Android：膨胀异常

我是新来的android和我想在我的android应用程序的许多活动中膨胀一个常见的页脚。这个页脚中的一些按钮需要在整个应用程序中工作。这里是我的代码：Android：膨胀异常

BottomBar类：

package com.traderscockpit; 

import android.content.Intent; 
import android.util.AttributeSet; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.widget.RelativeLayout; 

public class BottomBar extends RelativeLayout { 
    private LayoutInflater inflater; 

    public BottomBar(Context context, AttributeSet attr) { 
     super(context, attr); 
     // TODO Auto-generated constructor stub 
     inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     inflater.inflate(R.layout.bottom_bar, this, true); 
    } 


}

bottom_bar.xml：

<?xml version="1.0" encoding="utf-8"?> 
<merge xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 
    <Button 
     android:id="@+id/homeButton" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Home"   
     android:layout_weight="1" 
     android:onClick="HomeClick" 
     /> 

    <Button 
     android:layout_weight="1" 
     android:id="@+id/logoutButton" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Logout" 
     android:onClick="HomeClick" 
     />  
</merge>

这是我如何合并到活动：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:padding="0dp" 
    > 
     <ListView 
     android:id="@+id/menu" 
     android:layout_width="match_parent" 
     android:layout_height="0dp" 
     android:layout_weight="1" 
     > 
     </ListView> 
     <com.traderscockpit.inflating.BottomBar 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_weight="0"   
      /> 
</LinearLayout>

这里我得到的堆栈跟踪：

我到现在还没有附加事件处理程序，不知道问题出在哪里。请帮忙。提前致谢。

你在xml包内有一个输入错误。它应该是com.traderscockpit.BottomBar，不com.traderscockpit.inflating.BottomBar

是，鹰眼的修复应该这样做 – bofredo

是的，非常感谢您的帮助。只要stackoverflow允许我这样做，将接受此答案... :) – Sourabh

BottomBar类是com.traderscockpit包，但你在XML文件中把它定义为com.traderscockpit.inflating
