Question

我正在使用viewpager来显示3个屏幕，例如入门屏幕。在所有手机上都可以正常工作，但在Moto X4中无法正常工作。这些是Moto X4的屏幕截图：

这是xml代码：

Java代码：

public class LoginSliderAdapter extends PagerAdapter {

    public int slider_videos[] = {
            R.raw.v1,
            R.raw.v2,
            R.raw.v3
    };
    @BindView(R.id.iv_slider_image)
    VideoView sliderImage;
    @BindView(R.id.tv_slider_title)
    TextView sliderTitle;
    @BindView(R.id.tv_slider_description)
    TextView sliderDescription;
    Context context;
    LayoutInflater layoutInflater;

    public LoginSliderAdapter(Context context) {
        this.context = context;
    }

    @Override
    public int getCount() {
        return 3;
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object o) {
        return view == o;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
        View view = layoutInflater.inflate(R.layout.login_slider, container, false);
        ButterKnife.bind(this, view);
        setVideoToVideoPlayer(position);
        sliderTitle.setText(context.getResources().getStringArray(R.array.login_tiles)[position]);
        sliderDescription.setText(context.getResources().getStringArray(R.array.login_desc)[position]);
        container.addView(view);
        return view;
    }

    private void setVideoToVideoPlayer(int position) {
        Uri uri = Uri.parse("android.resource://com.sharesmile.share/"
                + slider_videos[position]);
        sliderImage.setBackgroundColor(Color.TRANSPARENT);
        sliderImage.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                mp.setLooping(true);
            }
        });
        sliderImage.setVideoURI(uri);
        sliderImage.requestFocus();
        sliderImage.setZOrderOnTop(true);
        sliderImage.start();
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((LinearLayout) object);
    }
}

那么这个问题是什么，无法弄清楚，永远不会这样。
