Android Glide加载网络的svg图片
·
- 添加依赖
implementation ‘com.github.bumptech.glide:glide:4.11.0’
annotationProcessor ‘com.github.bumptech.glide:compiler:4.11.0’
implementation ‘com.caverock:androidsvg:1.2.1’
- 新建SvgDecoder.java
public class SvgDecoder implements ResourceDecoder<InputStream, SVG> {
@Override
public boolean handles(@NonNull InputStream source, @NonNull Options options) {
// TODO: Can we tell?
return true;
}
public Resource<SVG> decode(
@NonNull InputStream source, int width, int height, @NonNull Options options)
throws IOException {
try {
SVG svg = SVG.getFromInputStream(source);
if (width != SIZE_ORIGINAL) {
svg.setDocumentWidth(width);
}
if (height != SIZE_ORIGINAL) {
svg.setDocumentHeight(height);
}
return new SimpleResource<>(svg);
} catch (SVGParseException ex) {
throw new IOException("Cannot load SVG from stream", ex);
}
}
}
- 新建SvgDrawableTranscoder.java
public class SvgDrawableTranscoder implements ResourceTranscoder<SVG, PictureDrawable> {
@Nullable
@Override
public Resource<PictureDrawable> transcode(
@NonNull Resource<SVG> toTranscode, @NonNull Options options) {
SVG svg = toTranscode.get();
Picture picture = svg.renderToPicture();
PictureDrawable drawable = new PictureDrawable(picture);
return new SimpleResource<>(drawable);
}
}
- 新建SvgModule.java
@GlideModule
public class SvgModule extends AppGlideModule {
@Override
public void registerComponents(
@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
registry
.register(SVG.class, PictureDrawable.class, new SvgDrawableTranscoder())
.append(InputStream.class, SVG.class, new SvgDecoder());
}
// Disable manifest parsing to avoid adding similar modules twice.
@Override
public boolean isManifestParsingEnabled() {
return false;
}
}
- 新建SvgSoftwareLayerSetter.java
public class SvgSoftwareLayerSetter implements RequestListener<PictureDrawable> {
@Override
public boolean onLoadFailed(
GlideException e, Object model, Target<PictureDrawable> target, boolean isFirstResource) {
ImageView view = ((ImageViewTarget<?>) target).getView();
view.setLayerType(ImageView.LAYER_TYPE_NONE, null);
return false;
}
@Override
public boolean onResourceReady(
PictureDrawable resource,
Object model,
Target<PictureDrawable> target,
DataSource dataSource,
boolean isFirstResource) {
ImageView view = ((ImageViewTarget<?>) target).getView();
view.setLayerType(ImageView.LAYER_TYPE_SOFTWARE, null);
return false;
}
}
- activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

<androidx.appcompat.widget.AppCompatImageView
android:id="@+id/imageView"
android:layout_width="56dp"
android:layout_height="56dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
- MainActivity.class
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView imageView = findViewById(R.id.imageView);
Glide.with(this).as(PictureDrawable.class)
.listener(new SvgSoftwareLayerSetter())
.load("http://192.168.101.58:8080/demo/demo.svg").into(imageView);
}
}
Android 9.0 http网络请求需要在AndroidManifest.xml中添加networkSecurityConfig
<application
android:networkSecurityConfig="@xml/network_security_config">
</application>
在res目录下新建xml/network_security_config.xml文件
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
