How to solve this Logcat error java.lang.ArithmeticException: divide by zero in android

Question

I have been working for dynamically creating table layout but I got log error in my code java.lang.ArithmeticException: divide by zero. Code.Where I got error couldn't trigger out from logcat.

  public void servershopimagesoffline() {
     String Specifications = jsonarray;
     try {
         specifi = new JSONArray(Specifications);


     } catch (JSONException e) {
         e.printStackTrace();
     }
     if (specifi.length() > 0) {
         for (int i = 0; i < specifi.length(); i++) {
             try {
                 specification = specifi.getJSONObject(i);
             } catch (JSONException e) {
                 e.printStackTrace();
             }
             TableLayout ll = (TableLayout) findViewById(R.id.maintable);

Remove `View Group` try this `setLayoutParams(new TableRow.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT ));.` — Jay Rathod, May 13 '16 at 12:27
'row.setLayoutParams(new TableRow.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT' And same params 'second' — Petrov Dmitrii, May 13 '16 at 12:27

It is not immediately obvious to me what the problem is, but I have done a bit of research and noticed the following:

The developer docs for TableLayout mention "The children of a TableLayout cannot specify the layout_widthattribute. Width is always MATCH_PARENT". You could try either not setting a width at all, or defaulting to MATCH_PARENT.

Then to follow up on that, in the source code for TableLayout, around line 583 a division is performed with the count as the divisor. Probably what is happening is that the due to you setting the width of TableLayout's children to WRAP_CONTENT, they were not correctly added, hence the count is 0.

What I would suggest otherwise is to insert a breakpoint in TableLayout's onMeasure() and see if this is indeed the case and try to avoid using WRAP_CONTENT.

Good luck and as a final remark I would also suggest to try and avoid this amount of indentation in your code. It is quite straining to read!

where can I change now can u pls suggested that in my code.I tried what you said correction but got same error — kani mozhi, May 13 '16 at 12:55

I think the problem is here

row = new TableRow(this);
row.setLayoutParams(new TableRow.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT));

You should change ViewGroup.LayoutParams to TableLayout.LayoutParams

Try to set `setStretchAllColumns(true)` on the `TableLayout` – Aurelian Cotuna May 13 '16 at 13:24

Finally I got answer to my question, for dyanamic row have to create Layout params

 header[i].setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT))

and for Table Layout create layout params

ll.addView(row,newTableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));`

There is certain rules of Table Layout widget if you set height must be wrap_content,width must me match parent for child layout.
