Android 图片三级缓存之内存缓存（告别软引用(SoftRefrerence)和弱引用(WeakReference)）在过去，我们经常会使用一种非常流行的内存缓存技术的实现，即软引用或弱引用 (SoftReference or WeakReference)。但是现在已经不再推荐使用这种方式了，因为从 Android 2.3 (API Level 9)开始，垃圾回收器会更倾向于回收持有软引用或弱引用的对象，这让软...

Android 弱引用和软引用软引用和弱引用 1. SoftReference<T>：软引用-->当虚拟机内存不足时，将会回收它指向的对象；需要获取对象时，可以调用get方法。 2. Weak...

Android开发优化之——使用软引用和弱引用 Java从JDK1.2版本开始，就把对象的引用分为四种级别，从而使程序能更加灵活的控制对象的生命周期。这四种级别由高到低依次为：强引用、软引用、弱引用和虚引用。这里重点介绍一下软引用和弱引用。如果一个对象只具有软引用，那么如果内存空间足够，垃圾回收器就不会回收它；如果内存空间不足了，就会回收这些...
