[Jython] MACでjythonをインストールしてみた。

MACでjythonをインストールしてみた。

jythonは「http://www.jython.org/」でダウンロードする。
今回ダウンロードしたファイルは「jython_installer-2.5.1.jar」

インストール開始。


$ java -jar jython_installer-2.5.1.jar

実行するとGUIインストール画面が出る。
ちなみにコンソールモードは


$ java -jar jython_installer-2.5.1.jar --console

インストールPATHを「/usr/local/jython2.5.1」にしたかったので

先に「/usr/local/jython2.5.1」を作って指定した。

これで完了。

軽くにテストしてみる。

[Android] Custom Component - DateTimePicker

DatePickerとTimePickerを利用したDateTimePickerというのを作ってみた。

作った理由は何故かDatePickerとTimePickerは存在するのに、
日付と時間を両方設定できるコンポーネントが見つからないからだ。実はあるのか？
別にCustomコンポーネントの作り方の勉強にもなると思ったので作ってみよう。

レイアウト [res/layout/datetime_picker.xml]


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content" android:layout_height="wrap_content"
 android:orientation="vertical" android:gravity="center">
 <DatePicker android:id="@+id/_babukuma_datetime_picker_date_picker"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></DatePicker>
 <CheckBox android:id="@+id/_babukuma_datetime_picker_enable_time"
  android:layout_width="wrap_content" android:layout_height="wrap_content"
  android:text="enable Time"></CheckBox>
 <TimePicker android:id="@+id/_babukuma_datetime_picker_time_picker"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></TimePicker>
</LinearLayout>

次は必要かと思われるアトリビュートを定義（とりあえずはこれぐらいかな） [res/values/attrs.xml]


<?xml version="1.0" encoding="utf-8"?>
<resources>
 <declare-styleable name="DataTimePicker">
  <attr name="enableTime" format="boolean" />
  <attr name="year" format="integer" />
  <attr name="month" format="integer" />
  <attr name="day" format="integer" />
  <attr name="hour" format="integer" />
  <attr name="minute" format="integer" />
 </declare-styleable>
</resources>

次はDateTimePickerのスース [DateTimePicker.java]
やってるのはほぼDatePickerとTimePickerの機能をラッピングするだけ。
それと下段のTimePickerをCheckBoxで表示/非表示させただけ。

次回はDateTimePickerDialogを作ってみる。

[Android] Custom Component - DateTimePicker

DatePicker와 TimePicker를 이용하여 간단하게 만들어본 DateTimePicker

DatePicker와 TimePicker는 존재하지만, 왜인지 날짜와 시간을 한번에 설정할 수 있는 컨포넌트가 안보인다.
그래서 간단하게 만들어봤다.

우선 레이아웃 구성 [res/layout/datetime_picker.xml]


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content" android:layout_height="wrap_content"
 android:orientation="vertical" android:gravity="center">
 <DatePicker android:id="@+id/_babukuma_datetime_picker_date_picker"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></DatePicker>
 <CheckBox android:id="@+id/_babukuma_datetime_picker_enable_time"
  android:layout_width="wrap_content" android:layout_height="wrap_content"
  android:text="enable Time"></CheckBox>
 <TimePicker android:id="@+id/_babukuma_datetime_picker_time_picker"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></TimePicker>
</LinearLayout>

다음은 몇가지 필요할 것 같은 Attribute를 정의 [res/values/attrs.xml]


<?xml version="1.0" encoding="utf-8"?>
<resources>
 <declare-styleable name="DataTimePicker">
  <attr name="enableTime" format="boolean" />
  <attr name="year" format="integer" />
  <attr name="month" format="integer" />
  <attr name="day" format="integer" />
  <attr name="hour" format="integer" />
  <attr name="minute" format="integer" />
 </declare-styleable>
</resources>

다음으로는 DateTimePicker의 소스다. [DateTimePicker.java]
대부분이 기존의 DatePicker와 TimePicker가 가지고 있는 메소드를 그대로 사용하도록 했고,
단지 하단의 TimePicker를 CheckBox를 이용해서 활성화/비활성화 시킨 것 뿐이다.

  return timePicker.getCurrentHour();
 }

 public int getCurrentMinute() {
  return timePicker.getCurrentMinute();
 }

 public boolean enableTime() {
  return enableTimeCheckBox.isChecked();
 }
}

나중에 좀더 속성을 추가하고, 살을 더 붙이면 쓸만할 것 같긴한데,
우선은 이것으로 대충 완성. 일단은 쓸 수는 있어보이니까.

