安卓：添加两个TextViews到动作条微调

问题描述

限时删除！！

反正有添加两个文本观点或串动作条微调里面？

Is there anyway to add two text views or strings inside of the Actionbar Spinner?

类似于如何Android的Gmail应用程序做的。

Similar to how the Android GMAIL app does it.

推荐答案

您可以使用自定义ArrayAdapter：

You could use a custom ArrayAdapter:

public class spinnerAdapter extends ArrayAdapter {
        private LayoutInflater inflater;
        public spinnerAdapter(Context context, int textViewResourceId) {
            super(context, textViewResourceId);
            inflater = LayoutInflater.from(context);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder;

            if(convertView == null){
                holder = new ViewHolder();
                convertView = inflater.inflate(R.layout.spinner_text_layout, null);
                holder.text1 = (TextView)convertView.findViewById(R.id.spinnerText1);
                holder.text2 = (TextView)convertView.findViewById(R.id.spinnerText2);
                convertView.setTag(R.layout.spinner_text_layout, holder);
            } else{
                holder = (ViewHolder)convertView.getTag(R.layout.spinner_text_layout);
            }

            holder.text1.setText("Position: " );
            holder.text2.setText(position);

            return convertView;
            }

        public View getDropDownView(int position, View convertView, ViewGroup parent) {
            ViewHolder2 holder;

            if(convertView == null){
                holder = new ViewHolder2();
                convertView = inflater.inflate(R.layout.spinner_text_layout, null);
                holder.text1 = (TextView)convertView.findViewById(R.id.spinnerText1);
                holder.text2 = (TextView)convertView.findViewById(R.id.spinnerText2);
                convertView.setTag(R.layout.spinner_text_layout, holder);
            } else{
                holder = (ViewHolder2)convertView.getTag(R.layout.spinner_text_layout);
            }

            holder.text1.setText("Position: " );
            holder.text2.setText(position);

            return convertView;
            }

        static class ViewHolder{
            TextView text1;
            TextView text2;
        }

        static class ViewHolder2{
            TextView text1;
            TextView text2;
        }

    }

spinner_text_layout.xml：

spinner_text_layout.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<TextView
    android:id="@+id/spinnerText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="18dp"
    android:layout_marginTop="16dp"
    android:text="Medium Text"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<TextView
    android:id="@+id/spinnerText2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/textView1"
    android:layout_alignParentRight="true"
    android:layout_marginRight="23dp"
    android:text="Medium Text"
    android:textAppearance="?android:attr/textAppearanceMedium" />
