how do you set the spinner text color?

问题:

I have been unable to set the color on the spinner widget. How is this styled?

回答1:

Try using this adapter for your spinner:

ArrayAdapter<String> adapter = 
    new ArrayAdapter<String>(Home.Home_Group, R.layout.my_spinner_style, yourstringarray)
{

    public View getView(int position, View convertView, ViewGroup parent) {
        View v = super.getView(position, convertView, parent);

        ((TextView) v).setTextSize(16);
        ((TextView) v).setTextColor(
            getResources().getColorStateList(R.color.white)
        );

        return v;
    }

    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        View v = super.getDropDownView(position, convertView, parent);
        v.setBackgroundResource(R.drawable.spinner_bg);

        ((TextView) v).setTextColor(
            getResources().getColorStateList(R.color.spinner_text)
        );

        ((TextView) v).setTypeface(fontStyle);
        ((TextView) v).setGravity(Gravity.CENTER);

        return v;
    }
};

Add this xml to your layout,

my_spinner_style.xml

<?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android" 
        android:id="@+android:id/text1"
        style="?android:attr/spinnerItemStyle"
        android:singleLine="true"
        android:textColor="#ffffff"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ellipsize="marquee" />

And at last,

spinner.setAdapter(adapter);

Simple and crisp ....

private OnItemSelectedListener your_spinner _name= new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos,
            long id) {

        ((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);


    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
};

回答3:

The simplest form is:

m_spnDia = (Spinner)findViewById(R.id.spiDia);
TextView oTextView = (TextView)m_spnDia.getChildAt(0);
oTextView.setTextColor(Color.RED);

If you want to change the text color : Spinner Widgets Text Color

Else, making your own layout is the best way like JoxTraex said.

A shorter alternative to Andro'd answer is to let the ArrayAdapter create the item views for you from a layout resource:

final List<String> values = [SPINNER VALUES];
final ArrayAdapter<String> adapter = new ArrayAdapter<>(
    activity, R.layout.my_spinner_item, values);
adapter.setDropDownViewResource(R.layout.my_spinner_dropdown_item);
spinner.setAdapter(adapter);

Then style your text to suit your needs in my_spinner_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="@style/my_spinner_item_style"
/>

Note: my_spinner_dropdown_item is used when the list of choices appear

For more information read the Spinners documentation.

Try understanding that you are using the dropdown list as provided by the defaults that are available in the SDK.

SIMPLY make your own layout with a custom adapter.
