Slide Image in RecyclerView

Mục đích của bài viết là hướng dẫn cách tạo 1 slide image trong item của recycler view

1. Model, data, view, interface

1.1. Tạo model Profile

Tạo 1 model chứa thông tin Profile : gồm id, name, age, và list image

package tuananh.com.slideimageinrecyclerview.model;

import java.io.Serializable;
import java.util.List;

/**

 */
public class Profile implements Serializable {
    private int mId;
    private String mName;
    private int mAge;
    private List<String> mImageList;

    public Profile(int id, String name, int age, List<String> imageList) {
        mId = id;
        mName = name;
        mAge = age;
        mImageList = imageList;
    }

    public int getId() {
        return mId;
    }

    public void setId(int id) {
        mId = id;
    }

    public String getName() {
        return mName;
    }

    public void setName(String name) {
        mName = name;
    }

    public List<String> getImageList() {
        return mImageList;
    }

    public void setImageList(List<String> imageList) {
        mImageList = imageList;
    }

    public int getAge() {
        return mAge;
    }

    public void setAge(int age) {
        mAge = age;
    }

    public String getNameAge() {
        return String.format("%s, %d", getName(), getAge());
    }
}

1.2. View custom

1.2.1. CircleIndicator

Vẽ và bắt sự kiện scroll viewpage và vẽ lại vị trí của ảnh tương ứng trong list image

Tạo Adapter cho slide image là SlideImageAdapter Hàm khởi tạo cần truyền profile và listener onClickShowImageListener ( mục đích là bắt sự kiện OnClickListener vào ảnh để sang trang show full image) public SlideImageAdapter(Context context, Profile profile, OnClickShowImageListener onClickShowImageListener) { }

2.1.2. Layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

    <data>

        <variable
            name="position"
            type="int"/>

        <variable
            name="url"
            type="String"/>

    </data>

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white">

        <ImageView
            android:id="@+id/image_slide"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            app:imageUrl="@{url}"/>
    </FrameLayout>
</layout>

2.2. ProfileAdapter

2.2.1. Tạo adapter ProfileAdapter cho reycerview

Function public void bind(Profile profile) {}

  • mBinding.setVariable(BR.viewModel, profile); -> truyền data và trong layout
  • SlideImageAdapter slideImageAdapter = new SlideImageAdapter(mContext, profile, mOnClickShowImageListener); -> khởi tạo slideImageAdapter cho viewpager trong mỗi item của recyclerview
  • mBinding.slideImageViewPager.setAdapter(slideImageAdapter); -> truyền adapter vào viewpager
  • mBinding.slideImageViewPager.setOffscreenPageLimit(MAX_SIZE_IMAGE_LOAD); -> load tối đa MAX_SIZE_IMAGE_LOAD ảnh ban đầu
  • mBinding.indicator.setViewPager(mBinding.slideImageViewPager); -> truyền viewpager vào CircleIndicator để bắt sự kiện scroll viewpager
