Question

我想将imageview中的图像旋转为3d图像。因此，我使用列表级别imageview在drawable中添加了50张图像。当我在images.xml中添加50张图像时，应用程序崩溃了，但是如果我添加12张图像，则它会完美地工作。我不知道为什么会发生此错误。我还没有找到任何解决方案。帮助我摆脱这个问题。

images.xml

<level-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:maxLevel="0" android:drawable="@drawable/one"/>
    <item android:maxLevel="1" android:drawable="@drawable/two"/>
    .
    .
    .
    <item android:maxLevel="50" android:drawable="@drawable/fifty"/>
</level-list>

activity.xml

<ImageView
    android:layout_width="match_parent"
    android:layout_height="170dp"
    android:layout_centerVertical="true"
    android:layout_above="@+id/mid"
    android:paddingTop="40dp"
    android:id="@+id/car_icon"
    app:srcCompat="@drawable/images"
    />

Activity.java

        imageView =  findViewById(R.id.car_icon);
        imageView.setImageLevel(x);

        "x varies depends on onTouchEvent from (0 to 50)"

您一次加载太多高分辨率图像。 Android Training docs建议您先缩放图像，然后再将其显示在UI上。根据个人喜好，我依靠Glide或Picasso之类的库来有效显示//Creating Test Data val df = Seq("[2019-01-10T23:59:59.998-06:00] [xx_yyy_zz_sss_ra10] [ERROR] [OSB-473003] [oracle.osb.statistics.statistics] [tid: [ACTIVE].ExecuteThread: '28' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: <anonymous>] [ecid: 92b39a8b-8234-4d19-9ac7-4908dc79c5ed-0000bd0b,0] [partition-name: DOMAIN] [tenant-name: GLOBAL] Aggregation Server Not Available.
