会有人请解释RESULT_FIRST_USER [英] Will someone please explain RESULT_FIRST_USER
问题描述
我不明白其中的含义,价值,或RESULT_FIRST_USER的重要性,除此之外我自己的结果codeS必须大于 1
。会有人请解释一下吗? RESULT_OK和RESULT_CANCELED鲜明了意义讲英语的人。但在Android的世界是什么RESULT_FIRST_USER?所有单证说,大约是
启动用户自定义的活动的结果。
当你完成一个活动,你可以叫的setResult(RESULT_ code)
发送回数据到另一个活动。如果你不调用这个方法,默认值将是 RESULT_FIRST_USER
返回数据的例子:
意向意图=新的意图();
intent.putExtra(数据,数据);
的setResult(YOUR_RESULT_ code,意图);
完();
I don't understand the meaning, value, or importance of RESULT_FIRST_USER, other than that my own result codes must be greater than 1
. Will someone please explain it? RESULT_OK and RESULT_CANCELED make perfect sense to an english speaker. But what in the world of android is RESULT_FIRST_USER? All the documentations says about it is
Start of user-defined activity results.
When you finish an activity, you can call setResult(RESULT_CODE)
to send back data to another activity. If you don't call this method, the default value will be RESULT_FIRST_USER
Example of returning data:
Intent intent= new Intent();
intent.putExtra("data",data);
setResult(YOUR_RESULT_CODE,intent);
finish();
