我有一個增強現實應用程序,顯示相機視圖和GLSurfaceView與可以旋轉觸摸屏幕的多邊形。我的應用程序的主要佈局是一個FrameLayout。 frameLayout包含cameraView和GLSurfaceView。我的應用在屏幕上還有兩個按鈕(放大/縮小),覆蓋cameraView的RelativeLayout。我的相機視圖重疊GLSurfaceView ...但我想它被覆蓋GLSurfaceView
問題是cameraview與其他兩個視圖(縮放按鈕和GLSurfaceView與多邊形)重疊,我只能看到屏幕上的cameraView。如果我從我的應用程序的主FrameLayout刪除cameraview,然後我可以看到GLSurfaceView和縮放按鈕沒有問題。
我該如何解決這個問題?我需要的是GLSurfaceView覆蓋的cameraView和RelativeLayout的變焦按鈕覆蓋的GLSurfaceView ...
有些更新:
我檢查,在安卓2.2.2(摩托羅拉Droid)它的作品完美,但如果我測試它的版本從1.5到2.1,然後它壞了,cameraview overlapps其他視圖...
我還檢查了,如果我顛倒對我的應用程序的內容查看意見位置(首先是GLSurfaceView,在相機之後,最後是按鈕),然後在Android 1.5到2.1上工作...但是不適用於android 2。 2.2和更高版本!我要瘋了這... ...
這是代碼:
