android 解决小米手机上选择照片路径为null情况

昨天测试帅哥说他手机选择图库崩溃了,这是一个上传头像的功能,相信很多应用都有这个功能,于是我就把手机拿过来打log看了下返回的路径 为null,在网上搜索了下解决方案,现在把解决方案记录下：

这是在onActivityResult方法中执行的,

 if (data == null) {
                 return;
             }
             uri = data.getData();
             uri = geturi(data);//解决方案
             String[] proj = { MediaStore.Images.Media.DATA };
             Cursor cursor = managedQuery(uri, proj, null, null, null);
             if(cursor!=null){
                 int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                 cursor.moveToFirst();
                 String path = cursor.getString(column_index);// 图片在的路径
                 Intent intent3 = new Intent(this, SYClipActivity.class);
                 intent3.putExtra("path", path);
                 startActivityForResult(intent3, IMAGE_COMPLETE);
             }

 /**

      public Uri geturi(android.content.Intent intent) {
             Uri uri = intent.getData();
             String type = intent.getType();
             if (uri.getScheme().equals("file") && (type.contains("image/"))) {
                 String path = uri.getEncodedPath();
                 if (path != null) {
                     path = Uri.decode(path);
                     ContentResolver cr = this.getContentResolver();
                     StringBuffer buff = new StringBuffer();
                     buff.append("(").append(Images.ImageColumns.DATA).append("=")
                             .append("'" + path + "'").append(")");
                     Cursor cur = cr.query(Images.Media.EXTERNAL_CONTENT_URI,
                             new String[] { Images.ImageColumns._ID },
                             buff.toString(), null, null);
                     int index = 0;
                     for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) {
                         index = cur.getColumnIndex(Images.ImageColumns._ID);
                         // set _id value
                         index = cur.getInt(index);
                     }
                     if (index == 0) {
                         // do nothing
                     } else {
                         Uri uri_temp = Uri
                                 .parse("content://media/external/images/media/"
                                         + index);
                         if (uri_temp != null) {
                             uri = uri_temp;
                         }
                     }
                 }
             }
             return uri;
         }

在此记录下,
