無法在GLSurfaceView上獲取android touch事件

Question

系統在我的應用程序中未調用onTouchEvent。 我已經嘗試在活動，視圖和呈現器中使用onTouchEvent實現它。他們都沒有被召喚。 所以我嘗試了dispatchTouchEvent活動和視圖，仍然沒有得到調用。 它基於San Angeles NDK樣本，我編譯並正確檢測觸摸。

以下是完整的java源代碼，其他一切都是原生C++。

Answer 1

onTouch作品無處不在，你想（即如果它的活性或視圖）只要你聲明的接口，並把監聽器吧！在另一方面的onTouchEvent一種觀點

換句話說內唯一的工作，onTouch（）用於通過查看的用戶獲得的觸摸事件而的onTouchEvent（）所使用的派生類查看獲得觸摸事件

嘗試，與onTouch取代的onTouchEvent ..

希望這有助於