다음은 간단하게 테스트.

테스트용 레이아웃 [res/layout/datetime_picker_test.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="wrap_content"
 android:orientation="vertical">
 <TextView android:id="@+id/datetime_picker_activity_text_view"
  android:layout_width="fill_parent" android:layout_height="48dip"
  android:textColor="#000000" android:background="#CCCCCC"
  android:gravity="center" android:text="time"></TextView>
 <com.babukuma.android.view.DateTimePicker
  android:layout_width="wrap_content" android:layout_height="wrap_content"
  year="2010" month="1" day="29" hour="14" minute="1" startYear="2000"
  android:id="@+id/datetime_picker_activity_datetime_picker">
 </com.babukuma.android.view.DateTimePicker>
</LinearLayout>

그리고 테스트용 소스 [DateTimePickerActivity.java]


package com.babukuma.android.test;

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

import com.babukuma.android.view.DateTimePicker;
import com.babukuma.android.view.DateTimePicker.OnDateTimeChangedListener;

public class DateTimePickerActivity extends Activity {
 final DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm");

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.datetime_picker_test);

  final TextView timeView = (TextView) findViewById(R.id.datetime_picker_activity_text_view);
  final DateTimePicker dateTimePicker = (DateTimePicker) findViewById(R.id.datetime_picker_activity_datetime_picker);
  dateTimePicker
    .setOnDateTimeChangedListener(new OnDateTimeChangedListener() {
     @Override
     public void onDateTimeChanged(DateTimePicker view,
       int year, int monthOfYear, int dayOfMonth,
       int hourOfDay, int minute) {
      Calendar calendar = Calendar.getInstance();
      calendar.set(year, monthOfYear, dayOfMonth, hourOfDay,
        minute);
      timeView.setText(dateFormat.format(calendar.getTime()));
     }
    });

  Calendar calendar = Calendar.getInstance();
  calendar.set(dateTimePicker.getYear(), dateTimePicker.getMonth(),
    dateTimePicker.getDayOfMonth(),
    dateTimePicker.getCurrentHour(), dateTimePicker
      .getCurrentMinute());
  timeView.setText(dateFormat.format(calendar.getTime()));
 }
}

다음에는 DateTimePickerDialog를 만들어봐야겠다.

[Android] ListView에 Button 추가

Android에서 빈번하게 사용하는 ListView에 Button을 추가하는 방법.

우선, TextView와 Button을 가지고 있는 레이아웃(리스트의 한행)을 작성한다.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="fill_parent"
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_height="wrap_content">
 <TextView android:id="@+id/list_with_button_text"
  android:layout_height="48dp" android:layout_width="fill_parent"
  android:layout_marginRight="80dp"></TextView>
 <Button android:id="@+id/list_with_button_button"
  android:layout_alignParentRight="true" android:layout_height="48dp"
  android:layout_width="80dp"></Button>
</RelativeLayout>

다음은 BaseAdapter를 상속받아서 Adapter를 작성한다.

package com.babukuma.android.test;

import static com.babukuma.android.test.Main.LOG_TAG;
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

public class ListViewWithButton extends ListActivity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  setListAdapter(new ListAdapterWithButton<String>(this, getResources()
    .getStringArray(R.array.list_test_menus)));
 }

 class ListAdapterWithButton<T> extends BaseAdapter {
  private final LayoutInflater mInflater;
  private final T[] array;

  public ListAdapterWithButton(final Context context, final T[] array) {
   this.mInflater = LayoutInflater.from(context);
   this.array = array;
  }

