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

回答1:

Here You have to set your spinner_item.xml in your array adapter. Add this piece of code in your .java file

Spinner yourSpinner;
ArrayAdapter<String> yourAdapter;
yourSpinner= (Spinner) findViewById(R.id.yourSpinnerID);
yourSpinner.setAdapter(yourAdapter);
yourAdapter= new ArrayAdapter<String>(this, R.layout.spinner_item, value);
//here value is your items in spinner..

A complete answer for me would be something like:

public class ee extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ww);
        addListenerOnSpinnerItemSelection();

    }

    public void addListenerOnSpinnerItemSelection() {
        ArrayList<String> array = new ArrayList<String>();
        array.add("item0");
        Spinner spinner1;
        ArrayAdapter<String> mAdapter;
        spinner1 = (Spinner) findViewById(R.id.spinner2);
        mAdapter = new ArrayAdapter<String>(this, R.layout.spinner_item, array);
        spinner1.setAdapter(mAdapter);
    }

}

and in res/layout add new xml file:

(in spinner_item.xml)

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="top"
    android:singleLine="true"
    android:textColor="#00f0ff" />

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

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View view,
                int arg2, long arg3) {

            ((TextView) arg0.getChildAt(0)).setTextColor(Color.RED);
        }
        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }
}

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                R.layout.list_row, list);
        spinner.setAdapter(adapter);

list_row.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingTop="5dp"
android:textColor="#000000"
android:textSize="20sp" />

This is the simplest Method which I executed for spinner's text. I know its late but it will help some one.

select_gender.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
  // give the color which ever you want to give to spinner item in this line of code               
            ((TextView)parent.getChildAt(position)).setTextColor(Color.parseColor("#646b99"));
            spinner_selected_gender=gender_list.get(position);
            Toast.makeText(getApplicationContext(),"You selected"+spinner_selected_gender,Toast.LENGTH_SHORT).show();
        }

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

        }
    });

Spinner spnCategory= (Spinner)findViewById(R.id.my_spinner);
..

ArrayAdapter<String> adptSpnCategory = new ArrayAdapter<String>this,R.layout.custom_spinner_item, alCategoryName);
adptSpnCategory.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnCategory.setAdapter(adptSpnCategory);
spnCategory.setOnItemSelectedListener(new OnItemSelectedListener() 
{
 public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) 
 {
 }
 public void onNothingSelected(AdapterView<?> arg0) 
 {
 }
});

I have done this as following: I have used the getDropDownView() and getView() methods.

Use getDropDownView() for opened Spinner.

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
     View view = convertView;
     if (view == null) {
        LayoutInflater vi = (LayoutInflater) activity
                         .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = vi.inflate(R.layout.context_row_icon, null);
     }
     TextView mTitle = (TextView) view.findViewById(R.id.context_label);
     ImageView flag = (ImageView) view.findViewById(R.id.context_icon);               

     mTitle.setText(values[position].getLabel(activity));

     if (!((LabelItem) getItem(position)).isEnabled()) {
          mTitle.setTextColor(activity.getResources().getColor(
               R.color.context_item_disabled));
     } else {
          mTitle.setTextColor(activity.getResources().getColor(
              R.color.context_item));
     }
     return view;
}

And use getView() for closed Spinner.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
     View view = convertView;
     if (view == null) {
         LayoutInflater vi = (LayoutInflater) activity
             .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         view = vi.inflate(R.layout.context_row_icon, null);
     }
     TextView mTitle = (TextView) view.findViewById(R.id.context_label);
     ImageView flag = (ImageView) view.findViewById(R.id.context_icon);

     mTitle.setText(values[position].getLabel(activity));

     mTitle.setTextColor(activity.getResources().getColor(
           R.color.context_item_disabled));

     return view;
}

From the API level 16 and above, you can use following code to change the drop down icon in spinner. just goto onItemSelected in setonItemSelectedListener and change the drawable of textview selected like this.

 spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
      // give the color which ever you want to give to spinner item in this line of code

    //API Level 16 and above only.
            ((TextView)parent.getChildAt(position)).setCompoundDrawablesRelativeWithIntrinsicBounds(null,null,ContextCompat.getDrawable(Activity.this,R.drawable.icon),null);

//Basically itis changing the drawable of textview, we have change the textview left drawable.
            }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
           }
        });

hope it will help somebody.

Building on noobProgrammer answer, as singleLine has been deprecated, a quick updated version of the spinner_item.xml for anyone who is looking for a answer for this.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1">
</TextView>
