android.view.InflateException：XML布局中的二进制XML文件行

这里是我的代码。当我膨胀显示异常的视图名为android.view.InflateException：我的MainActivity类中的二进制XML行＃8。也导致应用程序崩溃，如果在代码中的任何过错？。请帮我android.view.InflateException：XML布局中的二进制XML文件行

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:background="@drawable/ic_launcher"> 

    <com.example.newscratch.PaintView 
     android:layout_gravity="center"

请发布异常堆栈跟踪，包括嵌套的“异常引起的”。 – laalto

您是否为您正在尝试开发的应用程序添加了适当的库，如果是，请尝试清理您的项目或重新启动eclipse。或者如果没有，然后检查两次并添加它。 – InnocentKiller

您必须在PaintView类中定义两个constrcutors ...

public PaintView(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
     initView(context); 
    } 

    public PaintView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     initView(context); 
    }

感谢您的回复。其工作 –

没有堆栈跟踪，这是不容易......

乍一看：适当的构造函数中缺少您的PaintView类。

添加一个构造函数与此签名：

public PaintView(Context context, AttributeSet attrs, int defStyle){ 
    super(...); 
    ... 
}

我想你忘了贯彻落实“XML构造”。您应该添加：

public PaintView((Context context, AttributeSet attrs) { 
    super(context, attrs); 
    initView(context); 
}

请参阅documentation了解更多信息。
