Question

I want some tips in how to complete one task.

We got three EditTexts, a button and a llistview.

The idea here is when the button is pressed, the texts from the three EditTexts will be show in a listview, side by side, giving the impression that we got a table here.

The problem here is I don’t know how to do it. I’ve tried to search something on the net, but I just got nothing.

I’d really appreciate if you could help.
Thaks for the attention and have a nice day.

There are a couple ways to achieve what you want. If I’m understanding correctly you have a listview and a button. When you click the button, you want 3 editTexts to appear in your listview side by side so that it looks like a table.

The simplest solution is have your list item layout, inflated in your listadapter, simply be a linearlayout with weightSum=”3″ containing 3 edittexts with layout_weight=”1″ and layout_width=”0dp”

so your list_item.xml would look something like:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="3">
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
</LinearLayout>

Then, in the onClick for your button, iterate through the children of the list row and set the visibilities to visible.

As for adding rows dynamically, use a listadapter and a collection and use the notifydatasetchanged to update the list when your collection gains/loses items.
