我试图DialogFragment弹出并显示可滚动TextView图例,但它只是切断了图例的其余部分。我无法滚动浏览它或任何东西。我尝试添加 aScrollView但它没有任何作用。这是我得到的屏幕:
这是我的 XML 布局文件:

我运行此命令将内容添加到TextView:
/**
* A dialog that shows the legend of a ArcGISDynamicMapServiceLayer.
*/
public class LegendDialogFragment extends DialogFragment implements View.OnClickListener {
public static final String TAG = LegendDialogFragment.class.getSimpleName();
private LinearLayout mLinearLayout;
private ArcGISDynamicMapServiceLayer mLayer;
private ImageButton backButton;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mLinearLayout = (LinearLayout) inflater.inflate(R.layout.legend_dialog_fragment_layout, null);
getDialog().setTitle(getActivity().getString(R.string.legend));
mLayer = ((MainActivity) getActivity()).getLayer();
backButton = (ImageButton) mLinearLayout.findViewById(R.id.backButton2);
backButton.setOnClickListener(this);
// before we can show the legend we have to fetch the legend info asynchronously
new FetchLegendTask().execute();
return mLinearLayout;
}
public void onAttach(Activity activity) {
super.onAttach(activity);
if (!(activity instanceof MainActivity)) {
throw new IllegalStateException("Hosting activity needs to be of type MainActivity");
}
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.backButton2:
getDialog().dismiss();
break;
}
}
/**
* Retrieves the legend information asynchronously from the ArcGISDynamicMapServiceLayer.
*/
private class FetchLegendTask extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
mLayer.retrieveLegendInfo();
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
for (ArcGISLayerInfo layerInfo : mLayer.getAllLayers()) {
if(layerInfo.isVisible()){
View view = getActivity().getLayoutInflater().inflate(R.layout.layer_legend_layout, null);
populateLegendView(view, layerInfo);
mLinearLayout.addView(view);
}
}
}
private View populateLegendView(View view, ArcGISLayerInfo layerInfo) {
if (layerInfo != null) {
TextView textView = (TextView) view.findViewById(R.id.layer_legend_title_textview);
textView.setText(layerInfo.getName());
}
return view;
}
}

我希望整个内容Fragment可以滚动,但不知道如何实现这一点。每当我尝试包含 a 时ScrollView,它只会滚动该特定一行的其余部分。它不会显示所有内容。我认为这与DialogFragment.
编辑:好的,所以我想我知道为什么它不会滚动。View它在循环中一遍又一遍地调用。然后它填充图层,最后将 添加TextView到LinearLayout. 所以它不一定是“附加”的。所以添加 aScrollView只会使最后一部分可滚动。如果有人知道如何解决这个问题,请告诉我。

也许这很微不足道,但对我来说,在 FrameLayout 内的 Wrapped ScrollView 之后,它开始工作
