Glide缓存图片

是用Glide加载网络图片可以自动缓存到磁盘

添加依赖:

    implementation  'com.github.bumptech.glide:glide:4.9.0'
    implementation 'com.android.support:support-v4:28.0.0'

public class MainActivity extends AppCompatActivity {
    CompositeDisposable disposables;
    @SuppressLint("CheckResult")
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ImageView imageView = (ImageView) findViewById(R.id.image);
        String url = "https://ss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=1036218379,1213399244&fm=27&gp=0.jpg";
        Glide.with(this)
                .load(url)
                .into(imageView);
            }
        }
