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;

//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 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 (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 contact
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,
ringtoneUri);

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

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 (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 contact intent.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。

@Override
public 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);
}
