1、申明一个监听器，使用匿名内部类：
DatePickerDialog.OnDateSetListener onDateSetListener = new DatePickerDialog.
OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
System.out.println(year + ":" + monthOfYear + ":" + dayOfMonth);
}
};
2、复写Activity类的protected Dialog onCreateDialog(int id)方法
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_PICKER_ID:
return new DatePickerDialog(this, onDateSetListener, 2011, 8, 26);
}
return null;
}
3、在需要显示日期的时候调用showDialog(DATE_PICKER_ID)方法
例子：
main.xml文件
< xml version="1.0" encoding="utf-8" >
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/textView"
/>
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/button"
android:text="显示日期"
/>
java代码：
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
public class DatePickerActivity extends Activity {
private static final int DATE_PICKER_ID = 1;
private Button button = null;
private TextView tv = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) findViewById(R.id.textView);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(DATE_PICKER_ID);//此方法用于显示DatePickerDialog
}
});
}
//监听器，监听用户点下DatePickerDialog的set按钮时，所设置的年月日
private DatePickerDialog.OnDateSetListener onDateSetListener = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
tv.setText(year + ":" + monthOfYear + ":" + dayOfMonth);
}
};
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_PICKER_ID:
return new DatePickerDialog(this, onDateSetListener, 2011, 8, 26);
}
return null;
}
}
