out-of-memory - 使用 RecyclerView 时出现 android OutOfMemoryError

Question

我正在使用 recyclerview 创建一个应用程序。当我尝试在移动设备上滚动它时，出现以下错误。

下面是 recyclerview 的布局:

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/relative1">
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="480dp"
          android:scaleType="fitXY"
            android:id="@+id/imageView1"/>

            <TextView
                android:layout_width="match_parent"
                android:layout_height="60dp"
                android:id="@+id/textView1"

                android:layout_centerHorizontal="true"
                android:layout_below="@+id/imageView1"
                android:textSize="35sp"
                android:textColor="#263238"/>
            <TextView
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:id="@+id/textView2"

                android:layout_centerHorizontal="true"
                android:layout_below="@+id/textView1"
                android:textSize="20sp"
                android:textColor="#263238"/>
    </RelativeLayout>

RecyclerView 类:

Answer 1

尝试使用 Picasso 从资源可绘制文件夹加载图像

这可以通过使用以下代码来完成:

Picasso.with(context).load(R.drawable.drawableName).into(imageView);
