我想基於傳遞的意圖更新片段中的textview,但我不斷收到錯誤。這裏是我的代碼:錯誤膨脹片段xml
public class PlayerDisplayFragment extends Fragment {
public PlayerDisplayFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_player_display, container, false);
String[] playerArray = getArguments().getStringArray("playerArray");
updateText(view,playerArray);
return view;
}
public void updateText (View view , String[] playerArray){
String pName = playerArray[0] + " " + playerArray[1];
TextView playerName = (TextView) view.findViewById(R.id.player_name);
playerName.setText(pName);
}
}
當它試圖執行updateText函數時,代碼崩潰。下面是它指的是XML元素(片段中的XML文件):
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Placeholder"
android:textSize="18sp"
android:id="@+id/player_name"
android:gravity="center">
</TextView>
最後,這裏是錯誤:

這裏是從主要活動:
public class PlayerDisplay extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player_display); <--- THIS IS LINE 13
}
這裏是activity_player_display.xml文件:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/fragment"
android:name="com.example.android.soccerstar.PlayerDisplayFragment"
tools:layout="@layout/fragment_player_display" android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".PlayerDisplay" />
我在哪裏,從飼料的主要片段在陣列中:
Intent intent = new Intent(getActivity(), com.example.android.soccerstar.PlayerDisplay.class);
intent.putExtra("playerArray", playerArray);
startActivity(intent);
你能發佈完整的片段xml代碼嗎? – Jayanth
如果'@ + id/player_name'在**片段** xml中,那麼爲什麼你要在'getActivity()的活動中找到它「。findViewById(R.id.player_name)'?這不是你如何在片段 –
jayanth中獲得觀點 - 這是相當長的。你正在尋找什麼特別的東西? 板球 - 是的,我意識到我絕對做錯了什麼。你將如何解決問題/在片段中獲取視圖? – NBC
