Question

当我将它的适配器更改为从ArrayAdapter扩展的自定义适配器时，我的微调器大小有问题。

如果我以标准方式设置适配器，我会在styles.xml中设置它的样式

ArrayAdapter<String> adapter = new ArrayAdapter<>(context, android.R.layout.simple_spinner_item, spinnerArray);   
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

但我已经为微调器实现了自定义适配器，并以这种方式使用它：

SpinnerImageAndTextAdapter adapter = new SpinnerImageAndTextAdapter(context, spinnerArray, hasItem, arrayIndex);
spinner.setAdapter(adapter);

这是我的Implemented SpinnerImageAndTextAdapter类

public class SpinnerImageAndTextAdapter extends ArrayAdapter<String> {

private static final Integer[] imageArray = {R.drawable.ic_orange, R.drawable.ic_green};

private Context context;
private String[] contentArray;
private String[] arrayIndex;
private boolean hasItem;


public SpinnerImageAndTextAdapter(Context context, String[] objects, boolean hasItem, String[] arrayIndex) {

    super(context, android.R.layout.simple_spinner_item, objects);

    this.context = context;
    this.contentArray = objects;
    this.arrayIndex= arrayIndex;

    this.hasItem= hasItem;
}

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

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

private View getCustomView(int position, View convertView, ViewGroup parent) {

    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        //convertView = inflater.inflate(R.layout.template_spinner_item_image_and_text, null);
        convertView = inflater.inflate(android.R.layout.simple_spinner_dropdown_item, parent, false);
    }

    TextView textView = (TextView) convertView.findViewById(android.R.id.text1);
    textView.setText(contentArray[position]);

    if (hasItem) {
        if (arrayIndex[position].contains("blabla1"))
            textView.setCompoundDrawablesWithIntrinsicBounds(imageArray[0], 0, 0, 0);
        else if (arrayIndex[position].contains("blabla2"))
            textView.setCompoundDrawablesWithIntrinsicBounds(imageArray[1], 0, 0, 0);
    }


    return convertView;


}

这是我对微调器的样式规则

<style name="XTheme.SpinnerGrayStyleSmall" parent="Widget.AppCompat.Spinner">
    <item name="android:layout_width">match_parent</item>
    <item name="android:background">@drawable/edit_text_style_gray</item>
    <item name="android:paddingTop">8dp</item>
    <item name="android:paddingBottom">8dp</item>
    <item name="android:paddingLeft">6dp</item>
    <item name="android:textColor">@color/gray_darker</item>
    <item name="android:textColorHint">@color/gray_darker</item>
</style>

问题：为微调器设置自定义适配器后，是否有任何方法可以防止样式不匹配？

当适配器设置为扩展ArrayAdapter时，Spinner会更改它的大小
