Android fragments 如何在android中通过FragmentTabHost播放视频

我制作了一个有4个选项卡的应用程序：

视频选项卡，在这个选项卡中，我想播放视频，获取远程url

虚拟实验室

编辑视频

帮助

我制作了MainActivity类，其中使用FragmentTabHost类id作为显示选项卡

public class MainActivity extends FragmentActivity{
    private FragmentTabHost mTabHost;
    private FragmentTabHost mTabHostabove;

    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.activity_main);

        mTabHost = (FragmentTabHost)findViewById(R.id.tabhost);
        mTabHost.setup(this, getSupportFragmentManager(), R.id.tabcontent);

        mTabHost.addTab(mTabHost.newTabSpec("Vedio").setIndicator("Vedio",getResources().getDrawable(R.drawable.ic_launcher)),FragmentTab.class,null);
        mTabHost.addTab(mTabHost.newTabSpec("Virtual Lab").setIndicator("Virtual Lab"),FragmentTab.class,null);
        mTabHost.addTab(mTabHost.newTabSpec("Edit Vedio").setIndicator("Edit Vedio"),FragmentTab.class,null);

        mTabHost.addTab(mTabHost.newTabSpec("Help").setIndicator("Help1"),FragmentTab.class,null);
        mTabHostabove = (FragmentTabHost)findViewById(R.id.tabhostabove);
        mTabHostabove.setup(this, getSupportFragmentManager(), R.id.tabcontent);

        mTabHostabove.addTab(mTabHostabove.newTabSpec("Logo").setIndicator("Logo"),FragmentTab.class,null);
        mTabHostabove.addTab(mTabHostabove.newTabSpec("Vedio Url ").setIndicator("Vedio Url",getResources().getDrawable(R.drawable.ic_launcher)),FragmentTab.class,null);
    }
}

我还创建了FragmentTab类，它扩展了Fragment

以下是代码：

public class FragmentTab extends Fragment {
    private TextView tv;
    private VideoView mVideoView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
                View v = inflater.inflate(R.layout.fragment_layout, container, false);
                tv = (TextView) v.findViewById(R.id.text);
                mVideoView =  (VideoView)v.findViewById(R.id.vedioview);
                tv.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    try {
                        String path1="http://commonsware.com/misc/test2.3gp";
                        MediaController  mc = new MediaController(getActivity());
                        mc.setAnchorView(mVideoView);
                        mc.setMediaPlayer(mVideoView);
                        mVideoView.setMediaController(mc);
                        mVideoView.requestFocus();
                        // mVideoView.setVideoURI(Uri.parse("android.resource://" +getActivity().getApplicationContext().getPackageName() +"/"+R.raw.song));
                        mVideoView.setVideoURI(Uri.parse(path1));
                        mc.show();
                        mVideoView.start();
                    } catch (Exception e) {
                    }  
                }
            });
            String tag = this.getTag();

            if (tag == "Vedio") {
                tv.setText("play vedio");
            }
            if (tag == "Edit Vedio") {
                tv.setText("want to Edit Vedio !!!!!!!");
            }
            if (tag == "Help") {
                tv.setText("do u want help !!!!!!!");
            }

            if (tag == "Virtual Lab") {
                tv.setText("Enter Virtual lab !!!!!!!");
            }

            return v;
        }

        @Override
        public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState); 
        }
    }

我被困在点击视频标签播放视频

如果你能，任何人都能解决它。我已经搜索了3天，但没有找到解决方案。视频声音即将到来，但视频无法播放。

并非所有设备都支持所有视频编解码器

我也有同样的问题：我使用mp4格式，分辨率为1280x720。并非所有设备（如HTC Wildfire S）都支持此视频格式。将分辨率更改为480x360后，所有设备都会显示视频
