Android fragments Android代码的刷新按钮，破坏和重新创建文本媒体播放器（挂起）！

viewPager4片段活动

如果我点击播放短声音的文本，一个接一个，那么有时mediaplayer会挂起，不播放任何声音。但如果我能够用操作栏中的刷新按钮销毁活动并重新创建相同的活动，我就可以再次单击声音

那么在代码中为

R.id.item2

写些什么呢

或者有没有其他方法可以让这些文本连续点击短音而不会出现任何问题

参考代码如下：

public class module1 extends FragmentActivity {
static Context con;
static int length = 0;
ViewPager mViewPager;
SectionsPagerAdapter mSectionsPagerAdapter;
static MediaPlayer mediaplayer, mediaplayert, m;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    con = this;
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);       
}   

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.mains, menu);
    //  Just .main into .mains [created new for different behavior of Action Bar]       
    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == R.id.item1) {
        Intent in = new Intent(Intent.ACTION_VIEW,
                Uri.parse("http://www.google.com"));
        startActivity(in);
    }   
    if (item.getItemId() == R.id.item2) {


        //what should i write here? to destroy and recreate the same fragment activity again.
        //Problem: After clicking fast on one after another text links, mediaplayert hangs and doesnt play
        //Solution: exit app destroy and reopen, then mediaplayer works fine... 
        //SO, what to write here? kindly help!


        }

        return super.onOptionsItemSelected(item);
}
