GridView dose not show all items in a wrap_content height Linearlayout

Question

[SOVLED]

The Solution for those need : replace the Gridview with Recyclerview and use this method to calculate the "auto_fit" rows for Gridview . set Gridview item layout size to wrap_content with attribute adjustViewBounds="true" for the images.

 public int calculateNoOfColumns(Context context) {
        DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
        float dpWidth = displayMetrics.widthPixels / displayMetrics.density;
        int noOfColumns = (int) (dpWidth / 180);
        return noOfColumns;
    }

The problem is when I set the wrap_content height for the LinearLayout, the GridView doesn't show all items ( just a half ). It works if the layout_height is match_parent, but each item will have a lot of space. (I use recyclerview with HasFixedSize(true). the GridView will show all items if height and width are fixed size

This is the Layout contains Recyclerview :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".Activities.Chat">

//APPBAR LAYOUT HERE. BUT DOES NOT MATTER

    <android.support.design.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:background="@color/white"
        android:fitsSystemWindows="true"
        android:layout_height="match_parent">

            <android.support.v7.widget.RecyclerView
                android:layout_width="match_parent"
                android:scrollbars="none"
                app:stackFromEnd="true"
                android:background="@color/white"
                android:layout_height="match_parent">

            </android.support.v7.widget.RecyclerView>

    </android.support.design.widget.CoordinatorLayout>

   //SOME VIEWS HERE BUT NOT IMPORTANT

</RelativeLayout>

this is the code of RecyclerView

mLayoutManager =new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false);
mLayoutManager.setStackFromEnd(true);
Recycler.setHasFixedSize(true);
Recycler.setLayoutManager(mLayoutManager);
Recycler.setAdapter(Adapter);
Recycler.setItemAnimator(null);

this is the RecyclerView Item :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="right"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:orientation="vertical"
    android:padding="5dp"
    xmlns:android="http://schemas.android.com/apk/res/android">

   //more views here but not important

this is the grid view item and grid view adapter

<?xml version="1.0" encoding="utf-8"?>

try this one:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:orientation="vertical"
    android:padding="5dp"
    xmlns:android="http://schemas.android.com/apk/res/android">

MORE VIEWS HERE BUT IT DOES NOT MATTER.

It seems that your GridView was empty in code you've pasted. Images you said supposed to be in it, was outside of closing tab.
