Question

    fileHippoWrapper = (LinearLayout) findViewById(R.id.filehippo_wrapper2);
    fileHippoWrapper.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(FinalChatActivity.this, "FileHippo", Toast.LENGTH_SHORT).show();
            AlAttachmentOptions.processLocationAction(getActivity(), null);

        }
    });

我无法从其说的另一活动processLocationAction导入功能AlAttachmentOptions

无法解析方法getActivity（）

Answer 1

Android活动中没有let story = 'Last weekend, I took literally the most beautiful bike ride of my life. The route is called "The 9W to Nyack" and it actually stretches all the way from Riverside Park in Manhattan to South Nyack, New Jersey. It\'s really an adventure from beginning to end! It is a 48 mile loop and it basically took me an entire day. I stopped at Riverbank State Park to take some extremely artsy photos. It was a short stop, though, because I had a really long way left to go. After a quick photo op at the very popular Little Red Lighthouse, I began my trek across the George Washington Bridge into New Jersey. The GW is actually very long - 4,760 feet! I was already very tired by the time I got to the other side. An hour later, I reached Greenbrook Nature Sanctuary, an extremely beautiful park along the coast of the Hudson. Something that was very surprising to me was that near the end of the route you actually cross back into New York! At this point, you are very close to the end.'; let storyWords = story.split(' ') console.log(storyWords) console.log(storyWords.length) let overusedWords = ['really', 'very', 'basically']; let unnecessaryWords = ['extremely', 'literally', 'actually' ]; let betterWords = storyWords.filter( storyWords => !unnecessaryWords.includes(storyWords.toLowerCase())); console.log(betterWords)方法。这只是表明您需要在此处获取活动参考。

因此，使用getActivity()或getActivity()代替this。它将起作用。

因此您的代码将：

FinalChatActivity.this

Answer 2

使用 AlAttachmentOptions.processLocationAction(FinalChatActivity.this, null);

Answer 3

@TruongHieu的答案的附加说明getActivity()中不存在onClick(View view)，因此您不能仅从那里调用getActivity（）。

要获取当前Activity的活动，您需要执行与Toast语句相同的操作。

Toast.makeText(FinalChatActivity.this, "FileHippo", Toast.LENGTH_SHORT).show();
AlAttachmentOptions.processLocationAction(FinalChatActivity.this, null);

希望有帮助。
