在我的一个课程中,我收到此错误:游戏无法解析或不是字段,当我启动应用程序时它说无法打开请再试一次,为什么我一直收到此错误,是否有错误与R.java?
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,都会自动编译R.java,但如果某个xml文件中存在错误,则不会更新。
仔细检查所有XML文件是否有错误(Lint应自动为您标记错误)。此外,请检查您必须确保它们有效的任何9个补丁。您可以暂时从名称中删除.9
,以查看问题是否与9补丁格式有关。我遇到过9个补丁中的一些边界像素不是纯黑色或纯白色的情况,这导致R.java无法更新。

如果您发布了整个R文件,似乎您还没有定义游戏菜单,唯一找到的菜单是main:
public static final class menu {
public static final int main=0x7f080000;
}
如果您正确定义了菜单项,则需要使用R.menu.main,或者在res / menu中创建一个game.xml菜单文件。
