Hello everyone ,

Our next Example in Basic Android Examples is Basic Toast Example . In this post we will create a Button on click of which you ll be able to see a notification on Mobile screen which is known as Toast .

So basically , what is a toast ?

It is actually like an alert message. android.widget.Toast class used to create toast alert message.

Uses :

1. Toast alert is a notification message that display for certain amount of time, and automtaically fades out after set time.

2. Use it to show alert message to user.

3. can use it for debugging your application.

4.to show alert from background sevice,boadcast reciever,getting data from server...etc.

Let us start with the code :

Step 1: Create a New Application

Let us first create a new Application/Project . I named it as Toast Example.

Android Example

Step 3:Activity

Now add a new buuton either by dragging in activity_toast.xml or by writing the code . I changed the text of button as Toast Example .

Android Toast Example

Step 3: Add a New Button

For Activity java class first we need to get the Button id using findIdbyView method and then we override the onclicklistener method onClick with which a Toast with the String inside it and length defined will be shown on the mobile screen .

package javainhouse.com.toastexample;

import android.content.Context;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.Gravity;

import android.view.LayoutInflater;

import android.view.View;

import android.widget.Button;

import android.widget.Toast;

public class ToastActivity extends AppCompatActivity {

private Button toastExample;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_toast);

toastExample = (Button) findViewById(R.id.buttonToast);

// Button click listner

toastExample.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Context context = getApplicationContext();

// Toast toast = new Toast(context);

Toast.makeText(getApplicationContext(),

"Hello Toast", Toast.LENGTH_LONG)

.show();

}

});

}

Step 4: Output

Android Studio - ListView Basic Example

in Android, Android Example, Basic, ListView - on 13:13:00 - No comments

Hello people,

Its been a quite time that there has been no post regarding Android Examples on this blog. So Today we are going to write a very basic program
which is To display a list view in Android . We are going to use Android Studio for this Example too, as most of our previous examples were also in Android Studio.
So before I explain you more about Android Studio without wasting more of your time ,let us dig in the code .

So the very first question in your mind (if you are new in android ) would be what the hell is listview? Is it a collection like in Java?
No sorry it is not related to Collections in Java.

ListView is actually just a group of some items ,which can be scrolled in vertical position .For Example as you go into Settngs of your phone
you see a list of items like Network , Wifi, Bluetooth and many more in a vertical scrollable way.

So from does this ListView came from ? I mean you are wondering who's the father? :D
ListView and GridView are siblings with father Mr. AdapterView ... View is their SirName :p

I mean that both ListView and GridView are subclasses of AdapterView . So i shall not go into more details of their family and let me show a very basic example of
listView . In this example i ll just show a list of items and on clicking any of them u ll get a toast which show their name Thats it . Seems to be easy right ?
Its not too difficult but yes we have to write the whole code . :)

Step 1: Create a New Application

Let us first create a new Application in Android Studio.

Android ListView Example

Android Example

I gave Application name as ListViewExample .You can provide any values to the form Configure your project. and click Next.

Step 2: Select Target Android Device

Select Target Android Device on which output will be shown . For this I choose Phone View.

Step 3: Customize the Activity

By Default the activity name is MainActivity . If you want to change that you can but rest of the things will be changed accordingly. I gave name as ListViewActivity

Android Example

Step 4:

After your Application is created you ll see the screen below with 3 main files :

1.*xxx*Activity.java
2. content_xxx.xml
3. activity_xxx.xml

xxx is will be the name which you choose in step 3.

Android Example

If you are wondering that there are two xml files content_listview.xml and activity_listview.xml and in which I should write the code then I tell you that you can add your widget or container in any xml file as content_list.xml is a part of activity_listview.xml only.

Activity_listview.xml

Android Example

Step 5:

Now you need to add listview in xml file . I added it in content_listview.xml. You can add it in 2 ways :

1. Simply Drag listview container from left Explorer as shown in below screenshot :

Android Example

2. Second way is to add list view tag in content_listview.xml file as shown below :

Android Example

Step 6: Create a new activity.I named it as Button Activity

Now we need to add code in ListViewActivity.Java .For List Items we are using a String Array .

First , we need to Retrieve the ListView using method findViewById. where listView is the id we gave while creating list view in content_listview.xml.

final ListView listView = (ListView) findViewById(R.id.listView);

Second, Define a new Adapter and assign that adapter to the listView variable we created above.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1, values);


        

listView.setAdapter(adapter);

Then , we have to define the onlick listener of listView which will run when user click on any of the item .In this code On Click of item a Toast is shown with item position no. and value of that item.

You can find below the whole ListViewActivity.java.

package javainhouse.com.listviewexample;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class ListviewActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_listview);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        // Get ListView object from xml
       final ListView listView = (ListView) findViewById(R.id.listView);

        // Defined Array values to show in ListView
        String[] values = new String[] { "List View Item1",
                "List View Item 2",
                "List View Item 3",
                "List View Item 4",
                "List View Item 5",

        };
        
        // Define a new Adapter
       

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1, values);


        // Assign adapter to ListView
        listView.setAdapter(adapter);

        // ListView Item Click Listener
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener()   {


            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {

                // ListView Clicked item index
                int itemPosition     = position;

                // ListView Clicked item value
                String  itemValue    = (String) listView.getItemAtPosition(position);

                // Show Alert
                Toast.makeText(getApplicationContext(),
                        "Position :"+itemPosition+"  ListItem : " +itemValue , Toast.LENGTH_LONG)
                        .show();

            }

        });
    }






    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_listview, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

Step 7: RUN and Output
