Android/クラスモジュール化

クラス呼び出しサンプル

• info/nonip/Test1/Test1Activity.java

package info.nonip.Test1;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class Test1Activity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    Animal animal = new Animal();
    Log.i("test", animal.getName());
    }
}

• info/nonip/Test1/Animal.Java

package info.nonip.Test1;
public class Animal {
  public String getName() {
    return "動物";
  }
}

継承を使う

• TestActivity.java

Cat cat = new Cat(); Log.i("test", cat.getName());

• AbstractAnimal.java

package info.nonip.Test1;
public abstract class AbstratAnimal {
  public String getName() {
    return "動物";
  }
}

• Cat.java

package info.nonip.Test1;
public class Cat extends AbstratAnimal {
  public String getName() {
    return "ネコ";
  }
}

インターフェースを使う

• AbstractAnimal.java

package info.nonip.Test1;
public abstract class AbstratAnimal implements InterfaceAnimal {
  public String getName() {
    return "動物";
  }
}

• InterfaceAnimal.java

package info.nonip.Test1;
public interface InterfaceAnimal {
  public String getName();
}
