java - 难以从其他 Activity 获取数据

Question

我可以将数组数据从一个 Activity 传输到另一个 Activity ，但不能将字符串数据传输，我不知道为什么。这是我的主要 Activity :

protected void onClickCityBreak(View v) {
    persons = (EditText) findViewById(R.id.txtPerson);
    days = (EditText) findViewById(R.id.txtDays);
    String p = persons.toString();
    String d = days.toString();
    String [] arrayCityBreak = getResources().getStringArray(R.array.citybreak);
    Intent myintent = new Intent(MainActivity.this, TripActivity.class);
    myintent.putExtra("PERSONS", p);
    myintent.putExtra("DAYS", d);
    myintent.putExtra("PLACES",arrayCityBreak);
    startActivity(myintent);
}

这是我要发送到的其他 Activity :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_trip);

    String person = getIntent().getStringExtra("PERSONS");
    String day = getIntent().getStringExtra("DAYS");

    TextView txtPerson = (TextView) findViewById(R.id.txtViewPersons);
    txtPerson.setText("Persons travelling: " + person);
    TextView txtDay = (TextView) findViewById(R.id.txtViewDays);
    txtDay.setText("Days of traveling: " + day);

    String[] arrayCityBreak = getIntent().getStringArrayExtra("PLACES");
    ArrayAdapter<String> adapterCityBreak = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayCityBreak);
    ListView myview = (ListView) findViewById(R.id.lstView);
    myview.setAdapter(adapterCityBreak);
}

我在应用程序的 TextView 上得到了这个:

android.support.v7.widget.AppCompactEditText{13e7726VFED...CL. ........563,56....#7f0c0059 app:id/txtDays\

对于 txtPerson 也是如此。我也尝试过使用 Bundle

获取 EditText 的内容应该以这种方式完成:

 String p = persons.getText().toString();
 String d = days.getText().toString();
