从文本文件的android负荷微调 [英] load spinner from text file android

问题描述

我在一个项目中工作，以填补从文本文件中微调的资产或SD卡。我的code是

i'm working on a project to fill spinner from text file in assets or sdcard. My code is

BufferedReader in = new BufferedReader(new FileReader("product.txt"));

        String line = in.readLine();
        int index = 0;
        while (line != null) {

            str[index++] = line;
            line = in.readLine();
        }

        Spinner spinner = (Spinner) findViewById(R.id.spinner);
        ArrayAdapter adapter = new ArrayAdapter(this,
                android.R.layout.simple_spinner_item, str);

        spinner.setAdapter(adapter);

和main.xml中

<Spinner
       android:id="@+id/spinner"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
 />

任何人都可以请帮我解决这个问题呢？在此先感谢

Can anyone please help me to solve this issue? Thanks in advance

推荐答案

如果你的文件是在资产文件夹你的项目，我认为你必须做的：

If your file is in the assets folder of you project, I think you have to do:

Vector<String>str=new Vector<String>();
BufferedReader in = new BufferedReader(new InputStreamReader(getAssets().open("product.txt"));

    String line = in.readLine();
    int index = 0;
    while (line != null) {

        str.add(line);
        line = in.readLine();
    }

    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter adapter = new ArrayAdapter(this,
            android.R.layout.simple_spinner_item, str);

    spinner.setAdapter(adapter);

然后你右键点击Eclipse中的资产目录，然后选择构建路径 - >用作源文件夹。

Then you have to right click on the assets directory in Eclipse then choose Build Path -> Use as Source Folder.
