所以我刚刚开始学习Android应用程序开发，当我在玩UI时，一切都很好，但当我开始添加一些Java代码时，每当我运行程序时，它都会运行，但当我点击一个按钮时，它会说

不幸的是，程序名已停止

我的.xml看起来像

<TextView
    android:id="@+id/display"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="35dp"
    android:text="Your total is: 0"
    android:textSize="45dp" />

<Button
    android:id="@+id/subtract"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/add"
    android:layout_alignRight="@+id/add"
    android:layout_centerVertical="true"
    android:text="Subtract One" />

<Button
    android:id="@+id/add"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:layout_above="@+id/subtract"
    android:layout_centerHorizontal="true"
    android:gravity="center"
    android:text="Add One" />

我的错误看起来像这样

问题出在这一行：

display.setText(total);

您正在传递一个整数（总计），系统将其解释为资源id。请尝试以下操作：

display.setText(Integer.toString(total));

代码中的变量total的类型为int。当传递给setText时，Android将此int视为不存在的资源ID，并使程序崩溃。您需要将int转换为字符串（或者具体地说，转换为实现CharSequence的类型）

请参阅TextView文档：

替换

display.setText（总计）
按display.setText（总计+”）
这行代码有用吗：android.content.res.Resources$NotFoundException:String resource ID#0x11-29 20:11:37.645:E/AndroidRuntime（1000）：at-android.content.res.Resources.getText（Resources.java:244）？
display.setText(Integer.toString(total));
