对话片段不会从布局中膨胀所有内容

Question

我有一个自定义的对话片段搜索结果，我有一个TextView与ListView的标题应该在哪里。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/bg">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/res"
        android:textStyle="bold"
        android:textSize="36sp"
        android:textColor="@color/button"
        />
    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/list" />
</LinearLayout>

这是onCreate对话框

 @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = getActivity().getLayoutInflater();
    View view = (View)inflater.inflate(R.layout.activity_result,null);

然而它没有显示TextView，即使ListView在那里，并被自定义适配器完全填充。

类JSONAdapter扩展BaseAdapter实现ListAdapter {

private final Activity activity;
private final JSONArray jsonArray;
private JSONAdapter(Activity activity, JSONArray jsonArray) {
    assert activity != null;
    assert jsonArray != null;
    this.jsonArray = jsonArray;
    this.activity = activity;
}

@Override public int getCount() {
    return jsonArray.length();
}
@Override public JSONObject getItem(int position) {
    return jsonArray.optJSONObject(position);
}
@Override public long getItemId(int position) {
    JSONObject jsonObject = getItem(position);
    return jsonObject.optLong("id");
}
@Override public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null)
        convertView = activity.getLayoutInflater().inflate(R.layout.simple_list_item, parent,false);
    Double score= 0.0;
    JSONObject jsonObject = getItem(position);
    TextView firstline= (TextView) convertView.findViewById(R.id.firstLine);
    TextView secondline = (TextView) convertView.findViewById(R.id.secondLine);
    TextView confidence = (TextView) convertView.findViewById(R.id.score);
    try {
        firstline.setText(jsonObject.getString("title"));
    } catch (JSONException e) {
        e.printStackTrace();
    }
    try {
        score= Double.valueOf(jsonObject.getString("score"));
        confidence.setText(jsonObject.getString("score"));
    } catch (JSONException e) {
        e.printStackTrace();
    }
    try {
        secondline.setText(jsonObject.getString("text"));
    } catch (JSONException e) {
        e.printStackTrace();
    }
    if (score<=0.1)
    {
        convertView.setBackgroundColor(getResources().getColor(R.color.red));
    }
    if (score>0.1)
    {
        convertView.setBackgroundColor(getResources().getColor(R.color.orangish));
    }
    if (score>=0.3)
    {
        convertView.setBackgroundColor(getResources().getColor(R.color.yellow));
    }
    if (score>=0.5)
    {
        convertView.setBackgroundColor(getResources().getColor(R.color.green));
    }
    return convertView;
}
}

为什么会发生这种情况?

更新:

我还有这个方法

 public static SearchDialogFragment newInstance(String title) {

    SearchDialogFragment frag = new SearchDialogFragment();
    Bundle args = new Bundle();
    args.putString("json", title);
    frag.setArguments(args);
    return frag;
}

Answer 1

传递这里的所有代码

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = (View)inflater.inflate(R.layout.activity_result,null);

到oncreateView()，像这样

@Override
public View onCreateView(LayoutInflater inflater,
        @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.activity_result, container,false);
}

现在一切都好了
