调用系统铃声设置

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private static final int REQUEST_CODE_PICK_RINGTONE = 1;//保存铃声的Uri的字符串形式private String mRingtoneUri = null;

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 ringtonesintent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,RingtoneManager.TYPE_RINGTONE);// Don't show 'Silent'intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);Uri ringtoneUri;if (mRingtoneUri != null) {ringtoneUri = Uri.parse(mRingtoneUri);} 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 contactintent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,ringtoneUri);// Launch!// startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);}

2.选择铃声之后作相应的处理，可以存储到数据库。

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {if (resultCode != Activity.RESULT_OK) {return;}switch (requestCode) {case REQUEST_CODE_PICK_RINGTONE: {Uri pickedUri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);handleRingtonePicked(pickedUri);break;}}}private void handleRingtonePicked(Uri pickedUri) {if (pickedUri == null || RingtoneManager.isDefault(pickedUri)) {mRingtoneUri = null;} else {mRingtoneUri = pickedUri.toString();}// get ringtone name and you can save mRingtoneUri for database.if (mRingtoneUri != null) {rintoneNameView.setText(RingtoneManager.getRingtone(this, pickedUri).getTitle(this));} else {rintoneNameView.setText(getString(R.string.default_ringtone));}// ContentValues values = new ContentValues();// values.put(Contacts.CUSTOM_RINGTONE, mRingtoneUri);// //mContactId mean contacts id// getContentResolver().update(Contacts.CONTENT_URI, values,// Contacts._ID + " = " + mContactId, null);}
