Viewpager中的WebView处理翻屏手势问题

public class MyWebView extends WebView {
	private float oldX;

	private boolean overScrollLeft = false;

	private boolean overScrollRight = false;

	private boolean isScrolling = false;

	public MyWebView(Context context) {
		super(context);
		this.loadUrl("http://www.baidu.com");
	}

	public MyWebView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		this.loadUrl("http://www.baidu.com");
	}

	public MyWebView(Context context, AttributeSet attrs) {
		super(context, attrs);
		this.setScrollbarFadingEnabled(false);
		this.getSettings().setSupportZoom(true);
		this.getSettings().setBuiltInZoomControls(true);
		this.loadUrl("http://www. baidu.com/");
	}


	@Override
	public boolean onTouchEvent(MotionEvent event) {
				
		int scrollBarWidth = getVerticalScrollbarWidth();

		int viewWidth = computeHorizontalScrollExtent();

		int innerWidth = computeHorizontalScrollRange();
		int scrollBarLeftPos = computeHorizontalScrollOffset();

		int scrollBarRightPos = scrollBarLeftPos + viewWidth - scrollBarWidth;

		Log.d("z","scrollBarRightPos===>"+scrollBarRightPos);
		Log.d("z","innerWidth===>"+innerWidth);
		if (scrollBarRightPos >= innerWidth-10) {
			if(event.getAction()==MotionEvent.ACTION_DOWN){
				oldX=event.getX();
				super.onTouchEvent(event);
