android启动activity报android.content.res.Resources$NotFoundException: String resource ID #x12

目标是做一个侧滑菜单，源代码如下

package com.app.news;import com.app.fragment.MenuFragment;import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity;import android.os.Bundle;import android.support.v4.app.Fragment;import android.view.Menu;import android.view.Window;public class MainActivity extends SlidingFragmentActivity {/* * 1.得到滑动菜单2.设置滑动菜单是在左边出来还是右边出来3.设置滑动此案的出来之后，内容页显示的剩余宽度4.设置滑动菜单的阴影 设置阴影宽度，阴影需要在开始的时候特别暗，慢慢的变淡5.设置阴影的宽度以及滑动菜单的范围 */    @Overridepublic void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        setBehindContentView(R.layout.menu);     //  setContentView(R.layout.activity_main);        setContentView(R.layout.content);   //     setContentView(R.id.content_frame); //使用帧布局动态替换内容                SlidingMenu sMenu=getSlidingMenu();        sMenu.setMode(SlidingMenu.LEFT);        sMenu.setBehindWidthRes(R.dimen.slidingmenu_offset);        sMenu.setShadowDrawable(R.drawable.shadow); //设置阴影        sMenu.setShadowWidth(R.dimen.shadow_width);        sMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); //设置全屏滑动              //创建fragment        MenuFragment menuFragment=new MenuFragment();         getSupportFragmentManager(). //获取fragment的管理者        beginTransaction().          //开启事务        replace(R.id.menu_frame, menuFragment,"Menu"). //替换android默认的frame        commit(); //提交事务                 }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }        /*     * 方法D     * 回调     */    public void switchFragment(Fragment f){    //点击哪个item就替换之前的content_frame(一片空白区域)    getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, f).commit();        }    }

然后项目运行起来，报了一下错误：

最后发现，是setContentView(R.id.content_frame);//使用帧布局动态替换内容 

出了问题，应该是

setContentView(R.layout.content);
