谁能告诉我们如何从我们从另一个 Activity 传递的 Intent 中获取 请求代码 ？

最佳答案

如果你这样做

intent.putExtra("requestCode", requestCode);

您可以通过以下方式获取:

int requestCode = getIntent().getExtras().getInt("requestCode");

或者

如果你这样做 startActivityForResult 像这样:

startActivityForResult(intent, requestCode);

请求代码作为参数存在:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
