fragment+viewpager图片视频混合轮播（videoview+glide）
最近要做一个需求是图片和视频混合轮播，因为之前的话轮播都是用的banner,实现起来比较简单，就是new出来，把图片集合设置上就好了，之后就是一顿设置，所以想找一个可以能够实现的第三方，肯定有，但我还是没找到，大哭2333333，还是自己写吧，废话不多说，直接上干货
1.首先是页面
2activity里的代码
public class MainActivity extends AppCompatActivity {
private ViewPager viewPager;
private List fragments;
private MyHandler myHandler;
private FragmenetAdapter fragmenetAdapter;
private List list;
private String TAG="每次选中传的值";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initData();
initViews();
}
private void initData() {
myHandler=new MyHandler();
list = new ArrayList<>();
list.add(new bean("https://vdse.bdstatic.com//611ab9dc5d336b1de5eae1b560b158ed?authorization=bce-auth-v1/fb297a5cc0fb434c971b8fa103e8dd7b/2017-05-11T09:02:31Z/-1//add0017a6e913612db3ef360898b55f2f9580d67a847c8e9b9780b7d83e440cf.mp4","10","video"));
list.add(new bean("http://9890.vod.myqcloud.com/9890_4e292f9a3dd011e6b4078980237cc3d3.f20.mp4","5","video"));
list.add(new bean("http://img2.imgtn.bdimg.com/it/u=3817131034,1038857558&fm=27&gp=0.jpg","5","image"));
list.add(new bean("http://img1.imgtn.bdimg.com/it/u=4194723123,4160931506&fm=200&gp=0.jpg","5","image"));
list.add(new bean("http://img5.imgtn.bdimg.com/it/u=1812408136,1922560783&fm=27&gp=0.jpg","5","image"));
}
private void initViews() {
viewPager = findViewById(R.id.viewpager);
fragments = new ArrayList();
for (int i = 0; i < list.size(); i++) {
if(list.get(i).getType().equals("video")){
VideoFragment videoFragment = new VideoFragment();
fragments.add(videoFragment);
Bundle bundle = new Bundle();
bundle.putString("url",list.get(i).getUrl());
videoFragment.setArguments(bundle);
}else {
ImageFragment imageFragment = new ImageFragment();
fragments.add(imageFragment);
Bundle bundle = new Bundle();
bundle.putString("url",list.get(i).getUrl());
imageFragment.setArguments(bundle);
}
}
fragmenetAdapter = new FragmenetAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(fragmenetAdapter);
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
EventBus.getDefault().post(list.get(position).getUrl());
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
for (int i = 0; i < list.size(); i++) {
if(list.get(i).getUrl().endsWith("mp4")){
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Message msg=new Message();
msg.arg1=1;
MainActivity.this.myHandler.sendMessage(msg);
}else {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Message msg=new Message();
msg.arg1=1;
MainActivity.this.myHandler.sendMessage(msg);
}
}
}
}
}).start();
}
class MyHandler extends Handler {
public MyHandler(){}
public MyHandler(Looper L){
super(L);
}
@Override
public void handleMessage(Message msg) {
if(msg.arg1==1) {
int count = fragmenetAdapter.getCount();
if (count > 1) { // 多于1个，才循环
int index = viewPager.getCurrentItem();
index = (index + 1) % count;
viewPager.setCurrentItem(index, true);
fragmenetAdapter.notifyDataSetChanged();
}
}
}
}
@Override
protected void onDestroy() {
super.onDestroy();
}
} 3.适配器，FragmentPagerAdapter
public class FragmenetAdapter extends FragmentPagerAdapter {
private List list;
public FragmenetAdapter(@NonNull FragmentManager fm, List list) {
super(fm);
this.list = list;
}
@NonNull
@Override
public Fragment getItem(int position) {
return list.get(position);
}
@Override
public int getCount() {
return list.size();
} 4.最后是fragment，因为fragment里的布局分别就一个imageview 和videoview 布局就不放了
4.1.VideoFragment
public class VideoFragment extends BaseLazyLoadFragment {
private static final String TAG = "videofragment";
private VideoView videoFrag;
private String url;
private String againUrl;
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
EventBus.getDefault().register(this);
}
@Override
protected boolean setIsRealTimeRefresh() {
return false;
}
@Override
public void lazyLoadData() {
super.lazyLoadData();
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
protected void initData() {
Log.i(TAG, "视频url: "+againUrl);
if (mIsVisibleToUser){
videoFrag.setVideoURI(Uri.parse(url));
videoFrag.start();
}
}
@Override
public void onPause() {
super.onPause();
}
@Override
protected void initView() {
videoFrag = mRootView.findViewById(R.id.frag_vidoe);
Bundle arguments = this.getArguments();
if(arguments!=null){
url = arguments.getString("url");
}
}
@Override
protected int provideLayoutId() {
return R.layout.frag_video;
}
public void setVolume(float volume,Object object) {
try {
Class forName = Class.forName("android.widget.VideoView");
Field field = forName.getDeclaredField("mMediaPlayer");
field.setAccessible(true);
MediaPlayer mMediaPlayer = (MediaPlayer) field.get(object);
mMediaPlayer.setVolume(volume, volume);
} catch (Exception e) {
}
}
//接收发送来的String类型数据
@Subscribe(sticky = true)
public void setUurl(String Url) {
videoFrag.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
if (what == MediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START)
videoFrag.setBackgroundColor(Color.TRANSPARENT);
return true;
}
});
}
});
videoFrag.setVideoURI(Uri.parse(Url));
videoFrag.start();
}
@Override
public void onDestroy() {
super.onDestroy();
EventBus.getDefault().unregister(this);
}
}4.2,ImageFragment
public class ImageFragment extends BaseLazyLoadFragment {
private ImageView imageFrag;
private String url;
@Override
protected boolean setIsRealTimeRefresh() {
return false;
}
@Override
public void lazyLoadData() {
super.lazyLoadData();
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Glide.with(this).load(url).diskCacheStrategy(DiskCacheStrategy.RESOURCE).into(imageFrag);
}
@Override
protected void initData() {
}
@Override
protected void initView() {
imageFrag = mRootView.findViewById(R.id.frag_image);
Bundle arguments = this.getArguments();
if(arguments!=null){
url = arguments.getString("url");
}
}
@Override
protected int provideLayoutId() {
return R.layout.frag_image;
}
这样就ok了，放个美旅镇一镇，23333333333333333333333333333333
