android *** Layout 10 DatePicker && TimePicker

照例贴地址，http://android-doc.com/guide/topics/ui/controls/pickers.html

主要还是监听器的设置。

xml文件如下

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android1="http://schemas.android.com/apk/res/android"
android:id="@+id/relative"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >

<DatePicker
android1:id="@+id/datePicker1"
android1:layout_width="wrap_content"
android1:layout_height="wrap_content"
android1:layout_alignParentLeft="true"
android1:layout_alignParentTop="true" />

</RelativeLayout>

java如下

package com.example.tree;

import android.support.v7.app.ActionBarActivity;
import android.util.Log;

import java.util.ArrayList;
import java.util.Calendar;
import java.util.List;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.*;
import android.view.View.OnClickListener;
import android.view.View.OnKeyListener;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends ActionBarActivity implements OnClickListener{

private DatePicker date;
private int year,monthofyear,dayofmonth;
private final String TAG="MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "-onCreate-->>");
//初始化日期
Calendar cal=Calendar.getInstance();
year=cal.get(Calendar.YEAR);
monthofyear=cal.get(Calendar.MONTH)+1;
dayofmonth=cal.get(Calendar.DAY_OF_MONTH);

date=(DatePicker)this.findViewById(R.id.datePicker1);
date.init(year,monthofyear,dayofmonth, new DatePicker.OnDateChangedListener() {

@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// TODO Auto-generated method stub
String date=year+" year "+monthofyear+" month "+dayofmonth+" day ";
Toast.makeText(MainActivity.this, "-->>"+date, 1).show();
}
});

}

protected void onStart(){
super.onStart();
Log.i(TAG, "-onStart-->>");
}

protected void onRestart(){
super.onRestart();
Log.i(TAG, "-onRestart-->>");
}

protected void onResume(){
super.onResume();
Log.i(TAG, "-onResume-->>");
}

protected void onPause(){
super.onPause();
Log.i(TAG, "-onPause-->>");
}

protected void onStop(){
super.onStop();
Log.i(TAG, "-onStop-->>");
}

protected void onDestroy(){
super.onDestroy();
Log.i(TAG, "-onDestroy-->>");
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
}

TimePicker一样，只是设置监听器的问题而已

xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android1="http://schemas.android.com/apk/res/android"
android:id="@+id/relative"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >

<TimePicker
android1:id="@+id/timePicker1"
android1:layout_width="wrap_content"
android1:layout_height="wrap_content"
android1:layout_alignParentLeft="true"
android1:layout_alignParentTop="true" />
