我正在尝试创建我创建的自定义 AppCompactEditText。我还创建了一个示例应用程序来测试我的自定义组件。但是，当我从示例应用程序的 xml 调用/输入我的自定义编辑文本时，它崩溃并给出错误java.lang.RuntimeException: Unable to start activity ComponentInfo
这是我的代码
class InputFields: AppCompatEditText{
private var mContext: Context
private var mAttrs: AttributeSet?
private var mDefStyleAttr: Int? = 0
constructor(context: Context) : super(context) {
mContext = context
mAttrs = null
init()
}
constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
mContext = context
mAttrs = attrs
init()
}
constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int) : super(context, attrs, defStyleAttr) {
mContext = context
mAttrs = attrs
mDefStyleAttr = defStyleAttr
init()
}
private fun init(){
// this function initializes all the attributes
// however when I debug it , it doesn't reach this block of code at all.
}
}
我在这样的示例应用程序中调用它
<com.sample.inputfields.InputFields //line #26 ..The Error occurs on this line
android:id="@+id/input_field"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
/>
这是我得到的错误

我也以正确的方式导入了自定义组件/模块。有人可以帮我弄清楚我做错了什么。提前致谢。
