我一直无法设置旋转器小部件的颜色。它该如何进行样式设置?
尝试使用此适配器来配置您的下拉列表:
ArrayAdapter<String> adapter =
new ArrayAdapter<String>(Home.Home_Group, R.layout.my_spinner_style, yourstringarray)
{
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
((TextView) v).setTextSize(16);
((TextView) v).setTextColor(
getResources().getColorStateList(R.color.white)
);
return v;
}
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View v = super.getDropDownView(position, convertView, parent);
v.setBackgroundResource(R.drawable.spinner_bg);
((TextView) v).setTextColor(
getResources().getColorStateList(R.color.spinner_text)
);
((TextView) v).setTypeface(fontStyle);
((TextView) v).setGravity(Gravity.CENTER);
return v;
}
};
将此xml添加到您的布局中,
my_spinner_style.xml<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+android:id/text1"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:textColor="#ffffff"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee" />
最后,
spinner.setAdapter(adapter);
Simple and crisp ....
private OnItemSelectedListener your_spinner _name= new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos,
long id) {
((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
}
public void onNothingSelected(AdapterView<?> parent) {
}
};
m_spnDia = (Spinner)findViewById(R.id.spiDia);
TextView oTextView = (TextView)m_spnDia.getChildAt(0);
oTextView.setTextColor(Color.RED);
ArrayAdapter
从布局资源中创建项目视图:final List<String> values = [SPINNER VALUES];
final ArrayAdapter<String> adapter = new ArrayAdapter<>(
activity, R.layout.my_spinner_item, values);
adapter.setDropDownViewResource(R.layout.my_spinner_dropdown_item);
spinner.setAdapter(adapter);
接下来在my_spinner_item.xml
中根据你的需要设置文本样式:
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="@style/my_spinner_item_style"
/>
my_spinner_dropdown_item
用于显示选择列表。
