android handler ,message消息发送方式

1.Message msg =  Message.obtain(mainHandler)

  msg.obj=obj;//添加你需要附加上去的内容

  msg.what = what;//what消息处理的类型

  msg.sendToTarget();

获取消息:String msg2= (String)msg.obj;Log.i(TAG, "msg1::"+msg2);

2.Message msg = mHandler.obtainMessage(MSG_NOTICE_SUCCESS);

Bundle bundle = new Bundle();
bundle.putInt("id",id);
bundle.putLong("startTime",startTime);
bundle.putLong("endTime",endTime);
msg.setData(bundle);

msg.sendToTarget();

获取消息:Bundle data = msg.getData();

int id = data.getInt("id");
long effectiveTime = data.getLong("endtime");

3.当不需要传递数据时:

Handler.sendEmptyMessage(MSG_LOAD_ERROR);

4.发送延时消息:

Handler.sendEmptyMessageDelayed(MSG_DELAY_LOAD_REFRESH, 2000);
