I want to create a matrix like gridview say 10x20 matrix

we want to specify the number of rows and column of the View ie 10x20

if the screen is low it should scroll to horizontally and vertically
for example the image below describe the Matrix Gridview
Each cell represent
(0,0) (0,1) etc...
(1,0) (1,1) etc..

How can generate this type of view?
Advance Thanks ....!!!

try this:

GridViewCustomAdapter

import java.util.ArrayList;



import android.app.Activity;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.Button;



public class GridViewCustomAdapter extends BaseAdapter {



    ArrayList<String> items;



    static Activity mActivity;



    private static LayoutInflater inflater = null;



    public GridViewCustomAdapter(Activity activity, ArrayList<String> tempTitle) {

        mActivity = activity;

        items = tempTitle;



        inflater = (LayoutInflater) activity

                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }



    @Override

    public final int getCount() {



        return items.size();



    }



    @Override

    public final Object getItem(int position) {

        return items.get(position);

    }



    @Override

    public final long getItemId(int position) {



        return position;

    }



    @Override

    public View getView(final int position, View convertView, ViewGroup parent) {



        View v = null;



        v = inflater.inflate(R.layout.item, null);



        Button tv = (Button) v.findViewById(R.id.button);

        tv.setText(items.get(position));



        return v;

    }



}

gridview.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:gravity="center"

    android:background="@android:color/white"

    android:orientation="vertical" >



    <GridView

        android:id="@+id/grid_view"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:columnWidth="20dip"

        android:gravity="center"

        android:horizontalSpacing="2dp"

         android:verticalSpacing="2dp"

        android:numColumns="20"

        android:stretchMode="columnWidth" >

    </GridView>



</LinearLayout>

item.xml

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

<Button xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/button"

    android:layout_width="80dip"

    android:layout_height="80dip"

    android:textSize="10sp"

    android:background="@android:color/holo_blue_light"

    android:textColor="@android:color/black"

    android:textStyle="bold" />

GridViewActivity

public class GridViewActivity extends Activity {

private GridView list;

ArrayList<String> data = new ArrayList<>();





@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.gridview);

    for (int i = 0; i < 10; i++) {

        for(int j=0;j<20;j++)

        data.add(i+"-"+j);

    }

    GridViewCustomAdapter adapter = new GridViewCustomAdapter(this, data);



    list = (GridView) findViewById(R.id.grid_view);

    list.setAdapter(adapter);



}

}

output :

This can be achieved by GridLayout and dynamic Cell creation

This is not the straight solution but... i think i need to customize the GridView which i do`nt know currently

hi this is one code that i've created to do one matrix of buttons "x"

package com.example.andre.aplicacaocalibracaov2;



import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.AdapterView;

import android.widget.GridView;

import android.widget.Toast;



import java.util.ArrayList;

import java.util.List;



public class MainActivity extends AppCompatActivity {

    GridView gridView;

    List<String> lstSource = new ArrayList<>();



    String array_caracteres={

      "x"

    };



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        setUpList();

        GridView gridView = (GridView) findViewById(R.id.gridView);

        //é a classe gridadapter

        GridAdapter adapter = new GridAdapter(lstSource,MainActivity.this);

        gridView.setAdapter(adapter);





    }

        public void setUpList() {

            for (String item : array_caracteres)

                for (int i = 0; i < 10; i++) {

                    for (int j = 0; j < 10; j++)

                        lstSource.add(item);

                }

        }

}





GridAdapter.java



package com.example.andre.aplicacaocalibracaov2;



import android.content.Context;

import android.graphics.Color;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.Button;

import android.widget.GridLayout;

import android.widget.GridView;

import android.widget.ImageView;

import android.widget.Toast;



import java.util.List;



public class GridAdapter extends BaseAdapter {



    private Context context;

    List<String> lstSource;



    public GridAdapter(List<String>lstSource, Context context){

        this.lstSource = lstSource;

        this.context=context;





    }

    @Override

    public int getCount() {



        return lstSource.size();

    }



    @Override

    public Object getItem(int position) {



        return lstSource.get(position);

    }



    @Override

    public long getItemId(int position) {

        return position;

    }



    @Override

    public View getView(int position, View convertView, ViewGroup parent) {

        final Button button;

        if(convertView ==null){

            button = new Button(context);

            button.setLayoutParams(new GridView.LayoutParams(85,85));

            button.setPadding(8,8,8,8);

            button.setText(lstSource.get(position));

            button.setBackgroundColor(Color.YELLOW);

            button.setOnClickListener(new View.OnClickListener(){

                public void onClick(View v){

                    Toast.makeText(context,button.getText().toString(),Toast.LENGTH_SHORT).show();

                }

            });





        }

        else

            button=(Button)convertView;

        return button;

    }

}

the xml

<?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"

    android:paddingLeft="16dp"

    android:paddingRight="16dp"

    android:paddingBottom="16dp"

    tools:context=".MainActivity"



    >



    <GridView

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:id="@+id/gridView"

        android:columnWidth="30dp"

        android:numColumns="auto_fit"

</RelativeLayout>

Good luck !!
