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");
}
