一种用在搜索查看变换所述ArrayAdapter到的CursorAdapter [英] Converting an ArrayAdapter to CursorAdapter for use in a SearchView

问题描述

我如何可以转换 ArrayAdapter＆LT;字符串＆GT; 的静态数据成的CursorAdapter 的使用建议监听器搜索查看？ 我已经构建了 ArrayAdapter＆LT;字符串＆GT; 从静态数据（<$ C C $> allString ）

  ArrayAdapter＆LT;字符串＆GT; sea​​rchAdapter =新的ArrayAdapter＆LT;字符串＆GT;（背景下，R.layout.listitem，allString）;
 

和我用它为 MultiAutoCompleteTextView 这与API级设备工作正常，小于11

  MultiAutoCompleteTextView findTextView.setAdapter（searchAdapter）;
 

不过我的目标API的级别是11和API> 10我使用动作条中，我想有一个搜索查看代替。

下面是我曾尝试：它确实表明了动作条与嵌入式搜索查看，但没有给出任何建议，因为它会在 MultiAutoCompleteTextView 。

  @覆盖
公共布尔onCreateOptionsMenu（功能菜单）{
        MenuInflater充气= getMenuInflater（）;

         如果（android.os.Build.VERSION.SDK_INT→10）{
             inflater.inflate（R.menu.menu11，菜单）;
             搜索查看=（搜索查看）menu.findItem（R.id.MENU_SEARCH）.getActionView（）;
             INT []为= {0};
             CursorAdapter的CursorAdapter的=新SimpleCursorAdapter（背景下，R.layout.listitem，空，allBusStopString，到）;
             sea​​rchView.setSuggestionsAdapter（CursorAdapter的）;
             sea​​rchView.setOnSuggestionListener（新OnSuggestionListener（）{

                @覆盖
                公共布尔onSuggestionClick（INT位置）{
                    字符串将selectedItem =（字符串）cursorAdapter.getItem（位置）;
                    Log.v（搜索视图，则selectedItem）;
                    返回false;
                }

                @覆盖
                公共布尔onSuggestionSelect（INT位置）{
                    返回false;
                }
             }）;
         }其他{
             inflater.inflate（R.menu.menu，菜单）;
         }

    返回true;
}
 

解决方案

这是奇怪的 SearchView.setSuggestionsAdapter 接受的CursorAdapter而已。

您可以创建 MatrixCursor 并从String数组的数据填充它。我希望你有小的数据集合。

然后将光标移动到CursorAdapter的。

 的String [] columnNames = {_id，文本}
    MatrixCursor光标=新MatrixCursor（columnNames）;
    。String []数组= getResources（）getStringArray（R.array.allStrings）; //如果字符串的资源
    的String []临时=新的String [2];
    INT标识= 0;
    对于（字符串项：数组）{
        温度[0] = Integer.toString（ID ++）;
            温度[1] =项目;
        cursor.addRow（临时）;
    }
    从字符串= {文本} [];
    INT []到= {R.id.name_entry};
    busStopCursorAdapter =新SimpleCursorAdapter（背景下，R.layout.listentry，光标，从，到）;
 

How can I convert an ArrayAdapter<String> of static data into a CursorAdapter for using Suggestion Listener in SearchView? I have constructed the ArrayAdapter<String> from static data (allString)

ArrayAdapter<String> searchAdapter = new ArrayAdapter<String>(context, R.layout.listitem, allString);

and I use it for an MultiAutoCompleteTextView which works fine in devices with API level less than 11

MultiAutoCompleteTextView findTextView.setAdapter(searchAdapter);

However my target API is level is 11 and for API>10 I use an ActionBar within which I would like to have a SearchView instead.

Here's what I have tried: It does show the ActionBar with the embedded SearchView but does not give any suggestions as it would in the MultiAutoCompleteTextView.

@Override
public boolean onCreateOptionsMenu(Menu menu) {     
        MenuInflater inflater = getMenuInflater();

         if (android.os.Build.VERSION.SDK_INT > 10){
             inflater.inflate(R.menu.menu11, menu);
             searchView = (SearchView) menu.findItem(R.id.MENU_SEARCH).getActionView();
             int[] to = {0};
             CursorAdapter cursorAdapter = new SimpleCursorAdapter(context, R.layout.listitem, null, allBusStopString, to);
             searchView.setSuggestionsAdapter(cursorAdapter);
             searchView.setOnSuggestionListener(new OnSuggestionListener() {

                @Override
                public boolean onSuggestionClick(int position) {
                    String selectedItem = (String)cursorAdapter.getItem(position);
                    Log.v("search view", selectedItem);
                    return false;
                }

                @Override
                public boolean onSuggestionSelect(int position) {
                    return false;
                }
             });  
         }else{
             inflater.inflate(R.menu.menu, menu);
         }

    return true;
}

解决方案

That's strange SearchView.setSuggestionsAdapter accepts CursorAdapter only.

You could create MatrixCursor and fill it with data from String array. I hope you have small data collection.

Then pass the cursor to CursorAdapter.

    String[] columnNames = {"_id","text"}
    MatrixCursor cursor = new MatrixCursor(columnNames);
    String[] array = getResources().getStringArray(R.array.allStrings); //if strings are in resources
    String[] temp = new String[2];
    int id = 0;
    for(String item : array){
        temp[0] = Integer.toString(id++);
            temp[1] = item;
        cursor.addRow(temp);
    }               
    String[] from = {"text"}; 
    int[] to = {R.id.name_entry};
    busStopCursorAdapter = new SimpleCursorAdapter(context, R.layout.listentry, cursor, from, to);
