Android 第一行代码

日志文件如下：

相关代码：

public class NewsTitleFragment extends Fragment implements AdapterView.OnItemClickListener {

.....

@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position, long id) {    News news = (News) newsArrayList.get(position);    if (isTwoPageModel){        Log.v("NewsTitleFragment","Sorry, pad screen adapter not complete");    }else {        NewsContentActivity .actionStart(getActivity(), news.getTitle(), news.getContent());    }}.....}

public class NewsContentActivity extends AppCompatActivity {    public  static  void actionStart(Context context, String title, String content){        Intent intent = new Intent(context,NewsContentActivity.class);        intent.putExtra("title", title);        intent.putExtra("content", content);        context.startActivity(intent);        Log.v("NewsContentActivity", "startActivity");    }
....
}

最终执行时，程序没有执行NewsContentActivity的onCreate方法。

在重写onCreate方法时选择了

import android.app.Activity;

包中的

@Overridepublic void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {    super.onCreate(savedInstanceState, persistentState);}

方法，导致了日志中的：

Could not find method android.support.v7.app.AppCompatActivity.onCreate
情况。
