android: 用glide加载网络图片

一，安装第三方库glide

1,库地址:

https://mvnrepository.com/artifact/com.github.bumptech.glide/glide

2,安装:
编辑build.gradle,在dependencies段增加如下一行

    // https://mvnrepository.com/artifact/com.github.bumptech.glide/glide
    implementation 'com.github.bumptech.glide:glide:4.16.0'

然后点击Sync Now

二，代码：

xml:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FF6600"
    android:layout_gravity="center"
    tools:context=".activity.ImageActivity">

    <ImageView
        android:id="@+id/userImage"
        android:layout_width="700px"
        android:layout_height="700px"
        android:background="#000000"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
         />

</androidx.constraintlayout.widget.ConstraintLayout>

java:

package com.example.okdemo1.activity;

import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.Window;
import android.widget.ImageView;

import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;

import com.bumptech.glide.Glide;
import com.bumptech.glide.load.engine.DiskCacheStrategy;
import com.bumptech.glide.request.RequestOptions;
import com.example.okdemo1.R;

public class ImageActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);

        // 设置activity的窗口属性为contentFeature,即可使用切换动画
        getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS);
        Transition explode = TransitionInflater.from(this).inflateTransition(R.transition.slide_right);
        // 此处获取了系统内置的explode动画效果设置给了activity的窗口对象
        getWindow().setEnterTransition(explode);

        setContentView(R.layout.activity_image);

        //String imageUrl = "https://wx2.sinaimg.cn/mw690/0034c2ttly1i0s6zuaqrkj635s2n4npe02.jpg";
        String imageUrl = "https://wx4.sinaimg.cn/mw690/0034c2ttly1i0s6zu16kuj62bc3cge8102.jpg";
        ImageView imageView = findViewById(R.id.userImage);
        Glide.with(this)
                .load(imageUrl)
                //.apply(RequestOptions.circleCropTransform()) // 使用 circleCropTransform() 方法设置圆形图片，也可以使用圆角半径的方法设置圆角
                .diskCacheStrategy(DiskCacheStrategy.ALL) // 缓存原始图片和转换后的图片到磁盘
                .skipMemoryCache(false) // 不跳过内存缓存
                .into(imageView);
    }
}
