我正在尝试启动一个新活动的搜索按钮的OnClick
这个代码在几周前就可以正常工作了，突然之间
错误。
我该如何清除

注意：我已经在清单中声明了这两项活动
最佳答案
12-26 11:43:06.253: E/AndroidRuntime(506): java.lang.NoClassDefFoundError: com.project.findmybuffet.SearchPage

无法找到
com.project.findmybuffet.SearchPage类。请检查一次您的包裹名称。<activity android:name="com.project.findmybuffet.SearchPage" >
</activity>
您在此路径
"com.project.findmybuffet.SearchPage"中提到了搜索页活动，因此请检查SearchPage.class是否在该路径中。如果一切都很好。尝试清理您的项目，然后再次运行
现在试试这个
Photos.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent photoIntent=new Intent(AndroidTabRestaurantDescListView.this,AndroidTabRestaurantDescImageListView.class);
startActivity(photoIntent);
}
});
Filter.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent filterIntent=new Intent(AndroidTabRestaurantDescListView.this,Filters.class);
startActivity(filterIntent);
}
});
Search.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub

startActivity(searchIntent);
}
});
Account.setOnClickListener(new OnClickListener() {
