    text
    copied!<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>
