Glide加载网络图片的简单使用(参考老罗代码)

1.库的引入:

dependencies {
    compile 'com.github.bumptech.glide:glide:3.5.2'
    compile 'com.android.support:support-v4:22.0.0'
}

2.Glide加载网络图片需要添加网络权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

3.基本方法使用

      Glide.with(this)

        //加载网址

        .load(picUrl)
        //设置占位图
        .placeholder(R.mipmap.ic_launcher)
        //加载错误图
        .error(R.mipmap.ic_launcher)
        //磁盘缓存的处理
        .diskCacheStrategy(DiskCacheStrategy.ALL)
        .into(ivShow);

4.加载Gif图片

Glide.with(MainActivity.this)
        .load(picGifUrl)
        .asGif()
        .diskCacheStrategy(DiskCacheStrategy.SOURCE)
        .into(ivShow);

5.实例代码

  xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
>

    <ImageView
        android:id="@+id/iv_img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <Button
        android:id="@+id/btn_loadImage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Glide加载图片" />
    <Button
        android:id="@+id/btn_loadImageGif"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Glide加载Gif图片" />

</LinearLayout>
