I have done this using getview method but the problem is that when the Listview is displayed at first time the View does not get hide but when I scroll down and scroll up that time it gets hidden. following is the code snippet. Thanks in advance. public View getView(int position, View convertView, ViewGroup parent) { View v = super.getView(position,

问题 I am working on a project that uses C# generics in combination with the dynamic keyword to implement a simple prototxt Caffe file parser, which is based on the proto2 syntax from the Google protocol buffer project. The parser uses a very simple grammar to read in a prototxt file and store the values in a dictionary of type Dictionary<string, dynamic> . The dynamic objects are used to enable very flexible access to the values and to enable nesting of types, such as Dictionary<string,

问题 I've a form to add External User in which 2 of the fields are not mandatory by default. However, they become mandatory only if one of those fields are filled out. On clicking the apply button, the content of my form is used to generate a dynamic div which gets appended to the 'div.container'. However, it is just disappearing as soon as it is added. What could be the reason for it? Here's the code: var currentPageNo = 0; // Keep track of currently displayed page // Select button that is

问题 this code should create an array in main and then print it but every time I run it I just get an array of all 0s #include <stdio.h> #include <stdlib.h> void print(float **A, int w, int h){ int i, j; A = (float*) malloc(w*h*sizeof(float)); for (i=0;i<h;i++){ A[i] = (float*) malloc(w*sizeof(float)); } for (i=0; i<h; i++){ for(j=0; j<w; j++){ printf("%f ", A[i][j]); } printf("\n"); } } int main(void) { int i; int x_dimension=3; int y_dimension=2; float arr [3][2]={}; arr[0][0]=16.2; print(arr,x

问题 I have an existing Parse database, with several PFObject subclasses. If I want to add a new property to a subclass, an array for example, I add it to the PFObject subclass as an @property and declare it @dynamic in the implementation. I initialise it as empty for new objects. @dynamic newArray; + (instancetype)object { MyObject *myObject = [super object]; myObject.newArray = [NSMutableArray array]; return myObject; } But how can I ensure this is initialised for already existing objects, as

问题 I have posted the similar question before but the solution to this question seems like it will be completely different, thus I hope this does not qualify for a repost. Req: I have 2 columns in a table named SETUPS with the following columns: ID INTEGER NOT NULL RPT_SCRIPT CLOB NOT NULL RPT_SCRIPT has select statements in each record. Below is a statement in the clob column WHERE ID = 1 : SELECT ID, Title, Desc, Type, LVL_CNT, TYPE_10 VALUE_10, TYPE_9 VALUE_9, TYPE_8 VALUE_8, TYPE_7 VALUE_7,

问题 I am running a hive query which selects data from a table and inserts result into another hive partitioned table using spark-sql . While inserting it requires 1536 partitions. But spark is not able to insert data with 1536 partitions eventhough I increased max partitions to 2000. Below is command: spark-sql --master yarn --num-executors 14 --executor-memory 45G --executor-cores 30 --driver-memory 10G --conf spark.dynamicAllocation.enabled=false -e "SET hive.exec.dynamic.partition = true;SET
