问题：
我正在一个项目上，我需要以编程方式设置<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class Controller2 extends Controller
{
public function start($id){
return view('pages.exampleController2')->with('id',$id);
}
}
，但我没有得到，我总是得到一个endIconMode。在XML中，它可以完美工作，但在那种情况下，我需要以编程方式进行。

}
自定义属性：
<input.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp"
app:typeInput="password">
<input.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</input.TextInputLayout>
配置某些属性的类
private void initAttributesArray(TypedArray attrsArray) {
type = attrsArray.getString(R.styleable.TextInputLayout_typeInput);
}
我正在寻找一种在多个地方进行此工作的方法，但没有找到，因此建议使用stackoverflow。 谢谢大家！
