1.日期选择控件
DatePickerDialog
代码：
1 btnChooseDate=(Button) findViewById(R.id.btnChooseDate);
2 btnChooseDate.setOnClickListener(new OnClickListener() {
3
4 @Override
5 public void onClick(View v) {
6 // TODO Auto-generated method stub
7 new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
8
9 @Override
10 public void onDateSet(DatePicker view, int year, int monthOfYear,
11 int dayOfMonth) {
12 // TODO Auto-generated method stub
13 String theDate=String.format("%d-%d-%d", year,monthOfYear+1,dayOfMonth);
14 btnChooseDate.setText(theDate);
15 }
16 }, 2015, 06, 16).show();
17 }
18 });
2.时间选择控件
TimePickerDialog
1 btnChooseTime=(Button) findViewById(R.id.btnChooseTime);
2 btnChooseTime.setOnClickListener(new OnClickListener() {
3
4 @Override
5 public void onClick(View v) {
6 // TODO Auto-generated method stub
7 new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
8
9 @Override
10 public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
11 // TODO Auto-generated method stub
12 String time=String.format("%d-%d", hourOfDay,minute);
13 btnChooseTime.setText(time);
14 }
15 }, 0, 0, true).show();
16 }
17 });
3.下拉选择列表
Spinner
1 spinner=(Spinner) findViewById(R.id.spinner1);
2 spinner.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,data));
3 spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
4
5 @Override
6 public void onItemSelected(AdapterView<?> parent, View view,
7 int position, long id) {
8 // TODO Auto-generated method stub
9 Toast.makeText(MainActivity.this, "点击了"+data[position], Toast.LENGTH_SHORT).show();
10 }
11
12 @Override
13 public void onNothingSelected(AdapterView<?> parent) {
14 // TODO Auto-generated method stub
15
16 }
17 });
4.单选按钮
RadioButton
注意：在XML文件中，必须使用RadioGroup控件，才可以使用RadioButton。
在JAVA文件中，判断RadioButton是否被点击，使用方法isChecked()。
