Android add pictures to ListView or Recyclerview display _android

First picture.

Click on the + number to select the picture

In fact, the addition itself is a ListView or Recyclerview

It's just a little special layout.

In adpater to determine whether a data is 0 and is not the last to add a picture on it.

 @Override public
 int GetItemCount () {
  if (Mdatas = null | | mdatas.size () = = 0) {return
   1;
  } else if (mDa Tas.size () < Mmaxnum) {return
   mdatas.size () + 1;
  } else {return
   mdatas.size ();
 }}

Here we use a square, a container.

Package Liu.myrecyleviewchoosephoto.view;
Import Android.content.Context;
Import Android.util.AttributeSet;

Import Android.widget.RelativeLayout; /** * Square relativelayout * Created by Liu Nan on 2016/8/13 0013.16:07/public class Squarerelativelayout extends Relativel

 TTR); @Override protected void onmeasure (int widthmeasurespec, int heightmeasurespec) {//set its own measurement results setmeasureddimensi


  On (Getdefaultsize (0,widthmeasurespec), Getdefaultsize (0,heightmeasurespec));
  /** * Measuring the * * int childwidthsize=getmeasuredwidth () of the child view;
