请查看以下代码

</LinearLayout>

此处， common_status_bar.xml 是一种常见布局。我已通过game_activity.xml将此布局添加到<include layout="@layout/common_status_bar"/>。

它显示一切正常，没有问题。但情况是我无法使其中的任何元素起作用。我已将OnClickListener附加到goToLanguageSelection的第一个元素，但它没有响应Click。我通过将click事件添加到所有其他按钮，图像（一次一个）来测试这个，我得到了相同的结果。它没有响应用户点击，或其他什么。

为什么单独布局中的此按钮和图像不响应用户事件？

不应再次创建commonView。

如果你想保留common_status_bar.xml的引用，你可以用id命名，如下面的代码：

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="10dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="10dp" >

        <include
            android:id="@+id/common_status_bar"
            layout="@layout/common_status_bar" />

    </RelativeLayout>

然后，更改此代码：

       commonView = layoutInflater.inflate(R.layout.common_status_bar, null);

为：

       commonView = findViewById(R.id.common_status_bar);

另一种布局中的项目不响应用户事件
