Question

我在我的项目中使用Kotlin和Java。我正在为Kotlin的结果打开一个Java活动，但是用Kotlin编写的onActivityResult函数永远不会被调用。

代码（Kotlin）：

 override fun viewAllNotes() {
        val intent : Intent = Intent(this, ViewAllNotesActivity::class.java)
        intent.putExtra(AppConstants.VIEW_ALL_FLOW, AppConstants.VIEW_ALL_NOTES_FLOW)
        startActivityForResult(intent, VIEW_ALL_REQUEST_CODE)
 }


override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == Activity.RESULT_OK){
        if (requestCode == VIEW_ALL_REQUEST_CODE){
            if (data!!.getParcelableArrayListExtra<ListNote>(AppConstants.NOTES_LIST)!=null){
                mViewModel.mNotesReminders.listNote = data.getParcelableArrayListExtra(AppConstants.NOTES_LIST)
            }
        }
    }
}

代码（Java）：

 @Override
 public void onBackPressed() {
        Intent result = new Intent();
        result.putParcelableArrayListExtra(AppConstants.NOTES_LIST, mNotesList);
        setResult(Activity.RESULT_OK, result);
        this.finish();
 }

logcat的

有谁能告诉我上面的代码有什么问题？

从kotlin调用java活动获取结果时，不会调用onActivityResult
