我知道我们在标准Android应用程序中通过“ convertView”变量检查来处理“ Recycler”。有什么方法可以在小部件开发中处理它，因为RemoteAdaptersFactory具有方法getViewAt且该方法没有像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>

最佳答案
经过数次试用和一个月的Google搜索后，今天我找到了解决方案。在列表视图中使用imageviews时，应在每次getViewAt调用时启动每个imageview。我在每种情况下都对imageview进行了选择，但是却忘记了初始化。在getViewAt，我分配了一个没有内容的透明图像。问题解决了。
