    copied!<p>Im building a sudoku and Im facing a performance issue over here.</p> <p>I have this grid an I want to fill the grid with 81 cells. These cells are custom views, because I want them to have 10 labels in them en some function blabla.</p> <p>My problem now is that I have to create 81 subviews (no problem), fill them with data from my model (no problem) and then add the whole grid to my layout (biiiig problem).</p> <p>The whole building is done in a asynctask like this:</p> <pre><code>protected Void doInBackground(Void... params) { Model.Cell[][] sudoku = Controller.getInstance().startNewGame(); //call model for a new game ArrayList&lt;TableRow&gt; rows = ga.generateTable(sudoku); //generate the table tl = new TableLayout(ga); //create tablelayout //add the rows to the layout for (TableRow v : rows) { tl.addView(v); } return null; } </code></pre> <p>Then after this is done:</p> <pre><code>protected void onPostExecute(Void result) { super.onPostExecute(result); RelativeLayout rl = (RelativeLayout) ga.findViewById(R.id.gridContainer); //get the container //create layout rules android.widget.RelativeLayout.LayoutParams params = new android.widget.RelativeLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); params.addRule(RelativeLayout.CENTER_HORIZONTAL); //add the table to the container with the layout rl.addView(tl, params); //this is slow as hell. //stop loading indicator this.loading.dismiss(); } </code></pre> <p>I dont mind get a loading bar for a while. But my loading bar is stopping because rl.addView(tl, params) is superslow.</p> <p>Can somebody please help me how to keep my main thread fast?</p>
