Body
I have a checkbox that can be dynamically disabled and tied to a click listener: <pre><code>CheckBox chkbox = (CheckBox)findViewById(R.id.chkboxid); if(condition) { chkbox.setEnabled(false); chkbox.setOnClickListener(displayPopup); } else { chkbox.setOnClickListener(handleToggle); } </code></pre> The purpose of this is if the checkbox is disabled, I want to give users that click on the checkbox more info about why the option is disabled for them. I have since realized that disabled widgets do not send click events to click listeners. I have since tried setting the <code>LinearLayout</code> it exists in as clickable by doing the following: <pre><code>CheckBox chkbox = (CheckBox)findViewById(R.id.checkboxName); LinearLayout layout = (LinearLayout)findViewById(R.id.layoutName); if(condition) { chkbox.setEnabled(false); layout.setClickable(true); layout.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS); layout.setOnClickListener(displayPopup); } else { chkbox.setOnClickListener(handleToggle); } </code></pre> This works for clicking anywhere inside the <code>LinearLayout</code> except on the disabled checkbox. It is not following the <code>FOCUS_BLOCK_DESCENDANTS</code> setting. I have also tried placing an invisible clickable object over the checkbox but was not successful there either. Any ideas? EDIT: We're stuck in API lvl 8 right now, or otherwise I'd try lowering the alpha of the checkbox instead of disabling it to at least simulate the appearance of being disabled.

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.
