Step1: AndroidManifest.xmlAdd use permissionStep2: resourceresmenupopup_menu.xmlresaluesstrings.xmlUse As RingtoneUse As Ringtone多国语言需要添加在对应的values_xxxxstrings.xml  中Step3:importFileManagerOperationActivity.javaimport android.provider.MediaStore;import android.database.Cursor;import android.content.ContentResolver;import android.content.ContentValues;import android.provider.Settings;import android.widget.Toast;import android.content.ContentUris;import android.media.MediaFile;Step4:显示、隐藏setRingtone菜单 updateEditPopupMenu() 方法改为如下        private void updateEditPopupMenu() {            final Menu menu = mEditPopupMenu.getMenu();            int selectedCount = mAdapter.getCheckedItemsCount();            // remove (disable) protection info icon            menu.removeItem(R.id.protection_info);            if (selectedCount == 0) {                menu.findItem(R.id.rename).setEnabled(false);                menu.findItem(R.id.details).setEnabled(false);                //add                menu.findItem(R.id.set_ringtone).setEnabled(false);            } else if (selectedCount == 1) {                // enable details icon                menu.findItem(R.id.details).setEnabled(true);                // enable rename icon                if (mAdapter.getCheckedFileInfoItemsList().get(0).getFile().canWrite()) {                    menu.findItem(R.id.rename).setEnabled(true);                }                //add                // only audio file can enable set ringtone                FileInfo fileInfo1 = mAdapter.getCheckedFileInfoItemsList().get(0);                if(!fileInfo1.isDrmFile()                         && !fileInfo1.isDirectory()                        && IsMusic(fileInfo1)){                       LogUtils.d(TAG, need set ringtone );                    menu.findItem(R.id.set_ringtone).setEnabled(true);                }else {                    menu.findItem(R.id.set_ringtone).setEnabled(false);                }                                                                // enable protection info icon                FileInfo fileInfo = mAdapter.getCheckedFileInfoItemsList().get(0);                if (fileInfo.isDrmFile()) {                    String path = fileInfo.getFileAbsolutePath();                    if (DrmManager.getInstance().checkDrmObjectType(path)) {                        String mimeType = DrmManager.getInstance().getOriginalMimeType(path);                        if (mimeType != null && mimeType.trim().length() != 0) {                            menu.add(0, R.id.protection_info, 0,                                    com.mediatek.internal.R.string.drm_protectioninfo_title);                        }                    }                }            } else {                // disable details icon                menu.findItem(R.id.details).setEnabled(false);                // disable rename icon                menu.findItem(R.id.rename).setEnabled(false);                //add                menu.findItem(R.id.set_ringtone).setEnabled(false);            }        }            Step5:  .判断选择文件是否是audio 文件定义IsMusic 方法private boolean IsMusic(FileInfo fileinfo ){            String mimeType = fileinfo.getFileMimeType(mService);                int fileType = MediaFile.getFileTypeForMimeType(mimeType);    if (mimeType.startsWith(audio/) || MediaFile.isAudioFileType(fileType)) {        return true;    }else {        return false;    }}Step6:  定义设置ringtone 方法新增方法    setRingtone    public void setRingtone(MenuItem menuItem){            LogUtils.d(TAG, start setRingtone);            FileInfo fileinfo = mAdapter.getCheckedFileInfoItemsList().get(0);                        ContentResolver resolver = getApplicationContext().getContentResolver();            String filepath = fileinfo.getFileAbsolutePath();            Long fileid = 0L;            //Uri fileuri=Uri fileuri= getUriForPath(filepath);            Uri fileuri= MediaStore.Audio.Media.getContentUriForPath(filepath);                        LogUtils.d(TAG, setRingtone uri+fileuri);            LogUtils.d(TAG, setRingtone path+filepath);            Cursor file_cursor = resolver.query(                fileuri,                null,                MediaStore.MediaColumns.DATA+=?,                new String[]{filepath},                null);            if(file_cursor.moveToFirst() && file_cursor.getCount() >0){                String _id = file_cursor.getString(0);                fileid =  Long.valueOf(_id);            }            Uri ringUri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,                fileid);            try {                ContentValues values = new ContentValues(2);                values.put(MediaStore.Audio.Media.IS_RINGTONE, 1);                values.put(MediaStore.Audio.Media.IS_ALARM, 1);                resolver.update(ringUri, values, null, null);            } catch (UnsupportedOperationException ex) {                LogUtils.d(TAG, couldn't set ringtone flag for id  + ringUri);                return;            }                        LogUtils.d(TAG, setRingtone ringUri+ringUri.toString());            String[] cols = new String[] {                    MediaStore.Audio.Media._ID,                    MediaStore.Audio.Media.DATA,                    MediaStore.Audio.Media.TITLE            };                        /// M: use selectionArgs replace set query value in where @{            String where = MediaStore.Audio.Media._ID + =?;            String[] whereArgs = new String[]{String.valueOf(fileid)};            Cursor cursor = resolver.query(                MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,                cols,                 where ,                whereArgs,                null);            /// @}            try {                if (cursor != null && cursor.getCount() == 1) {                    // Set the system setting to make this the current ringtone                    cursor.moveToFirst();                    Settings.System.putString(resolver, Settings.System.RINGTONE, ringUri.toString());                    Toast.makeText(getApplicationContext(), setRingtone Success, Toast.LENGTH_SHORT).show();                }            } finally {                if (cursor != null) {                    cursor.close();                }            }    }Step7:重新定义MediaStore.java getContentUriForPath  方法之所以定义getContentUriForPath，是因为当时开发该feature的时候，发现getContentUriForPath这个函数有bug，当路径是/storage/sdcard1/  时候，无法正确返回uri，返回来的竟然是Internal_content_uri。public static Uri getContentUriForPath(String path) {                return((path.startsWith(Environment.getRootDirectory()+/media))?                INTERNAL_CONTENT_URI :EXTERNAL_CONTENT_URI);            }Step8:响应setRingtone 在onMenuItemClick  方法里面增加            case R.id.set_ringtone:                setRingtone(menuItem);                break;最后编译  ./mk mm ./mediatek/packages/apps/FileManager/
