1.日期选择控件
DatePickerDialog
代码：
btnChooseDate=(Button) findViewById(R.id.btnChooseDate);
btnChooseDate.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
// TODO Auto-generated method stub
new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() { @Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
String theDate=String.format("%d-%d-%d", year,monthOfYear+1,dayOfMonth);
btnChooseDate.setText(theDate);
}
}, 2015, 06, 16).show();
}
});
2.时间选择控件
TimePickerDialog
btnChooseTime=(Button) findViewById(R.id.btnChooseTime);
btnChooseTime.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
// TODO Auto-generated method stub
new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() { @Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
String time=String.format("%d-%d", hourOfDay,minute);
btnChooseTime.setText(time);
}
}, 0, 0, true).show();
}
});
3.下拉选择列表
Spinner
spinner=(Spinner) findViewById(R.id.spinner1);
spinner.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,data));
spinner.setOnItemSelectedListener(new OnItemSelectedListener() { @Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "点击了"+data[position], Toast.LENGTH_SHORT).show();
} @Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub }
});
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()。
资源文件

JAVA
public class SingleChoose extends Activity {
private Button btnSubmit;
private RadioButton rdA;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.singlechoose);
btnSubmit=(Button) findViewById(R.id.btnSubmit);
rdA=(RadioButton) findViewById(R.id.rdA);
btnSubmit.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (rdA.isChecked()) {
Toast.makeText(SingleChoose.this, "答案是正确的", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(SingleChoose.this, "答案是错误的", Toast.LENGTH_SHORT).show();
}
}
});
}
}
5.多选
Checkbox

JAVA文件
public class MlutilChoose extends Activity implements OnCheckedChangeListener {
private CheckBox cb1,cb2,cb3,cb4;
private TextView showResult;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub

}
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
String str="你喜欢";
if (cb1.isChecked()) {
