Question

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>

Answer 1

What you’re doing is modifying the layout it’s using for individual rows, that’s why the buttons are appearing on every row. What you need to do is create an XML file for the main layout with the buttons and textviews, and then nest a ListView in it. For example, create a main.xml file like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

    <LinearLayout android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="Bla"/>

        <EditText android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="Bla"/>

    </LinearLayout>

    <ListView android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
</LinearLayout>

It’s important that the ID of the list view be exactly as above (@android:id/list). If you don’t use that, your customised ‘Efficient Adapter’ won’t be able to find it. Once you’ve done that, you just have to add setContentView(R.layout.main); to your onCreate method right after the super.onCreate(…) line.
