Android图片全屏查看器

Question

我是android的新手。点击图像时，像whatsapp图像一样，将图像视图弹出到全屏（启用捏合缩放）的最简单方法是什么？我正在通过Glide在回收器视图中加载图像。感谢您的时间和答复。

Answer 1

I used PhotoView (https://github.com/chrisbanes/PhotoView) and Glide (https://github.com/bumptech/glide).

I created full screen activity first and put PhotoView in layout.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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"
    android:background="#000000"
    tools:context=".PhotoviewerActivity">

    <com.github.chrisbanes.photoview.PhotoView
        android:id="@+id/fullscreen_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</FrameLayout>

Then, I pass image URL that I want to show to the full screen activity and load image with Glide like below.

val imageUrl = intent.getStringExtra(IMAGE_URL)
Glide.with(applicationContext).load(imageUrl).into(fullscreen_content)

You can remove all not needed code from full screen layout and also disable from full screen activity code. These codes are written in Kotlin.

有一个名为StfalconImageViewer的库。它支持开箱即用的过渡动画，用于图像的打开和关闭，捏合缩放和滑动消除手势。使用Glide可以像这样完成：

new StfalconImageViewer.Builder<>(context, images, new ImageLoader<String>() {
            @Override
            public void loadImage(ImageView imageView, String imageUrl) {
                Glide.with(context).load(imageUrl).into(imageView)
            }
        }).show();

希望这可以帮助！
