Android how to identify item in listview with checkbox

半城伤御伤魂 提交于 2019-11-27 02:03:00
I am really stuck here. What I want is not simple (for me), however I've been programming android a year now. What I want is a listview with an imageview, a textview, a checkbox, and another textview in each row. Let's have a textview and a checkbox first in the layout. Based on this tutorial I managed to do that (there are a lot, but this seems to be the best for me). I have a listview populated with textviews and checkboxes. This is the result: This is how I get the text of textview I click on: textView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {

Loading remote images

In Android, what is the simplest approach to the following: Load an image from a remote server. Display it in an ImageView. Felix Here's a method that I actually used in an application and I know it works: try { URL thumb_u = new URL("http://www.example.com/image.jpg"); Drawable thumb_d = Drawable.createFromStream(thumb_u.openStream(), "src"); myImageView.setImageDrawable(thumb_d); } catch (Exception e) { // handle it } I have no idea what the second parameter to Drawable.createFromStream is, but passing "src" seems to work. If anyone knows, please shed some light, as the docs don't really say

How to insert drawables in text

问题 I want to insert small pictures, like arrow icons for example, into certain positions of contents of a TextView . The photo below depicts exactly what I want: Obviously, the most naive solution is to use multiple TextView on either side of the small ImageView objects. But this approach is not scalable. I am curious to learn if someone has overcome this problem with some simple yet smart trick. (Maybe with help from HTML or an external library) Any efficient solution is much appreciated. 回答1:

Load Large Image from server on Android

问题 I am trying to display a jpg file from a server into an imageView. When I try to load a smaller image (300x400), there are no problems. But when I try to load a full size picture (2336x3504), the image will not load. The file size of the image is only 2mb. I do not get any errors in logcat and there are no exceptions thrown. It simply won't load the image. I also tried using this: BitmapFactory.Options options=new BitmapFactory.Options(); options.inSampleSize = 8; Bitmap preview_bitmap
