How to create custom gridview (Like matrix structure ) in Android

问题

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);

}

}

This can be achieved by GridLayout and dynamic Cell creation

                text[i].setPadding(50, 25, 10, 25);
                text[i].setOnClickListener(new View.OnClickListener() {

                    int pos = item;

                    public void onClick(View v) {

                        Toast.makeText(getBaseContext(), pos + " Clicked",
                                Toast.LENGTH_SHORT).show();
                    }
                });
                gl.addView(text[i]);
            }
        }

        scrolview.addView(gl);

    }

 }

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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="16dp"
    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"
        android:stretchMode="columnWidth"
        android:verticalSpacing="4dp"
        android:horizontalSpacing="4dp"
        android:gravity="center"
        android:layout_centerInParent="true"
 />


</RelativeLayout>

Good luck !!
