Android AutoCompleteTextView无法正确呈现？

Question

您好我有一个AutoCompleteTextView可以在我的Nexus1上正常工作。在Samsung Apollo i5801上部署代码时，列表无法正确显示。数据在列表中，因为我可以滚动一点（见下面的图片）。

这是我的CursorAdapter

class VenueSuggestionLitsAdpater extends CursorAdapter implements
        Filterable {

    private HiTechDatabaseAdapter database;

    public VenueSuggestionLitsAdpater(Context context, Cursor c) {
        super(context, c);

        // database = HiTechDatabaseAdapter.getInstance(JobActivity.this);

        // TODO Auto-generated constructor stub
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        int name = cursor.getColumnIndex("name");
        int postcode = cursor.getColumnIndex("postcode");

        String str = cursor.getString(name) + " - "
                + cursor.getString(postcode);

        ((TextView) view).setText(str);

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        final LayoutInflater inflater = LayoutInflater.from(context);

        final TextView view = (TextView) inflater.inflate(
                android.R.layout.simple_dropdown_item_1line, parent, false);

        int name = cursor.getColumnIndex("name");
        int postcode = cursor.getColumnIndex("postcode");

        String str = cursor.getString(name) + " - "
                + cursor.getString(postcode);

        view.setText(str);

        return view;

    }

    @Override
    public CharSequence convertToString(Cursor cursor) {
        int columnIndex = cursor.getColumnIndexOrThrow("name");
        String name = cursor.getString(columnIndex);
        // Log.d("Debug","Convert To String....");
        return name;

    }

    @Override
    public Cursor runQueryOnBackgroundThread(CharSequence constraint) {

        if (constraint == null) {
            Cursor suggestions = HiTechDatabaseAdapter.getInstance(
                    JobActivity.this).queryVenueName(
                    HiTechDatabaseAdapter.TABLE_VENUES,
                    new String[] { "_id", "name", "address", "postcode","venueID" },
                    "");

            return suggestions;
        }

        Cursor suggestions = HiTechDatabaseAdapter.getInstance(
                JobActivity.this).queryVenueName(
                HiTechDatabaseAdapter.TABLE_VENUES,
                new String[] { "_id", "name", "address", "postcode","venueID" },
                constraint.toString());

        return suggestions;

    }

}

以及如何将我的适配器应用于我的AutoCompleteTextView

VenueSuggestionLitsAdpater suggestionsAdapter = new VenueSuggestionLitsAdpater(
            JobActivity.this, suggestions);
    venuNameSearch.setAdapter(suggestionsAdapter);

最后我的XML布局

非常感谢任何帮助。
