【问题描述】：
我被推荐Harism page curl 在操作栏中实现它 tabs.因为我认为这是唯一应该满足我的要求的东西。
-
下面我展示了输出到目前为止我得到了什么。
我需要在 Viewpager 中添加分页器卷曲。以便操作栏选项卡 将随着卷曲页面滑动。
下面我贴出与此相关的代码。
MainActivity.java：
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private CurlView mCurlView;
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
@SuppressWarnings("unused")
private Menu optionsMenu;
private MenuItem menuItem;
// Tab titles
private String[] tabs = { "Top Rated", "Games", "Movies" };
@SuppressWarnings("deprecation")
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
int index = 0;
if (getLastNonConfigurationInstance() != null) {
index = (Integer) getLastNonConfigurationInstance();
}
mCurlView = (CurlView) findViewById(R.id.curl);
mCurlView.setPageProvider(new PageProvider());
mCurlView.setSizeChangedObserver(new SizeChangedObserver());
mCurlView.setCurrentIndex(index);
mCurlView.setBackgroundColor(0xFF202830);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME
| ActionBar.DISPLAY_SHOW_TITLE | ActionBar.DISPLAY_SHOW_CUSTOM);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
@Override
public void onPause() {
super.onPause();
mCurlView.onPause();
}
@Override
public void onResume() {
super.onResume();
mCurlView.onResume();
}
@Override
public Object getLastCustomNonConfigurationInstance() {
return mCurlView.getCurrentIndex();
}
/**
* Bitmap provider.
*/
private class PageProvider implements CurlView.PageProvider {
// Bitmap resources.
private int[] mBitmapIds = { R.layout.fragment_top_rated, R.layout.fragment_games,
R.layout.fragment_movies };
@Override
public int getPageCount() {
return 2;
}
private Bitmap loadBitmap(int width, int height, int index) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Log.d("index", String.valueOf(index));
View v = inflater.inflate(mBitmapIds[index], null);
v.measure(MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY),
MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY));
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.draw(c);
return b;
}
@Override
public void updatePage(CurlPage page, int width, int height, int index) {
switch (index) {
// First case is image on front side, solid colored back.
default:
Bitmap front = loadBitmap(width, height, 0);
page.setTexture(front, CurlPage.SIDE_FRONT);
page.setColor(Color.rgb(180, 180, 180), CurlPage.SIDE_BACK);
break;
}
}
}
/**
* CurlView size changed observer.
*/
private class SizeChangedObserver implements CurlView.SizeChangedObserver {
@Override
public void onSizeChanged(int w, int h) {
if (w > h) {
mCurlView.setViewMode(CurlView.SHOW_TWO_PAGES);
mCurlView.setMargins(.1f, .05f, .1f, .05f);
} else {
mCurlView.setViewMode(CurlView.SHOW_ONE_PAGE);
// mCurlView.setMargins(.1f, .1f, .1f, .1f);
}
}
}

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// Top Rated fragment activity
return new TopRatedFragment();
case 1:
// Games fragment activity
return new GamesFragment();
case 2:
// Movies fragment activity
return new MoviesFragment();
}
return null;
}
@Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
我的问题是我需要在 ViewPager 中添加页面卷曲。这样我就可以与 viewpager 一起进行滑动。我不知道该怎么做。但我正在努力得到它。任何建议都非常感谢.谢谢。
