Android : 10-08 10:23:40.433: E/MoreInfoHPW_ViewGroup(10127): Parent view is not a TextView

Hi In don't understand why I get this error, Parent view is not a TextView Any help would be appreciated. I have tried a few things but none seem to work.

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast_screen_pass, (ViewGroup)findViewById(R.id.layout_pass));
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setView(layout);
toast.show();

<ImageView 
    android:id="@+id/approval_icn"
    android:layout_height="40dp"
    android:layout_width="40dp"
    android:src="@drawable/approval_icon" 
    android:layout_gravity="center_vertical" >

</ImageView>

<TextView 
    android:id="@+id/pass_txt"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="10dp"
    android:textColor="#FFFFFF"
    android:textSize="20sp" 
    android:text="Congratulations you have passed the quiz" >
</TextView>

</LinearLayout>
