独自のContentProviderの作成
public class LauncherLiveFolderProvider extends ContentProvider
//自分でクラスを作成し、ContentProviderから継承するには、デフォルトでこれらの実装方法があります.
//データを読み取るだけなら、queryやgettypeなどを実現するのが基本です.
//
最近書いたsmsとbookmarkをlivefolderのコードに変えて、ahomeとcontactsのソースコードを参考にして作ったのです
provider定義の比較的勝手で、少し醜いようです.の
ソースコードはあまり読んでいませんが、smsの部分は完全に自分でデータベースの表の項目を見てから勝手に間に合いました.
1.LauncherLiveFolderAdapterURI.java. すべて変数です.
2.LauncherLiveFolderAdapter.JAvaはlivefolderオプションmenuでアプリケーションを満たすためのやつです
3 . LauncherLiveFolderProvider.JAva、読めばいいので、簡単です.
