Question

我想在oncreate() Main android:noHistory="true"方法中启动MainAcitivty后清除HistoryStack。

由于某些问题，我无法使用finish()，因为它会导致我的gPlus登录出现问题，但出于类似原因也无法使用FLAG_ACTIVITY_NO_HISTORY SELECT dbo_job.item, sub2.item AS NewCheck FROM dbo_job LEFT JOIN ( SELECT dbo_job.item FROM dbo_job WHERE dbo_job.job_date<=#7/13/2015# AND dbo_job.job_date>=#6/22/2015# GROUP BY dbo_job.item) AS sub ON sub.item=dbo_job.item LEFT JOIN ( SELECT dbo_job.item FROM dbo_job WHERE dbo_job.job_date<#7/13/2015# GROUP BY dbo_job.item) AS sub2 ON sub2.item=dbo_job.item WHERE dbo_job.job_date=#7/20/2015# AND sub.item IS NULL GROUP BY dbo_job.item, sub2.item。

我只希望在特殊情况下删除它，当它在Main内部时，否则它应该在History堆栈中。

一旦进入Main，所有历史记录堆栈都应该清除，并且在按下后应用程序应该退出。是否有可能，如果是，请解释。

Answer 1

对于没有最近活动，活动在欲望活动中使用android:excludeFromRecents="true"。

Answer 2

您可以在要完成的所有活动中添加BroadcastReceiver。

public class MyActivity extends Activity {
private FinishReceiver finishReceiver;
private static final String ACTION_FINISH =
        "com.mypackage.MyActivity.ACTION_FINISH";

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

    finishReceiver = new FinishReceiver();
    registerReceiver(finishReceiver, new IntentFilter(ACTION_FINISH));
}

@Override
protected void onDestroy() {
    super.onDestroy();

    unregisterReceiver(finishReceiver);
}

private final class FinishReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION_FINISH))
            finish();
    }
}
}

您可以通过调用

关闭这些活动

sendBroadcast(new Intent(ACTION_FINISH));
