HandlerThreadCreator

简单构造一个handlerThread，并得到其handler：

/**

public class HandlerThreadCreator {
    private HandlerThread mHandlerThread;
    private Handler mHandler;

    private void init(String name) {
        mHandlerThread = new HandlerThread(name);
        mHandlerThread.start();
        mHandler = new Handler(mHandlerThread.getLooper());
    }

    private void init2(String name, final Handler handler) {
        mHandlerThread = new HandlerThread(name);
        mHandlerThread.start();
        mHandler = new Handler(mHandlerThread.getLooper()) {

            @Override
            public void handleMessage(Message msg) {
                handler.handleMessage(msg);
            }

        };
    }

    public static Handler getHandler(String name) {
        HandlerThreadCreator h = new HandlerThreadCreator();
        h.init(name);
        return h.mHandler;
    }

    public static Handler getHandler(String name, Handler handler) {
        HandlerThreadCreator h = new HandlerThreadCreator();
        h.init2(name, handler);
        return h.mHandler;
    }

}

使用如下：

    private void invoke() {
      Handler aHandler =  HandlerThreadCreator.getHandler("a");
    }
