Я создаю что-то вроде поста в Facebook. Где пользователь может загружать изображения и видео, а также просматривать их. Поэтому я создаю arrayList из файлов, и если пользователь щелкает любое изображение или видео, он переносит их в новое действие, чтобы отобразить все файлы в окне просмотра, передавая arrayList и индекс выбранного файла в качестве параметров, чтобы я мог использовать arrayList для установки моего адаптера и положения моего виджета на индекс файла, по которому щелкнули.
Итак, вот мое действие, которое отображает файлы
Bundle fileParams = getIntent().getExtras();
filePosition = fileParams.getInt("index");
allFiles = fileParams.getStringArrayList("arrayList");
photoOpenerAdapter = new PhotoOpenerAdapter(allFiles, cntxt);
viewPager = (ViewPager) findViewById(R.id.viewPager);
viewPager.setAdapter(photoOpenerAdapter);
viewPager.setCurrentItem(filePosition);
viewPager.setOffscreenPageLimit(allFiles.size());
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
viewPager.post(new Runnable() {
@Override
public void run() {
//loadedInitial is a boolean value to make this thread run only once
if(!loadedInitial) {
loadedInitial = true;
String filePath = allFiles.get(position);
String fileType = functions.getmInstance(cntxt).checkFileType(filePath);
if(fileType == "video")
startVideoPlayer(position);
}
}
});
}
@Override
public void onPageSelected(int position) {
pauseVideoPlayer();
String filePath = allFiles.get(position);
String fileType = functions.getmInstance(cntxt).checkFileType(filePath);
if(fileType == "video") {
startVideoPlayer(position);
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
private void pauseVideoPlayer() {
if(!(videoView == null)){
videoView.pause();
}
}
public static void startVideoPlayer(int position) {
View videoLayout = viewPager.getChildAt(position);
videoView = (VideoView) videoLayout.findViewById(R.id.videoPlayer);
if(!(videoView == null)) {
videoView.requestFocus();
videoView.start();
}
}
}
А вот instantiateItem поток моего PhotoOpenerAdapter.java класса
@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, final int position) {
layoutInflater = LayoutInflater.from(context);
String imageUrl = postFilesLists.get(position);
String fileType = functions.getmInstance(context).checkFileType(imageUrl.toLowerCase());
if(fileType == "video") {
view = layoutInflater.inflate(R.layout.video_player, container, false);
VideoView videoView = (VideoView) view.findViewById(R.id.videoPlayer);
Uri uri = Uri.parse(imageUrl);
videoView.setVideoURI(uri);
} else{
view = layoutInflater.inflate(R.layout.photo_opener, container, false);
ImageView imageView = (ImageView) view.findViewById(R.id.image);
imageLoader.displayImage(imageUrl, imageView);
}
container.addView(view);
return view;
}
Этот код работает нормально, но когда filePosition - это видеофайл, и я пытаюсь использовать поток onPageScrolled для загрузки URL-адреса видео, я получаю ошибка java.io.FileNotFoundException: No content provider: http://, которая исходит из строки Uri uri = Uri.parse(imageUrl);, но если filePosition является файлом изображения, и я прокручиваю до видеофайла, onPageSelected успешно воспроизводит видео.
Пожалуйста, я не то, что я делаю не так
