Android how to make View highlight when clicked?

Question

I have a linear layout in which each row is inflated programatically and I want the rows to behave like the ListView when clicked on. That is, I want the row to highlight in the exact same way/colour that the default ListView does. How would I go about doing this?

Solution 1

Ok I have finally figured out how to do this...basically it is done using a selector like the color selector linked by style except instead of 'color' use a drawable for the states and you can refer to the default list drawable that is used in ListView by this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
    android:drawable="@android:drawable/list_selector_background" />      
</selector>

and using this xml as the background for my View.

All the public default drawables can be found here: http://developer.android.com/reference/android/R.drawable.html

Solution 2

I was able to do the same with a text view that I wanted to behave like a list item by using:

<Textview
....
android:background="@android:drawable/list_selector_background"
/>

Solution 3

This might be a good place to start looking.

Although, i would advise you to use the ListView itself, rather than implementing it again.

Solution 4

if you still have a problem with that then please remember that some of UI elements are not clickable (RelativeLayout), so you have to add one more line:

<RelativeLayout 
    ....
    android:clickable="true"
    ...

Solution 5

To your listview set property

android:listSelector="@color/test"

and this test color set any transparent color you like. you can create any transparent color by using hex transparent color

I would use the ListView however I need it NOT to scroll and place it inside a ScrolView and that doesn't seem possible(??)...So I ended up trying to implement my own ListView of sort using a LinearLayout.

and thanks or the link...but would it be possible to reference and use the default ListViews selector element rather than create my own?

you could possibly search for the XML inside the Android Source Code...and just copy it over? i'm not sure if you refer the existing selector,otherwise.

Sorry couldnt figur out which one the ListView uses...anyways I tried creating my own but it doesnt seem to be working but am having problems: I want the whole LinearLayout to highlight so what attribute do I set as the colour selector? I tried using textColour but that doesn't seem to work and background makes it crash since I can only set a drawable or single colour as a background :S

Thanks for sharing back once you found it.

If you're like me and need some background on how to use this kind of selector, read: android-journey.blogspot.com/2009/12/android-selectors.html

Do you happen to know how to keep the textview selected? I have two fragments 1 a listview and 1 a textview of info. Once an item in the listview is selected the item in the textview changes. Is there a way to keep the selected listitem selected?

Good answer. For API 11 and above, use instead android:background="?android:attr/selectableItemBackground". More info here:

..and with appcompat-v7 library you can now use ?attr/selectableItemBackground for backwards compatibility
