我的應用程序突然停止

我的應用程序突然停止了。我添加了一個tabhost，並在其中添加了一個對話框。因此，當我運行我的應用程序時，它突然停止，同時重定向到我所擁有的活動創建了我的標籤主機。我的logcat出現錯誤，有誰能幫我找到解決方案嗎？我的應用程序突然停止

我已張貼上面請吧.. – user2656455

哪條線是Friends.java:57？ – m0skit0

不要使用'getBaseContext'或'getApplicationContext（）'來創建對話框。使用'this'或'ActivityName.this'。 –

好像你叫你的名字Activity錯在定義Intent。

行：

Intent FriendsIntent = new Intent(this,Friends_list.class);

應該

Intent FriendsIntent = new Intent(this,Friends.class);

試着改變生成器的構造函數：

新AlertDialog.Builder（本）;

改變你在上下文ActivityName.this或getApplicationContext（）你

AlertDialog.Builder alertDialogBuilder=new AlertDialog.Builder(getBaseContext());
