Spinner and to which you can assign your own text and click listener. There's just two steps.Step 1 - define an xml layout for your custom view as follows:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/view_root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="?android:attr/spinnerStyle" >
<include
layout="@android:layout/simple_spinner_item"
android:id="@+id/view_text"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
We'll assume you've saved the above layout in res/layout/spinner_lookalike.xml.Step 2 - create your custom view class as follows:
/**
* This class is essentially a {@link FrameLayout}
* which looks like a {@link Spinner}.
*/
public class SpinnerLookalikeView extends FrameLayout {
private ViewGroup rootView;
private TextView textView;
/**
* Constructor to use when creating View from code.
* */
public SpinnerLookalikeView(Context context) {
super(context);
initialise();
}
/**
* Constructor that is used when inflating View from XML.
* */
public SpinnerLookalikeView(Context context, AttributeSet attrs) {
super(context, attrs);
initialise();
}
/**
* Constructor that is used when inflating View from XML
* and applying a class-specific base style.
* */
public SpinnerLookalikeView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initialise();
}
@Override
public void setOnClickListener(OnClickListener listener) {
rootView.setOnClickListener(listener);
}
/**
* Sets the text shown in this view.
*
* @param text
*/
public void setText(String text) {
textView.setText(text);
}
/**
* Initialisation method to be called by the constructors of this class only.
*/
private void initialise() {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.spinner_lookalike, this);
rootView = (ViewGroup) findViewById(R.id.view_root);
textView = (TextView) findViewById(R.id.view_text);
}
}
That's it! Now you can add this custom view to your activities and assign text and a click listener to it.
