    <p>I am getting data from json parsing from URl and depending on some data from json I need to make the customized list-view button visible otherwise its in invisible state. If condition is like <code>String == "123"</code> then I need to set the button visible. the below code set the button to visible but when i scroll back, it will appear in some other rows as well. Its is not appearing correctly. The button should appear only in row which satisfy the condition. How can solve this?.</p> <p>In my layout I set the button like below:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/list_selector" android:orientation="horizontal" android:padding="5dip" &gt; &lt;!-- ListRow Left side Thumbnail image --&gt; &lt;LinearLayout android:id="@+id/thumbnail" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dip" android:layout_alignParentLeft="true" android:background="@drawable/image_bg" android:layout_marginRight="5dip"&gt; &lt;ImageView android:id="@+id/list_image" android:layout_width="70dip" android:layout_height="70dip" android:src="@drawable/ic_launcher"/&gt; &lt;/LinearLayout&gt; &lt;!-- Title Of program--&gt; &lt;TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/thumbnail" android:layout_toRightOf="@+id/thumbnail" android:text="title Name" android:textColor="#040404" android:typeface="sans" android:textSize="15dip" android:textStyle="bold"/&gt; &lt;!-- category Name --&gt; &lt;TextView android:id="@+id/subtitle" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/title" android:textColor="#343434" android:textSize="10dip" android:layout_marginTop="1dip" android:layout_toRightOf="@+id/thumbnail" android:text="subtitle" /&gt; &lt;!-- start time --&gt; &lt;TextView android:id="@+id/time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/subtitle" android:layout_toRightOf="@+id/thumbnail" android:text="time" android:layout_marginRight="5dip" android:textSize="10dip" android:textColor="#10bcc9" android:textStyle="bold"/&gt; &lt;!-- Rightend button --&gt; &lt;Button android:id="@+id/watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/watchnow" android:layout_alignParentRight="true" android:layout_below="@+id/time" android:layout_centerVertical="true" android:clickable="true" android:focusable="false"/&gt; &lt;/RelativeLayout&gt; </code></pre> <p>And my getView code is like below:</p> <pre><code> public View getView(int position, View convertView, ViewGroup parent) { View vi=convertView; if(convertView==null) vi = inflater.inflate(R.layout.single_row, null); final TextView title = (TextView)vi.findViewById(R.id.title); // title TextView artist = (TextView)vi.findViewById(R.id.subtitle); // artist name TextView duration = (TextView)vi.findViewById(R.id.time); // duration ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image); // thumb image HashMap&lt;String, String&gt; song = new HashMap&lt;String, String&gt;(); song = data.get(position); title.setText(song.get(CustomizedListView.TAG_NAME)); artist.setText(song.get(CustomizedListView.TAG_PR)); duration.setText(song.get(CustomizedListView.TAG_DES)); imageLoader.DisplayImage(song.get(CustomizedListView.TAG_PID), thumb_image); if(duration.getText().toString().equalsIgnoreCase("123456")){ Button watch = (Button)vi.findViewById(R.id.watch); watch.setVisibility(View.VISIBLE); } return vi; } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
