Enlarge edittext in android by code when click a button

Question

I want to know if its possible to enlarge a EditText in android from 0 until to fill its parent. I tried several things, but in the moment I have the LinearLayout and the EditText is added by code:

    <LinearLayout
        android:id="@+id/ll_buscarenlace"
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="0.8"
        android:gravity="right" >

-

EditText et = (EditText) new EditText(this.act);
LinearLayout ll = (LinearLayout) this.act.findViewById(R.id.ll_buscarenlace);

    et.setWidth(0);
    ll.addView(et);

    for (int i=0; i<=ll.getWidth(); i++){
        et.setWidth(i);
        Thread.sleep(50);

    }

But this is one of many things that I tried to do. Thanks in advance

I don't seem to see any TextView being added? You're adding an EditText not a TextView. Or am I missing something? — Kakalokia, Mar 06 '13 at 21:04
if you have more than one file. Please seperate it while posting here. Readers can't understand which code in which file. — hakki, Mar 06 '13 at 21:09

These are in Layouts folder and src folder, as you know. Sorry, its a EditText, not TextView, Im so tired... This are two separate files, as you know — user1675150, Mar 06 '13 at 21:21
Another issue is Thread.sleep(50); This is very small time value. Because it is in miliseconds. 50ms is equal **0.05** secs When this code work correctly it seems like flash. If you try 5 seconds change value to 5000 — hakki, Mar 06 '13 at 21:36
Why are you set LinearLayout's with to 0? Are not you trying resize EditText? — hakki, Mar 06 '13 at 21:40

By "make it go from zero to fill-parent", do you mean that you want it to initially be invisible and then, on a button click, become visible?

If so, you don't need to do any resizing - in the layout file set android:layout_width="fill_parent" and make it invisible with android:visibility="gone".

Then, in the onClickListener on your button, you can call et.setVisible(Visibility.VISIBLE).

A possible solution: ScaleAnimation.

EditText editText = (EditText) findViewById(R.id.editText1);

Animation scaleAnimation = new ScaleAnimation(0, 1, 1, 1);
scaleAnimation.setDuration(750);
editText.startAnimation(scaleAnimation);

Not exactly what you're looking for since it scales rather than expands, but it may be of help. The effect is not bad either.

Nothing but excellent! Thank you f20k. Anyway, I added a modification to move from right to left: Animation scaleAnimation = new ScaleAnimation(0, 1,1,1,Animation.RELATIVE_TO_SELF,1.0f, Animation.RELATIVE_TO_SELF, 0.5f); – user1675150 Mar 07 '13 at 02:55
