Android实现短视频画心效果

本文实例为大家分享了Android实现短视频画心效果的具体代码，供大家参考，具体内容如下

主布局

<?xml version='1.0' encoding='utf-8'?><RelativeLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:app='http://schemas.android.com/apk/res-auto' xmlns:tools='http://schemas.android.com/tools' android:layout_width='match_parent' android:layout_height='match_parent' android:orientation='vertical' tools:context='.MainActivity'><androidx.recyclerview.widget.RecyclerView android: android:layout_width='match_parent' android:layout_height='match_parent'></androidx.recyclerview.widget.RecyclerView> <SurfaceViewandroid: android:layout_width='match_parent'android:layout_height='match_parent'></SurfaceView></RelativeLayout>

适配器布局`

<?xml version='1.0' encoding='utf-8'?><LinearLayout xmlns:android='http://schemas.android.com/apk/res/android' android:orientation='vertical' android:layout_width='match_parent' android:layout_height='match_parent'> <com.shuyu.gsyvideoplayer.video.StandardGSYVideoPlayerandroid: android:layout_width='match_parent'android:layout_height='match_parent' /></LinearLayout>

Activity页面逻辑

适配器

package com.example.pagfany;import android.util.Log;import androidx.annotation.Nullable;import com.chad.library.adapter.base.BaseQuickAdapter;import com.chad.library.adapter.base.BaseViewHolder;import com.shuyu.gsyvideoplayer.GSYVideoManager;import com.shuyu.gsyvideoplayer.video.StandardGSYVideoPlayer;import java.util.List;public class BaseeAdap extends BaseQuickAdapter<StringBean, BaseViewHolder> { private StandardGSYVideoPlayer standardGSYVideoPlayer; public BaseeAdap(int layoutResId, @Nullable List<StringBean> data) {super(layoutResId, data); } private int aa=-1; @Override protected void convert(BaseViewHolder helper, StringBean item) { standardGSYVideoPlayer =helper.getView(R.id.detail);standardGSYVideoPlayer.setUp(item.getA(),true,'美女');standardGSYVideoPlayer.startPlayLogic(); } public void getreselat() {standardGSYVideoPlayer.release(); } public void getAllreselat() {GSYVideoManager.releaseAllVideos(); } public void gepalay(int position) {standardGSYVideoPlayer.setUp(shuzu.videoUrls[position],true,'美女');standardGSYVideoPlayer.startPlayLogic(); }}

自定义线性布局

package com.example.pagfany;import android.content.Context;import android.util.Log;import android.view.View;import androidx.annotation.NonNull;import androidx.recyclerview.widget.LinearLayoutManager;import androidx.recyclerview.widget.PagerSnapHelper;import androidx.recyclerview.widget.RecyclerView;public class BaseLinearLayoutManager extends LinearLayoutManager implements RecyclerView.OnChildAttachStateChangeListener { public BaseLinearLayoutManager(Context context) {super(context); } public BaseLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {super(context, orientation, reverseLayout); } private OnListener onListener;//接口 public void setOnListener(OnListener onListener) {this.onListener = onListener; } interface OnListener{void init();void reselat();void getplay(int position); } private PagerSnapHelper pagerSnapHelper;// @Override public void onAttachedToWindow(RecyclerView view) {super.onAttachedToWindow(view);pagerSnapHelper=new PagerSnapHelper();pagerSnapHelper.attachToRecyclerView(view);//RecyclerView的滑动view.addOnChildAttachStateChangeListener(this);//滑动状态监听 } private static final String TAG = 'BaseLinearLayoutManager'; @Override public void onScrollStateChanged(int state) {super.onScrollStateChanged(state);switch (state){ case RecyclerView.SCROLL_STATE_IDLE:View snapView = pagerSnapHelper.findSnapView(this);int position = getPosition(snapView);onListener.getplay(position);Log.i(TAG, 'onScrollStateChanged: '+position);break;} } @Override public void onChildViewAttachedToWindow(@NonNull View view) {Log.i(TAG, 'onChildViewAttachedToWindow: '+132456); } @Override public void onChildViewDetachedFromWindow(@NonNull View view) { if (onListener!=null){ onListener.reselat();//滑动下一个页面 让上个视频没有声音 清除缓存 } }}
