Android：如何删除R.Java中的旧引用？

Question

我是Android的新手，对Android并不了解。好吧，我创建了一个名为button-layout.xml的布局，首先，我添加了一个相对布局，并将其命名为“按钮”。

发生的事情是它创建了r.java并将其列入我的布局用名称 公共静态最终int button-layout = 0x7f060000; 正如你们所知道的那样，您无法使用 - 在您的变量名称中，因为它是非法的。

现在我想清洁我的r.java，任何身体是否知道解决这个问题的解决方案？

在下面粘贴我的代码button-layout.xml

    <?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/button-layout">
    <LinearLayout android:id="@+id/button-layout"
        android:layout_height="wrap_content" android:layout_width="fill_parent">
        <TextView android:id="@+id/TextView01"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="First Name"></TextView>
        <EditText android:id="@+id/EditText01"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:width="100px"></EditText>
    </LinearLayout>
    <LinearLayout android:id="@+id/LinearLayout02"
        android:layout_below="@id/LinearLayout01" android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <TextView android:id="@+id/TextView02"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Last Name"></TextView>
        <EditText android:id="@+id/EditText02"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:width="100px"></EditText>
    </LinearLayout>
    <LinearLayout android:id="@+id/LinearLayout03"
        android:layout_below="@id/LinearLayout02" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_centerInParent="true">
        <Button android:id="@+id/Button01"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Submit"></Button>
    </LinearLayout>
</RelativeLayout>

Answer 1

R.Java文件由资源编译器（AAPT）自动生成。因此，每次更改项目并保存时，R.Java文件都会重建。

Answer 2

R.Java在构建项目时再次重建，Incase不会删除并重新构建。
