铃声选择器 - 单选按钮设置

Question

我可以成功调出一个铃声选择器并使用以下代码获得结果uri ...

    selsound_button.setOnClickListener(new OnClickListener()
    {   
        public void onClick(View arg0)
        {
            Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select ringtone for notifications:");
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,RingtoneManager.TYPE_ALARM);
            startActivityForResult( intent, 999);   
        }
    });

...但我没有弄清楚如何做到以下几点:

鉴于我已经知道当前的uri,我希望告诉选择器当前选择它以便它可以突出显示正确的单选按钮.目前,在我按下其中一个之前,根本没有选择任何无线电按钮.

你需要添加

   intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, currenturi);

设置radiobutton

这是您的确切代码.

selsound_button.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            final Uri currentTone= RingtoneManager.getActualDefaultRingtoneUri(YourActivity.this, RingtoneManager.TYPE_ALARM);
            Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_ALARM);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone");
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, currentTone);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
            startActivityForResult(intent, TONE_PICKER);
        }

    });
