我正在为盲人社区开发一个Android应用程序 . 在我的应用程序中，我正在使用TTS /音频文件处理所有水龙头/触摸 . 它工作正常，但当用户打开TalkBack功能时，所有水龙头/触摸都被指定两次 . 首先，它将由TalkBack和我的内部机制决定 .

我能够检测到TalkBack是否已启用 .

public boolean accessibilityEnable(Context context) {
        boolean enable = false;
        Log.e("Reached before function", "yes");
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            try {
                AccessibilityManager manager = (AccessibilityManager) context.getSystemService(Context.ACCESSIBILITY_SERVICE);
                List<AccessibilityServiceInfo> serviceList = manager.getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_SPOKEN);
                Log.e("Reached before for loop", "yes");
                for (AccessibilityServiceInfo serviceInfo : serviceList) {
                    String name = serviceInfo.getSettingsActivityName();

                    if (!TextUtils.isEmpty(name) && name.equals(TALKBACK_SETTING_ACTIVITY_NAME)) {
                        enable = true;
                        Log.e("Reached after if loop", "yes");
                    }
                }
                Log.e("Reached after for loop", "yes");
            } catch (Exception e) {
                Log.e("Error", "Error aaya re");
            }
        }
        return enable;
    }

我想在我的应用程序处于活动状态时禁用对讲功能？
