Body
I have an OpenGL application, where I fill a two dimensional int List with data, I also Logging the size every time I put data in it. It works grate, there is 236 row. But after I call the method later in the Log it gives me back that the size is 0. Here is how the structur looks like: Main.java <pre><code>... onDrawFrame(GL10 gl) { if (first == true) { // the data comes from another method myList.setData(x, y); // I send the the data for the List // and also log the List size, which at the end is 236 first = false; } myList.check(); // It just Logs the List size, which gives back 0 } ... </code></pre> List.java <pre><code>private List<int[]> dataS = new ArrayList<int[]>(); public void setData(int x, int y) { dataS.add(new int[] { x, y }); Log.i("size", "size: " + dataS.size()); } public void check() { Log.i("check", "check: " + dataS.size()); } </code></pre> I just can't understand what is the problem with it, hope someone can help me. Whole code: Main.java <pre><code>public class Main extends GLSurfaceView implements Renderer { public void drawGame(GL10 gl) { if (firstGameFrame == true) { tMap.setMap(); firstGameFrame = false; } collision.check(); } } </code></pre> Map.java <pre><code>public class Map { public void setMap() { // map1 is an int map1[][] = {{1,0,1}, {1,1,1}, {0,0,1}}; - of course there are more data in it for (int z = 0; z < map1.length; z++) { for (int x = 0; x < map1[z].length; x++) { if (map1[z][x] == 1) { collision.getWall((x*2) - 23, (z * 2) - 27); } } } } } </code></pre> Collision.java <pre><code>public class Collision { private List<Integer[]> wallCoord = new ArrayList<Integer[]>(); public void getWall(int x, int y) { wallCoord.add(new Integer[] { x, y }); Log.i("getwall", "getwall " + x + " " + y + " size " + wallCoord.size()); } public void check() { Log.i("coords", "size: " + wallCoord.size()); } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
