android - 带有滚动手势选项的自定义列表视图不单击

Question

我想制作列表视图，允许用户在不点击列表项的情况下选择选项，项目将通过类似于堆栈的滑动手势来选择。 在此处输入图像描述查看

如此图像列表中所示，将像滚动一样移动（通过滑动更改选项）以避免拿起手指

如果您在 android 中找到任何库或小部件或任何其他方式，请告诉我

Answer 1

创建 listview 或 recyclerview 并且必须在单击适配器中的项目时为背景项目（）创建选择器。

这是聚焦时编辑文本的示例选择器

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_enabled="true"
    android:state_focused="true">

    <shape android:shape="rectangle">
        <solid android:color="@color/white" />
        <corners android:radius="6dp" />
        <stroke android:width="1dp" android:color="@color/primary" />
    </shape>

</item>

<item android:state_enabled="true">
    <shape android:shape="rectangle">
        <solid android:color="@color/white" />
        <corners android:radius="6dp" />
        <stroke android:width="1dp" android:color="@color/gray" />
    </shape>

</item>

我找到了答案

在 activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
    android:layout_width="match_parent"
    >
<androidx.constraintlayout.motion.widget.MotionLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/motionLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layoutDescription="@xml/activity_main_scene"
    tools:showPaths="true">
<LinearLayout
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    >
    <TextView
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="Not Required"
        android:gravity="center"
        />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="not Recieved"
        android:gravity="center"
        />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="Partially Recieved"
        android:gravity="center"
        />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="Recieved"
        android:gravity="center"
        />
</LinearLayout>

<View
    android:id="@+id/view"
    android:layout_width="300dp"
    android:layout_height="50dp"
    android:background="@drawable/rectangle"
    />

</androidx.constraintlayout.motion.widget.MotionLayout>
</FrameLayout>

然后在

activity_main_scene.xml

            motion:touchAnchorId="@+id/button"
            motion:dragDirection="dragUp"
             />
    </Transition>
    <Transition
        motion:constraintSetStart="@+id/second"
        motion:constraintSetEnd="@+id/third"

在 java 或 kotline 中不需要额外的更改
