java实现自定义适配器代码：

    public class CustomAutoCompleteAdapter extends ArrayAdapter<KeyValueItem> {private Context context;private int resource;List<KeyValueItem> itemList;KeyValueItem KeyValueItem_select=null;public CustomAutoCompleteAdapter(Context context, int resource, List<KeyValueItem> objects) {super(context, resource, objects);this.context = context;this.resource = resource;}
//        @Override
//        public KeyValueItem getItem(int position) {
//            // TODO Auto-generated method stub
//            return itemList.get(position);
//        }
//        @Override
//        public long getItemId(int position) {
//            // TODO Auto-generated method stub
//            return position;
//        }@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// 尝试重用convertView来优化性能if (convertView == null) {LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);convertView = inflater.inflate(resource, parent, false);}TextView textView_Key = convertView.findViewById(R.id.TextView_Key);TextView textView_value = convertView.findViewById(R.id.TextView_value);textView_Key.setText(getItem(position).getKey());textView_value.setText(getItem(position).getValue());textView_Key.setVisibility(View.GONE);// 这里不需要再设置字体大小，因为它已经在布局文件中设置了textView_value.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {KeyValueItem_select=(KeyValueItem)getItem(position);Log.d("data1", "5value:"+KeyValueItem_select.getValue()+"-"+KeyValueItem_select.getKey());AutoCompleteTextView_house.setText(KeyValueItem_select.getValue());AutoCompleteTextView_house.dismissDropDown();AutoCompleteTextView_house.clearFocus();}});textView_Key.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {KeyValueItem_select=(KeyValueItem)getItem(position);Log.d("data1", "6value:"+KeyValueItem_select.getValue()+"-"+KeyValueItem_select.getKey());AutoCompleteTextView_house.setText(KeyValueItem_select.getValue());AutoCompleteTextView_house.dismissDropDown();AutoCompleteTextView_house.clearFocus();}});return convertView;}}public class CustomAutoCompleteLocationAdapter extends ArrayAdapter<KeyValueItem> {private Context context;private int resource;List<KeyValueItem> itemList;KeyValueItem KeyValueItem_select=null;public CustomAutoCompleteLocationAdapter(Context context, int resource, List<KeyValueItem> objects) {super(context, resource, objects);this.context = context;this.resource = resource;}//        @Override
//        public KeyValueItem getItem(int position) {

