Question

我想获取电话号码表格联系Android手册。我尝试了很多方法，但我无法获得电话号码。我有联系人姓名和状态，但当我尝试获取电话号码时，它不起作用。我的代码是。

public class ContactsAdapter extends GroupingCursorAdapter {
    public static final String[] PROJECTION = new String[] {
        Phone._ID,
        Phone.LOOKUP_KEY,
        Phone.DISPLAY_NAME,
        Phone.CONTACT_STATUS,
        Phone.TIMES_CONTACTED,
        Phone.LAST_TIME_CONTACTED,
        Phone.STARRED,
        Phone.NUMBER

    };
    public static final int COLUMN_PHONE_ID = 0;
    public static final int COLUMN_LOOKUP_KEY = 1;
    public static final int COLUMN_DISPLAY_NAME = 2;
    public static final int COLUMN_CONTACT_STATUS = 3;
    public static final int COLUMN_TIMES_CONTACTED = 4;
    public static final int COLUMN_LAST_TIME_CONTACTED = 5;
    public static final int COLUMN_STARRED = 6;
    public static final int COLUMN_NUMER=7;

    private class ViewCache {
        public final TextView contactName;
        public final TextView contactLastDialed;
        public final TextView contactInformation;
        public final TextView contactCallCount;
        public final ImageView contactImage;
        public final ImageView contactStarred;

        public ViewCache(View base) {
            contactName = (TextView)base.findViewById(R.id.ContactName);
            contactLastDialed = (TextView)base.findViewById(R.id.ContactLastDialed);
            contactInformation = (TextView)base.findViewById(R.id.ContactInformation);
            contactCallCount = (TextView)base.findViewById(R.id.ContactCallCount);
            contactImage = (ImageView)base.findViewById(R.id.ContactImage);
            contactStarred = (ImageView)base.findViewById(R.id.ContactStarred);
        }

    }


    private Resources mResources;
    private AsyncContactImageLoader mAsyncContactImageLoader;
    private boolean mShowCallCounter;

    public ContactsAdapter(Context context, Cursor cursor, AsyncContactImageLoader asyncContactImageLoader) {
        super(context, cursor, Phone.LOOKUP_KEY);

    }


    @Override

        view.setTag(viewCache);

        return view;
    }

    @Override

        final ViewCache viewCache = (ViewCache)view.getTag();

        String displayName = cursor.getString(COLUMN_DISPLAY_NAME);

        }

        status = status.replace('\n', ' ');
        viewCache.contactInformation.setText(status);

            lookupKey = "";
        }
        viewCache.contactImage.setTag(lookupKey); // set a tag for the callback to be able to check, so we don't set the contact image of a reused view
        Drawable d = mAsyncContactImageLoader.loadDrawableForContact(lookupKey, new ImageCallback() {

            @Override

    public void setShowCallCounter(boolean showCallCounter) {

确保您能够获得正确的联系lookupkey。这是我的代码。你可以测试它。

private static final String[] PHONE_PROJECTION = { Phone.NUMBER, };
private static final String PHONE_LOOKUP_KEY_SELECTION = Data.LOOKUP_KEY
            + "=?" + " AND " + Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE
            + "'";
public String getPhoneNumber(String lookupKey) {
        String result = null;
        Cursor cursor = null;
        try {
            cursor = mContext.getContentResolver().query(Data.CONTENT_URI,
                    PHONE_PROJECTION, PHONE_LOOKUP_KEY_SELECTION,
                    new String[] { lookupKey }, null);
            if (cursor != null && cursor.moveToFirst()) {
                result = cursor.getString(0);
            }
        } catch (Exception e) {

        } finally {
            if (cursor != null) {
                cursor.close();
            }
        }
        return result;
    }
