所以我用 textViews、editTexts、日期对话框和时间对话框选择器创建了一个 Activity。加上一个按钮。
我用它来让日期/时间对话框工作：
公共类 RainbowBookActivity 扩展 Activity {
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;
}
}
现在我想知道如何把它放在那里，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);
}
});
}
我似乎无法弄清楚这一点，希望有人能帮助我。谢谢。
* 预订活动：
公共类 BookingsActivity 扩展 Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bookings);
TextView Name = (TextView) findViewById(R.id.textView2);
TextView Room = (TextView) findViewById(R.id.textView3);
Button btnClose = (Button) findViewById(R.id.btnClose);
Intent i = getIntent();
// Receiving the Data
String name = i.getStringExtra("name");
String room = i.getStringExtra("room");
Log.e("Bookings", name + "." + room);
// Displaying Received data
Name.setText(name);
Room.setText(room);
// Binding Click event to Button
btnClose.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Closing SecondScreen Activity
finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_bookings, menu);
return true;
}
}
