【问题描述】：

这是我的代码，请检查并解决我的问题。在这个我通过图像路径获取图像，即我在selectimage1，selectimage2...继续，之后我在位图中拍摄了图像，然后解码并减小它的大小den也内存不足错误。

所以请帮我摆脱它。

谢谢

标签： android bitmap imageview

【解决方案1】：

您只需将这一行添加到您的清单文件中......它将为您的应用程序分配大内存......

android:largeHeap="true"

【解决方案2】：

试试看：

imageview1.setImageBitmap(null);
imageview2.setImageBitmap(null);
imageview3.setImageBitmap(null);
imageview4.setImageBitmap(null);
imageview1.setImageBitmap(thumbnail1);
imageview2.setImageBitmap(thumbnail2);
imageview3.setImageBitmap(bitmapsimplesize3);
imageview4.setImageBitmap(bitmapsimplesize4);

还有finish();以前无法使用的活动。

或者

AndroidManifest.xml

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

【讨论】：

我可以使用其他人可以使用的共享首选项，因为在共享首选项中它包含最后一张图片

【解决方案3】：

尝试缩小位图而不是压缩它。 Android 官方网站对此有非常详细的指南：http://developer.android.com/training/displaying-bitmaps/
