滑动活动反对碎片

Question

我有一个包含5个不同片段的活动，您可以轻扫。我想知道如何在5个不同的活动类中刷卡。

以下是滑动片段的代码：

public class MainActivity extends FragmentActivity {
    private PageAdapter mPagerAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.viewpager_layout);
        initialisePaging();

    }

    private void initialisePaging() {
        // TODO Auto-generated method stub
        List<Fragment> fragments = new Vector<Fragment>();
        fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment3.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment4.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment5.class.getName()));


        mPagerAdapter = new PageAdapter(this.getSupportFragmentManager(), fragments);
        ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
        pager.setAdapter(mPagerAdapter);

    }

    @Override
     public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        onBackPressed();

    }

    return super.onKeyDown(keyCode, event);
    }
    @Override
    public void onBackPressed() {
       Log.d("CDA", "onBackPressed Called");
       Intent intent = new Intent(this, MoodActivity.class);
       startActivity(intent);
    }
