Android Search Activity in Single Activity

I am trying to make my app consist a SINGLE activity. This activity should be able to create a search and also receive a search. Unfortunately, I am getting a “double” search bar in my SearchView when I click on the search button in the action bar. I mean that there is a search bar (dark– SearchView) that appears for a second in the action bar, and then a second one (white) appears OVER the action bar. Any help? What am I doing wrong?
Sorry, this search thing is all new and confusing to me.

MainActivity (the only activity):

  • Change the Right Margin of a View Programmatically?
  • How to dismiss keyboard in Android SearchView?
  • Detect soft navigation bar availability in android device progmatically?
  • cannot find keytool on a mac

    main.xml (the menu xml):

    From Setting Up the Search Interface in the Android Documentation:

    In your searchable activity, handle the ACTION_SEARCH intent by
    checking for it in your onCreate() method.

    Note: If your searchable activity launches in single top mode
    (android:launchMode=”singleTop”), also handle the ACTION_SEARCH intent
    in the onNewIntent() method. In single top mode, only one instance of
    your activity is created and subsequent calls to start your activity
    do not create a new activity on the stack. This launch mode is useful
    so users can perform searches from the same activity without creating
    a new activity instance every time.

    Please try to add the following attribute to your <activity> in your manifest file:

    android:launchMode="singleTop"
    

    This will make the same activity to receive the search intent.

    More info here: http://developer.android.com/guide/topics/manifest/activity-element.html

    Also, you have <intent-filter> declared twice, you should merge it into one element.

    Okay, the problem had to do with calling onSearchRequested() in onOptionsItemSelected(MenuItem item). That is redundant when I have a SearchView and should only be called on older platforms.

    So, I created a separate menu item for devices under Honeycomb. It is removed at runtime for newer devices. The SearchView is removed at runtime for older devices.

    See updated code below:

    @SuppressLint("NewApi")
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        mMenu = menu;
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
    
    
    
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            //remove old
            menu.removeItem(R.id.search_old);
            SearchManager searchManager =
                    (SearchManager) getSystemService(Context.SEARCH_SERVICE);
            SearchView searchView =
                    (SearchView) menu.findItem(R.id.search).getActionView();
            searchView.setSearchableInfo(
                    searchManager.getSearchableInfo(getComponentName()));
            searchView.setIconifiedByDefault(false);
        } else{
            //remove new
            menu.removeItem(R.id.search);
        }
    
    
        return true;
    }
    
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.search_old:
                onSearchRequested();
                return true;
            default:
                return false;
        }
    }
    
    @SuppressLint("NewApi")
    @Override
    public boolean onSearchRequested() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            MenuItem mi = mMenu.findItem(R.id.search);
            if(mi.isActionViewExpanded()){
                mi.collapseActionView();
            } else{
                mi.expandActionView();
            }
        } else{
            //onOptionsItemSelected(mMenu.findItem(R.id.search));
        }
        return super.onSearchRequested();
    }
