如何做到带HINT的Spinner？？

  如题，搜了各大搜索引擎，连国外的都看过了，终于在github发现一个非常好的带hint的spinner，原理也很简单。

 


这里有一个adapter，只要实现了，你的系统spinner便可以完美得到hint。package com.wangzijian.uc.adapter;

import java.util.List;

import com.<pre name="code" class="java">wangzijian.uc.ui.R;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class AnimalAdapter extends ArrayAdapter<String> {
private TextView text;
private Context context;

LayoutInflater layoutInflater;
List<String> list;

public AnimalAdapter(Context context, List<String> list) {
super(context, android.R.layout.simple_spinner_item);
this.context = context;
layoutInflater = LayoutInflater.from(context);
this.list = list;
}

@Override
public int getCount() {

return list.size() - 1;
}

@Override
public long getItemId(int arg0) {

return arg0;
}

@Override
public String getItem(int position) {

return (String) list.get(position);
}

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

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

};

public View getCustomView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = layoutInflater.inflate(
android.R.layout.simple_spinner_item, parent, false);
}
text = (TextView) convertView.findViewById(android.R.id.text1);
if (position == getCount()) {
text.setText("");
text.setHint(getItem(getCount())); // "Hint to be displayed"
} else {
text.setText(getItem(position));
}

return convertView;
}

}
