Android Development Tips--viewpager derived from the 2 classes

1, can not be left and right sliding 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;/** * AUTHOR:MSDX ([email protected]) * time:14-7-28 morning 10:20 */public class Staticviewpager extends Viewpager {public    Sta Ticviewpager (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, the height can be wrapcontent 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 ([email protected]) * time:14-8-18 morning 11:22 */public class Wrapheightviewpager extends Viewpager {public Wra    Pheightviewpager (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 to an int * @p Aram View the base view with already measured height * @return The height of the view, honoring constraints fro        M 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; }}
