	}

	public void hello(View view){

		String content = et_content.getText().toString();
		
		/**
		 * 以下是发短信的核心代码
		 */
		SmsManager smsManager = SmsManager.getDefault();
		List<String> list = smsManager.divideMessage(content);//分割短信内容.用于处理一条短信太长的情况...
		for(String str : list){
			smsManager.sendTextMessage(num, null, str, null, null);
		}
		
		Toast.makeText(this, "hello sms", 1).show();
