Swipeable and Non-Swipeable ViewPager in Android

Post Views: 7,452

Hello Friends, recently I was developing a mobile application in which I had to make Swipeable and Non-Swipeable ViewPager in Android and to achieve this I had to create ViewPager subclass CustomViewPager class . So, I thought to share it so that anyone else required can use it. I’d created a separate test application to share and you can also download Android Studio Project, Download link is available at the end of this post.

So, Here is the code

CustomViewPager.java

package com.zatackcoder.swipeablenonswipeableviewpager;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class CustomViewPager extends ViewPager {

    boolean swippable = true;

    public CustomViewPager(@NonNull Context context) {
        super(context);
    }

    public CustomViewPager(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if(swippable){
            return super.onInterceptTouchEvent(event);
        }
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        if(swippable){
            return super.onTouchEvent(event);
        }
        return false;
    }

    public void setSwipeable(boolean swippable) {
        this.swippable = swippable;
    }
}

package com.zatackcoder.swipeablenonswipeableviewpager;

import android.content.Context;

import android.support.annotation.NonNull;

import android.support.annotation.Nullable;

import android.support.v4.view.ViewPager;

import android.util.AttributeSet;

import android.view.MotionEvent;

public class CustomViewPager extends ViewPager {

boolean swippable = true;

public CustomViewPager(@NonNull Context context) {

super(context);

}

public CustomViewPager(@NonNull Context context, @Nullable AttributeSet attrs) {

super(context, attrs);

}

@Override

public boolean onInterceptTouchEvent(MotionEvent event) {

if(swippable){

return super.onInterceptTouchEvent(event);

}

return false;

}

@Override

public boolean onTouchEvent(MotionEvent event) {

// Never allow swiping to switch between pages

if(swippable){

return super.onTouchEvent(event);

}

return false;

}

public void setSwipeable(boolean swippable) {

this.swippable = swippable;

}
