I have a spinner with a style. The style only contains a background for the spinner. The problem is,that no matter which image I use for the background, the text of the spinner is always pushed to the left.
This is the declaration of the Spinner in the XML -
<Spinner
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/minus"
android:layout_width="wrap_content"
android:layout_below="@+id/female"
android:id="@+id/spin"
android:gravity="center"
android:background="@drawable/spin"
android:layout_marginTop="10dip">
</Spinner>
Also, I get a warning under the android:gravity attribute that says it's an unknown XML attribute.
I can't figure why it does that.
Thanks

Use android:textAlignment="center" tag on spinner
<android.support.v7.widget.AppCompatSpinner
android:id="@+id/state"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAlignment="center"/>

I had this problem as well and the accepted answer did not work to me.
If this also applies to you, make sure that no parent layout overrides the gravity of the spinner item. In my case, I had to set the gravity of the entire Spinner to right.

If you want to see the checkboxes in the dropdown menu while using your own layout:
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
mContext, R.array.room_list, R.layout.spinner_layout);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
yourSpinner.setAdapter(adapter);
Please notice the "android" before "R.layout...." in the line where you put the drop down view resource!

Continuing from my last comment above...
The following code modifies the Hello Spinner tutorial application to display the spinner text contents centered horizontally, as seen in the following two screenshots.
res/layout/my_spinner_textview.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/spinnerItemStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" />
public class HelloSpinner extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.planets_array,
// android.R.layout.simple_spinner_item);
R.layout.my_spinner_textview);
// adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
adapter.setDropDownViewResource(R.layout.my_spinner_textview);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
//No other modification needed.
This hopefully provides enough direction to fix the problem.

Add gravity in your xml file...
<Spinner
android:gravity="center">
</Spinner>
Or add gravity in your java code...
Spinner spinner = (Spinner)findViewById(R.id.spinner);
spinner.setGravity(17);
//17 = center
