你也可以修改这个查询亲爱的

cntx.getContentResolver().query(Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select,
                    null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

我维护一个联系人包装器，因此我将所有联系人放在一个数组列表中，其中包含姓名和所有信息，所以现在只需再制作一个您想要显示的联系人姓名列表，只需检查原始联系人并仅显示您想要的那些

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            constants.dismissDialog();

            adapter = new ContactsAdapter(cntx);
            contactsList.setAdapter(adapter);
        }

    }

这是我的联系人包装类

package com.rightbackup.wrapper;

public class ContactsWrapper {

    private long contactId;
    private String displayName,displayNumber,lookUp;
    public boolean checked = true;
    int color_string;

    public ContactsWrapper(long contactId, String displayName, String displayNumber, String lookUp, boolean checked,int color_string) {
        // TODO Auto-generated constructor stub
        this.contactId = contactId;
        this.displayName = displayName;
        this.displayNumber = displayNumber;
        this.lookUp = lookUp;
        this.checked = checked;
        this.color_string =color_string;
    }

    public String getLookUp() {
        return lookUp;
    }

    public int getColor_string() {
        return color_string;
    }

    public boolean isChecked() {
        return checked;
    }

    public long getContactId() {
        return contactId;
    }

    public String getDisplayName() {
        return displayName;
    }

    public String getDisplayNumber() {
        return displayNumber;
    }

    public void setChecked(boolean checked) {
        this.checked = checked;
    }

}
