java.lang.RuntimeException：无法启动活动

-1

我想使用ViewFlipper，但我在setContentView(R.layout.activity_main);行发现此错误;java.lang.RuntimeException：无法启动活动

当我回到轨道时，当我仅添加第二个LinearLayout时，出现此错误。我看了使用ViewFlipper的例子，我没有看到问题。

这里是XML文件：

    //viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper); 
} 

@Override

    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override

    } 

    return super.onOptionsItemSelected(item); 
} 

public void viewTimeSheet(View view){ 
    viewFlipper.showNext(); 
} 
}

以下是错误：

这里：

<linearLayout 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    ... 

</linearLayout>

应该是：

<LinearLayout 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    ... 

</LinearLayout>

（上盖）

注意，XML是区分大小写的。
