推荐答案

您必须实施微调的onItemSelected。 像这样的：

You must have implemented onItemSelected of spinner. Like this:

public class YourActivity_Name extends Activity implements
    AdapterView.OnItemSelectedListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    spinner = (Spinner) findViewById(R.id.Spinner1);

    spinner.setOnItemSelectedListener(this);

    }

public void onItemSelected(AdapterView<?> parent, View view, int pos,
        long id) {


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

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub
}


}

更新：

在微调之后，你必须设置项很喜欢这样的：

Then you must have set items in spinner likes this:

ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(
                context, android.R.layout.simple_spinner_item,
                array_spinner);
        adapter.setDropDownViewResource(R.layout.simple_selectable_list_item);
        spinner.setAdapter(adapter);

simple_selectable_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceListItem"
android:gravity="center_vertical"
android:background="?android:attr/listChoiceBackgroundIndicator"
android:paddingLeft="8dip"
android:textColor="#ff0000"
android:paddingRight="8dip"

/>
