Question

I am very new to Android development, so I appologise in advance if this is a “noobish” question.

Using a RelativeLayout, I have a ToggleButton with an ID of reminderToggle:

<ToggleButton
    android:id="@+id/reminderToggle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/reminderDesc"
    android:layout_alignBottom="@+id/reminderDesc"
    android:layout_toRightOf="@+id/imageView1"
    android:text="ToggleButton" />

I am using:

ToggleButton reminderToggle = (ToggleButton)findViewById(R.id.reminderToggle);

then later:

if(reminderToggle.isChecked()) {

inside a button onClick listener, inside of onCreate, to see of the ToggleButton is checked. This was all working fine. I don’t know what I did, but now the app crashes when the button is clicked. In LogCat`, I can see

FATAL EXCEPTION: main
java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.ToggleButton
at nz.co.kwiius.park.ParkActivity$4.onClick(ParkActivity.java:139)

Line 139 is:

ToggleButton reminderToggle = (ToggleButton)findViewById(R.id.reminderToggle);

As you can see in the XML, reminderToggle is a ToggleButton. So what’s all this fuss about? 🙂

Thanks in advance,

PS: There is only one thing with id of reminderToggle, which is this ToggleButton

Clean and rebuild it dude. Also make sure you check build automatically always to avoid such problems.
