java - 自定义复合 View 抛出 "Error inflating class"

Question

我制作了一个自定义复合 View :

linkui.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="5dp">

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Some Text" />

</LinearLayout>

并将其放入 Activity.xml 中:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <!-- ....Other components -->

    <com.button.LinkUI
        android:id="@+id/link"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</RelativeLayout>

这是 View 的java类，它有一个setter setText:

public class LinkUI extends LinearLayout {

    private TextView textView;

    public LinkUI(Context context) {
        super(context);
        init();
    }

    public LinkUI(Context context, AttributeSet attrs) {
        super(context,attrs);
        init();
    }
    public LinkUI(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public void setText(String str){
        this.textView.setText(str);
    }

    private void init() {
        inflate(getContext(),R.layout.linkui,this); <---
        this.textView = (TextView)findViewById(R.id.text);    

    }

}

根据调试控制台， View 从第二个构造函数 public LinkUI(Context context, AttributeSet attrs) 开始，然后在 View 膨胀时在 init() 处崩溃布局 R.layout.linkui，谁能告诉我膨胀 xml 有什么问题吗？

错误:

我的sdk版本:

编译SdkVersion 25buildTools版本“25.0.0”

不要在构造函数中调用 initUi()，而在 onFinishInflate() 中调用。
