How to add Editext and Button to Efficent Adapter which has a Icon and text
- by jayanthgande
Hi,
I want to create a layout in such a way that on top edittext and button should be there in one row.
The search text I enter in editext and click on search button. Then I want to display a custom list view where each row contains image and text.(As per the API demos example list14 I have tried). But when I run the application, button and edittext are being added to each row (i.e., Each row contains a image, text, editext, button. Can Any one guide how to resolve this issue.
Below is my xml file:
<!--
<FrameLayout android:layout_width="wrap_content"
android:layout_height="0dip" android:layout_weight="1"></FrameLayout>
-->
<ImageView android:id="@+id/icon" android:layout_width="48dip"
android:layout_height="48dip" />
<TextView android:id="@+id/text" android:layout_gravity="center_vertical"
android:layout_width="0dip" android:layout_weight="1.0"
android:layout_height="wrap_content" />
<!--
<EditText android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/prdsearchtb"
android:text="@string/tb_prd_search_lbl"></EditText>
-->
<!--
<TableLayout android:id="@+id/TableLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"> <TableRow>
-->
<Button android:id="@+id/prdsrcbutton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="@string/btn_lbl_prd_search"
android:layout_x="2px" android:layout_y="410px"></Button>
<!-- </TableRow>
</TableLayout>