  @Override
  public int getCount() {
   return array.length;
  }

  @Override
  public T getItem(int position) {
   return array[position];
  }

  @Override
  public long getItemId(int position) {
   return position;
  }

  class ViewHolder {
   TextView label;
   Button button;
  }

  @Override
  public View getView(final int position, View convertView,
    ViewGroup parent) {
   ViewHolder holder;

   if (convertView == null) {
    convertView = mInflater
      .inflate(R.layout.list_with_button, null);

    // Creates a ViewHolder and store references to the two children
    // views
    // we want to bind data to.
    holder = new ViewHolder();
    holder.label = (TextView) convertView
      .findViewById(R.id.list_with_button_text);
    holder.label.setOnClickListener(new OnClickListener() {
     @Override
     public void onClick(View v) {
      Log.d(LOG_TAG, "label click position=" + position);
     }
    });
    holder.button = (Button) convertView
      .findViewById(R.id.list_with_button_button);
    holder.button.setOnClickListener(new OnClickListener() {

     @Override
     public void onClick(View v) {
      Log.d(LOG_TAG, "button click position=" + position);
     }
    });

    holder.label.setText(array[position].toString());
    holder.button.setText(array[position].toString());

    convertView.setTag(holder);
   } else {
    holder = (ViewHolder) convertView.getTag();
   }

   return convertView;
  }

 }
}

완성. 선택됐을 경우에 배경색을 바꾸는 건 필요하다면 수동으로 추가해야 할 듯.

[Android] ListViewにButtonを追加する。

Androidでよく使ってるListViewにButtonを追加する方法。

まず、TextViewとButtonを持つ行レイアウトを作る。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="fill_parent"
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_height="wrap_content">
 <TextView android:id="@+id/list_with_button_text"
  android:layout_height="48dp" android:layout_width="fill_parent"
  android:layout_marginRight="80dp"></TextView>
 <Button android:id="@+id/list_with_button_button"
  android:layout_alignParentRight="true" android:layout_height="48dp"
  android:layout_width="80dp"></Button>
</RelativeLayout>

次はAdapterをカスタマイズする。

package com.babukuma.android.test;

import static com.babukuma.android.test.Main.LOG_TAG;
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

public class ListViewWithButton extends ListActivity {
 @Override

これで完了。

ANTでSVNを使用。

ANTで拡張タスク「<svn>」を使ってみる。

必要なライブラリは「svnant」。
http://subclipse.tigris.org/svnant.html サイトでダウンロードする。

まず、「<svn>」タスクを使って「export」のテスト結果。

$ ant -lib ./lib -buildfile svn_export.xml
Buildfile: svn_export.xml

main:
     [echo] called target main
    [input] remote repository url=
{リポジトリURL}
    [input] local export dir=
{ローカル保存先}
    [input] svn userid=
{svnのユーザID}
    [input] svn password=
{svnのパスワード}

export:
     [echo] SVN エクスポート。。。
      [svn] <Export> started ...
      [svn] <Export> finished.

BUILD SUCCESSFUL
Total time: 23 seconds

実行するときに「svnant」ライブラリが格納されてるPATHを知らせる為、
「-lib」オプションを付けるのが重要！

ソース(svn_export.xml)は

<?xml version="1.0" encoding="UTF-8"?>
<project default="main" basedir=".">
    <typedef resource="org/tigris/subversion/svnant/svnantlib.xml" />

    <target name="export">
        <echo>SVN エクスポート。。。</echo>
        <svn username="${svn.user}" password="${svn.password}">

他のタスクや使い方は
http://subclipse.tigris.org/svnant/svn.html
を参照。

ANTでif文とfor文を使用。

ANTで拡張タスク「<if>」、「<for>」を使ってみる。

必要なライブラリは「ant-contrib」。
今回試してみたバージョンは「1.0b3」
ant-contrib サイトで「ant-contrib-1.0b3」をダウンロードする。

まず、「<if>」のテスト結果。

$ ant -buildfile if_test.xml
Buildfile: if_test.xml

main:
     [echo] called target main
     [echo] hello babukuma!
     [echo] abcd else...

使ってみると結構便利だと俺は勝手に思った。（hiro_nemuさんには他のスクリプトでいいんじゃってつこまれたけど。）
