android中子线程操作UI的问题

<span style="background-color: rgb(255, 255, 255); font-family: Arial, Helvetica, sans-serif;">实现方法1：</span>

runOnUiThread(new Runnable() {
								@Override
								public void run() {
									
								}
							});

new Thread(new Runnable() {

				@Override
				public void run() {
					Looper.prepare();  //looper一定要放在run方法内
					register(sName, sPwd);
					Looper.loop();//开启looper循环

<span style="white-space:pre">					Looper.myLooper().quit();</span>
				}
			}).start();
