Handler 内部类导致的内存泄露修改方法

参考博客:作者：又宠又烦的Android女

官方方法

private Handler mHandler2 = new Handler(new Handler.Callback() { @Override public boolean handleMessage(Message msg) { return false; } });

使用弱引用

static class MyHandler extends Handler { WeakReference<OuterClass> outerClass; MyHandler(OuterClass activity) { outerClass = new WeakReference<OuterClass>(activity); } @Override public void handleMessage(android.os.Message msg) { OuterClass theClass = outerClass.get(); switch (msg.what) { case 0: { //使用theClass访问外部类成员和方法 break; } default: { Log.w(TAG, "未知的Handler Message:" + msg.what); } } } }
