在app的活动的imageview中准确加载图像 _imageView

【在app的活动的imageview中准确加载图像】于今腐草无萤火，终古垂杨有暮鸦。这篇文章主要讲述在app的活动的imageview中准确加载图像相关的知识，希望能为你提供帮助。
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启动该活动时 - 它工作正常..但是，当我在欢迎屏幕后使用该活动作为第二个活动时它崩溃并说 - >

我怎么能克服这个错误？

这里是第15行，它在“onCreate” - > 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) }

答案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">

另一答案添加清单文件android：hardwareAccelerated =“false”，android：largeHeap =“true”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">

另一答案使用像Glide和Picasso这样的图像加载库。对于Glide：

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); }
