我有水平布局，通过在线性布局上添加图像来动态添加图像视图。并且所有水平视图都垂直添加scorllview
||||||| when touch then change colored to grayscred this view(view added images here)
|||||||
|||||||
|||||||
现在，如果我在触摸水平scoll视图，我想改变defualt图像被着色为灰度（黑色和白色）。中 ontouch on horizontal scorllview put但无法重新调整。而不是改变效果。我做了什么。
我的主要意图是： 当Horizontall滚动图像时，只有窗口视图（触摸视图）灰度级保持前一阶段（彩色）。
这是我的代码适用于图像，但我想在水平视图上。

您可以在xml文件中添加布局背景，并为此背景设置自定义布局
android:background="@drawable/custombackground"
custombackground.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_window_focused="false"
android:state_enabled="true"
android:color="your color code" />
<item
android:state_window_focused="false"
android:state_enabled="false"
android:color="your color code" />
<item
android:state_pressed="true"
android:color="your color code" />
<item
android:state_enabled="true"
android:state_focused="true"
android:color = "#00000000"/>
<item
android:state_enabled="true"
android:color="your color code" />
<item
android:state_focused="true"
android:color="your color code" />
<item
android:color="your color code" />
</selector>
希望它会对你有所帮助:)。

基本上，您需要在触摸时更改imageview的颜色，因为您必须在case MotionEvent.ACTION_DOWN:中实现颜色更改代码
例如，变化的颜色是浅灰色
所以代码将是
v.setBackgroundColor(Color.LTGRAY);
您可以根据您的要求更改颜色
之后，将以下代码放入case MotionEvent.ACTION_UP:
将颜色更改为默认值，即transperent
v.setBackgroundColor(Color.TRANSPARENT);
