我有一个需要读取和写入文本文件的应用程序.我有阅读,但我没有写作.我的想法是,当我单击屏幕上的保存按钮时,它会将已放入textviews的所有信息保存到数组中,并将数组的每个段写入文本文件.这是我写作部分的代码:

public class AddOrModify extends Activity {

    private Button Cancelbtn;

    private EditText Address1;
    private EditText City1;
    private EditText State1;
    private EditText Zip1;

            setContentView(R.layout.add_or_modify);

            Savebtn = (Button)findViewById(R.id.savebtn);
            Savebtn.setOnClickListener(new btnlistenersave());

            Cancelbtn = (Button)findViewById(R.id.cancelbtn);
            Cancelbtn.setOnClickListener(new btnlistenercancel());

        }

        private class btnlistenersave implements View.OnClickListener{
            public void onClick(View v) {

                NameofRoute = (EditText)findViewById(R.id.NameofRoute);
                Address1 = (EditText)findViewById(R.id.editAddress1);
                City1 = (EditText)findViewById(R.id.City1);
                State1= (EditText)findViewById(R.id.State1); …