定义适配器初始化代码：

 CustomAutoCompleteAdapter adapter_house=null;CustomAutoCompleteLocationAdapter adapter_location=null;List<KeyValueItem> itemList=new ArrayList<KeyValueItem>();List<KeyValueItem> itemList_location=new ArrayList<KeyValueItem>();private AutoCompleteTextView AutoCompleteTextView_house;private AutoCompleteTextView AutoCompleteTextView_location_name;
AutoCompleteTextView_house = (AutoCompleteTextView) this.findViewById(R.id.AutoCompleteTextView_house);AutoCompleteTextView_location_name = (AutoCompleteTextView) this.findViewById(R.id.AutoCompleteTextView_location_name);KeyValueItem keyValueItem1=new KeyValueItem("001","仓库1");KeyValueItem keyValueItem2=new KeyValueItem("002","仓库2");KeyValueItem keyValueItem3=new KeyValueItem("003","仓库3");itemList.add(keyValueItem1);itemList.add(keyValueItem2);itemList.add(keyValueItem3);http_GetWarehouse(OrganizationNo);
//       ArrayAdapter<KeyValueItem> arrayAdapter_house2 = new ArrayAdapter<KeyValueItem>(this,
//                R.layout.list_item_layout, itemList );
//        AutoCompleteTextView_house.setAdapter(arrayAdapter_house2);adapter_house = new CustomAutoCompleteAdapter(this, R.layout.list_item_layout, itemList);AutoCompleteTextView_house.setAdapter(adapter_house);ImageButton button_house = (ImageButton) this.findViewById(R.id.ImageButton_house);button_house.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// 显示下拉框AutoCompleteTextView_house.showDropDown();//Log.d("data1", "value:"+AutoCompleteTextView_house.getText().toString());}});AutoCompleteTextView_house.addTextChangedListener(new TextWatcher() {@Overridepublic void beforeTextChanged(CharSequence s, int start, int count, int after) {// Log.d("data1", "2value:"+AutoCompleteTextView_house.getText().toString());}@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count) {//                Log.d("data1", "3value:"+AutoCompleteTextView_house.getText().toString());
//
//                if(adapter2.KeyValueItem_select!=null){
//                    String key= adapter2.KeyValueItem_select.getKey();
//                    Log.d("data1", "3key:"+key);
//                }}@Overridepublic void afterTextChanged(Editable s) {// AutoCompleteTextView_house.clearFocus();Log.d("data1", "4value:"+AutoCompleteTextView_house.getText().toString());if(adapter_house.KeyValueItem_select!=null){String key= adapter_house.KeyValueItem_select.getKey();String value= adapter_house.KeyValueItem_select.getValue();if(key!=null&&key!=""&&key.length()>0){Log.d("data1", "4key:"+key+"-"+value);http_GetLocation(key);warehouse_no2=key;warehouse_name2=value;}else {itemList_location.clear();warehouse_no2="";warehouse_name2="";adapter_location.notifyDataSetChanged();}}}});ImageButton button_location_name = (ImageButton) this.findViewById(R.id.ImageButton_location_name);button_location_name.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// 显示下拉框AutoCompleteTextView_location_name.showDropDown();}});KeyValueItem keyValueItem4=new KeyValueItem("001","仓位1");KeyValueItem keyValueItem5=new KeyValueItem("002","仓位2");KeyValueItem keyValueItem6=new KeyValueItem("003","仓位3");itemList_location.add(keyValueItem4);itemList_location.add(keyValueItem5);itemList_location.add(keyValueItem6);adapter_location = new CustomAutoCompleteLocationAdapter(this, R.layout.list_item_layout, itemList_location);AutoCompleteTextView_location_name.setAdapter(adapter_location);AutoCompleteTextView_location_name.addTextChangedListener(new TextWatcher() {@Overridepublic void beforeTextChanged(CharSequence s, int start, int count, int after) {// Log.d("data1", "2value:"+AutoCompleteTextView_house.getText().toString());}@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count) {//                Log.d("data1", "3value:"+AutoCompleteTextView_house.getText().toString());
//
//                if(adapter2.KeyValueItem_select!=null){
//                    String key= adapter2.KeyValueItem_select.getKey();
//                    Log.d("data1", "3key:"+key);
//                }}@Overridepublic void afterTextChanged(Editable s) {// AutoCompleteTextView_location_name.clearFocus();Log.d("data1", "4仓位value:"+AutoCompleteTextView_location_name.getText().toString());if(adapter_location.KeyValueItem_select!=null){String key= adapter_location.KeyValueItem_select.getKey();String value= adapter_location.KeyValueItem_select.getValue();if(key!=null&&key!=""&&key.length()>0){location_no2=key;location_name2=value;Log.d("data1", "4仓位key:"+key+"-"+value);}else {location_no2="";location_name2="";}}}});

适配器代码：

<?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"  ><TextViewandroid:id="@+id/TextView_value"android:layout_width="match_parent"android:layout_height="30dp"android:layout_weight="1"android:background="@drawable/textview_right_border_simple"android:textAlignment="center"android:textColor="@android:color/black"android:textSize="14sp" /><TextViewandroid:id="@+id/TextView_Key"android:layout_width="wrap_content"android:layout_height="30dp"android:background="@drawable/textview_right_border_simple"android:textAlignment="center"android:textColor="#005500"android:textSize="12sp" /></LinearLayout>

绑定数据实体类

public class KeyValueItem {private String key;private String value;public KeyValueItem() {}public void setKey(String key) {this.key = key;}public void setValue(String value) {this.value = value;}public KeyValueItem(String key, String value) {this.key = key;this.value = value;}public String getKey() {return key;}public String getValue() {return value;}@Overridepublic String toString() {return value; // AutoCompleteTextView显示value}
}

以上就是绑定下拉列表数据代码
