自定义ViewPager，避免左右滑动时与水平滑动控件冲突

import android.content.Context;import android.support.v4.view.ViewPager;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.View;

public class CanScrollViewPager extends ViewPager {  private boolean mNoScroll = false;//标记不允许左右滚动

  /**   * @param context   * @param attrs   */  public CanScrollViewPager(Context context, AttributeSet attrs) {    super(context, attrs);  }

  /**   * @param context   */  public CanScrollViewPager(Context context) {    super(context);  }

  @Override  protected boolean canScroll(View v, boolean checkV, int dx, int x, int y) {    if (v != this && (v instanceof PageWebView || v instanceof HorizontalGalleryView)) {      requestDisallowInterceptTouchEvent(true);      return true;    }    return super.canScroll(v, checkV, dx, x, y);  }

  @Override  public boolean dispatchTouchEvent(MotionEvent ev) {    switch (ev.getAction()) {      case MotionEvent.ACTION_UP:      case MotionEvent.ACTION_CANCEL:        break;      default:        break;    }    return super.dispatchTouchEvent(ev);  }

  //设置不允许左右滚动  public void setNoScroll(boolean noScroll) {    this.mNoScroll = noScroll;  }

  @Override  public boolean onTouchEvent(MotionEvent arg0) {    if (mNoScroll) {      return false;    }    return super.onTouchEvent(arg0);  }

  @Override  public boolean onInterceptTouchEvent(MotionEvent arg0) {    if (mNoScroll) {      return false;    }

    return super.onInterceptTouchEvent(arg0);  }}
