How to optimize the listview int android? -

-

In my list view, each item contains some textviews and images, they are defined in the XML layout file 

  Viewholder Contributor; If (convertView == faucet) {convertView = LayoutInflater.from (mContext) .inflate (R.layout.vw_system_notice_list_item, tap);   
 But they can show some pictures of different types, nothing is now being examined in getView method:  
  if (TextUtil.isEmpty (SystemMessage.image)) {viewHolder.img.setVisibility (see GONE); } And {viewHolder.img.setVisibility (see Visual.); }   
 I am thinking, I have created some useless image objects, then  set visibility (see genes) . How do I optimize memory or list view?   
 
 
 two solutions,  
     
  1.  You've already done this, hide Hide on the basis of scenario.  
  2.  
     For this, a little extra effort will be required.  
     a. First create and use an adapter  
     getViewTypeCount (): - Here you will return the number of your list support, such as in your case there are two different layouts with images and text views, and image view Without other  
     getItemViewType: - Here you will have to check this special situation to see what the child's layout should be.    
     Once done, you only need a little extra code in your adapter's getView method, here's a sample code, which you have to expand for yourself, besides, This two, I do not think you have no choice unless you expand the assellistview and make yourself one according to your own needs.  
      Class CustomAdapter BaseAdapter Expanded {@Override public int getCount () {// TODO Auto generated method stub return 0; } @OverWide Public Object Hot Itam (Int Position) {// TODO Auto-generated method stub returns empty; } @ Override Public Long ITMID (Int Position) {// Tudo Auto-Generated Method Stub Return 0; } @ Override Public View getView (int position, seeviewview, ViewGroup Parent) {// You get the type type you want for this type of type = getItemViewType (status); If (convertView == faucet) switch (type) {// fill, populate and return different visual types from here} Return tap; } @ Override Public Intimate Typecount () {// Return the number of different ideas here which you have super. GetViewTypeCount (); } @ Override Public Int ITEM ViewType {// Here you want to use this type of scene, super.getItemViewType (status) for returning to this situation; }} Atlamat hooked this adapter into your list and enjoyed it !!

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
