How to add a functional search bar to a navigation drawer?

问题

I am developing a wallpaper app that loads it's images from Picasa I have a Navigation drawer that retrieves it's items name from the Picasa album names (I am using the source code of this tutorial Link ), so I want to add a search bar that filters the items in the navigation drawer, any idea on how I could accomplish this?

It might be a little late. But may help others.

1. Add an EditText to navigation Drawer.(activity_main.xml)

   <EditText
      android:id="@+id/inputSearch"
      android:layout_width="match_parent"
      android:layout_height="40dp"
      android:layout_margin="10dp"
      android:hint="search" 
      android:padding="10dp"
      android:layout_marginTop="25dp"
      android:inputType="text" >
    </EditText>
   

2. add a TextWatcher to editText. (Add the following lines to onCreate)

      final EditText inputSearch = (EditText) findViewById(R.id.inputSearch);
   
       inputSearch.addTextChangedListener(new TextWatcher() {
   
       @Override
       public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
           // TODO Auto-generated method stub
           //You should use the adapter in NavigationDrawerFragment
           NavigationDrawerFragment.adapter.getFilter().filter(cs);
   
       }
   
       @Override
       public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
               int arg3) {
           // TODO Auto-generated method stub
   
       }
   
       @Override
       public void afterTextChanged(Editable arg0) {
           // TODO Auto-generated method stub
   
       }
   });
   

Hope this helps.

You can make your navigation drawer a Fragment that contains an ArrayAdapter, which implements Filterable. This adapter would contain list of your Picasa album names.

For the search box, a simple EditText would do the job. Register a TextWatcher that would listen to text change events and trigger Filter.filter() on a Filter returned from your ArrayAdapter.getFilter() with input text as query.
