android: CheckedTextView cannot be checked?

Question

Initially I wanted a checkmark where the text is placed on the left of the checkmark. After searching on this site I found out the best workaround is android:CheckedTextView? However, I found out that the checkmark cannot be changed manually by users. Is it by design?

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"   android:id="@+id/autoupdatecheckboxview"   android:layout_width="fill_parent"   android:layout_height="wrap_content"   android:gravity="center_vertical"   android:checkMark="?android:attr/listChoiceIndicatorMultiple"   android:paddingLeft="6dip"   android:paddingRight="6dip"   android:text="Pop up a message when new data available"   android:typeface="sans" android:textSize="16dip"/>

It is possible, and somewhat simple to implement what you are looking for. Yes, CheckedTextView is used primarily for having a single Checkable view in the row of a ListView, which controls its children's checkable states using choiceMode. However, since CheckBox does not appear to support a right-aligned checkbox on its own, and CheckedTextView is a right-aligned checkbox, it makes sense to want to use what's there.

Because ListView controls the checked state of a list item, the CheckedTextView itself does not respond to click events, and is not clickable or focusable by default. It does respond to pressed and focused states, however -- that means it can receive focus and click events, and looks correct as far as a checkbox should look. The only thing missing is that it does not toggle its checked state on click. Therefore, a quick OnClickListener that calls .toggle() will give you the end result you're looking for.

In summary, you need 3 things: clickable, focusable, and onClickListener:

    CheckedTextView chkBox = (CheckedTextView) findViewById(R.id.CheckedTextView01);     chkBox.setOnClickListener(new View.OnClickListener() {         public void onClick(View v)         {             ((CheckedTextView) v).toggle();         }     }); 

and layout file:

<CheckedTextView     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:id="@+id/CheckedTextView01"     android:checked="true"     android:clickable="true"     android:focusable="true"     android:text="Label on Left Side of Checkbox."     />

You probably want to just use a regular CheckBox (which inherits from Button and thus TextView). CheckedTextView is designed to work with list views. Example CheckBox layout XML is below:

<CheckBox     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="Pop up a message when new data available"     android:textSize="16dip" />
