Getting started with glide4

Directory:

I. Introduction

Same as other image loading libraries, Glide can load local images in addition to network images.You can even load images from all sorts of weird data sources.This article will introduce how to use Glide4 to load network pictures, local pictures, and pictures in resource files.

Second, load network pictures

 This has been mentioned before, just put a piece of code, so I won't explain much.

ImageView imageView = findViewById(R.id.image_view);
String url = “https://www.niwoxuexi.com/statics/images/nougat_bg.png”;
Glide.with(context)
.load(url)
.into(imageView);
3. Load local image

glide is also very simple to record local images, and it is also implemented through .load() . Let's take a look at .load() to load various resources

Note: The permission to read the SD card should be added to the AndroidManifest.xml for loading the SD card image

如果是运行在Android 6.0 以上的手机上，还要在代码中动态的申请读取SD卡的权限（我这里就不多讲了，大家可以自行从网上查找)

1, load the SD card resource image

// Load the test.jpg image in the root directory of the SD card
String path = “file://” + Environment.getExternalStorageDirectory().getPath()+“/test.jpg”;
Glide.with(context)
.load(path)
.into(imageView);

ImageView imageView = findViewById(R.id.image_view);
// Load the root directory of SD cardtest.jpg image, read through Flie file
File file = new File(Environment.getExternalStorageDirectory(), “test.jpg”);
Glide.with(context)
.load(file)
.into(imageView);
2, load the drawable resource image

Method: load(R.drawable.image_test)

ImageView imageView = findViewById(R.id.image_view);
// Load the image image_test.png under the resource file drawable
Glide.with(this)
.load(R.drawable.iamge_test)
.into(imageView);
3. Load assets resource file

Method: load("file:///android_asset/image_test.png")

ImageView imageView = findViewById(R.id.image_view);
// Load the resource file under assetsImage image_test.png
String path = “file:///android_asset/image_test.png”;
Glide.with(this)
.load(path)
.into(imageView);
4. Load raw resource image

Method: load("android.resource://package name/raw/raw_1") or load("android.resource://package name/raw/"+R.raw.raw_1)

I'm not going to code this, let's draw a scoop of rice gourd

5, of course, load is not limited to the above types, and the following parameters can also be loaded. I will not give an example. Anyone who is interested can learn from Baidu by themselves

Parameter description
.load(String string) string can be a file path, uri or url
.load(Uri uri) uri type
.load(File file) file
.load(Integer resourceId) Resource Id, R.drawable.xxx or R.mipmap.xxx
.load(byte[] model) byte[] type
.load(T model) custom type
