我有一个管理片段的类..在 TextView 我必须放置电话功能,但是因为错误?
import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class PageFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = getActivity().getLayoutInflater().inflate(R.layout.fragment_page, null);
return view;
}
String model = Build.MODEL;
String product = Build.PRODUCT;
String androidOS = Build.VERSION.RELEASE;
String scheda = model+"\n"+androidOS+" \n "+product+"";
TextView text = (TextView) findViewById(R.id.textView3);
text.setText(scheda);
private TextView findViewById(int textview3) {
// TODO Auto-generated method stub
return null;
}
}
我什么都不懂。我有三个片段,其中一个叫做 Home,一个 faq 和一个 about。如何更改各种“屏幕”的内容?
