作为一个菜鸟,我发现这个问题的其他答案很难理解。我像这样初始化一个微调器:
mMembership = (Spinner) findViewById(R.id.RegisterMembershipSpinner);
ArrayAdapter<CharSequence> member_adapter = ArrayAdapter.createFromResource(this,
R.array.membership_array, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
member_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
mMembership.setAdapter(member_adapter);
我在layout文件夹中创建了名为spinner_items.xml的XML,其中包含以下内容:
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:gravity="left"
android:textColor="#FFFFFF"
android:padding="5dip"
android:id="@+id/textSpinner"
/>
我应该从这里做些什么才能让我更改微调器项目的文本颜色?
答案 0 :(得分:4)
将android.R.layout.simple_spinner_item
替换为R.layout.spinner_items
并将android:id="@android:id/text1"
添加到您的XML文件
编辑: 如果要更改微调器选定的项目文本颜色。
Spinner mMembership = (Spinner) findViewById(R.id.RegisterMembershipSpinner);
ArrayAdapter<CharSequence> member_adapter = ArrayAdapter.createFromResource(this,
R.array.membership_array, R.layout.spinner_items);
// Specify the layout to use when the list of choices appears
member_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
mMembership.setAdapter(member_adapter);
和spinner_items.xml
的内容:
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:gravity="left"
android:textColor="#FF0000"
android:padding="5dip"
android:id="@android:id/text1"
/>
如果您想更改微调器下拉项文本颜色,则您的java代码为:
mMembership = (Spinner) findViewById(R.id.RegisterMembershipSpinner);
ArrayAdapter<CharSequence> member_adapter = ArrayAdapter.createFromResource(this,
R.array.membership_array, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
member_adapter.setDropDownViewResource(R.layout.spinner_items);
// Apply the adapter to the spinner
mMembership.setAdapter(member_adapter);
和spinner_items.xml
<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content"
android:ellipsize="marquee"
android:textColor="#00FF00"/>
