I found ListView control in Android is very easy to use, that is very good. Even there is a method to set the empty view, it will display it when the list context is empty.
You put any view in there. I put a LinearView with a Textview. That is easy!
If you wish to do some actions, such as auto save, when the user go to other app, therefore the user put your app in a sleep mode at the background
You must override the onPause() method like below:
At first, I upgrade my android studio to 1.3 preview from 0.8.6. I have not upgrade for ages, that is good to have the newest version. I have used their beta version for a while, android studio doesn't sound too bad even the version is still in beta. Thus, I used 1.3 preview rather than 1.2 stable. However, I spent some hours to upgrade my existing projects to work with this version of android studio. But I found their Gradle which has some problems to get google play ads library. Even I installed Google Support repository and Google Play library. Gradle still cannot find the ads library.
Finally, I gave up. I went back to Android Studio 1.2, then that is good all!
Android Studio Error :appcompat-v7:21.0.0': No resource found that matches the given name: attr "adnroid;XXXX"
After I upgraded my android studio from 0.86 and 1.2. I tried to build my project, I got a lot of errors like appcompat-v7:21.0.0': No resource found that matches the given name: attr: android :xxxx"
Actually, that is because appcompat-v7:21.0.0' required API 21. So, I need to install API 21 Platform SDK, Extra> Google Support Repository and Google Support Library.
The most important part, the part I missed, in the build.gradle set complie sdk to 21
To display object value in MultiAutoCompleteTextView, you have to build a custom adapter:
For example, I have a tag class, which has Id field and name field.
Firstly, you need to have an adapter
Then you need to change in CreateView at the fragment class
multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); List
tagList = app.GetTags(); TagAdapter tagAdapter= new TagAdapter((Context)getActivity(),tagList); multiAutoCompleteTextView.setThreshold(1); multiAutoCompleteTextView.setAdapter(tagAdapter);
