Button Click Me setOnClickListener Method Working — Java Android

Button will respond to OnClickListener after this course.

This example demonstrates the implement button onclicklistener android java Code Example

In this article, we will discuss about how to trigger click events on android Views (Buttons, Text views etc) ?

Android Button in JAVA ANDROID

Action listeners are probably the easiest — and most common — event handlers to implement. You implement an action listener to define what should be done when an user performs certain operation.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

How to implement on Android Button OnClick in android programmatically.

Step 2 — “Add the following code to res/layout/activity_main.xml.“

I worked in simple relative layout method for only give basic example.

• In the below code, we have declared Button as ”@+id/button”.
• You can add a spinner to your layout with the Button object. You should usually do so in your XML layout with a <Button> element. For example:

RELATIVE LAYOUT FILE CODE IN XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
         xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         tools:context="com.yourname.yourpackagename.MainActivity"
         android:padding="16dp"
         android:id="@+id/relLayout"
         android:orientation="vertical">
<Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_centerHorizontal="true"
           android:layout_centerVertical="true"
           android:text="Click Me" />

   <TextView
        android:id="@+id/textView"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginBottom="100dp"
           android:layout_centerVertical="true"
           android:layout_centerHorizontal="true"
            android:layout_above="@+id/button"
           android:textStyle="bold"/>
</RelativeLayout>

Step 3: MainActivity.java” java file − Add the following code to src/MainActivity.java

JAVA CODE IN MAIN ACTIVITY:

package com.yourname.yourpackagename;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

   Button button;
   TextView textView;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);


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

                 textView = (TextView) findViewById(R.id.textView);


                 button.setOnClickListener(new View.OnClickListener() {
            @Override
               public void onClick(View v) {
                               textView.setText("button.setOnClickListener(new View.OnClickListener() code is working");
                           }
        });

   }

}

Review Application

The event is a very important part of any application which makes it user intractable. It may be generated when we click on any view in Android. To trigger click events on any view, we have OnClickListners.
