    <p>I have a ScrollView and I want to insert a user specified number of HorizontalScrollViews. So what user says he wants to have a matrix of 5x5 elements, I want to insert 5 HorizontalScrollViews with 5 EditText objects each. My program adds the first line just as it's supposed to, but the rest not.</p> <pre><code>for (int i = 0; i &lt; number; i++) { LinearLayout ll = new LinearLayout(this); ll.setLayoutParams(par2); HorizontalScrollView row = new HorizontalScrollView(this); row.setLayoutParams(par1); row.addView(ll); for (int j = 0; j &lt; number; j++) { EditText txt = new EditText(this); txt.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); txt.setHint(i+","+j); ll.addView(txt); } latout_in_scrollview.addView(row); } </code></pre> <p>Any ideas why? Thanks!</p> <p>EDIT: The 1:1 code im using</p> <pre><code>LinearLayout dijkstra_rows; FrameLayout.LayoutParams par1 = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); LinearLayout.LayoutParams par2 = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout_dijkstra); dijkstra_rows = (LinearLayout) findViewById(R.id.dijkstra_rows); Bundle extras = getIntent().getExtras(); number = extras.getInt("vertexes"); for (int i = 0; i &lt; number; i++) { LinearLayout ll = new LinearLayout(this); ll.setLayoutParams(par2); HorizontalScrollView row = new HorizontalScrollView(this); row.setLayoutParams(par1); row.addView(ll); for (int j = 0; j &lt; number; j++) { EditText txt = new EditText(this); txt.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); txt.setHint(i+","+j); ll.addView(txt); } dijkstra_rows.addView(row); } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
