XML 中类的使用

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:spinnerMode="dropdown"/>

</LinearLayout>

Java 中类的使用

private CountryCodeSpinner ccs;
ccs = findViewById(R.id.ccs);
ccs.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        CountryCodeSpinner.CountryModel model = (CountryCodeSpinner.CountryModel) parent.getAdapter().getItem(position);
        Log.e("KetanRamani", ": " + model.getPhoneCode());
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});

使用以下代码获取国家/地区代码值

CountryCodeSpinner.CountryModel model = (CountryCodeSpinner.CountryModel) ccs.getSelectedItem();
Log.e("KetanRamani", ": " + model.getPhoneCode() + " " + model.getCountryName());
