android - appwidget listview 重复值

Question

我知道我们在标准 Android 应用程序中使用“convertView”变量检查来处理“Recycler”。有没有什么方法可以在小部件开发中处理它，因为 RemoteAdaptersFactory 有一个方法 getViewAt 并且这个方法没有像 convertView 这样的参数。只是一个整数“位置”。注意:我正在使用 layout:match_parent

我的代码:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/xxxxx"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/yyyy"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="fitXY" />

<TextView
    android:id="@+id/zzzzzzz"
    android:layout_width="wrap_content"
    android:layout_height="40dp"
    android:text="Aylik aktiviteler"
    android:textColor="#000000" />

<RelativeLayout
    android:id="@+id/bbbbb"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/aaaaaa" >

    <ListView
        android:id="@+id/cccccc"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="20dp"
        android:scrollingCache="false" >

    </ListView>

    <TextView
        android:id="@+id/dddddd"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        android:visibility="gone" />

</RelativeLayout>

<Button
    android:id="@+id/aaaaa"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:text="+" />

</RelativeLayout>

经过多次尝试和谷歌一个月的搜索，今天我找到了解决方案。在 ListView 中使用 ImageView 时，您应该在每次调用 getViewAt 时启动每个 ImageView 。我在每种情况下都调整了 imageview 选择，但忘记了初始化。在 getViewAt 中，我分配了一个没有内容的透明图像。问题解决了。
