Error : Spinner cannot be cast to EditText

Question

I don't know what's the problem with this layout :

<ImageView
    android:id="@+id/seticonimage"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:adjustViewBounds="true"
    android:contentDescription="@string/description"
    android:scaleType="fitStart"
    android:src="@drawable/cm7_icon" />

<EditText
    android:id="@+id/vsname"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_toLeftOf="@+id/seticonimage"
    android:hint="@string/entername"
    android:inputType="text" />

<EditText
    android:id="@+id/vsdesc"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/vsname"
    android:layout_toLeftOf="@+id/seticonimage"
    android:hint="@string/shrtdesc"
    android:inputType="text" />

<Spinner
    android:id="@+id/spinner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/vsdesc"
    android:layout_toLeftOf="@+id/seticonimage"
    android:prompt="@string/icon_prompt" />

<TextView
    android:id="@+id/spinnerinfo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/spinner"
    android:layout_below="@+id/spinner"
    android:layout_toLeftOf="@+id/seticonimage" />

But it closes with this error :

What am I doing wrong here?

        final View textEntryView = factory.inflate(R.layout.editvslayout,
                null);
        final EditText evsname = (EditText) textEntryView
                .findViewById(R.id.vsname);
        final EditText evsdesc = (EditText) textEntryView
                .findViewById(R.id.vsdesc);
        final Spinner spinner = (Spinner) textEntryView
                .findViewById(R.id.spinner);
        final ImageView i = (ImageView) textEntryView
                .findViewById(R.id.seticonimage);

Answer 1

Using Android Studio / IntelliJ 15 I often have to 'Build/Clean Project' a few times. When that doesn't work (which is fairly often), I end up deleting the Build directory. Then it works. I can't offer a reason why, but I'd love one from IntelliJ. In my case IntelliJ is mixing up the values for view IDs.

Answer 2

If you are using eclipse then goto Project -> Clean hopefully that will resolve the issue. It did resolved for me.

Answer 3

Please clean your project because it may be possible that you had assign an id to Spinner, R.java builds, but later you assign the same name to EditText without building R.java.

As R.java keeps reference of all controls, so at first time you assign to spinner so R.java consider that this id is a spinner but now you assigned it to EditText and R.java is totally unaware until you clean and build .

moral: sometimes you have to build R.java manually

Answer 4

Its seems that you have did code like:

Spinner mSpinner = (EditText) findViewById (R.id.spinner);

Instead, it should be casted properly as:

Spinner mSpinner = (Spinner) findViewById (R.id.spinner);
