如何仅向选定的联系人应用铃声？

我找到了一种方法来设置适用于所有联系人的默认铃声，但这不是我的目标。

我希望应用程序有一个按钮（“应用要联系的铃声”），当点击该按钮时，会启动activityForResult，显示手机上所有联系人的列表。选择联系人后，联系活动将关闭并返回一个URI给联系人。然后，应用程序需要将选定的铃声应用于该特定联系人。

活动显示和选择联系人的代码已经实现，似乎可以在应用程序上运行。

Answer 1

为此，您可以使用ContactsContract.Contacts列CUSTOM_RINGTONE（这是一个读/写列！）。

Uri contactUri;
ContentValues values = new ContentValues();
values.put(ContactsContract.Contacts.CUSTOM_RINGTONE, 
    newRingtoneUri.toString());
context.getContentResolver().update(contactUri, values, where, args);

此外，您可能会发现this discussion很有用（从那里获取代码）。

我知道这太晚了，但是我在这里发帖是因为上面的一个不适合我

ContentValues values = new ContentValues();

    ContentResolver resolver = getContentResolver();

    File file = new File(Environment.getExternalStorageDirectory() + "/Test/ArjunMovieTelugu.mp3");
    if(file.exists()) {

        Uri oldUri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath());
        resolver.delete(oldUri, MediaStore.MediaColumns.DATA + "=\"" + file.getAbsolutePath() + "\"", null);


        String contact_number = "CONTACT_NUMBER";
        Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, contact_number);

        // The columns used for `Contacts.getLookupUri`
        String[] projection = new String[]{
                ContactsContract.Contacts._ID, ContactsContract.Contacts.LOOKUP_KEY
        };

        Cursor data = getContentResolver().query(lookupUri, projection, null, null, null);

        if (data != null && data.moveToFirst()) {
            data.moveToFirst();
            // Get the contact lookup Uri
            long contactId = data.getLong(0);
            String lookupKey = data.getString(1);
            Uri contactUri = ContactsContract.Contacts.getLookupUri(contactId, lookupKey);

            values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
            values.put(MediaStore.MediaColumns.TITLE, "Beautiful");
            values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
            values.put(MediaStore.Audio.Media.IS_RINGTONE, true);

            Uri uri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath());
            Uri newUri = resolver.insert(uri, values);

            if(newUri != null){
                String uriString = newUri.toString();
                values.put(ContactsContract.Contacts.CUSTOM_RINGTONE, uriString);
                Log.e("Uri String for " + ContactsContract.Contacts.CONTENT_URI, uriString);
                long updated = resolver.update(contactUri, values,null, null);

                Toast.makeText(RingtoneChange.this, "Updated : " + updated, Toast.LENGTH_LONG).show();
            }

            data.close();
        }


    } else {
        Toast.makeText(RingtoneChange.this, "File does not exist", Toast.LENGTH_LONG).show();
    }

注意：我们必须为marsh锦葵添加运行时权限

int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;

private  boolean checkAndRequestPermissions() {
int readExternal = ContextCompat.checkSelfPermission(this, android.Manifest.permission.READ_EXTERNAL_STORAGE);
int writeExternal = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
int readContacts = ContextCompat.checkSelfPermission(this, android.Manifest.permission.READ_CONTACTS);
int writeContacts = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_CONTACTS);

List<String> listPermissionsNeeded = new ArrayList<>();

if (readExternal != PackageManager.PERMISSION_GRANTED) {
    listPermissionsNeeded.add(android.Manifest.permission.READ_EXTERNAL_STORAGE);
}
if (writeExternal != PackageManager.PERMISSION_GRANTED) {
    listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (readContacts != PackageManager.PERMISSION_GRANTED) {
    listPermissionsNeeded.add(android.Manifest.permission.READ_CONTACTS);

}
if (writeContacts != PackageManager.PERMISSION_GRANTED) {
    listPermissionsNeeded.add(android.Manifest.permission.WRITE_CONTACTS);

}

if (!listPermissionsNeeded.isEmpty()){
    ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray
            (new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
    return false;
}
return true;
}

并在清单文件中包含所有这些权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
