in which android spinner changes its width according to the data. i want to stop it.

can any one guide me how to achieve this?

any help would be appriciated.

By fixing the width according to the width of screen.

 DisplayMetrics d = new DisplayMetrics(); 
 getWindow().getWindowManager().getDefaultDisplay().getMetrics(d); 
 int wdt = d.widthPixels;
 ddlpostas.getLayoutParams().width = wdt - 120;
 ddlexpiryon.getLayoutParams().width = wdt - 120;

You can use "android:weightSum" on your <TableRow> to adjust the width fixed on the screen.

Example :

<TableRow android:weightSum="2">

            <TextView android:layout_width="0dp"
                android:layout_gravity="center_vertical"
                android:layout_height="wrap_content" android:text="Post As"
                android:layout_weight="1"/>

            <Spinner
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:id="@+id/ddlPostAs"
                android:layout_weight="1"
                />
        </TableRow>

By this code your spinner width will be set as half the width of your TableRow.

Change the values of android:weightSum and android:layout_weight as per your requirement.
