我正在设计一个以RelativeLayout为根的布局，后面跟着'n'个子和一个LinearLayout。在LinearLayout内部我有一个TextView，它会导致一个力关闭。请查看我的代码并帮助我：

布局中的此ID android:id="@+id/txt_lbl_add_bill_and_expense_amount_spent"会导致强制关闭
所以我的类文件是引用

mTvAddBillAndExpenseTitle = (TextView) findViewById(R.id.txt_lbl_add_bill_and_expense_title);

答案 0 :(得分：0)
我认为您的类文件中对此ID的引用是 除TextView之外的其他内容，或者清理项目。请检查代码中的ID引用。
