我想在我的Android应用程序中使用listview一旦项目点击列表就会转到下一个Activity.But在下一个Activity中我使用了cordova-2.0.0 jar文件来获取手机间隙;当我运行时应用它在itemClickListnere上获取NoClassdefFoundError。有人请帮助我。感谢。
这是我的代码。 public class Learn_Screen扩展了Activity { ListView chapter_ListView;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.learn);
chapter_ListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
String strChapter_Content = adapter.getItem(position);
System.out.println("strChapter_Content = " + strChapter_Content);
Intent i = new Intent(Learn_Screen.this , Chapter_Detail.class);
startActivity(i);
finish();
}
});
}
这是另一个活动代码。
public class Chapter_Detail extends DroidGap
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/chapter_one.html", 10000);
}
}
这是我的LogCat信息。

答案 0 :(得分：0)
尝试从CordovaActivity而不是DroidGap进行扩展。您确定已将库正确添加到项目中（如果您正在使用ADT，则添加到/ libs并在构建路径中检查Order and Export）。
答案 1 :(得分：0)
你得到这个错误 您没有直接将cordova.jar复制到libs目录，而是复制到libs / phonegap-phonegap-ce32a3f / lib / android / cordova.jar
所以请记住：始终将罐子复制到libs文件夹的根目录中！
也不要忘记在menifest文件中提及它。
