列表视图中添加微调每一行？ [英] listview adding spinner in each row?

问题描述

我现在面临的问题，而在布局将微调。我acctual要求是将微调一次，在布局的顶部。

这个输出我得到：

我有相对布局

 ＆LT;微调
       机器人：ID =@ + ID / spinner1
        机器人：layout_width =FILL_PARENT
   机器人：layout_height =WRAP_CONTENT
   机器人：项=@阵列/ string_array
       机器人：提示=@字符串/ spinner_msg
     /＆GT;
     ＆LT; TextView中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
   机器人：ID =@ + ID / notesTextView
   机器人：layout_width =FILL_PARENT
   机器人：layout_height =WRAP_CONTENT
   机器人：文字颜色=@机器人：彩色/白
   安卓了minHeight =机器人：ATTR /列表preferredItemHeight
   机器人：重力=center_vertical
   机器人：textAppearance =机器人：ATTR / textAppearanceMedium
＆LT; / TextView的＆GT;`
 

MyActivity 类是由 ListActivity 扩展这里的的onCreate 方法

 保护无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;     ListView控件= getListView（）;
     listView.setOnItemClickListener（监听）;
     spinner1 =（微调）findViewById（R.id.spinner1）;
     getDetailsCursor（）;
    的String [] =由新的String [] {db_column};
    INT []为= INT新[] {} R.id.notesTextView;
            curAdapter =新SimpleCursorAdapter（MyActivity.this，R.layout.mylist，空，从，到）;
            setListAdapter（curAdapter）;
        registerForContextMenu（ListView控件）;
    }`
 

解决方案

下面是code在飞旋的列表视图顶部的膨胀：

 的ListView =（ListView控件）findViewById（R.id.list）;        LayoutInflater吹气= LayoutInflater.from（本）;
        查看mTop = inflater.inflate（R.layout.spin，NULL）;
        authorityView.addHeaderView（mTop）;
 

R.layout.spin是只包含微调的布局。
而列表里面，你必须只充气TextView的。如您在mylist.xml正在做的，
只是从中取出微调，并提出了微调seprate XML。

所以微调是一次，在布局（ListView控件）的顶部。

I am facing problem while putting Spinner in layout. My acctual requirement is to place Spinner once, at the top of layout.

This output I am getting:

I have Relative layout

   <Spinner
       android:id="@+id/spinner1"
        android:layout_width="fill_parent"
   android:layout_height="wrap_content" 
   android:entries="@array/string_array"
       android:prompt="@string/spinner_msg"
     />
     <TextView xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/notesTextView" 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content" 
   android:textColor="@android:color/white"
   android:minHeight="?android:attr/listPreferredItemHeight"
   android:gravity="center_vertical"
   android:textAppearance="?android:attr/textAppearanceMedium"
</TextView>`

MyActivity class is extended by ListActivity here's onCreate method

   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

     listView=getListView();
     listView.setOnItemClickListener(listener);
     spinner1=(Spinner)findViewById(R.id.spinner1);
     getDetailsCursor();
    String[] from = new String[] {"db_column"};
    int[] to = new int[] { R.id.notesTextView};
            curAdapter=new SimpleCursorAdapter(MyActivity.this, R.layout.mylist, null, from, to);
            setListAdapter(curAdapter);
        registerForContextMenu(listView);
    }`

解决方案

Here is the code in which spinner inflates on the top of listview :

listView= (ListView) findViewById(R.id.list);

        LayoutInflater inflater = LayoutInflater.from(this);
        View mTop = inflater.inflate(R.layout.spin, null);
        authorityView.addHeaderView(mTop);

R.layout.spin is that layout which contains only spinner. And inside the List you have to inflate textView only. as you are doing in mylist.xml , just remove spinner from it and made seprate xml for spinner.

so spinner is once, at the top of layout (ListView).
