
</RelativeLayout>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:isScrollContainer="true">
...

As Raanan said, set the background image on the ScrollView, but to prevent backround from streching on different screen size, you can add gravity to it.
正如 Raanan 所说，在 ScrollView 上设置背景图像，但为了防止背景在不同的屏幕尺寸上拉伸，您可以为其添加重力。
<?xml version="1.0" encoding="utf-8"?>
<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/back"
android:gravity="top" />
