直接上代码,使用两种办法
1,静态内部类
/** * 声明一个静态的Handler内部类,并持有外部类的弱引用 */private static class MyHandler extends Handler{ private final WeakReferencemActivty; private MyHandler(ServerActivity mActivty) { this.mActivty = new WeakReference (mActivty); } @Override public void handleMessage(Message msg) { super.handleMessage(msg); ServerActivity activity = mActivty.get(); if (activity != null){ //注意,这里的test,btn_closeServer都是成员变量 activity.test ="hello"; activity.btn_closeServer.setText(" 小样,你好吗"); } }}
2,
在activity 的ondestory()的时候,
调用mHandler.removeCallbacksAndMessages(null);
