请看看下面的code：

Please have a look at the code below:

public class MyGridFragment extends Fragment{

     Handler myhandler = new Handler() {
    @Override
    public void handleMessage(Message message) {
        switch (message.what) {
        case 2: {

            ArrayList<HashMap<String,String>> theurls = (ArrayList<HashMap<String,String>>) message.obj;
            urls.addAll(theurls);
            theimageAdapter.notifyDataSetChanged();
            dismissBusyDialog();
            break;
        }}}};
         }

当我使用的处理程序是这样，我得到一个警告处理程序应该是静态的，否则很容易出现内存泄漏。谁能告诉我什么是做到这一点的最好方法是什么？

When I use handler like this I get a warning "handler should be static, else it is prone to memory leaks." Can someone tell me what is the best way to do this?

推荐答案

我最近更新了自己的code类似的东西。我只是做匿名处理程序类受保护的内部类和皮棉警告走了。看看像下面code会为你工作：

I recently updated something similar in my own code. I just made the anonymous Handler class a protected inner class and the Lint warning went away. See if something like the below code will work for you:

public class MyGridFragment extends Fragment{

    static class MyInnerHandler extends Handler{
        WeakReference<MyGridFragment> mFrag;

        MyInnerHandler(MyGridFragment aFragment) {
            mFrag = new WeakReference<MyGridFragment>(aFragment);
        }

        @Override
        public void handleMessage(Message message) {
            MyGridFragment theFrag = mFrag.get();
            switch (message.what) {
            case 2:
                ArrayList<HashMap<String,String>> theurls = (ArrayList<HashMap<String,String>>) message.obj;
                theFrag.urls.addAll(theurls);
                theFrag.theimageAdapter.notifyDataSetChanged();
                theFrag.dismissBusyDialog();
                break;
            }//end switch
        }
    }
    MyInnerHandler myHandler = new MyInnerHandler(this);
}

您可能需要更改的地方，我把theFrag。我只能猜测，什么这些引用。

You may have to change where I put "theFrag." as I could only guess as to what those referenced.
