关于ViewPager高度自适应（随着pager页的高度改变Viewpager的高度）

package com.xx.xxxx.views;  import android.content.Context;  import android.os.Build;  import android.support.v4.app.Fragment;  import android.support.v4.view.ViewPager;  import android.util.AttributeSet;  import android.util.TypedValue;  import android.view.MotionEvent;  import android.view.View;  import android.widget.LinearLayout;  import java.util.ArrayList;  import java.util.HashMap;  import java.util.LinkedHashMap;  import java.util.List;  import java.util.Map;  /**  * Created by vipui on 16/8/25.  */  public class CustomViewpager extends ViewPager {      private int current;      private int height = 0;      /**      * 保存position与对于的View      */      private HashMap<Integer, View> mChildrenViews = new LinkedHashMap<Integer, View>();      private boolean scrollble = true;      public CustomViewpager(Context context) {          super(context);      }      public CustomViewpager(Context context, AttributeSet attrs) {          super(context, attrs);      }      @Override      protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {          if (mChildrenViews.size() > current) {              View child = mChildrenViews.get(current);              child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));              height = child.getMeasuredHeight();          }          heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);          super.onMeasure(widthMeasureSpec, heightMeasureSpec);      }      public void resetHeight(int current) {          this.current = current;          if (mChildrenViews.size() > current) {              LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) getLayoutParams();              if (layoutParams == null) {                  layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, height);              } else {                  layoutParams.height = height;              }              setLayoutParams(layoutParams);          }      }      /**      * 保存position与对于的View      */      public void setObjectForPosition(View view, int position)      {          mChildrenViews.put(position, view);      }      @Override      public boolean onTouchEvent(MotionEvent ev) {          if (!scrollble) {              return true;          }          return super.onTouchEvent(ev);      }      public boolean isScrollble() {          return scrollble;      }      public void setScrollble(boolean scrollble) {          this.scrollble = scrollble;      }  }  

setObjectForPosition（）方法中是为了调用存放你的view和他对应的position，这个是参考了鸿洋大神的一篇文章，链接：http://blog.csdn.net/lmj623565791/article/details/38026503，为了防止预加载导致的高度不匹配，我们加自身的fragment和position对应起来放在linkedmap里。
好了，剩下的就是调用
setObjectForPosition（）这个方法了，请看我的一个fragment
