解决小米6.0获取图片地址报错BUG的的办法！

方法是先将图片的url获取到，然后再将url地址转换成图片的储存地址

 

public  String getRealFilePath( final Context context, final Uri uri ) {  //使用此方法就可以将url地址转换成图片的储存地址了
	    if ( null == uri ) return null;
	    final String scheme = uri.getScheme();
	     data2 = null;
	    if ( scheme == null )
	        data2 = uri.getPath();
	    else if ( ContentResolver.SCHEME_FILE.equals( scheme ) ) {
	        data2 = uri.getPath();
	    } else if ( ContentResolver.SCHEME_CONTENT.equals( scheme ) ) {
	        Cursor cursor = context.getContentResolver().query( uri, new String[] { ImageColumns.DATA }, null, null, null );
	        if ( null != cursor ) {
	            if ( cursor.moveToFirst() ) {
	                int index = cursor.getColumnIndex( ImageColumns.DATA );
	                if ( index > -1 ) {
	                    data2 = cursor.getString( index );
	                }
	            }
	            cursor.close();
	        }
	    }
	    return data2;
	}
