android handler 兑现三步曲

android handler 实现三步曲

一. 要实现接口：

public boolean handleMessage(Message message) {// TODO Auto-generated method stubtry {switch (message.what) {case UPLOAD_SUCCESS:Toast.makeText(VrowsePicActivity.this,(String) message.obj.toString(), Toast.LENGTH_SHORT).show();case UPLOAD_ERROR:Toast.makeText(VrowsePicActivity.this,(String) message.obj.toString(), Toast.LENGTH_SHORT).show();default:break;}} catch (Exception e) {Log.i("db", "VrowsePicActivity=handler error");e.printStackTrace();}return false;}

?
