如何在 Spinner Android 中设置项目的文本颜色

How to set the items' text color in Spinner Android

提问by Preeyah

I'm having problems with setting text color for the Spinner. I've seen few examples but most have ArrayAdapter and String array from strings.xmlin res folderas my Spinner's items are retrieved from SQLite Database so I think it may not help.

我在为 Spinner 设置文本颜色时遇到问题。我见过的例子很少，但大多数都有 ArrayAdapter 和 String 数组strings.xml，res folder因为我的 Spinner 项目是从 SQLite 数据库中检索的，所以我认为它可能无济于事。

Here are my Spinner's codes PersonalInformation.java

这是我的 Spinner 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();

And, these are Spinner's layout codes in info.xml

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" />

I'll appreciate any help provided. Thanks.! =)

Use Custom ArrayAdapter or Custom Spinner.

使用自定义 ArrayAdapter 或自定义微调器。

Have you seen http://www.coderzheaven.com/2011/02/20/how-to-create-custom-layout-for-your-spinner-in-android-or-customizable-spinner-2/?

你见过http://www.coderzheaven.com/2011/02/20/how-to-create-custom-layout-for-your-spinner-in-android-or-customizable-spinner-2/吗？

Create a xml file for your spinner item. and put it in layout folder

为微调项创建一个 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"         
/>

and finally in your code.

最后在你的代码中。

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

这是 simple_spinner_drowdown_item.xml 的源代码

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1"
    style="?android:attr/spinnerDropDownItemStyle"
    android:singleLine="true"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/dropdownListPreferredItemHeight"
    android:ellipsize="marquee"
    android:textAlignment="inherit"/>

The problem here is ?android:attr/dropdownListPreferredItemHeight is not public, but it seems it is 48 dip or 64dip: https://android.googlesource.com/platform/frameworks/base/+/414c4984fdbb03b688bb5c3c76d20100fce3d067%5E1..414c4984fdbb03b688bb5c3c76d20100fce3d067/

这里的问题是 ?android:attr/dropdownListPreferredItemHeight 不是公开的，但它似乎是 48dip 或 64dip：https://android.googlesource.com/platform/frameworks/base/+/414c4984fdbb03b688bb5c3c76d20100fce3d067485dc603d067816dc603d067816dc78dc78dc78dc70300000

modify the text color create a new xml file in your res/layout folder

修改文本颜色在 res/layout 文件夹中创建一个新的 xml 文件

<TextView android:id="@+id/spinnerText" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:layout_centerHorizontal="true"
    android:textColor="#2f4f4f" 
    android:textSize="20dp" 
    xmlns:android="http://schemas.android.com/apk/res/android"/>

and call adapter similar to like this :

并像这样调用适配器：

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                R.array.spinner_array,
                R.layout.spinner_text);
