您需要使用这里.

我开发了View来绘制类似Google pay的形状，该形状继承自FrameLayout.源代码可在其github存储库中使用(但尚未记录！).但是，将以下几行添加到您的应用级build.gradle文件中:

I have developed a View to draw a shape like google pay which inherits from FrameLayout. The source code is available on its github repository (but not documented yet!). However, add the following lines to your app level build.gradle file:

repositories {
    jcenter()
}

dependencies {
    implementation 'com.aminography:beziercurvebulgelayout:1.0.2'
}

然后您可以在xml布局文件中使用它，如下所示:

Then you can use it in xml layout files as following:

<com.aminography.view.BezierCurveBulgeLayout
    android:id="@+id/bulgeLayout"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    app:bulgeType="bulge"
    app:bulgeColor="@color/colorPrimary"
    app:curveWidth="32dp"
    app:flatWidth="56dp"
    app:flatHeight="24dp">

    <android.support.v7.widget.AppCompatImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@android:drawable/ic_menu_compass"/>

</com.aminography.view.BezierCurveBulgeLayout>

通过更改以下属性，可自定义形状和颜色以实现目标形状:

Its shape and color is customizable to achieve the target shape by changing below attributes:
