我在我的應用程序中有Layout其中有5 Frame佈局。我在Graphical Layout中設計了它。它在佈局中顯示完美。但是當我在設備中運行應用程序時，它不顯示帶鍵盤的2個綠色按鈕symbol.It只在應用程序中顯示Red Area。佈局不顯示如圖形佈局所示？
我已經測試與另一Activity.It的佈局，它工作完美。我認爲有以下錯誤class。我無法找到它發生在哪裏？
沒有顯示在LogCat ......
所以幫我在正確的方向:)
感謝您的幫助......

可以肯定的是，圖形佈局中的設備和您的實際設備是相同還是具有相同特徵（屏幕尺寸和密度）？謝謝。 – fasteque
它們是一樣的...... – AruLNadhaN
'public PadActivity（）{super（）;}'你不需要這個。 –
