java从Android联系人簿获取电话号码

Question

我想从安卓系统的通讯录中获取电话号码。我尝试了很多方法，但都找不到电话号码。我得到了联系人姓名和状态，但当我试图得到电话号码时，它不起作用。 我的密码是

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_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 {

        }

    }

确保您能获得正确的联系人lookupkey。这是我的密码。你可以测试一下

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;
    }
