Android初学者：onDestroy

概述在覆盖活动的ondestroy时,我应该在super.onDestroy()之前或之后放置命令吗？ protected void onDestroy() { //option 1: callback before or ... super.onDestroy(); //option 2: callback after super.onDestroy();} (现在我 在覆盖活动的ondestroy时,我应该在super.onDestroy()之前或之后放置命令吗？

protected voID onDestroy() {    //option 1: callback before or ...    super.onDestroy();    //option 2: callback after super.onDestroy();}

(现在我担心：如果super.onDestroy太快,它将永远不会到达选项2.)

解决方法 当你调用super.onDestroy()时会发生这种情况.

Android Source

protected voID onDestroy() {    mCalled = true;    // dismiss any dialogs we are managing.    if (mManagedDialogs != null) {        final int numDialogs = mManagedDialogs.size();        for (int i = 0; i < numDialogs; i++) {            final Dialog dialog = mManagedDialogs.valueAt(i);            if (dialog.isShowing()) {                dialog.dismiss();            }        }    }    // also dismiss search dialog if showing    // Todo more generic than just this manager    SearchManager searchManager =         (SearchManager) getSystemService(Context.SEARCH_SERVICE);    searchManager.stopSearch();    // close any cursors we are managing.    int numCursors = mManagedCursors.size();    for (int i = 0; i < numCursors; i++) {        ManagedCursor c = mManagedCursors.get(i);        if (c != null) {            c.mCursor.close();        }    }}

从本质上讲,这意味着如果您在代码之前或之后调用它并不重要.
