I have the following compound view which represents a FlashCard and will only be created programmatically.
public class FlashCardView extends LinearLayout {
private FlashCard flashCard;
public FlashCardView(Context context, FlashCard flashCard) {
super(context);
this.flashCard = flashCard;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.flashcard, this);
((TextView)findViewById(R.id.lbl_lesson)).setText(flashCard.getLesson()); //line 23
((TextView)findViewById(R.id.lbl_box)).setText(flashCard.getBox());
}
}
The xml I'm inflating looks like this:
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:layout_weight="1">
<TextSwitcher
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textSwitcher"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/germanText"
android:textSize="24sp"
android:textIsSelectable="false"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/spanishText"
android:textSize="24sp"/>
</TextSwitcher>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/lbl_box"
android:layout_weight="1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/lbl_lesson"
android:layout_weight="1"
android:gravity="right"/>
</LinearLayout>
</merge>
But when trying to find a child view with findViewById() I get the following exception on the first findViewById call:

I also tried this approach:
View v = inflater.inflate(R.layout.flashcard, null, false);
v.findViewById(...)
..and read a lot on SO, but have not found the cause of the problem so far. I'm working with IntelliJ IDEA and also did a rebuild of the project.
update I changed to root element of the flashcard xml to linearlayout and inflate and set the text now as follows and it works. Thanks for all the comments!
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.flashcard, null, false);
TextView tv = (TextView) v.findViewById(R.id.lbl_lesson);
tv.setText(String.valueOf(flashCard.getLesson()));
tv = (TextView) v.findViewById(R.id.lbl_box);
tv.setText(String.valueOf(flashCard.getBox()));
Make sure your method getLesson()
is returning a string
. If it returns int
you would get this exact error because the setText()
method assumes you are trying to set a string resource from R.
Try with ((TextView)findViewById(R.id.lbl_lesson)).setText(Integer.toString(flashCard.getLesson()));
