Java 为什么我总是遇到这个错误（无法解决）？

在我的一个类中，我遇到了这样一个错误：游戏无法解决或不是一个字段，当我启动应用程序时，它会说无法打开，请重试，为什么我一直遇到这个错误，R.java是否有问题

public class GameActivity extends Activity {

Grid myView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myView = new Grid(this);
    myView.setGame(new Game());
    setContentView(myView);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.game, menu);//error occurring here
    return true;
}}

每次修改

res

目录中的资源时，R.java都会自动编译，但如果其中一个xml文件中存在错误，则不会更新R.java

---

仔细检查所有XML文件是否有错误（Lint应该自动为您标记错误）。此外，请检查任何9个补丁，以确保它们是有效的。您可以暂时从名称中删除

.9

，以查看问题是否与9修补程序格式有关。我曾经遇到过这样的情况：我的9补丁中的一些边界像素不是纯黑色或纯白色，这导致R.java无法更新。

如果你发布了整个R文件，似乎你还没有定义游戏菜单，找到的唯一菜单是main：

public static final class menu {
    public static final int main=0x7f080000;
}

---

如果在其中正确定义了菜单项，则需要使用R.menu.main，或者在res/menu中创建一个game.xml菜单文件。

正如您所见，R.javagetMenuInflater（）中没有类似的资源“game”？getMenuInflater（）.充气（R.menu.main，menu）？请提供menu.xml src@Stan，getMenuInflater（）。充气（R.menu，menu）？否，他将以“R.menu无法解析为变量”结束。user3267882，查看我的答案，创建一个game.xml或使用res/menu中的main.xml…@2Dee仅在第一种情况下使用。@斯坦，这就是我说的，我们的评论编辑交叉激发；）您在res/menu文件夹中创建了game.xml？这应该可以做到，但你可能需要清理/重建你的项目…然后检查Tenfour04的答案，你可能在你的res文件夹（xml文件，9patch图像）的某个地方有一个错误，阻止你的R.java被更新。。。
