【Android|Android SlidingTabLayout用法&禁止ViewPager滑动】Android 提供的API例子程序中有个自定义View，SlidingTabLayout+SlidingTabStrip，两者结合构造完美可滑动Tab
主要代码

import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.view.PagerAdapter; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import com.example.android.common.logger.Log; import com.example.android.common.view.CustomViewPager; import com.example.android.common.view.SlidingTabLayout; public class SlidingTabsBasicFragment extends Fragment {static final String LOG_TAG = "SlidingTabsBasicFragment"; private SlidingTabLayout mSlidingTabLayout; private CustomViewPager mViewPager; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_sample, container, false); }@Override public void onViewCreated(View view, Bundle savedInstanceState) { mViewPager = (CustomViewPager) view.findViewById(R.id.viewpager); mViewPager.setAdapter(new SamplePagerAdapter()); mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs); mSlidingTabLayout.setViewPager(mViewPager); mViewPager.setCanPageScroll(false); }class SamplePagerAdapter extends PagerAdapter {/** * @return the number of pages to display */ @Override public int getCount() { return 10; }@Override public boolean isViewFromObject(View view, Object o) { return o == view; } @Override public CharSequence getPageTitle(int position) { return "Item " + (position + 1); }@Override public Object instantiateItem(ViewGroup container, int position) { View view = getActivity().getLayoutInflater().inflate(R.layout.pager_item, container, false); TextView title = (TextView) view.findViewById(R.id.item_title); title.setText(String.valueOf(position + 1)); container.addView(view); return view; }@Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView((View) object); Log.i(LOG_TAG, "destroyItem() [position: " + position + "]"); }} }

CustomViewPager

package com.example.android.common.view; import android.content.Context; import android.support.v4.view.ViewPager; import android.util.AttributeSet; import android.view.MotionEvent; import android.view.ViewConfiguration; public class CustomViewPager extends ViewPager {private boolean isCanPageScroll = true; private int scaledTouchSlop = 0; private float startX = 0f; private float startY = 0f; public CustomViewPager(Context context) { this(context,null); }public CustomViewPager(Context context, AttributeSet attrs) { super(context, attrs); scaledTouchSlop = ViewConfiguration.get(context).getScaledPagingTouchSlop(); }public void setCanPageScroll(boolean isCanScroll){ this.isCanPageScroll = isCanScroll; }@Override public boolean onTouchEvent(MotionEvent ev) { if(!isCanPageScroll && interceptTouchEvent(ev)) { return true; } returnsuper.onTouchEvent(ev); }/** * 判断是否拦截滑动 * @param ev * @return */ private boolean interceptTouchEvent(MotionEvent ev) { float curX = ev.getX(); float curY = ev.getY(); switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: startX = curX; startY = curY; break; case MotionEvent.ACTION_MOVE: if(Math.abs(curY-startY)=scaledTouchSlop) { return true; } break; case MotionEvent.ACTION_UP: case MotionEvent.ACTION_CANCEL: startX = 0f; startY = 0f; break; } return false; }}
