Inoreader is free with no in-app purchases or advertisements. There is also a premium plan that adds some extra features, such as no ads, support for social media profiles, and more.
Microsoft News is actually a decent news aggregator. It works a lot like Feedly, Flipboard, and similar apps. You open the app, define your topics, and get a news feed. Your settings are synced to the web version as well although syncing is a bit finicky from time to time.
Some other features include the ability to save articles for later, a good selection of news websites, and a clean UI. Palabre is one of the more traditional RSS reader apps. It also works with a variety of other RSS mobile apps. The app features a simple, Material Design interface, several customization options, and more. It still needs a bit of work. However, it works well most of the time. You can get the app for free. There is also a pro version that adds some additional features, such as a dark theme.
Podcast Addict takes the opposite approach. It is primarily a podcast app. However, it also supports an RSS feed as well. This is great for people who listen to a bunch of podcasts but also want something to read every now and then.
The app comes with a ton of features for both RSS and podcasts, including widgets, Android Wear support, Android Auto support, and more. The pro version removes ads and gives you some extra features. Twitter is a semi-decent okay place for news as long as you follow the right sources. Believe it or not, you can actually treat this very much like an RSS reader. An RSS document looks like this. It could be a file or could be a Stream. In our case it is a stream.
The last step is to parse the XML. The method getEventType returns the type of event that happens. The method getName returns the name of the tag and since we are only interested in temperature, so we just check in conditional statement that if we got a temperature tag, we call the method getAttributeValue to return us the value of temperature tag. In next post, I will load the data from real Rss feed instead of run time rendering. As the above figure, I will customize the ListView with more Android components.
Then, I will add two TextView align with the image component. For the top text, I will style the text with big font and 2 lines. For the bottom text, I will make the font smaller than the top one. Here is our customized ListView source code example.
For complicated data and list cell view, we need to implement a new adapter class which inherit from ArrayAdapter and override the function getView to get the list cell view.
Here is the example code. Now, I will talk about the performance of Android ListView. In above example, I generate 10 list entities. However, the app will get slower and slower when there are more data in the data list. In the adapter class, we inflate a new View object for each coming data entity.
This approach is very expensive. To make this android ListView fast and efficient, we can improve the Adapter class and reuse some cell view. There are two ways to make it fast. Using the recycling view will be more efficient than instantiating a new view each time. Usually, the android ListView performance will be increased by 2 times. Here is the improved getView function in adapter class.
After we use the recycling views in the ListView, the performance of the new app has a clear improvement. However, there is more space for use to improve. We can avoid it by using ViewHolder. Hence, we can get the objects in cell view directly by reference directly, instead of calling findViewById. Here is the third variation of getView function. In this tutorial guide, I just demonstrate how to customize ListView with images and text. But in the example, I am only using a static image to make it easy to understand.
For different project, the requirement may not be the same. Some application may request to add more Android components in the ListView, for example, a button which can handle users clicking. For this more complicated customization, I recommend you to read following articles. It is quite a complete guide for you to get where the users click.
The example performs quite great. However, we are still using fake data to generate the tables. Go to next tutorial: Loading data from internet in Android. Thank you. GetView is a function in PostItemAdapter.
