Android – 在销毁一个Activity后,isFinishing()的值是否仍然为true？

作为一个检查,我想使用isFinishing()(我不能使用isDestroyed(),因为我的最低API级别是16而不是17,isDestroyed()需要).

我可以在回调中使用isFinishing()来确保我的逻辑仅在Activity未被销毁时执行吗？

更具体地说,即使在调用onDestroy()之后,isFinishing()对于通过调用finish()销毁的Activity返回true？

我也看了一下源代码.这是isFinishing()：

public boolean isFinishing() {
        return mFinished;
    }

这里是finish(),其中变量设置为true：

/**
     * Finishes the current activity and specifies whether to remove the task associated with this
     * activity.
     */
    private void finish(boolean finishTask) {
        if (mParent == null) {
            int resultCode;
            Intent resultData;
            synchronized (this) {
                resultCode = mResultCode;
                resultData = mResultData;
            }
            if (false) Log.v(TAG,"Finishing self: token=" + mToken);
            try {
                if (resultData != null) {
                    resultData.preparetoLeaveProcess();
                }
                if (ActivityManagerNative.getDefault()
                        .finishActivity(mToken,resultCode,resultData,finishTask)) {
                    mFinished = true;
                }
            } catch (remoteexception e) {
                // Empty
            }
        } else {
            mParent.finishFromChild(this);
        }
    }

    /**
     * Call this when your activity is done and should be closed.  The
     * ActivityResult is propagated back to whoever launched you via
     * onActivityResult().
     */
    public void finish() {
        finish(false);
    }

我也看过Understanding of isFinishing()
但我似乎无法得出这个特定问题的答案.
