如何在Spinner Android中设置项目的文本颜色

Question

我在为Spinner设置文本颜色时遇到问题.我见过几个例子,但大多数都有来自strings.xmlin的ArrayAdapter和String数组,res folder因为我的Spinner的项目是从SQLite数据库中检索的,所以我认为它可能无济于事.

这是我的Spinner的代码PersonalInformation.java

public class PersonalInformation extends Activity
{
    EditText txtLikes, txtDislikes, txtType, txtDate;
    Button btnView, btnBack;
    Spinner nameSpinner;    

    final Context context = this;

    private int namesSpinnerId;        

    LikesDBAdapter likeDB = new LikesDBAdapter(this);
    DislikesDBAdapter dlikeDB = new DislikesDBAdapter(this);


    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.info);

        BuddyDBAdapter buddyDB = new BuddyDBAdapter(this);
        buddyDB.open();

        Cursor friendsCursor = buddyDB.getAllNames();
        startManagingCursor(friendsCursor); 

        String[] from = new String[]{BuddyDBAdapter.KEY_NAME};
        int[] to = new int[]{R.id.name};

        SimpleCursorAdapter friendsCursorAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, friendsCursor, from, to);
        friendsCursorAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        nameSpinner = (Spinner)findViewById(R.id.nameSpinner);
        nameSpinner.setAdapter(friendsCursorAdapter);
        //buddyDB.close();


        nameSpinner.setOnItemSelectedListener(new OnItemSelectedListener()
            {
                 @Override
                 public void onItemSelected(AdapterView<?> parent, View view, int pos, long id)
                 {
                     Cursor c = (Cursor)parent.getItemAtPosition(pos);
                     namesSpinnerId = c.getInt(c.getColumnIndexOrThrow(BuddyDBAdapter.KEY_ROWID));
                 }

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

                }
            });
        buddyDB.close();

而且,这些是info.xml中Spinner的布局代码

<Spinner
        style="@style/SpinnerStyle"
        android:id="@+id/nameSpinner"        
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:prompt="@string/friends_prompt"
        android:textColor="@color/green" />

请帮我讲解如何在Spinner中设置项目文本颜色.
我将不胜感激任何帮助.谢谢.!=)

Answer 1

为您的微调器项创建一个xml文件.并将其放在布局文件夹中

spinner_view.xml:


<TextView  
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"
  android:gravity="left"  
  android:textColor="@color/green"         
/>

最后在你的代码中.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_view,yourList);

Answer 2

使用自定义 ArrayAdapter 或自定义 Spinner。
