Android Spinner项目作为网格 [英] Android Spinner items as a grid

问题描述

默认情况下，单击微调框时，项目显示为列表。我想改变显示为网格的项目。
我该怎么做？
我只需要一些方向。

感谢
更新：
这是我的代码。我的控制器下拉显示为多排网格。我附上了这张照片的样子。我也无法选择这些值。

解决方案
您需要覆盖 getDropDownView  Spinner 的方法显示 GridView 。
 
 
 
为了从 Spinner 中选择数值，请在<$ code> OnItemClickListener  c $ c> GridView 来获取回调。例如： 
 
 
  label.setOnItemClickListener（new OnItemClickListener（）{
 public void onItemClick（AdapterView<？> parent ，View v，int pos，long id）{
 Toast.makeText（getContext（），+ pos，Toast.LENGTH_SHORT）.show（）; 
} 
}）; 
  
 
By default when Spinner is clicked, items are showed as list. I want to change the items showed as grid.
How can I do that?
I just need some direction.


Thanks
UPDATE:
This is my code. My spinner drop down is showing up as multiple rows of grid.I have attached a picture of how it looks like at this moment. I am also unable to select the values.

    package com.example.com.android.spinner;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Spinner;
import android.widget.TextView;

public class AndroidCustomSpinner extends Activity {

    String[] DayOfWeek = {"Sunday", "Monday", "Tuesday", 
            "Wednesday", "Thursday", "Friday", "Saturday"};

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Spinner mySpinner = (Spinner)findViewById(R.id.spinner);
        mySpinner.setAdapter(new MyCustomAdapter(AndroidCustomSpinner.this, R.layout.row, DayOfWeek)); 
    }

    public class MyCustomAdapter extends ArrayAdapter<String>{

        private Context context;

        public MyCustomAdapter(Context context, int textViewResourceId,
                String[] objects) {
            super(context, textViewResourceId, objects);
            this.context=context;

            // TODO Auto-generated constructor stub
        }

        @Override
        public View getDropDownView(int position, View convertView,
                ViewGroup parent) {
            // TODO Auto-generated method stub
            return getCustomView(position, convertView, parent);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            TextView label=(TextView)convertView;

              if (convertView==null) {
                convertView=new TextView(context);
                label=(TextView)convertView;
              }

              label.setText(DayOfWeek[position]);

              return(convertView);

        }

        public View getCustomView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            //return super.getView(position, convertView, parent);

            LayoutInflater inflater=getLayoutInflater();
            View row=inflater.inflate(R.layout.row, parent, false);
            GridView label=(GridView)row.findViewById(R.id.gridView1);

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(AndroidCustomSpinner.this,android.R.layout.simple_list_item_1,DayOfWeek);
            label.setAdapter(adapter);


             return row;
        }   
    }

解决方案
You need to override getDropDownView method of your Spinner to show the GridView.

And in order to select values out from your Spinner, use OnItemClickListener on your GridView to get callbacks. for example:
label.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {
        Toast.makeText(getContext(), "" + pos, Toast.LENGTH_SHORT).show();
    }
});
