Image is not loaded using Glide

由 半腔热情 提交于 2019-12-06 10:50:13
I have a vector image. If I want to set the image to ImageView, the picture is not loaded. code: Glide.with(this).load(R.drawable.vector_image).into(imageView) However, when I use: imageView.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.vector_image)) and it is working. Any ideas? Glide doesn't support vector drawables yet. So implementing vector drawables you have to do yourself. For reference you can check below links for this issue reported by developers on github: link 1 link 2 You can use like this. Glide.with(this) .load("") .placeholder(R.drawable.vector_image) .into

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 5 years ago . I have a number of "contact" objects each with an imageURL String associated with them. All the ways I've seen of putting images into a ListView involve manually putting images into a "drawable" folder and calling resources. Manually entering the images in would defeat the purpose of this. I've

ImageView Android RAM

由 泪湿孤枕 提交于 2019-12-06 09:51:42
问题 A followup from my original question. Is there a way to use ImageViews in android apps without using a lot of RAM? In the original question I found that my app used a lot of RAM, and found that it was the ImageViews which I used that too up all the RAM. To get the Image I use public void addPictureOnClick(View view){ Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent, "Select Picture"),1); }

I want display images from HTML, and I get image url source using Jsoup . But, a problem is that each post has a different number of pictures. So, I can't fix the number of ImageViews in xml layout. After I researched, I know that I can create ImageViews dynamically. So, I create ImageViews and insert them into Linearlayout . But, I can only see one picture which I inserted lastly. package kr.ac.mju.hanmaeum.activity.notice; import android.content.Intent; import android.media.Image; import android.os.AsyncTask; import android.os.Bundle; import android.text.Html; import android.util.Log; import

由 こ雲淡風輕ζ 提交于 2019-12-06 07:30:16
I'm making an app that will allow the user to add a photo to an imageview from the gallery of their phone which I have already been able to code successfully.

Android ImageView topCrop/bottomCrop scaletype?

由 不羁岁月 提交于 2019-12-06 07:05:41
问题 I have a square ImageView which displays pictures of varying dimensions. I want to always maintain the original aspect ratio of the pictures and have no margin around the image (so that the image takes up the whole ImageView). For this, I am using the centerCrop scaleType on the ImageView . However, I want to make it so that if the top and bottom of the image are cut off (i.e.: the image is taller than it is wide), the image gets pulled towards the bottom of the container. So instead of
