Android中实现日期时间选择器(DatePicker和TimePicker)

分享到:

利用Android应用框架提供的DatePicker(日期选择器)和TimePicker(时间选择器),实现日期时间选择器。

Dialog的Content布局文件(date_time_dialog.xml):

<?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"
android:padding="10dip" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="请选择日期"
android:textColor="#FFFFFF"
android:textSize="16sp" />
<DatePicker
android:id="@+id/date_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dip" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:singleLine="true"
android:text="请选择时间"
android:textColor="#FFFFFF"
android:textSize="16sp" />
<TimePicker
android:id="@+id/time_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dip" />
</LinearLayout>  

代码中的实现:

import java.util.Calendar;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.text.InputType;
import android.view.MotionEvent;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;

@Override

timePicker.setCurrentMinute(Calendar.MINUTE);
if (v.getId() == R.id.et_start_time) {
final int inType = etStartTime.getInputType();
etStartTime.setInputType(InputType.TYPE_NULL);
etStartTime.onTouchEvent(event);
etStartTime.setInputType(inType);
etStartTime.setSelection(etStartTime.getText().length());
builder.setTitle("选取起始时间");
builder.setPositiveButton("确  定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
StringBuffer sb = new StringBuffer();
sb.append(String.format("%d-%02d-%02d",
datePicker.getYear(),
datePicker.getMonth() + 1,
datePicker.getDayOfMonth()));
sb.append("  ");
sb.append(timePicker.getCurrentHour())
.append(":").append(timePicker.getCurrentMinute());
etStartTime.setText(sb);
etEndTime.requestFocus();
dialog.cancel();
}
});
} else if (v.getId() == R.id.et_end_time) {
int inType = etEndTime.getInputType();
etEndTime.setInputType(InputType.TYPE_NULL);
etEndTime.onTouchEvent(event);
etEndTime.setInputType(inType);
etEndTime.setSelection(etEndTime.getText().length());
builder.setTitle("选取结束时间");
builder.setPositiveButton("确  定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
StringBuffer sb = new StringBuffer();
sb.append(String.format("%d-%02d-%02d",
datePicker.getYear(),
datePicker.getMonth() + 1,
datePicker.getDayOfMonth()));
sb.append("  ");
sb.append(timePicker.getCurrentHour())
.append(":").append(timePicker.getCurrentMinute());
etEndTime.setText(sb);
dialog.cancel();
}
});
}
Dialog dialog = builder.create();
dialog.show();
}
return true;
}
}
