我正在尝试使用自定义布局填充片段内的 listView。但是当我启动应用程序时,没有加载 listview 的内容(这是使用数组适配器获得的)。这是我加载listView的代码:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.activity_start, container, false);
ProfilesDatabaseHelper dbHelper = ac.getDbManager();
ProfileManagerDAO dbDao = ac.getProfileManagerDAO();
//TODO mettere profilehandler dentroo profileapp.
ProfileHandler handler = new ProfileHandler(view.getContext());
Profile profile = handler.getCurrentProfile();
TextView label = (TextView) view.findViewById(R.id.labelvlm);
label.setText("TEST");
if(handler!=null){
label.setText("Ring Volume: " + profile.getRingVolume() + "Max: "
+ handler.getMaxVolume(AudioManager.STREAM_RING));
label.append("\tVoice Call Volume: " + profile.getCallVolume()
+ " Max: " + handler.getMaxVolume(AudioManager.STREAM_VOICE_CALL));
//manager.setStreamVolume(AudioManager.STREAM_VOICE_CALL, 5, 0);
label.append("\tWIFI Status: " + handler.isWifiActive());
}
Ringtone tone = RingtoneManager.getRingtone(view.getContext(), Settings.System.DEFAULT_RINGTONE_URI);
if(tone!=null){
label.append("\n" + tone.getTitle(view.getContext()));
}
SeekBar bar = (SeekBar) view.findViewById(R.id.ringtonevolumeBar);
bar.setMax(handler.getMaxVolume(AudioManager.STREAM_RING));
bar.setProgress(profile.getRingVolume());
ArrayList
if(profiles!=null){
Log.d(TAG, "List size: " + profiles.size());
ListView profileslist = (ListView) view.findViewById(R.id.profileslist);
adapter = new ProfilesArrayAdapter(view.getContext(), R.layout.list_item, profiles);
profileslist.setAdapter(adapter);
// List
// testing.add("Hey");
// testing.add("Hey Do");
// testing.add("Hey It");
// testing.add("Hey Please");
// ArrayAdapter moviesAdapter = new ArrayAdapter
// profileslist.setAdapter(moviesAdapter);
//profileslist.setA
}
return view;
}
这是我的 CustomAdapter 的代码:
public class ProfilesArrayAdapter extends
ArrayAdapter
ArrayList
int resourceId;
Context context;
static class ProfileItemHandler {
TextView profileId;
TextView profileName;
}
public ProfilesArrayAdapter(Context context, int layoutResourceId, ArrayList
super(context, layoutResourceId);
this.context = context;
this.resourceId = layoutResourceId;
this.entries = profiles;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
ProfileItemHandler handler = null;
if(convertView==null){
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(R.layout.list_item, parent, false);
handler = new ProfileItemHandler();
handler.profileId = (TextView) row.findViewById(R.id.profileName);
handler.profileName = (TextView) row.findViewById(R.id.profileId);
row.setTag(handler);
} else {
handler = (ProfileItemHandler) row.getTag();
}
HashMap
for(String cur_entry: entry.keySet()){
handler.profileId.setText(cur_entry);
handler.profileName.setText(entry.get(cur_entry));
}
return row;
}
}
这是列表项布局的 xml:
xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
这里是主要布局:
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_start" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".StartActivity" > android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/labelvlm" android:text="@string/hello_world" /> android:id="@+id/ringtonevolumeBar" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_below="@+id/labelvlm" android:layout_marginTop="122dp" /> android:id="@+id/profileslist" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignLeft="@+id/ringtonevolumeBar" android:layout_below="@+id/ringtonevolumeBar" android:layout_marginTop="68dp" >
我没有收到任何错误消息,但是当我启动应用程序时,listView 中没有显示任何项目,并且我的 Adapter 的方法 getView 永远不会被调用。任何想法?
