「Androidの学習」Androidでアプリケーションを完全に終了するサンプルプログラム

方法1

applicationを使ってactivityを保存

public class TestApplication extends Application {
private LinkedList<Activity> sAllActivitys = new LinkedList<Activity>();

public void addActivity(Activity activity){
sAllActivitys.add(activity);
}

public void removeActivity(Activity activity){
sAllActivitys.remove(activity);
}

public LinkedList<Activity> getAllActivitys(){
return sAllActivitys;
}

}

方法2
package com.first.activity;
import java.util.LinkedList;
import android.app.Activity;
import android.os.Bundle;

public class BaseActivity extends Activity {

@オーバーライド
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
((MyApplication)getApplication()).addActivity(this);
}

@オーバーライド
protected void onDestroy() {
super.onDestroy();
((MyApplication)getApplication()).removeActivity(this);
}

protected void finishAll() {
LinkedList<Activity> sAllActivitys = ((MyApplication)getApplication()).getAllActivitys();
for(Activity activity : sAllActivitys) {
activity.finish();
}
sAllActivitys.clear();
}
protected void exit() {
finishAll();
System.exit(0);
}
}

Activity->BaseActivity、TabActivity->BaseActivity
