FLAG_ACTIVITY_XXX

add to dictionary 메뉴를 통해 Userdictionary로 startActivity를 할 때,

GB와 달리 ICS에선 이 Activity도 Recent App으로 나타난다는 점이 문제가 된다.

 

이를 막기 위해 다음 시도를 하는데...

if (suggestionInfo.suggestionIndex == ADD_TO_DICTIONARY) {

                Intent intent = new Intent(Settings.ACTION_USER_DICTIONARY_INSERT);

                intent.putExtra("word", originalText);

                intent.putExtra("locale", getTextServicesLocale().toString());

                intent.setFlags(intent.getFlags() | Intent.FLAG_ACTIVITY_NEW_TASK);

                getContext().startActivity(intent);

                // There is no way to know if the word was indeed added. Re-check.

                // TODO The ExtractEditText should remove the span in the original text instead

                editable.removeSpan(suggestionInfo.suggestionSpan);

                updateSpellCheckSpans(spanStart, spanEnd, false);

            } else {

위 빨간 글씨 부분을 FLAG_ACTIVITY_CLEAR_TOP로 변경하는 것이다.

 

/**

     * If set, and the activity being launched is already running in the

     * current task, then instead of launching a new instance of that activity,

     * all of the other activities on top of it will be closed and this Intent

     * will be delivered to the (now on top) old activity as a new Intent.

     *

     * <p>For example, consider a task consisting of the activities: A, B, C, D.

     * If D calls startActivity() with an Intent that resolves to the component

     * of activity B, then C and D will be finished and B receive the given

     * Intent, resulting in the stack now being: A, B.

     *

     * <p>The currently running instance of activity B in the above example will

     * either receive the new intent you are starting here in its

     * onNewIntent() method, or be itself finished and restarted with the

     * new intent.  If it has declared its launch mode to be "multiple" (the

     * default) and you have not set {@link #FLAG_ACTIVITY_SINGLE_TOP} in

     * the same intent, then it will be finished and re-created; for all other

     * launch modes or if {@link #FLAG_ACTIVITY_SINGLE_TOP} is set then this

     * Intent will be delivered to the current instance's onNewIntent().

     *

     * <p>This launch mode can also be used to good effect in conjunction with

     * {@link #FLAG_ACTIVITY_NEW_TASK}: if used to start the root activity

     * of a task, it will bring any currently running instance of that task

     * to the foreground, and then clear it to its root state.  This is

     * especially useful, for example, when launching an activity from the

     * notification manager.

     *

     * <p>See

     * <a href="{@docRoot}guide/topics/fundamentals/tasks-and-back-stack.html">Tasks and Back

     * Stack</a> for more information about tasks.

근데 내 생각엔 다음 flag가 더 적절하지 않나 싶다.

/**

     * If set, the new activity is not kept in the history stack.  As soon as

     * the user navigates away from it, the activity is finished.  This may also

     * be set with the {@link android.R.styleable#AndroidManifestActivity_noHistory

     * noHistory} attribute.

한번 검토해 보길.
