ContentObserver在我的项目中，当联系人表发生更改时，有一段代码正在等待调用。发生这种情况时，我会一一检查表中的每个联系人是否已更改或已创建。然后，根据这一点，我将更改保存在自己的表上。但它给了我错误。这是我的代码：

while (phones.moveToNext()) {
            try {
                name = phones
                        .getString(phones
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                phoneNumber = phones
                        .getString(phones
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                JSONObject jobject = db.select_contact(name, phoneNumber);

                String type1 = jobject.getString("type");

                if (type1.equals("upload")) {
                    Log.i("********", "Upload on the db" + name + "  "
                            + phoneNumber);
                    db.contact_table(name, phoneNumber);
                } else if (type1.equals("change_name")) {
                    db.update_name(name, phoneNumber);
                    Log.i("********", "Change name and upload " + name);
                } else if (type1.equals("change_phone")) {
                    db.update_name(name, phoneNumber);
                    Log.i("********", "Change phone and upload "
                            + phoneNumber);
                }

            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }

还有我把它上传到我自己创建的表的部分：

public long update_name(String name, String number) {
    ContentValues cv = new ContentValues();
    cv.put(NAME, name);
    return ourDatabase.update(DATABASE_TABLE_4, cv, NUMBER + "=" + number,
            null);
}

public long update_number(String name, String number) {
    ContentValues cv = new ContentValues();
    cv.put(NUMBER, number);
    return ourDatabase
            .update(DATABASE_TABLE_4, cv, NAME + "=" + name, null);
}

问题是在数据库上的上传更改部分，它给了我这个错误：

这个：

WHERE phone=+34 629 21 00 80

应该是这样的：

WHERE phone="+34 629 21 00 80"

你的语法是错误的。要在 SQL 中测试字符串值，您应该使用“Like”运算符。

你的 Where 声明应该是这样的：

WHERE phone LIKE "+34 629 21 00 80"

这是正确的答案：

public long update_name(String name, String number) {
    ContentValues cv = new ContentValues();
    cv.put(NAME, name);
    return ourDatabase.update(DATABASE_TABLE_4, cv, NUMBER + " LIKE ?",
        new String[]{number});
}

public long update_number(String name, String number) {
    ContentValues cv = new ContentValues();
    cv.put(NUMBER, number);
    return ourDatabase
        .update(DATABASE_TABLE_4, cv, NAME + " LIKE ?", new String[]{name});
}
