Glide使用

# Glide 加载本地图片

public static final String ANDROID_RESOURCE = "android.resource://";
public static final String FOREWARD_SLASH = "/";

private static Uri resourceIdToUri(Context context, int resourceId) {
    return Uri.parse(ANDROID_RESOURCE + context.getPackageName() + FOREWARD_SLASH + resourceId);
}

//这可能是任何 Uri。为了演示的目的我们只是用一个 launcher icon 去创建了一个 Uri 
Uri uri = resourceIdToUri(context, R.mipmap.future_studio_launcher);

Glide
    .with(context)
    .load(uri)
    .into(imageViewUri);

glide产生一个bitmap

private SimpleTarget target = new SimpleTarget<Bitmap>() {  
    @Override
    public void onResourceReady(Bitmap bitmap, GlideAnimation glideAnimation) {
        // do something with the bitmap
        // for demonstration purposes, let's just set it to an ImageView
        imageView1.setImageBitmap( bitmap );
    }
};

private void loadImageSimpleTarget() {  
    Glide
        .with( context ) // could be an issue!
        .load( eatFoodyImages[0] )
        .asBitmap()
        .into( target );
}

Glide 作用一个自定义的视图

public class FutureStudioView extends FrameLayout {  
    ImageView iv;
    TextView tv;

    public void initialize(Context context) {
        inflate( context, R.layout.custom_view_futurestudio, this );

        iv = (ImageView) findViewById( R.id.custom_view_image );
        tv = (TextView) findViewById( R.id.custom_view_text );
    }

    public FutureStudioView(Context context, AttributeSet attrs) {
        super( context, attrs );
        initialize( context );
    }

    public FutureStudioView(Context context, AttributeSet attrs, int defStyleAttr) {
        super( context, attrs, defStyleAttr );
        initialize( context );
    }

    public void setImage(Drawable drawable) {
        iv = (ImageView) findViewById( R.id.custom_view_image );

        iv.setImageDrawable( drawable );
    }
}


private void loadImageViewTarget() {  
    FutureStudioView customView = (FutureStudioView) findViewById( R.id.custom_view );

    viewTarget = new ViewTarget<FutureStudioView, GlideDrawable>( customView ) {
        @Override
        public void onResourceReady(GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {
            this.view.setImage( resource.getCurrent() );
        }
    };

    Glide
        .with( context.getApplicationContext() ) // safer!
        .load( eatFoodyImages[2] )
        .into( viewTarget );
}

Glide与自定义通知栏

    </LinearLayout>
</LinearLayout>  

final RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.remoteview_notification);

rv.setImageViewResource(R.id.remoteview_notification_icon, R.mipmap.future_studio_launcher);

rv.setTextViewText(R.id.remoteview_notification_headline, "Headline");  
rv.setTextViewText(R.id.remoteview_notification_short_message, "Short Message");

// build notification
NotificationCompat.Builder mBuilder =  
    new NotificationCompat.Builder(context)

    notification.bigContentView = rv;
}

NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);  
mNotificationManager.notify(NOTIFICATION_ID, notification);  

private NotificationTarget notificationTarget;

...

notificationTarget = new NotificationTarget(  
    context,
    rv,
    R.id.remoteview_notification_icon,
    notification,
    NOTIFICATION_ID);

Glide  
    .with( context.getApplicationContext() ) // safer!
    .load( eatFoodyImages[3] )
    .asBitmap()
    .into( notificationTarget );

Glide 动画

ViewPropertyAnimation.Animator animationObject = new ViewPropertyAnimation.Animator() {  
    @Override
    public void animate(View view) {
        // if it's a custom view class, cast it here
        // then find subviews and do the animations
        // here, we just use the entire view for the fade animation
        view.setAlpha( 0f );

        ObjectAnimator fadeAnim = ObjectAnimator.ofFloat( view, "alpha", 0f, 1f );
        fadeAnim.setDuration( 2500 );
        fadeAnim.start();
    }
};

Glide  
    .with( context )
    .load( eatFoodyImages[1] )
    .animate( animationObject )
    .into( imageView2 );

Glide改变动画质量

public class SimpleGlideModule implements GlideModule {  
    @Override public void applyOptions(Context context, GlideBuilder builder) {
        builder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);
    }

    @Override public void registerComponents(Context context, Glide glide) {
        // nothing to do here
    }
}


<manifest

            android:name="io.futurestud.tutorials.glide.glidemodule.SimpleGlideModule"

Glide 旋转90度

public class RotateTransformation extends BitmapTransformation {

    private float rotateRotationAngle = 0f;

    public RotateTransformation(Context context, float rotateRotationAngle) {
        super( context );

        this.rotateRotationAngle = rotateRotationAngle;
    }

    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        Matrix matrix = new Matrix();

        matrix.postRotate(rotateRotationAngle);

        return Bitmap.createBitmap(toTransform, 0, 0, toTransform.getWidth(), toTransform.getHeight(), matrix, true);
    }

    @Override
    public String getId() {
        return "rotate" + rotateRotationAngle;
    }
}


private void loadImageRotated() {  
    Glide
        .with( context )
        .load( eatFoodyImages[0] )
        .transform( new RotateTransformation( context, 90f ))
        .into( imageView3 );
}
