如何关闭我的应用程序的所有活动？ [英] How to close all the activities of my application?

问题描述

我有几个活动的应用程序，例如：

I've got an application with several activities, for example:

活动1 - >活动2 - >活动3 - >活动4

Activity 1 --> Activity 2 --> Activity 3 --> Activity 4

和我想从任何活动关闭所有的活动，回到家里的电话。

And I would like to close all the activities from any activity and go back at home phone.

推荐答案

可以实现通过使用 BroadcastReceivers ：

• 创建一个 BaseActivity 是这样的：

• Create a BaseActivity like this:

public class BaseActivity extends Activity {
    private KillReceiver mKillReceiver;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mKillReceiver = new KillReceiver();
        registerReceiver(mKillReceiver,
            IntentFilter.create("kill", "spartan!!!"));
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(mKillReceiver);
    }
    private final class KillReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            finish();
        }
    }
}

• 请你的活动延长了 BaseActivity 。
• 每当你想清除栈：

---

• Make your activities extend that BaseActivity.
• Whenever you want to clear the stack:

Intent intent = new Intent("kill");
intent.setType("spartan!!!");
sendBroadcast(intent);
