1.调用系统铃声设置的Intent，界面上会弹出选择铃声的对话框。

//用于选择铃声后作相应的判断标记<br /> private static final int REQUEST_CODE_PICK_RINGTONE = 1;<br /> //保存铃声的Uri的字符串形式<br /> private String mRingtoneUri = null;

private void doPickRingtone() {<br /> Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);<br /> // Allow user to pick 'Default'<br /> intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);<br /> // Show only ringtones<br /> intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,<br /> RingtoneManager.TYPE_RINGTONE);<br /> // Don't show 'Silent'<br /> intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);</p> <p> Uri ringtoneUri;<br /> if (mRingtoneUri != null) {<br /> ringtoneUri = Uri.parse(mRingtoneUri);<br /> } else {<br /> // Otherwise pick default ringtone Uri so that something is<br /> // selected.<br /> ringtoneUri = RingtoneManager<br /> .getDefaultUri(RingtoneManager.TYPE_RINGTONE);<br /> }</p> <p> // Put checkmark next to the current ringtone for this contact<br /> intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,<br /> ringtoneUri);</p> <p> // Launch!<br /> // startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);<br /> startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);<br /> }
2.选择铃声之后作相应的处理，可以存储到数据库。
