Android --Spinner--自定义Spinner

主要参考博客Android 实现自定义Spinner

1、Spinner样式

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#defafd"
    >

    <ListView android:id="@+id/spinner_search_expand_list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:cacheColorHint="@null"
        android:scrollbars="none"
        android:divider="@android:drawable/divider_horizontal_bright"/>

</LinearLayout>

2、需要使用的ListView的Item的样式

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="10dp"
    android:padding="10dp">

        <TextView
            android:id="@+id/search_expand_item_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="gone"/>

        <TextView
            android:id="@+id/search_expand_item"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="center_vertical"
            android:padding="10dp"
            android:layout_weight="1"
            android:textSize="18sp" />

</LinearLayout>

3、ListView的Adapter，这里是使用了两个Layout来配置Adapter

    public View getView(int position, View view, ViewGroup viewGroup) {
        SearchConditionListItem item = getItem(position);

        if (view == null) {
            view = View.inflate(mcontext, layout, null);
            searchConditionTxt = (TextView) view.findViewById(R.id.search_expand_item);
            searchConditionTxtId=(TextView)view.findViewById(R.id.search_expand_item_id);
            //searchConditionItemCheck=(CheckBox)view.findViewById(R.id.search_expand_item_check);
            searchConditionDisplay=(TextView)view.findViewById(android.R.id.text1);
        }

        if(searchConditionTxt != null) {
            searchConditionTxt.setText(item.getExpandName());
        }
        if(searchConditionTxtId != null) {
            searchConditionTxtId.setText(item.getExpandid());
        }

        if(searchConditionDisplay != null){
            searchConditionDisplay.setText(item.getExpandName());
        }
        return view;
    }

4、自定义Dialog

package com.dr.app.drseamoniter.dialog;

import android.app.AlertDialog;
import android.content.Context;
import android.os.Bundle;

/**
 * Created by Administrator on 15-9-11.
 */
public class SearchSelectDialog extends AlertDialog{

    public SearchSelectDialog(Context context, int theme) {
        super(context, theme);
    }

    public SearchSelectDialog(Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

5、自定义的Spinner

    @Override
    public boolean performClick() {
        Context context = getContext();

        final LayoutInflater inflater = LayoutInflater.from(getContext());
        //弹出框视图
        final View view = inflater.inflate(R.layout.spinner_search_condition, null);
        //视图中的List
        final ListView listview = (ListView) view.findViewById(R.id.spinner_search_expand_list);

//        btnOK = (Button) view.findViewById(R.id.search_condition_btnOK);
//        btnCancel = (Button) view.findViewById(R.id.search_condition_btnCancel);
//
//        btnOK.setOnClickListener(new MyOKCancelClickListener());
//        btnCancel.setOnClickListener(new MyOKCancelClickListener());

        //根据ArrayList<>数据源 确定Adapter
        adapters = new SearchConditionListAdapter(context, getList());
        //listview绑定Adapter
        listview.setAdapter(adapters);
        //监听ItemClick
        listview.setOnItemClickListener(this);

        //设置dialog
        dialog = new SearchSelectDialog(context, R.style.dialog);//创建Dialog并设置样式主题

        LayoutParams params = new LayoutParams(650, LayoutParams.FILL_PARENT);
        dialog.setCanceledOnTouchOutside(true);// 设置点击Dialog外部任意区域关闭Dialog
        dialog.show();
        dialog.addContentView(view, params);
        return true;
    }

6、Activity中使用Spinner

private void setAreaConditionSpinner(){
        mareaExpandList =new ArrayList<SearchConditionListItem>();
        SearchConditionListItem item =new SearchConditionListItem("1",牧场");
        mareaExpandList.add(item);
        item=new SearchConditionListItem("2","陆地");
        mareaExpandList.add(item);

        mareaCondition.setList(mareaExpandList);
        mareaConditionAdapter = new SearchConditionListAdapter(this
                , mareaExpandList,android.R.layout.simple_spinner_item);
        mareaCondition.setAdapter(mareaConditionAdapter);
        mareaCondition.setOnItemSelectedListener(new MyAreaSpinnerItemSelectedListener());
        mareaCondition.setPrompt("请选择区域");
    }

    private void setDevConditionSpinner(String areaid){
        mdevExpandList = new ArrayList<SearchConditionListItem>();
        SearchConditionListItem item = new SearchConditionListItem("11","底层");
        mdevExpandList.add(item);
        item=new SearchConditionListItem("12","底层2");
        mdevExpandList.add(item);

        mdevExpandList.add(item);

        mdevCondition.setList(mdevExpandList);
        mdevConditionAdapter = new SearchConditionListAdapter(this
                , mdevExpandList,android.R.layout.simple_spinner_item);
        mdevCondition.setAdapter(mdevConditionAdapter);
        mareaCondition.setPrompt("请选择设备");
    }
