如何在列表视图的内容保存到Android中的文本文件？ [英] how to save contents of a listview to a text file in android?

问题描述

我有了一堆内容的ListView和我想知道我怎么可以保存列表视图为文本文件里面的内容？我拉着所有的内容从数据库中。

I have a listview that has a bunch of content and I want to know how I can save the contents inside the list view as a text file? I am pulling all the content from a database.

推荐答案

尝试数组序列（可以序列，并取回对象）

Try array serialization (you can serialize and get back Objects)

    ObjectOutputStream out;
    Object[] objs = new Object[yourListView.getCount()];

    for (int i = 0 ; i < youeListView.getCount();i++) {
        Object obj = (Object)yourListView.getItemAtPosition(i);
        objs[i] = obj;
    }
    try {
        out = new ObjectOutputStream(
                new FileOutputStream(
                        new File(yourFile.txt)));
        out.writeObject(objs);
        out.flush();
        out.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
