Android 广告机图片视频轮播
2024-05-31 13:34:16
最近因为要做一个广告机上图片视频轮播，所以又是百度，github上一堆找，结果发现并没有特别合适的，不是播放视频首帧黑屏，就是切换界面后，没法继续播放，或者动态更新数据后，没法继续轮播等等问题，所以最后结合别人的方案自己修改了一下，具体参考android 实现图片和视频混合轮播_android 图片视频轮播_a1466850214的博客-CSDN博客
修改完成后，1.可以实现无黑屏
2.切换界面后，回到播放界面继续上次播放位置播放，
3.不支持点击和手动切换
4.动态更新数据后继续播放
下面是具体代码:
1.播放实体类
public class Advance {public String path;//路径 我使用的是本地绝对路径public String type;//类型 1、视频 2、图片public Advance(String path, String type) {this.path = path;this.type = type;}
}2.图片类
package com.anssy.smartbox.selfview.videoplay;import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;
import android.widget.RelativeLayout;import com.anssy.smartbox.utils.glide.GlideApp;public class AdvanceImageView extends RelativeLayout {private ImageView imageView;public AdvanceImageView(Context context) {super(context);initView();}public AdvanceImageView(Context context, AttributeSet attrs) {super(context, attrs);initView();}public AdvanceImageView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);initView();}private void initView() {imageView = new ImageView(getContext());imageView.setScaleType(ImageView.ScaleType.FIT_XY);addView(imageView, new RelativeLayout.LayoutParams(-1, -1));}public void setImage(String path) {GlideApp.with(getContext()).load(path).into(imageView);}}3.视频播放类，这里面的播放视频控件，没有采用和其他博主用的系统VideoView,这里引用一个第三方，大家可以在gradle里面导入，至于为什么引入第三方，1.可以实现缓存2.视频pause后，切回后，可以无缝播放，Application中加入初始化，如果有视频播放不了，请切换内核为AndroidMediaFactory.create()或切换为ExoPlayer，具体参考GitHub - Doikki/DKVideoPlayer: Android Video Player. 安卓视频播放器，封装MediaPlayer、ExoPlayer、IjkPlayer。模仿抖音并实现预加载，列表播放，悬浮播放，广告播放，弹幕，视频水印，视频滤镜

}5.播放控件，其实是ViewPager切换
package com.anssy.smartbox.selfview.videoplay;import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.RelativeLayout;import androidx.viewpager.widget.ViewPager;import java.util.ArrayList;
import java.util.List;public class AdvanceView extends RelativeLayout {private ViewPager viewPager;private List<View> views = new ArrayList<>();public AdvancePagerAdapter adapter;public AdvanceView(Context context) {super(context);initView();}public AdvanceView(Context context, AttributeSet attrs) {super(context, attrs);initView();}public AdvanceView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);initView();}@SuppressLint("ClickableViewAccessibility")private void initView() {viewPager = new ViewPager(getContext());viewPager.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {return true;}});adapter = new AdvancePagerAdapter(getContext(),viewPager);viewPager.setAdapter(adapter);addView(viewPager, new RelativeLayout.LayoutParams(-1, -1));}public void setData(List<Advance> advances) {adapter.setData(advances);}public void setDestroy(){adapter.setDestroy();}public void setPause(){adapter.setPause();}public void setResume(){adapter.setResume();}
}6.ViewPager的适配器，里面原作者的代码我并未删除，大家也可以对比下，或者区别调用下，看下效果，我将原作者的thread定时器，改为了handler的方法，这样可操作性要强一点，避免动态切换数据后，轮播卡死的情况。这里我用的是自己定义的handler,大家替换为系统的handler即可
