重温ActivityCollector/BaseActivity随时退出和启动程序

ActivityCollector.java

package sunny.example.comeonbroadcastreceiverdo;

import android.app.Activity;
import java.util.List;
import java.util.ArrayList;
public class ActivityCollector {

	public static ListactivitiesList = new ArrayList();
	
	public static void addAtivity(Activity activity){
		activitiesList.add(activity);
	}
	public static void removeActivity(Activity activity){
		activitiesList.remove(activity);
	}
	public static void finishAll(){
		for(Activity activity:activitiesList){
			if(!activity.isFinishing()){
				activity.finish();
			}
		}
	}
}

BaseActivity.java

package sunny.example.comeonbroadcastreceiverdo;

import android.app.Activity;
import android.os.Bundle;
public class BaseActivity extends Activity{
	
	@Override
	protected void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		ActivityCollector.addAtivity(this);
	}
	@Override
	protected void onDestroy(){
		super.onDestroy();
		ActivityCollector.removeActivity(this);
	}

}

使用：

public class MainActivity extends BaseActivity{
protected void onCreate(Bundle savedInstanceState){
//BaseActivity中的onCreate()
super.onCreate(savedInstanceState);
........
 public void onClick(View view){
        ActivityCollector.finishAll();
}
.....
 }}
