ViewPager实现滑动的Preference页面且带ActionBar 立即下载

直接上代码有时间具体分析：

1、MainActivity.java

public class MainActivity extends FragmentActivity implements
		OnPageChangeListener {

	private int mActionBarOptions;
	private ViewPager mViewPager;

	private View mCustomView;
	private ImageView mScroll1;
	private ImageView mScroll2;

	private ImageView mScroll4;

	@Override
	public void onCreate(Bundle savedInstanceState) {

		setContentView(R.layout.custom_tab_on_top_content);

		mViewPager = (ViewPager) findViewById(R.id.pager);
		// mViewPager
		// .setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
		mViewPager.setAdapter(new PagerAdapter(getSupportFragmentManager(),
				this));
		mViewPager.setOnPageChangeListener(this);
		// 设置页面分隔线
		mViewPager.setPageMargin(6);
		mViewPager
				.setPageMarginDrawable(android.R.drawable.divider_horizontal_bright);

		// 自定义 Tab View，并添加到ActionBar上(未设置DisplayOptions，不会显示）
		mCustomView = LayoutInflater.from(this).inflate(
				R.layout.custom_tab_view, null);
		// getParent().getActionBar().setCustomView(mCustomView);
		getActionBar().setCustomView(mCustomView);

		mScroll1 = (ImageView) mCustomView.findViewById(R.id.scroll_1);

	}

	}
