當我運行我的應用程序工作正常，但是當我點擊按鈕停止，並保持回採這裏是我的代碼，設置活動：Android的錯誤，無法對Android的執行方法：的onClick

請將Logcat的完整錯誤輸出添加到您的文章中。 –

好吧我編輯了我的問題，添加了錯誤 –

這是你需要看的一行：'由於：android.database.sqlite.SQLiteException：near「all」：語法錯誤（代碼1）：，編譯時：create table如果不存在模式（ID INTEGER主鍵，名稱TEXT，當前INTEGER，所有INTEGER）''但是，似乎你發佈的代碼並沒有我們需要的所有必要的細節來調試它 –

的問題是從您的SQL查詢進來DBConnections

create table IF NOT EXISTS Patterns (ID INTEGER primary key,name TEXT,current INTEGER,all INTEGER)

all是一個reserved word in SQLite，所以我強烈建議您使用不同的名稱爲您的專欄，以避免將來的混淆。

你也可以用如下引號將其轉義：「all」

非常感謝你，安德魯 –

這是一個與你的SQL語句創建一個錯誤。 all是SQL中的關鍵字，因此您不能將其用作這樣的字段名稱。或者使用一些不同的字段名稱或周圍的名稱添加引號，以避免錯誤
