    <p>As title suggests, I have trouble clearing/removing/killing the Layout I set using the setContentView. The problem is seen when I press back button on the screen.</p> <p>Details -</p> <p>From parent layout <code>xyz_parent_layout</code>, I call a method <code>showMeTheImage()</code> which loads the image preview by calling <code>setContentView(yzx_image_layout)</code>. Now to go back to <code>xyz_parent_layout</code>, press on the back button which calls <code>parent.removeView(imageview)</code> but nothing happens. I have also used <code>((ViewManager)imageview.getParent()).removeView(imageview)</code>, this clears the imagepreview but presents a blank screen after that. </p> <p>Another problem is that by pressing back hard key on the imagepreview screen is actually handled on parent screen.</p> <p>I also want to understand how to handle Back hard key press on imageView screen.</p> <p>Not sure what is happening, any help is really appreciated.</p> <p>Update - with code </p> <pre><code>parent = (LinearLayout)mInflater.inflate(R.layout.parent, null); button = (Button)parent.findViewById(R.id.button_dosomething); button.setOnClickListener(new View.OnClickListener() { public void onClick(View buttonView) { showImageView(); } }); context.setContentView(parent); showImageView() { imagePreview = (RelativeLayout)mInflater.inflate(com.xxx.R.layout.yzx_image_layout,null); Button back = (Button)imagePreview.findViewById(com.xxx.R.id.back_button); back.setOnClickListener(new View.OnClickListener() { public void onClick(View backButton) { //Do something } }); parent.addView(imagePreview); context.setContentView(parent); } </code></pre> <p>Thanks, SKU</p>

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.
