java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()解决办法

android Toast提示异常：java.lang.RuntimeException: Can't create handler inside thread that has not called

原因是在子线程弹Toast了， 切记，Toast只能在UI线程弹出

解决办法：

new Thread(new Runnable() {  

            @Override
            public void run() {
                // TODO Auto-generated method stub  

                try {
                    Thread.sleep(1000);
                    handler.sendEmptyMessage(0);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }  

            }
        }).start();

　　

private Handler handler = new Handler() {  

        @Override
        public void handleMessage(Message msg) {

　　　　　　Toast.makeText(CommodityDetails.this, "修改失败！", Toast.LENGTH_SHORT).show();

} };

　　

完美解决！！！
