【问题描述】：
我正在使用带有片段的 View Pager 来显示图像和视频，我能够正确显示图像和视频但我有问题，当我滑动视频时，视频正在播放，但我滑动下一个或上一个然后视频是仍在下一个或上一个屏幕上播放，但是当我将两张幻灯片移动到下一个或上一个时，视频将停止，但为什么不在下一个或上一个幻灯片上播放。
我搜索了更多，但没有得到任何解决方案，任何帮助都会很明显。 提前致谢。
这是我的代码：
这是片段类
public class ContentFragment extends Fragment {
private final String imageResourceId;
private String type;
public ContentFragment(String imageResourceId,String type) {
System.out.println("Path In cons="+imageResourceId+"and type is="+type);
this.imageResourceId = imageResourceId;
this.type= type;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e("Test", "hello");
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.content_layout, container, false);
TouchImageView imageView = (TouchImageView) view.findViewById(R.id.touchImage);
imageView.setImageResource(R.id.touchImage);
imageView.setMaxZoom(10f);
VideoView videoView =(VideoView) view.findViewById(R.id.videoView1);
if(type.equals("image")) {
imageView.invalidate();
imageView.setVisibility(View.VISIBLE);
videoView.setVisibility(View.GONE);
try {
System.out.println("IN Content Fragment"+imageResourceId.toString());
Bitmap bmp = BitmapFactory.decodeFile(imageResourceId.toString());
imageView.setImageBitmap(bmp);
} catch(Exception e) {
System.out.println("Error Of image File"+e);
}
} else
try {
if(type.equals("video")){
videoView.invalidate();
videoView.setVisibility(View.VISIBLE);
imageView.setVisibility(View.GONE);
String path = imageResourceId.toString();
videoView.setVideoURI(Uri.parse(path));
videoView.setMediaController(new MediaController(getActivity()));
videoView.setFocusable(true);
videoView.start();
}
} catch(Exception e) {
e.printStackTrace();
}
return view;
}
}
这是寻呼机适配器活动
public class MediaActivity extends FragmentActivity {
private MyAdapter mAdapter;
private ViewPager mPager;
public ArrayList<Content> contentList;
Context context;
LinearLayout numberOfPageLayout;
SharedPreferences sharedPreferences;
Handler progressHandler;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_media);
context=(Context) getApplicationContext();
mPager = (ViewPager) findViewById(R.id.pager);
progressHandler = new Handler();
contentList=new ArrayList<Content>();
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
contentList=new ContentDBAdapter(context).getAllContent();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
mAdapter = new MyAdapter(getSupportFragmentManager(),contentList);
mPager.setAdapter(mAdapter);
}
}.execute();
mPager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(int arg0) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
}
public static class MyAdapter extends FragmentPagerAdapter {
ArrayList <Content>contList=new ArrayList<Content>();
public MyAdapter(FragmentManager fm,ArrayList<Content> cont) {
super(fm);
this.contList=cont;
}
@Override
public int getCount() {
totalPage=contList.size();
return contList.size();
}
@Override
public Fragment getItem(int position) {
Content con=contList.get(position);
return new ContentFragment(con.getPath(),con.getType());
}
}
}
