在app的活动图像视图中准确加载图像

Question

我正在尝试实现一个应用程序，其中在创建活动时在图像视图中加载大量图像 - 在滚动视图中正好有24个图像视图对齐。 当我用24 imageview作为启动器活动本身开始该活动时 - 它工作正常.. 但是，当我在欢迎屏幕之后将该活动用作第二个活动时，它会崩溃并说 - ＆gt;

这里是第15行，它在＆＃34; onCreate＆＃34; - ＆gt;

上显示错误-i.e

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); //line no 15 in my code(indicated in the logcat)
}

Answer 1

添加清单文件android：hardwareAccelerated =＆＃34; false＆＃34; ，android：largeHeap =＆＃34; true＆＃34;它适用于某些环境。

<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">

Answer 2

在你的清单中使用它：

<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">

Answer 3

使用Picasso和Glide等图片加载库。对于public static void loadToGlide(Context context, ImageView imageView, Object o) { Glide.with(context) .asBitmap() .apply(new RequestOptions() .centerCrop()) .transition(new BitmapTransitionOptions() .crossFade()) .load(o) .into(imageView); } ：

loadToGlide(context, yourImageView, R.drawable.yourImage);

致电：

OutOfMemoryError

他们将为您处理一切，尤其是{{1}}。

Answer 4

您可以使用recylerview而不是多个imagviews，并且可以使用volley imageloader或glide来加载seamlessely。
