Grid View with text in android/Grid View Example in android/ Simple grid View in android

Using grid View we can display items in two dimensional, scrollable grids. Grid view can be used in many ways. We can display text using grid view (very simple when compared to other grid view).

First create a project and name it as you like. Then go to the main.xml file (I think you may now familiar with xml and other application resource stuffs). Then open the graphic layout, select composite and drag “Grid View” in to the page. Quite simple, right?? The code look like this..

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridView1"
    android:numColumns="auto_fit"
    android:gravity="center"
    android:columnWidth="50dp"
    android:stretchMode="columnWidth"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

</GridView>


Now open your main activity. Then make a string array which holds some text. For eg,

static final String[] numbers = new String[] { 
                          "A", "B", "C", "D", "E",
                          "F", "G", "H", "I", "J",
                          "K", "L", "M", "N", "O",
                          "P", "Q", "R", "S", "T",
                          "U", "V", "W", "X", "Y", "Z"};

Then in onCreate method, create the object of Grid View and then create the instance of Array Adapter as we did in List View

GridView gridView = (GridView) findViewById(R.id.gridView1);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                   android.R.layout.simple_list_item_1, numbers);

Then call the method

gridView.setAdapter(adapter)

Add an onclicklistener to perform any action while clicking on each item of the grid view

 
                 gridView.setOnItemClickListener(new OnItemClickListener() {
                          public void onItemClick(AdapterView<?> parent, View v,
                                   int position, long id) {
                             Toast.makeText(getApplicationContext(),
                                   ((TextView) v).getText(), Toast.LENGTH_SHORT).show();
                          }
                 });



Now you can run the application

The entire code will look like this..

main.xml


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


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


android:id="@+id/gridView1"


android:numColumns="auto_fit"


android:gravity="center"


android:columnWidth="50dp"


android:stretchMode="columnWidth"


android:layout_width="fill_parent"


android:layout_height="fill_parent" >




</GridView>


GridViewActivity.java

package com.GridviewExample.android;
 
import android.app.Activity;
import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.TextView;
import android.widget.Toast;
import android.view.View;
import android.widget.AdapterView.OnItemClickListener;
 
public class GridViewActivity extends Activity {
 
         GridView gridView;
 
         static final String[] numbers = new String[] { 
                          "A", "B", "C", "D", "E",
                          "F", "G", "H", "I", "J",
                          "K", "L", "M", "N", "O",
                          "P", "Q", "R", "S", "T",
                          "U", "V", "W", "X", "Y", "Z"};
 
         @Override
         public void onCreate(Bundle savedInstanceState) {
                 super.onCreate(savedInstanceState);
 
                 setContentView(R.layout.main);
 
                 gridView = (GridView) findViewById(R.id.gridView1);
 
                 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                   android.R.layout.simple_list_item_1, numbers);
 
                 gridView.setAdapter(adapter);
 
                 gridView.setOnItemClickListener(new OnItemClickListener() {
                          public void onItemClick(AdapterView<?> parent, View v,
                                   int position, long id) {
                             Toast.makeText(getApplicationContext(),
                                   ((TextView) v).getText(), Toast.LENGTH_SHORT).show();
                          }
                 });
 
         }
 
}

Custom Spinner in Android

Custom Spinner in Android/Spinner using custom adapter/spinner with icon and text  In this tutorial, i'll show you to customizing spinner in different methods.  To change the normal display of spinner view, add background image using the code " android:background="@drawable/myspinner_background" in the xml. You can also make it customizable by setting up an xml file in drawable folder Custom display with icon in the spinner   main.xml <? xml version = "1.0" encoding = "utf-8" ?> < LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"     android:orientation = "vertical"     android:layout_width = "fill_parent"     android:layout_height = "fill_parent"     >     < Spinner     android:drawSelectorOnTop = "true"     android:id = "@+id/spinner1"     android:layout_width = "match_parent"     android:layout_height = "wrap_content&

Coroutine- A complete tutorial

 What are coroutines? To know about coroutine, first you need to know about asynchronous programming, thread and multithreading concept. What is a thread? Thread describes in which context the function or sequence of instructions should be executed. So, every block of code or functions runs in a thread, right? Also, you can load multiple threads to perform different block of codes  How to start a thread? Thread thread = new Thread(){     public void run(){       System.out.println("This is a thread");     }   }     thread.start(); So when coming to android, before learning about coroutines we need to discuss some scenarios. Normally how an app works when user launch an application. When user launchers the application, a main thread is created. This thread is intended to do small operations like button clicks, UI interaction , small mathematical operations. We cant perform long running operation like file download, database queries, network operations and image
