Java 选择android时设置选项卡图标的背景形状

我不熟悉

android

和

java

。我正在我的应用程序中使用

选项卡布局

。它看起来像下面

XML格式的我的选项卡布局代码：

<com.google.android.material.tabs.TabLayout
        android:id="@+id/tabs"
        android:background="#F7F7F7"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable"
        app:tabBackground="@drawable/tab_selector"
        app:tabTextColor="@color/tab_text_unselected_color"
        app:tabSelectedTextColor="@color/tab_text_selected_color"
        app:tabIndicator="@drawable/custom_tab_indicator"
        app:tabIndicatorColor="@color/tab_indicator_color"
        app:tabIndicatorFullWidth="false"
        app:tabIndicatorHeight="5dp"
        app:tabTextAppearance="@style/MineCustomTabText"
        app:tabIconTint="@color/custom_tab_icon_color_setter"
        tools:ignore="MissingConstraints">

我想添加一个背景圆形状的矢量图标时，如下图选择

这是圆形：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@color/tab_selected_color"
        android:state_selected="true"/>
    <item
        android:drawable="@color/tab_unselected_color"
        android:state_selected="false"/>
</selector>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/colorAccent" />
    <corners
        android:bottomLeftRadius="0dp"
        android:bottomRightRadius="0dp"
        android:topLeftRadius="10dp"
        android:topRightRadius="10dp" />
</shape>

<style name="MineCustomTabText" parent="TextAppearance.Design.Tab">
        <item name="android:textSize">10sp</item>
</style>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="@color/colorPrimary"/>

</shape>

我不知道如何做到这一点。请帮我解决一些问题

我试图通过向图标添加背景来修改此代码

自定义选项卡图标颜色设置器：-

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:background="@drawable/cirle_shape" android:color="@color/tab_icon_selected_color"  android:state_selected="true"/>
    <item android:color="@color/tab_icon_unselected_color"/>
</selector>

但什么都不会改变。请帮助我找到一些解决方案来实现这一点

只需将此背景添加到您的视图中即可

android:background=？android:attr/actionBarItemBackground

无需创建任何形状res文件。将此背景添加到您想要显示背景的视图。

感谢您的回复。。。没有变化。。。它不起作用。。。
