为什么我的Handler类中没有sendMessge方法，感觉写这个Handler中方法完全不一样的。

Question

public void run() {
    try {
        URL url = new URL(mUrlName);
        HttpURLConnection fileConection = (HttpURLConnection) url.openConnection();
        fileConection.setRequestMethod("GET");
        fileConection.setReadTimeout(8000);
        fileConection.setConnectTimeout(8000);
        InputStream is = fileConection.getInputStream();
        int TotalLen = fileConection.getContentLength();
        Bitmap bitmap = BitmapFactory.decodeStream(is);
        Message message = Message.obtain();
        message.what = 10008;
        message.obj = bitmap;
        //mHandler.sendMessage(message);
        mHandler.sendMessage(message);//此处在编辑器里显红，说明没有此方法
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException E){
        E.printStackTrace();
    }
}

看一下你的handler 是哪一个包下的handler需要是  下面这个包下的import android.os.Handler;你有可能导包错了，导成了java.util.logging.Handler
