Pinyu

This app currently functions like a pocket dictionary. It contains a little over 50 Chinese words spanning different categories.

Pinyu is my first attempt to try and utilize less-naive design practices. I attempt to follow the MVP pattern here for my vocab review screens. I'm also utilizing inheritence and some static variables and methods to help with organization and navigation.

How it works

Pinyu gets its words from an SQLite database that contains the english word, pinyin, chinese character, category of a word, as well as corresponding sound and image resource IDs. The database can be found in assets/words.db.

The Content Provider (WordProvider.java) is defined in AndroidManifest.xml file. This Provider is accessed by the Content Loader in the Vocab Activity parent class. The Loader uses a URI to access the Provider and query different categories to display for each activity, depending on which category the user selected. This data is loaded into a custom adapter that defines the display formatting for the words and the sound play buttons.

Possible improvements

Improvements to this app would include using Fragments over Activities for the vocabulary review screens, as well as potentially using a Navigation Architecture Component to handle different fragment navigations.
