我看到了有關如何更改微調的文本顏色許多話題，但我不能瞭解如何使用如何更改微調文本顏色
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="@color/iphone_text" />
我該怎麼真正做到在Java代碼：？ 任何回覆將被認爲是 請儘可能詳細地回答以獲取更多詳細信息
這裏您必須在陣列適配器中設置spinner_item.xml。添加這段代碼在你的java文件
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..
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)
{
}
});
我一個完整的答案是這樣的：
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);
}
}
和 RES /佈局添加新的XML文件：
（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" />
我這樣做如下：我已經使用了getDropDownView()和getView()方法。
使用getDropDownView()打開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;
}
而且使用getView()封閉式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;
}
這是我爲spinner的文本執行的最簡單的方法。我知道它晚了，但它會幫助一個人。
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) {
}
});
從API級別16及以上，您可以使用下面的代碼來更改微調器中的下拉圖標。只需轉到setonItemSelectedListener中的ItemSelected並更改所選的textview的drawable即可。
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) {
}
});
希望它能幫助別人。
建立在noobProgrammer答案上，因爲singleLine已被棄用，所以任何正在尋找答案的人都可以使用spinner_item.xml的快速更新版本。
<?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>
spinner1 in「spinner1 = new ArrayAdapter（this，R.layout.spinner_item，array）;」應該是mAdapter。 –
