Animation

Create a beautiful animated slide courtesy of Cuberto and modified by SWRevo by adding a sample implementation in a Java project.

Requirements

  • Android 7.0+
  • Java 1.8
  • This library made with kotlin language

Gradle

Add the following to your build.gradle to use:

repositories {
    maven { url 'https://jitpack.io' }
}

dependencies {
    implementation 'com.github.SWRevo:LiquidSwipe:1.0.0'
}

Usage

Add LiquidPager to your xml and use it like you would ViewPager, define in xml:

<id.indosw.liquidswipe_lib.LiquidPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

MainActivity in Kotlin :

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import id.indosw.liquidswipe_lib.LiquidPager
import id.indosw.liquidswipesample.adapter.AdapterKt

class MainActivityKt : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val pager = findViewById<LiquidPager>(R.id.pager)
        pager.adapter = AdapterKt(supportFragmentManager)
    }
}

MainActivity in Java :

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import id.indosw.liquidswipe_lib.LiquidPager;
import id.indosw.liquidswipesample.adapter.AdapterJava;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LiquidPager pager = findViewById(R.id.pager);
        pager.setAdapter(new AdapterJava(getSupportFragmentManager()));
    }
}

Adapter in Kotlin :

import android.os.Bundle
import androidx.fragment.app.Fragment
import androidx.fragment.app.FragmentManager
import androidx.fragment.app.FragmentPagerAdapter
import id.indosw.liquidswipesample.fragment.PageFragmentKt

class AdapterKt(fragmentManager: FragmentManager) : FragmentPagerAdapter(fragmentManager, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT) {
    private val total: Int = 6
    private val data : ArrayList<PageFragmentKt> = ArrayList(total)

    init {
        for (i in 0 until total) {
            val fragment = PageFragmentKt()
            val bundle = Bundle()
            bundle.putInt("POSITION", i+1)
            fragment.arguments = bundle
            data.add(fragment)
        }
    }


    override fun getItem(position: Int): Fragment {
        return data[position]
    }

    override fun getCount(): Int {
        return total
    }
}

Adapter in Java :

import android.os.Bundle;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
import org.jetbrains.annotations.NotNull;
import java.util.ArrayList;

import id.indosw.liquidswipesample.fragment.PageFragmentJava;
import kotlin.jvm.internal.Intrinsics;

public class AdapterJava extends FragmentPagerAdapter {

    private final int total;
    private final ArrayList<PageFragmentJava> data;

    @NotNull
    public Fragment getItem(int position) {
        Fragment obj = data.get(position);
        Intrinsics.checkNotNullExpressionValue(obj, "data[position]");
        return obj;
    }

    public int getCount() {
        return total;
    }

    public AdapterJava(@NotNull FragmentManager fragmentManager) {
        super(fragmentManager, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
        Intrinsics.checkNotNullParameter(fragmentManager, "fragmentManager");
        total = 6;
        data = new ArrayList<>(total);
        int i = 0;

        for(; i < total; ++i) {
            PageFragmentJava fragment = new PageFragmentJava();
            Bundle bundle = new Bundle();
            bundle.putInt("POSITION", i + 1);
            fragment.setArguments(bundle);
            data.add(fragment);
        }
