UniComponent的构造函数有两个，一个4个参数的，一个3个参数的。你只实现了4个参数的构造函数，官方的TextView实现的3个参数的构造函数。估计报错的时候调用的是3个参数的，你加个3个参数的构造函数应该就可以了

报错的代码
package com.uninative.mycomponent;
import android.content.Context;
import android.support.annotation.NonNull;
import android.widget.Button;
import io.dcloud.feature.uniapp.UniSDKInstance;
import io.dcloud.feature.uniapp.ui.action.AbsComponentData;
import io.dcloud.feature.uniapp.ui.component.AbsVContainer;
import io.dcloud.feature.uniapp.ui.component.UniComponent;
public class MyButton extends UniComponent<Button> {
public MyButton(UniSDKInstance instance, AbsVContainer parent, int type, AbsComponentData componentData) {
super(instance, parent, type, componentData);
}
@Override
protected Button initComponentHostView(@NonNull Context context) {
Button btn=new Button(context);
btn.setText("哈哈");
return btn;
}
}

确实是构造方法的问题，重写一下构造方法就可以了
