I'm creating a new spinner dynamically, how can I change my list background color?
the current background color is some dark gray:
When I'm changing the spinner's background attribute to white, i'm getting this unwanted situation:
I want it to be transparent in the activity, and only when i'm opening the spinner (press on it), I want the background will be white.
Here is the code that I'm creating the spinner with:
I'm creating the adapter with:
mAdapter = new ArrayAdapter<String>(getApplicationContext(),
R.layout.spinner, R.id.Language, lang);
LinearLayout layoutHolder =
(LinearLayout)findViewById(R.id.RegisterFormLayout);
Spinner spinner = new Spinner(getApplicationContext());
LayoutParams layParams= new
Spinner.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
spinner.setLayoutParams(layParams);
spinner.setAdapter(mAdapter);
spinner.setOnItemSelectedListener(new myOnItemSelectedListener());
if (lang != null)
spinner.setSelection(lang.intValue());
spinnerList.add(spinner);
layoutHolder.addView(spinner);
my spinner.xml layout is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/SpinnerLayout">
<TextView
android:id="@+id/Language"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#ffffff"
android:background="#00ffffff"
android:padding="5dp" />
</LinearLayout>
any suggestion?
Create background color. By default each activity in Android has a white background. To change the background color, first add a new color definition to the colors. xml file in the values resource folder like the following.
I think this requirement can't possible through theme changes. Because Spinner constructor assigns value on popupBackground attr only if you write in layout xml otherwise it will use default theme value. like below
<Spinner
android:id="@+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:popupBackground="@android:color/holo_green_dark" />
// just try changing popup background
