如何在带有片段的布局中的列表视图下方的页脚中添加按钮。我有如下代码:

在片段 java.

ListView listview;
Button button;


public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.category, container, false);
        View footerView = inflater.inflate(R.layout.footer_category, null);
        listview = (ListView) view.findViewById(R.id.categoryNewsItemGrid);
        listview.addFooterView(footerView);

    loadmore = (Button) footerView.findViewById(R.id.loadMore);
    loadmore.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Log.d("Mylog","Button can click");
        }
    });

        return view;
}

/res/layout/category.xml

<?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" >

    <ListView
        android:id="@+id/categoryNewsItemGrid"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:divider="#C5C5C5"
        android:dividerHeight="2px" />

</LinearLayout>

/res/layout/footer_category.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/footerCategory"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <Button
        android:id="@+id/loadMore"
        android:layout_width="fill_parent"
        android:text="Load More" />

</LinearLayout>

我得到错误(强制关闭),如果我在 logcat 中看到,我在第 74 行收到消息错误 Android 运行时,第 74 行是:

View footerView = inflater.inflate(R.layout.footer_category, null);

我的问题,我想在列表视图下方的页脚中添加按钮。就像这个截图一样。谢谢。

您错过layout_height/res/layout/footer_category.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/footerCategory"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <Button
        android:id="@+id/loadMore"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Load More" />

</LinearLayout>
