Android实现保存图片和视频到系统相册

最近在做图片和视频保存功能，之前做的是保存到sd卡目录下，现在是保存到系统相册中.

废话不多说，直接搞成工具类

public class FileUtils {
    /**
     * 保存图片
     * @param context
     * @param file
     */
    public static void saveImage(Context context, File file) {
        ContentResolver localContentResolver = context.getContentResolver();
        ContentValues localContentValues = getImageContentValues(context, file, System.currentTimeMillis());
        localContentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, localContentValues);

        Intent localIntent = new Intent("android.intent.action.MEDIA_SCANNER_SCAN_FILE");
        final Uri localUri = Uri.fromFile(file);
        localIntent.setData(localUri);
        context.sendBroadcast(localIntent);
    }

    public static ContentValues getImageContentValues(Context paramContext, File paramFile, long paramLong) {
        ContentValues localContentValues = new ContentValues();
        localContentValues.put("title", paramFile.getName());
        localContentValues.put("_display_name", paramFile.getName());
        localContentValues.put("mime_type", "image/jpeg");
        localContentValues.put("datetaken", Long.valueOf(paramLong));
        localContentValues.put("date_modified", Long.valueOf(paramLong));
        localContentValues.put("date_added", Long.valueOf(paramLong));
        localContentValues.put("orientation", Integer.valueOf(0));
        localContentValues.put("_data", paramFile.getAbsolutePath());
        localContentValues.put("_size", Long.valueOf(paramFile.length()));
        return localContentValues;
    }


    /**
     * 保存视频
     * @param context
     * @param file
     */
    public static void saveVideo(Context context, File file) {
        //是否添加到相册
        ContentResolver localContentResolver = context.getContentResolver();
        ContentValues localContentValues = getVideoContentValues(context, file, System.currentTimeMillis());
        Uri localUri = localContentResolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, localContentValues);
        context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, localUri));
    }

    public static ContentValues getVideoContentValues(Context paramContext, File paramFile, long paramLong) {
        ContentValues localContentValues = new ContentValues();
        localContentValues.put("title", paramFile.getName());
        localContentValues.put("_display_name", paramFile.getName());
        localContentValues.put("mime_type", "video/mp4");
        localContentValues.put("datetaken", Long.valueOf(paramLong));
        localContentValues.put("date_modified", Long.valueOf(paramLong));
        localContentValues.put("date_added", Long.valueOf(paramLong));
        localContentValues.put("_data", paramFile.getAbsolutePath());
        localContentValues.put("_size", Long.valueOf(paramFile.length()));
        return localContentValues;
    }
}

注意在注意，保存前，需要权限哦

Manifest.permission.WRITE_EXTERNAL_STORAGE
Manifest.permission.CAMERA,
