Android学习笔记_72_Spinner的用法

一、普通

 1、

<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@android:id/text1"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:ellipsize="marquee"

    android:gravity="left"

    android:paddingLeft="8dip"

    android:singleLine="true"

    android:textSize="12sp"

    android:textStyle="bold"

    android:textColor="@color/gsdk_black"

    android:text="sdf" />

 

2

private String[] method = null;

ArrayAdapter<String> methodAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, method);

methodSpinner = (Spinner) findViewById(R.id.spinner_recharge_type);

moneyAdapter
.setDropDownViewResource(android.R.layout.select_dialog_item);

methodSpinner.setAdapter(methodAdapter);

 二、自定义spinner:

1、配置文件：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:orientation="horizontal" >



    <TextView

        android:id="@+id/tv_spinner_id"

        android:layout_width="60dp"

        android:layout_height="80dp"

        android:visibility="gone" />



    <TextView

        android:id="@+id/tv_spinner_name"

        style="?android:attr/spinnerDropDownItemStyle"

        android:layout_width="match_parent"

        android:layout_height="35dip"

        android:gravity="center_vertical"

        android:paddingLeft="10dp"

        android:textColor="#000"

        android:textSize="@dimen/font_body" />



</LinearLayout>

2、填充数据

List<Map<String, Object>> data = new ArrayList<Map<String, Object>>();

                    for (Project project : linkedList) {

                        Map<String, Object> map = new HashMap<String, Object>();

                        map.put("name", project.getName());

                        map.put("id", project.getId());

                        data.add(map);

                    }                    

                    searchAdapter = new SimpleAdapter(PurchaseActivity.this, data,

                             R.layout.purchase_search_spinner, new String[]{"id","name"},

                             new int[]{R.id.tv_spinner_id,R.id.tv_spinner_name});

                    searchSpinner.setAdapter(searchAdapter);

3、点击事件：注意点击事件是OnItemSelectedListener而不是OnItemClickListener.

   private class SearchSpinnerItemListener implements OnItemSelectedListener{



        @Override

        public void onItemSelected(AdapterView<?> parent, View view,

                int position, long id) {

            Spinner spinner = (Spinner) parent;

            Map<String, Object> projectMap = (Map<String, Object>) spinner.getItemAtPosition(position);

            int pid = Integer.valueOf(projectMap.get("id")+"");

            String pname = (String) projectMap.get("name");

            Log.i("Purchase","pid: "+pid+" pname: "+pname);

            

        }



        @Override

        public void onNothingSelected(AdapterView<?> parent) {

        }

             

    }
