Java 空视图不显示任何内容

基本上我有一个ListView（lv），它显示一组项目，如果lv为空，则显示EmptyView，但不显示任何代码：

ListView l = (ListView) view.findViewById(R.id.ArrayList);
    l.setAdapter(adapter);
    srl = (SwipeRefreshLayout) view.findViewById(R.id.refreshView);
    srl.setOnRefreshListener(srfListener());
    View Empty = inflater.inflate(R.layout.empty,null);
    l.setEmptyView(Empty);

XML文件：

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:text="Nothing Available "
    android:textSize="30sp"
    android:textColor="@color/colorPrimary"
    android:layout_height="match_parent"
    >
</TextView>

有没有办法解决这个问题？？顺便说一下，这不是列表活动。

根据您的代码，您正在创建视图并将其添加为列表中的emptyView

View Empty = inflater.inflate(R.layout.empty,null);
l.setEmptyView(Empty);

但您可以看到下面的实际代码，它只是使可见和消失，而不是添加到您的布局中

private void updateEmptyStatus(boolean empty) {
        if (isInFilterMode()) {
            empty = false;
        }

        if (empty) {
            if (mEmptyView != null) {
                mEmptyView.setVisibility(View.VISIBLE);
                setVisibility(View.GONE);
            } else {
                // If the caller just removed our empty view, make sure the list view is visible
                setVisibility(View.VISIBLE);
            }

            // We are now GONE, so pending layouts will not be dispatched.
            // Force one here to make sure that the state of the list matches
            // the state of the adapter.
            if (mDataChanged) {           
                this.onLayout(false, mLeft, mTop, mRight, mBottom); 
            }
        } else {
            if (mEmptyView != null) mEmptyView.setVisibility(View.GONE);
            setVisibility(View.VISIBLE);
        }
    }

因此，将其添加到布局中，然后将该视图提供给

setEmptyView

你可以这样加上

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:swipe="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="top"
    android:background="@color/dark_bg_color"
    android:gravity="top"
    android:orientation="vertical" >
    <ListView
        android:id="@+id/recentcall_listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:cacheColorHint="@color/transparent"
        android:divider="#cecece"
        android:dividerHeight="1dp"
        android:listSelector="@color/transparent"
         />

    <ViewStub
        android:id="@android:id/empty"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:layout_margin="20dp"
        android:layout="@layout/[your empty layout]" />

</LinearLayout>

ViewStub emptyViewStub = (ViewStub) view.findViewById(android.R.id.empty);
l.setEmptyView(emptyViewStub);

您能为您的listview发布XML吗？
