我在实施时遇到错误。错误说"令牌上的语法错误" implements",@ expected" 。为什么我会收到此错误,我该如何解决此问题?
因为我是android的新手是什么做了关键字呢?

// The user selected the headline of an article from the HeadlinesFragment
// Do something here to display that article
NewsFramgment articleFrag = (NewsFramgment)
getSupportFragmentManager().findFragmentById(R.id.list);
if (articleFrag != null) {
System.out.print("no news found");
} else {
// Otherwise, we're in the one-pane layout and must swap frags...
// Create fragment and give it an argument for the selected article
NewsFramgment newFragment = new NewsFramgment();
Bundle args = new Bundle();
args.putInt(NewsFramgment.ARG_POSITION, position);
newFragment.setArguments(args);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack so the user can navigate back
transaction.replace(R.id.content_frame, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
}
}
答案 0 :(得分:1)
您遇到语法错误:
public class MainActivity extends SlidingFragmentActivity {
implements HeadlinesFragment.OnHeadlineSelectedListener{
应该是:
public class MainActivity extends SlidingFragmentActivity implements HeadlinesFragment.OnHeadlineSelectedListener{
下次查看catlog并查看导致问题的行号,这将缩小对语法错误的搜索范围。
