1、不能左右滑动的ViewPager

/*
 * Date: 14-7-28
 * Project: Access-Control-V2
 */
package cn.irains.access.v2.common;

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

/**

 * Time: 14-7-28 上午10:20
 */
public class StaticViewPager extends ViewPager {
    public StaticViewPager(Context context) {
        super(context);
    }

    public StaticViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        return false;
    }

    @Override
    public void setCurrentItem(int item) {
        this.setCurrentItem(item, false);
    }
}

2、高度可以为WrapContent的ViewPager

/*
 * Date: 14-8-18
 * Project: Access-Control-V2
 */
package cn.irains.access.v2.common;

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

/**
 * Author: msdx (645079761@qq.com)
 * Time: 14-8-18 上午11:22
 */
public class WrapHeightViewPager extends ViewPager {
    public WrapHeightViewPager(Context context) {
        super(context);
    }

    public WrapHeightViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int height = 0;
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if (h > height) height = h;
        }

        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    /**
     * Determines the height of this view
     *
     * @param measureSpec A measureSpec packed into an int
     * @param view        the base view with already measured height
     * @return The height of the view, honoring constraints from measureSpec
     */
    private int measureHeight(int measureSpec, View view) {
        int result = 0;
        int specMode = MeasureSpec.getMode(measureSpec);
        int specSize = MeasureSpec.getSize(measureSpec);

        if (specMode == MeasureSpec.EXACTLY) {
            result = specSize;
        } else {
            // set the height from the base view if available
            if (view != null) {
                result = view.getMeasuredHeight();
            }
            if (specMode == MeasureSpec.AT_MOST) {
                result = Math.min(result, specSize);
            }
        }
        return result;
    }

}
