android中兩種銷毀activity的方式

李國帥，編于年後

新年好，今天頭天上班，繼續整理，把以前的東西提取成一個個小檔案。

public class BaseActivity extends Activity {

    private BroadcastReceiver recvExit;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        MyApplication.getActivityList().addActivity(this);//方式1 以前的方式--記錄和周遊


        recvExit = new BroadcastReceiver() {//方式2 新的方式-廣播
            @Override
            public void onReceive(Context context, Intent intent) {
                if (intent.getAction().equals("EXIT_APP")){
                    finish();
                }
            }
        };

        IntentFilter filter = new IntentFilter();
        filter.addAction("EXIT_APP");

        registerReceiver(recvExit, filter);
    }

    @Override
    protected void onDestroy() {
        //MyLog.i(TAG, " destroy!");
        MyApplication.getActivityList().removeActivity(this);//方式1

        try {
            unregisterReceiver(recvExit);//方式2
        }catch (Exception e){
        }

        super.onDestroy(); // Always call the superclass
    }
}

銷毀的時候調用函數
    public void finishAll() { //方式1
        for (Activity activity : activityList) {
            if (activity != null) {
                activity.finish();
            }
        }
    }
    public void finishAll() {//方式2
        Intent intent = new Intent("EXIT_APP");
        MyApplication.getAppContext().sendBroadcast(intent);
    }
