DrawerLayout предотвращает сенсорные события в EditText

Попробуйте drawerlayout.requestDisallowInterceptTouchEvent(true) в своем oncreate

Установите как редактировать текст, так и текстовое представление явно как интерактивные.. затем реализовать что-то подобное для представления списка

    /******************************Listener for Drawer***************/
private class DrawerItemClickListener implements ListView.OnItemClickListener
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        //your code here based on posotion

    }   
}

вы можете установить слушателя, используя что-то вроде этого

     DrawerList.setOnItemClickListener(new DrawerItemClickListener());

я обнаружил аналогичную проблему, у меня есть обновление sdk и особенно дополнительная папка, и все работает нормально.

Я проверил ваш код, и он отлично работает на моем устройстве.

Спасибо надеюсь поможет.

я сделал что-то вроде этого,

я обновил ваш код.

edittext теперь может принимать фокус

создать main.xml

<android.support.v4.widget.DrawerLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/drawer_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <FrameLayout
                android:background="@drawable/background"
                android:id="@+id/main_content"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
    <-- my main layouts here -->
    </FrameLayout>

  <FrameLayout
        android:id="@+id/navigation_frame"
        android:layout_width="280dp"
        android:layout_height="match_parent"
        android:layout_gravity="start" />

    </android.support.v4.widget.DrawerLayout>

создать файл navigation.xml

<LinearLayout

        android:id="@+id/left_linear"
        android:layout_width="fill_parent"

        <LinearLayout
            android:layout_width="fill_parent"

            android:layout_gravity="center"
            android:clickable="true"

                android:src="@android:drawable/ic_menu_search" />
        </LinearLayout>

            <ListView android:id="@+id/left_drawer"

                android:divider="@android:color/transparent"
                android:dividerHeight="0dp"
                android:background="#111"/>
            </LinearLayout>

//создать активность как

public class HomeActivity extends actionbaractivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        // add menu to navigation drawer
        addMenu();
    }


    private void addMenu()
    {

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();
        fragmentTransaction.replace(R.id.navigation_frame,
                new NavigationFragment());
        fragmentTransaction.commit();
    }
}

// создаем новый класс фрагмента, который добавляет меню в макет ящика

public class NavigationFragment extends Fragment 
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    {
        View view=inflater.inflate(R.layout.navigation_view, null);
               return view;
    }
}

// у меня работает..

Try to add your Edittext and textview of the layout in below lines

    android:focusableInTouchMode="true"
    android:focusable="true"
  or 
 oncreate methos you use requestfocus(your element id);

thank you.
