解决方案

我有同样困惑的问题。要修复它自定义视图应该提供一个构造函数有两个参数：上下文和作为的AttributeSet谏here.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res/com.org.BatteryManager"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical"
  >
<com.org.BatteryManager.BatteryView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:textColor="#ffffffff"
/>
</LinearLayout>

解决方案

I had the same confusing problem. To fix it your custom view should provide a constructor with two arguments: Context and AttributeSet as adviced here.
