DatePickerDialog日期范围的控制

我用的是自定义dialog实现的，在DatePicker的onDateChangedListentr事件中实现范围的控制

代码如下：

public class MainActivity extends Activity {/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);final TextView text = (TextView) findViewById(R.id.text);LayoutInflater l = LayoutInflater.from(this);View v = l.inflate(R.layout.dialog, null);final DatePicker datePicker = (DatePicker) v.findViewById(R.id.datepicker);datePicker.init(2000, 1, 3, new OnDateChangedListener() {@Overridepublic void onDateChanged(DatePicker view, int year,int monthOfYear, int dayOfMonth) {if (isDateAfter(view)) {view.init(2000, 11, 30, this);}if (isDateBefore(view)) {view.init(1949, 11, 30, this);}}private boolean isDateAfter(DatePicker tempView) {if (tempView.getYear() > 2000) {return true;} elsereturn false;}private boolean isDateBefore(DatePicker tempView) {if (tempView.getYear() < 1921) {return true;} elsereturn false;}});Dialog dialog = new AlertDialog.Builder(this).setTitle(datePicker.getYear() + "年"+ (datePicker.getMonth() + 1) + "月"+ datePicker.getDayOfMonth() + "日").setView(v).setIcon(R.drawable.ic_dialog_time).setNeutralButton("设置", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {text.setText(datePicker.getYear() + "年"+ (datePicker.getMonth() + 1) + "月"+ datePicker.getDayOfMonth() + "日");}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {dialog.cancel();}}).create();dialog.show();}}

自定义的dialog.xml代码如下

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <DatePicker        android:id="@+id/datepicker"        android:layout_width="fill_parent"        android:layout_height="wrap_content" /></LinearLayout>

以上在3.0版本之前支持，在3.0版本以后请使用下面的方法

public void onClick(View v) {switch (answer.type) {case 1:// 日期类型DatePickerDialog dialog = new DatePickerDialog(ctx, this, 1980, 0,1);DatePicker datePicker = dialog.getDatePicker();datePicker.setMinDate(DateUtils.getInstance().format("1970-01-01").getTime());datePicker.setMaxDate(DateUtils.getInstance().format("2013-01-07").getTime());dialog.show();break;}}@Overridepublic void onDateSet(DatePicker view, int year, int monthOfYear,int dayOfMonth) {editText.setText(year + "年" + (monthOfYear + 1) + "月" + dayOfMonth+ "日");}
