Android : 以动态时间间隔显示照片和视频

Question

我想以动态时间间隔显示照片和视频的数量。我的条件是

1) 以动态间隔显示照片 2）当有视频时，播放视频并停止任务， 3) 播放视频恢复线程或我们使用过的任何内容后。

我尝试使用线程，但视频出现问题，并且线程行为异常。有没有更好的解决方案或建议，

以下是我在 MainActivity.class

中的代码

timer = new Thread() {

        public void run() {
            try {
                for (int z = 0; z < userStories.size(); z++) {

                    Log.e("File Name--->", userStories.get(z).getFileName());
                    Log.e("File TYPEEEE--->", userStories.get(z).getType());
                    if (userStories.get(z).getType().equalsIgnoreCase("photo")) {
                        Log.e("SLEEEEEPppp-->", "SO GAYA THREAD");
                        sleep(Long.parseLong(userStories.get(z).getDisplayTime()) * 1000);
                        final int finalZ = z;
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                image.setVisibility(View.VISIBLE);
                                video_view.setVisibility(View.GONE);
                                Glide.with(getApplicationContext())
                                        .load(userStories.get(finalZ).getFileName())
                                        .into(image);
                            }
                        });
                    } else if (userStories.get(z).getType().equalsIgnoreCase("video")) {

您可以改用处理程序，尝试下面的代码。首先你必须调用 CallNext() 方法。

private void bindHandler() {
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            callNext();
            Log.e("In HANDLER------>", "HANDLER");
        }
    }, DISPLAY_LENGTH * 1000);
}



  private void callNext() {
    if (counter < statusModel.getStories().get(position).getUserStories().size()) {
        if (statusModel.getStories().get(position).getUserStories().get(counter).getType().equalsIgnoreCase("photo")) {
            Log.e("PHOTOOOO--->", "PHOTOOOOO");

            String photo = statusModel.getStories().get(position).getUserStories().get(counter).getFileName();
            image.setVisibility(View.VISIBLE);
            video_view.setVisibility(View.GONE);
            Glide.with(getApplicationContext())
                    .load(photo)
                    .into(image);
            counter++;
            DISPLAY_LENGTH = Long.parseLong(statusModel.getStories().get(position).getUserStories().get(counter).getDisplayTime());
            Log.e("DIAPLAY TIME--->", String.valueOf(DISPLAY_LENGTH));
            bindHandler();
        } else {
            if (statusModel.getStories().get(position).getUserStories().get(counter).getType().equalsIgnoreCase("video")) {
                Log.e("VIDEOOOO--->", "VIDEOOOOO");
                image.setVisibility(View.GONE);
                video_view.setVisibility(View.VISIBLE);
                String VideoURL = statusModel.getStories().get(position).getUserStories().get(counter).getFileName();
                uri = Uri.parse(VideoURL);
                if (!TextUtils.isEmpty(VideoURL)) {
                    video_view.setVideoURI(uri);
                    video_view.requestFocus();
                    video_view.start();
                    video_view.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                        @Override
                        public void onPrepared(MediaPlayer mediaPlayer) {

                        }
                    });

                    video_view.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                        @Override
                        public void onCompletion(MediaPlayer mediaPlayer) {
                            Log.e("VIDEooooooo--->", "Completeeeee");

   Log.e("Thread Notifyyyy--->", "Hooo Gayaaaaaa");
                            counter++;
                            callNext();
                        }
                    });
                }
            }
        }
    }
