推荐答案

据我所知，你将不得不使用自定义适配器，并覆盖getDropDown和getView方法。您可以自定义每个项目自定义布局。

As i know, you will have to use a custom adapter, and override the getDropDown and the getView methods. You will be able to customize each item customizing the layout.

嗯......话是很好的，例如更好，尝试这样的事情：

Well... words are good, example better, try something like that :

public class CustomStringArrayAdapter extends ArrayAdapter<String>
{
private Activity    myActivity;

public CustomStringArrayAdapter(Context context, int layoutResourceId, int textViewResourceId, List<String> objects, Activity act)
{
    super(context, layoutResourceId, textViewResourceId, objects);
    this.myActivity = act;
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{
    return getCustomView(position, convertView, parent);
}

public View getCustomView(int position, View convertView, ViewGroup parent)
{
    LayoutInflater inflater = myActivity.getLayoutInflater();
    View row = inflater.inflate(R.layout.spinner_layout, parent, false);
    TextView label = (TextView) row.findViewById(R.id.spinner_textview);
    label.setText(getItem(position));
    LinearLayout layout = (LinearLayout) row.findViewById(R.id.spinner_linear_layout);

    return row;
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    LayoutInflater inflater = myActivity.getLayoutInflater();
    View row = inflater.inflate(R.layout.spinner_layout, parent, false);
    TextView label = (TextView) row.findViewById(R.id.spinner_textview);
    label.setText(getItem(position));

    return row;
    }

}

和布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_gravity="center"
    android:gravity="center"
    android:background="@drawable/transparent"
    android:id="@+id/spinner_linear_layout">
    <TextView
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:gravity="center"
        android:layout_gravity="center"
        android:textSize="21sp"
        android:singleLine="true"
        android:id="@+id/spinner_textview"
        android:textColor="@color/black" />
</LinearLayout>

（但它只是一个样本，如果你要根据不同的选择来调整，你可以在每个对象上添加一个布尔mSelected和更改视图依赖于这个布尔）

(But it's just an sample, if you want to resize depending on the selection, you can add a boolean mSelected on each object and change the view depending on this boolean)

编辑：然后在MultiSpinner：

Edit : Then in the MultiSpinner :

删除这样的：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getContext(),
            android.R.layout.simple_spinner_item,
            new String[] { spinnerText });
    setAdapter(adapter);

和微调添加新的自定义适配器：

and add the new custom adapter in the spinner :

MultiSpinner mMultiSpinner = (MultiSpinner) findViewById(R.id.multispinner);
mMultiSpinner.setAdapter(mCustomArrayAdapter);
