How to remove onClickListener for a view in android?
In some situations, We should not allow onClickListener for a view. This example demonstrates how to remove onClickListener for a view in android.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/acitivity_main.xml.
<?xml version = "1.0" encoding = "utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:id = "@+id/parent" xmlns:tools = "http://schemas.android.com/tools" android:layout_width = "match_parent" android:layout_height = "match_parent" tools:context = ".MainActivity" android:gravity = "center" android:orientation = "vertical"> <TextView android:id = "@+id/text" android:textSize = "28sp" android:textAlignment = "center" android:layout_width = "match_parent" android:layout_height = "wrap_content" /> </LinearLayout>
In the above code, we have taken a text view, In this example, we should remove onClickListner for this text view.
Step 3 − Add the following code to src/MainActivity.java
package com.example.andy.myapplication;
import android.content.res.Configuration;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int view = R.layout.activity_main;
TextView textview;
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(view);
textview = findViewById(R.id.text);
textview.setText("There is no Click listner for text view");
textview.setOnClickListener(null);
}
}In the above example, we are passing a null value to setOnClickListener(), so it will don't perform any action when a user clicks on the text view.
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run 
icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
In the above screen click on text view, it will show nothing because we have sent a null value for setOnClickListener().
