android - R.java不可修改

Question

我试图修改 android 中的 R.java。我删除了生成的 java 文件。保存之后好像没有什么变化。我的 R.java 文件看起来像这样

/* AUTO-GENERATED FILE.  DO NOT MODIFY. 
 *
 * This class was automatically generated by the
 * aapt tool from the resource data it found.  It
 * should not be modified by hand.
 */
public final class R {
public static final class attr {
}
public static final class drawable {
    public static final int icon=0x7f020000;
}
public static final class id {
    public static final int myEditText=0x7f050000;
    public static final int myListView=0x7f050001;
}
public static final class layout {
    public static final int colors=0x7f030000;
    public static final int dimens=0x7f030001;
    public static final int main=0x7f030002;
}
public static final class string {
    public static final int app_name=0x7f040001;
    public static final int hello=0x7f040000;
}
}

我想改变它，让它更像这个:

 /* AUTO-GENERATED FILE.  DO NOT MODIFY.    
 *
 * This class was automatically generated by the
 * aapt tool from the resource data it found.  It
 * should not be modified by hand.
 */
public final class R {
public static final class attr {
}

public static final class color {
    public static final int notepad_lines=0x7f040001;
    public static final int notepad_margin=0x7f040002;
    public static final int notepad_paper=0x7f040000;
    public static final int notepad_text=0x7f040003;
}
public static final class drawable {
    public static final int icon=0x7f020000;
}
public static final class id {
    public static final int myEditText=0x7f050000;
    public static final int myListView=0x7f050001;
}
public static final class layout {
    public static final int colors=0x7f030000;
    public static final int dimens=0x7f030001;
    public static final int main=0x7f030002;
}
public static final class string {
    public static final int app_name=0x7f040001;
    public static final int hello=0x7f040000;
}
}

每次保存时都非常令人沮丧，因为它是自动生成的，所以它会恢复到原来的状态。我该如何修改它？

Answer 1

R.java 是一个自动生成的文件，包含您在项目中使用的所有资源。如果你想改变 R.java 你不能。

您必须添加或删除资源，然后它会根据您在项目中存在的资源进行修改。

这是 Android 中的基本内容。你必须阅读 Android 开发者文档，然后你才会对它有很好的了解。
