Android图片加载框架Coil，Kotlin

implementation("io.coil-kt:coil:1.4.0")

import android.os.Bundle
import android.widget.ImageView
import androidx.appcompat.app.AppCompatActivity
import androidx.lifecycle.lifecycleScope
import coil.Coil
import coil.ImageLoader
import coil.request.ImageRequest
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launchclass MainActivity : AppCompatActivity() {companion object {val SIZE = 400}override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.image_layout)val imageView = findViewById<ImageView>(R.id.image)val ctx = this.applicationContextval mImageLoader = ImageLoader.Builder(ctx).build()Coil.setImageLoader(mImageLoader)val request = ImageRequest.Builder(ctx).size(SIZE).data(R.mipmap.p).target(imageView).build()lifecycleScope.launch(Dispatchers.IO) {Coil.execute(request)}}
}

或者：

import android.graphics.drawable.Drawable
import android.os.Bundle
import android.util.Log
import android.widget.ImageView
import androidx.appcompat.app.AppCompatActivity
import androidx.lifecycle.lifecycleScope
import coil.Coil
import coil.ImageLoader
import coil.request.ImageRequest
import coil.target.Target
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launchclass MainActivity : AppCompatActivity() {companion object {val SIZE = 400}override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.image_layout)val imageView = findViewById<ImageView>(R.id.image)val ctx = this.applicationContextval mImageLoader = ImageLoader.Builder(ctx).build()Coil.setImageLoader(mImageLoader)val request = ImageRequest.Builder(ctx).size(SIZE).data(R.mipmap.p).target(object : Target {override fun onStart(placeholder: Drawable?) {super.onStart(placeholder)Log.d("fly", "onStart")}override fun onSuccess(result: Drawable) {super.onSuccess(result)Log.d("fly", "onSuccess")imageView.setImageDrawable(result)}}).build()lifecycleScope.launch(Dispatchers.IO) {Coil.execute(request)}}
}

Coil是专门针对Android平台上的Kotlin语言特性设计，这不像Glide，Glide的核心框架语言是Java。Coil实现看更细颗粒度的内存、磁盘缓存的客制化设置。
