android - 图片来自电话簿的所有联系人并在 android 中显示复选框

Question

我想从 Android 电话簿中选择所有联系人，并希望使用光标和 ListView 将它们存储在列表中。这样我就可以在列表中放置复选框以从电话簿中选择多个联系人。

我怎样才能做到这一点？

提前致谢

为此，首先你必须进行自定义布局

 <LinearLayout>
    <TextView ...../>
    <CheckBox....../>
 </LinearLayout>

现在在 java 代码中使用 ContactsContracts 放置代码...

 Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
    "DISPLAY_NAME = '" + NAME + "'", null, null);
if (cursor.moveToFirst()) {
    String contactId =
        cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
    //
    //  Get all phone numbers.
    //
    Cursor phones = cr.query(Phone.CONTENT_URI, null,
        Phone.CONTACT_ID + " = " + contactId, null, null);
    while (phones.moveToNext()) {
        String number = phones.getString(phones.getColumnIndex(Phone.NUMBER));
        int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
        switch (type) {
            case Phone.TYPE_HOME:
                // do something with the Home number here...
                break;
            case Phone.TYPE_MOBILE:
                // do something with the Mobile number here...
                break;
            case Phone.TYPE_WORK:
                // do something with the Work number here...
                break;
            }
    }
    phones.close();
  // put Display name in textview id which is used in Linear Layout...
