Question

我有一个Text Class来自File，因为很长一段时间我不想在一瞬间阅读File！并且ListView当滚动读取时仍然是来自File的数据。兄弟姐妹应该怎么做？

最诚挚的问候，Minallah Tofiq

public class MyText{


    private AssetManager am;
    private InputStream is ;
    private BufferedReader br;
    private String[] text;
    private String Fulltext="";
    private String linetext="";
    public MyText(Context context,String FILE_URL) {
        am = context.getAssets();
        try {
            is = am.open(FILE_URL);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            Log.i("READ", "cannot read from file");
        }
        br=new BufferedReader(new InputStreamReader(is));   
    }
    public void process(){
        try {
            while((linetext=br.readLine())!= null){
                Fulltext+=linetext;
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            Log.i("ERROR", "can't read in process method");
            e.printStackTrace();
        }
        text=Fulltext.split("\\d+");
    }
    public String[] returnString(){
        return this.text;
    }
}

您需要修改此行

while((linetext=br.readLine())!= null)

附加条件。如

while((linetext=br.readLine())!= null && (/*your conditional here*/))

如何实时控制应该读取多少文件
