督促学习——ViewPager实现滑动的Preference页面且带ActionBar

本文主要是介绍督促学习——ViewPager实现滑动的Preference页面且带ActionBar，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

直接上代码有时间具体分析：

1、MainActivity.java

public class MainActivity extends FragmentActivity implementsOnPageChangeListener {private int mActionBarOptions;private ViewPager mViewPager;private View mCustomView;private ImageView mScroll1;private ImageView mScroll2;private ImageView mScroll3;private ImageView mScroll4;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(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);mScroll2 = (ImageView) mCustomView.findViewById(R.id.scroll_2);mScroll3 = (ImageView) mCustomView.findViewById(R.id.scroll_3);mScroll4 = (ImageView) mCustomView.findViewById(R.id.scroll_4);}@Overrideprotected void onResume() {super.onResume();ActionBar actionBar = getActionBar();mActionBarOptions = actionBar.getDisplayOptions();// 设置DisplayOptions，显示ActionBar自定义的ViewactionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM,ActionBar.DISPLAY_SHOW_CUSTOM | mActionBarOptions);setCurrentScroll(mViewPager.getCurrentItem());}@Overrideprotected void onPause() {super.onPause();getActionBar().setDisplayOptions(mActionBarOptions,ActionBar.DISPLAY_SHOW_CUSTOM | mActionBarOptions);}public void onTabClick(View view) {Log.d("TAG", "onTabClick" + view.getId());switch (view.getId()) {case R.id.tab_text_1:mViewPager.setCurrentItem(0, false);break;case R.id.tab_text_2:mViewPager.setCurrentItem(1, false);break;case R.id.tab_text_3:mViewPager.setCurrentItem(2, false);break;case R.id.tab_text_4:mViewPager.setCurrentItem(3, false);break;}}private void setCurrentScroll(int selection) {if (mScroll1 != null && mScroll2 != null && mScroll3 != null&& mScroll4 != null) {mScroll1.setVisibility(selection == 0 ?
