スライドパズルでViewとSurfaceViewとOpenGL(GLSurfaceView)を比較 その2
今日はViewを使ったソースコード。次回OpenGL版のソースコード、次々回とその次で、解説とeclipseにそのままインポートして使えるプロジェクトをアップします。
写真は、このソースでの表示画面。2ブロックを指で左へスライドさせている時のキャプチャです。
SlidePuzzle.javaは前回と変わりませんが、前回のSurfaceViewからViewに切り替えるフラグとして、view_flgを真に変更します。
view_flg = false → true; surfaceview_flg = true → false; glsurfaceview_flg = false → false;
