自动完成下拉列表中需要改变布局 [英] Autocomplete dropdown list needs layout change

问题描述

目前，我有我的应用程序自动完成下拉框，但它似乎字体颜色是一种灰色的，不可见的被填充列表时。第二图为当点击下拉的样子。我怎样才能改变布局的下拉菜单显示列表中的项目为不同的颜色，如黑色？

I currently have an autocomplete dropdown box on my app, but it appears the font color is a sort of grey and not visible when the list is being populated. The second picture shows how the dropdown looks when clicked. How can I change the layout for the dropdown to show the items in the list as a different colour like black?

    AlertDialog.Builder adb = new AlertDialog.Builder(SettingsMain.this);
                LayoutInflater inflater =     SettingsMain.this.getLayoutInflater(); 
                final View searchlayout = inflater.inflate(R.layout.search_friend, null);

                friend_name = (AutoCompleteTextView) searchlayout.findViewById(R.id.friend_name);       
                friend_name.addTextChangedListener(new TextWatcher() {
                    public void afterTextChanged(Editable editable) {

                    }

                    public void beforeTextChanged(CharSequence charSequence, int arg1, int arg2, int arg3) {

                    }

                    public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
                        String text = charSequence.toString();

                            new MyAsyncTask("get").execute("http://10.0.2.2/jamtivia/webservice.php?type=get_friends&username="+text);
                            drop_down_adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_dropdown_item_1line,adapterList);
                            drop_down_adapter.notifyDataSetChanged();
                            friend_name.setAdapter(drop_down_adapter);
                            if (!friend_name.isPopupShowing()) {
                                friend_name.showDropDown();
                            } 


                                for(int i =0;i < adapterList.size();i++)
                                    Log.d("TEXT CHNGE", adapterList.get(i));
                    }
                });

                adb.setView(searchlayout)

               .setPositiveButton("Ok", new DialogInterface.OnClickListener() {  
                    public void onClick(DialogInterface dialog, int whichButton) {  
                        String fname = friend_name.getText().toString();
                        Integer friend_id = null;

                        try{
                            friend_id = adapterListId.get(adapterList.indexOf(fname));
                            Log.d( "ECHO" , "text : " + name +"ID :"+ player_id+ " ID: " + friend_id);
                            String request = "http://10.0.2.2/jamtivia/webservice.php?type=add_friends&friendId="+friend_id+"&playerId="+player_id;
                            new MyAsyncTask("send").execute(request);
                        }catch(Exception e){Log.d( "PROBLEM SENDING" , "text : " + adapterList.indexOf(fname));}
                        return;                  
                       }  
                  })
               .setNegativeButton("Done", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {

                        dialog.cancel(); 
                    }
                }); 

                    adb.show();  

此外，至于你可以在这个片段中code的看到，这是开展这一功能的好办法？

Also, as far as you can see with this snippet of code, is this a good way to carry out this function?

推荐答案

在创建ArrayAdapter，而不是使用predefined布局使用您的自定义布局

While creating ArrayAdapter instead using the predefined layout use your custom layout

像这样

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
 android:id="@+id/cust_view"  
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:textColor="@android:color/white"
    android:background="@drawable/list_style" 
    android:textSize="17sp"
    android:padding="5dp"
    android:gravity="left|center_vertical"/> 

//你可以给你的选择，背景颜色或图片
并给起了个名字你的选择让我们说custom_list.xml

//you can give color or image of your choice as background and give a name as your choice let us say custom_list.xml

在创建适配器使用您的布局像这样

While Creating adapter use your layout like this

 drop_down_adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.custom_list,adapterList);
