android 个人铃声设置代码

1、首先选中列表的铃声

    private void doPickRingtone() {

        Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
        // Allow user to pick 'Default'
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
        // Show only ringtones
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_RINGTONE);
        // Don't show 'Silent'
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);

        Uri ringtoneUri;
        if (mCustomRingtone != null) {
            ringtoneUri = Uri.parse(mCustomRingtone);
        } else {
            // Otherwise pick default ringtone Uri so that something is selected.
            ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
        }

        // Put checkmark next to the current ringtone for this contact
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, ringtoneUri);

        // Launch!
        startActivityForResult(intent, RINGTONE_PICKED);
    }

2、选中之后修改数据库

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) {
            return;
        }

        switch (requestCode) {
            case RINGTONE_PICKED: {
　　　　　　    // 选择完铃声之后获得选中铃音的URI,将其值存入数据库
                Uri pickedUri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
                handleRingtonePicked(pickedUri);
                break;
            }
        }
    }

    private void handleRingtonePicked(Uri pickedUri) {
        if (pickedUri == null || RingtoneManager.isDefault(pickedUri)) {
            mCustomRingtone = null;
        } else {
            mCustomRingtone = pickedUri.toString();
        }
        saveData();
    }

    /**
     * 保存数据
     */
    private void saveData() {
        ContentValues values = new ContentValues();
        values.put(Contacts.CUSTOM_RINGTONE, mCustomRingtone);
        //这里的mContactId是当前联系人的Id
        getContentResolver().update(Contacts.CONTENT_URI, values, Contacts._ID + " = " + mContactId, null) ;
    }
