时间/日期对话框.尝试添加按钮.Eclipse Android

Question

所以我用textViews、editTexts、日期对话框和时间对话框选择器制作了一个"活动"。加上一个按钮。

我用它来让日期/时间对话框工作：

private static final int DATE_DIALOG_ID=1; // for date 
  private static final  int TIME_DIALOG_ID=2; // for month 
  private int d,mo,y,h,m; // for date & month variables 
  Button b1,b2; // button objects 
  TextView e1,e2;  // textview objects
  // execution starts from here 
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_rainbowbook);  // calling activity_rainbowbook.xml 
     e1=(TextView)findViewById(R.id.textview1); // getting textview1 id from activity_rainbowbook.xml 
     b1=(Button)findViewById(R.id.button1); // getting  button id from activity_rainbowbook.xml
   b1.setOnClickListener(new OnClickListener() // setting listener for button one  
   {
   public void onClick(View arg0) {

    // TODO Auto-generated method stub
    showDialog(DATE_DIALOG_ID);   // generating dialog box 
     }
  });
  final Calendar cal=Calendar.getInstance(); // allocating memory for calendar instance
   d=cal.get(Calendar.DAY_OF_MONTH); // present date        
  mo=cal.get(Calendar.MONTH); // present month
     y=cal.get(Calendar.YEAR); // present year
     updateDate();  // update date 
  b2=(Button)findViewById(R.id.button2); // getting listener for button2 
   e2=(TextView)findViewById(R.id.textview2); 
   b2.setOnClickListener(new OnClickListener() // setting listener for button2 
   {
    public void onClick(View arg0) {

    // TODO Auto-generated method stub
    showDialog(TIME_DIALOG_ID);
 }
});
  h=Calendar.getInstance().get(Calendar.HOUR); // getting  present hour & minute
  m=Calendar.getInstance().get(Calendar.MINUTE);
  updateTime();  // updating time 
}

public void updateTime()
{
   e2.setText(new StringBuilder().append(h).append(':').append(m));
}
public void updateDate()
{
   e1.setText(new StringBuilder().append(d).append('/').append(mo+1).append('/').append(y));
  }

private DatePickerDialog.OnDateSetListener datelistener=new DatePickerDialog.OnDateSetListener() 
{

   public void onDateSet(DatePicker view,int year, int monthofyear, int day) 
   {
                     y=year;
                     mo=monthofyear;
                     d=day;
                     updateDate();
  }
 };
  private TimePickerDialog.OnTimeSetListener timelistener=new TimePickerDialog.OnTimeSetListener() 
  {
   public void onTimeSet(TimePicker view, int hourofday, int minute) 
   {
    // TODO Auto-generated method stub
    h=hourofday;
    m=minute;
     updateTime();
   }
 };
 protected Dialog onCreateDialog(int id) 
 {
    switch(id)
    {
      case DATE_DIALOG_ID:
                   return new DatePickerDialog(this,datelistener , y, mo, d);

      case TIME_DIALOG_ID:
                  return new TimePickerDialog(this,timelistener,h,m,false);
  }
  return null;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_rainbowbook, menu);
    return true;
}

}

现在我想知道如何将其放入其中，这样我就可以有一个从editTexts:传输信息的按钮

    EditText inputName;
    EditText inputRoom;
    public void onCreate1(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_rainbowbook);
        inputName = (EditText) findViewById(R.id.editText1);
        inputRoom = (EditText) findViewById(R.id.editText2);
        Button btnNextScreen = (Button) findViewById(R.id.button3);
        //Listening to button event
        btnNextScreen.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                //Starting a new Intent
                Intent nextScreen = new Intent(getApplicationContext(), BookingsActivity.class);
                //Sending data to another Activity
                nextScreen.putExtra("name", inputName.getText().toString());
                nextScreen.putExtra("room", inputRoom.getText().toString());
                Log.e("n", inputName.getText()+"."+ inputRoom.getText());
                startActivity(nextScreen);
            }
        });
    }

我似乎想不通，希望有人能帮我。谢谢。

Answer 1

 maybe this in your BookingActivity
 Bundle b = i.getExtras();
 String name = b.getString("name", "default name");
 String room = b.getString("room", "default room");

编辑：此外，使用startActivityForResult（）启动BookingActivity，这样您就可以在完成后从中取回数据。

编辑：startActivityForResult的示例可以找到如何从TabHost活动返回结果（startActivityForResult）？和http://android.rahulblogs.com/android-startactivityforresult-example/
