android.view.InflateException：XML佈局中的二進制XML文件行

這裏是我的代碼。當我膨脹顯示異常的視圖名爲android.view.InflateException：我的MainActivity類中的二進制XML行＃8。也導致應用程序崩潰，如果在代碼中的任何過錯？。請幫我android.view.InflateException：XML佈局中的二進制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"

    <com.example.newscratch.PaintView

請發佈異常堆棧跟蹤，包括嵌套的「異常引起的」。 – laalto

您是否爲您正在嘗試開發的應用程序添加了適當的庫，如果是，請嘗試清理您的項目或重新啓動eclipse。或者如果沒有，然後檢查兩次並添加它。 – InnocentKiller

您必須在PaintView類中定義兩個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); 
    }

感謝您的回覆。其工作 –

沒有堆棧跟蹤，這是不容易......

乍一看：適當的構造函數中缺少您的PaintView類。

添加一個構造函數與此簽名：

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

我想你忘了貫徹落實「XML構造」。您應該添加：

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

請參閱documentation瞭解更多信息。
