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" />

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) {        }                 }
