如何将字符串生成器数据添加到android中的listview？

Question

我从PHP服务器获取数据，并将其作为字符串构建器读取。现在我想将它添加到listview。我该怎么做？这是我的PHP数据。我想在Listview中显示它

private String convertStreamToString(InputStream is) {
        String line = "";
        StringBuilder total = new StringBuilder();
        BufferedReader rd = new BufferedReader(new InputStreamReader(is));
        try {
            while ((line = rd.readLine()) != null) {

                total.append(line+"\n");
                    }
        } catch (Exception e) {
            Log.v("sat", ""+e);
        }

结果是：

["A","B","C","D","E","F","G"]

现在如何将此数据添加到listview？

Answer 1

如果["A","B","C","D","E","F","G"]属于String[] values

然后使用简单的列表视图适配器

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
              android.R.layout.simple_list_item_1, android.R.id.<textviewname>, values);

    // Assign adapter to ListView
     listView.setAdapter(adapter); 

Answer 2

简单的数组适配器试试这个：

ArrayList<String>arr_list= new ArrayList<String>();
String str=strbuilder.toString();       

String[] str1=str.split(",");
for(int i=0;i<str1.length;i++){

    arr_list.add(str1[i]);
}

System.out.println("values=="+str1);
System.out.println("arr_list=="+arr_list);


        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                      android.R.layout.simple_list_item_1,  arr_list);

            // Assign adapter to ListView
             listView.setAdapter(adapter); 

这里的strbuilder是你的StringBuilder。

convertStreamToStringArrayList 方法...

  public ArrayList<String> convertStreamToString(InputStream is) {
                ArrayList<String> data=new ArrayList<String>();
                String line;
                BufferedReader info = new BufferedReader(new InputStreamReader(is));
                try {
                    while ((line = info.readLine()) != null) {

                            data.add(line);
                            }
                    return data;
                } catch (Exception e) {
                    Log.v("sat", ""+e);
                }
                return null;
               }

您可以使用以下方法：

 listView.setAdapter(new ArrayAdapter<String>(this,
               android.R.layout.simple_list_item_1,  convertStreamToString(YourStream)));

或

ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,convertStreamToString(YourStream));

listView.setAdapter(adapter);

或

ArrayList<String> data=convertStreamToString(YourStream);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,data);
listView.setAdapter(adapter);
