最近开发时遇见小米4，手机选择图库发送图片时崩溃的情况，查看logcat发现cusor查询时为null，查找资料解决此问题，在此记录下：

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);    } }

解决方案如下：

 /**  * 解决小米手机上获取图片路径为null的情况  * @param intent  * @return  */ 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 = getContext().getContentResolver();             StringBuffer buff = new StringBuffer();             buff.append("(").append(MediaStore.Images.ImageColumns.DATA).append("=")                     .append("'" + path + "'").append(")");             Cursor cur = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,                     new String[] { MediaStore.Images.ImageColumns._ID },                     buff.toString(), null, null);             int index = 0;             for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) {                 index = cur.getColumnIndex(MediaStore.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; }
