我想shape用它bottom line和text它内部构建它我有点困惑如何实现这个我厌倦了一些代码但没有得到必需的东西。

期望的结果

到目前为止，我已经尝试过这段代码

形状.xml

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <!-- Colored rectangle-->
    <item>
        <shape android:shape="rectangle">
            <size
                android:width="100dp"
                android:height="40dp" />
            <solid android:color="#13a89e" />
        </shape>
    </item>


    <!-- This rectangle for the right side -->
    <!-- Their color should be the same as layout's background -->
    <item
        android:right="-100dp"
        android:left="100dp"
        android:top="-100dp"
        android:bottom="-100dp">
        <rotate
            android:fromDegrees="45">
            <shape android:shape="rectangle">
                <solid android:color="#ffffff" />
            </shape>
        </rotate>
    </item>

</layer-list>

它提供以下结果。我的尝试

我还需要这个形状下面的黄线。

感谢帮助。

这是您的 XML：

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<!-- Colored rectangle-->
<item>
    <shape android:shape="rectangle">
        <padding android:top="35dp"/>
        <size android:width="200dp" android:height="40dp" />
        <solid android:color="#13a89e" />
    </shape>
</item>
<!-- Darker colored line-->
<item>
    <shape android:shape="line">
        <size android:width="100dp"/>
        <stroke android:width="4dp" android:color="#123456" />
    </shape>
</item>


<!-- This rectangle for the right side -->
<!-- Their color should be the same as layout's background -->
<item
    android:right="-200dp"
    android:left="200dp"
    android:top="-200dp"
    android:bottom="-200dp">
    <rotate android:fromDegrees="45">
        <shape android:shape="rectangle">
           <padding android:top="-35dp"/>
           <solid android:color="#ffffff" />
        </shape>
    </rotate>
</item>
<!-- This rectangle for the left side -->
<item
    android:right="200dp"
    android:left="-200dp"
    android:top="-200dp"
    android:bottom="-200dp">
    <rotate android:fromDegrees="-45">
        <shape android:shape="rectangle">
            <padding android:top="-35dp"/>
            <solid android:color="#ffffff" />
        </shape>
    </rotate>
</item>

这就是它呈现的内容：

结果

这是我的TextViewXML：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="io.kalabalik.tilted.MainActivity">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/box"
    android:text="Your Text!"
    android:textColor="#000000"
    android:gravity="center_horizontal|bottom"
    android:paddingBottom="10dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

我强烈建议创建自定义文本视图，这样它会更加灵活和可控。您需要创建路径对象，并使用该对象定义视图角。如果您想以文本形式查看，则需要覆盖onDraw (Canvas canvas) 函数，您将调用 canvas.draw(path, paint) 方法。如果您不仅需要文本字段，您应该覆盖任何视图组类，但对于视图组，您应该覆盖onDispatchDraw函数来做到这一点。

你可以像下面的例子一样创建你的形状

    // you can define all points
    Point topLeft = new Point(0,0);
    Point topRight = new Point(getWidth(),0); // your view width
    //... 

    //cover your corner points
    Path path = new Path();
    path.moveTo(topLeft.x, topLeft.y);
    path.lineTo(topRight.x, topRight.y);
    path.lineTo(bottomRight.x, bottomRight.y);
    path.lineTo(shapeBottomRight.x, shapeBottomRight.y);
    path.lineTo(shapeTop.x, shapeTop.y);
    path.lineTo(shapeBottomLeft.x, shapeBottomLeft.y);
    path.lineTo(bottomLeft.x, bottomLeft.y);
    path.lineTo(topLeft.x, topLeft.y);

    canvas.draw(path, paint);

这篇文章在创建梯形视图方面帮助了我很多https://arkapp.medium.com/trapezium-view-for-android-584799c7e849

<com.arkapp.trapeziumview.TrapeziumCustomView
        android:id="@+id/trapeziumCustomView"
        android:layout_width="match_parent"
        android:layout_height="350dp"
        android:layout_margin="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:shapeColor="@color/teal_200"
        app:edgeRadius="18"
        app:slopeLength="88"
        app:slopeType="bottomRight" />

借助这个，我能够创建一个自定义视图，其中一个边缘作为斜率
