Best Practice for Android Android Tablet

Question

I am looking for advice on a navigation pattern in android. In the current state of the application I'm working on, I have a navigation box and you can access some elements that basically change dynamically. When I click an item from the navigation box, I show a fragment. Therefore, at any time I want to return to the left menu. Now I need to move the "New Screen" activity from the image in the same template in order to have access to the box. The only way to get to the "New Screen" activity is one of the fragments.

Slice 0 has a list of items. By clicking on it, the "New Screen" opens. How should I approach this in order to have a box in this exercise? I do not want to have too much boiler code. It already has problems with android 4.2.2, I can only imagine how these changes will affect performance. I need to understand what is the best solution, do not have experience with this. All I want is ideas and maybe get some know-how on this template, so I don't cause memory leaks or duplicate code.

Thank you for your time.

Answer 1

1st would suggest creating a basic activity that will expand your ActionBarActivity.

2-activity_sliding_drawer main_container DrawerLayout: -

<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:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <FrameLayout
        android:layout_gravity="bottom"
        android:id="@+id/bottom_container"
        android:layout_height="wrap_content"
        android:visibility="gone"
        android:layout_width="match_parent"
        android:background="@color/white">
     </FrameLayout>
</FrameLayout>

<fragment
    android:id="@+id/slidingMenuFragment"
    android:name="om.ooredoo.fragments.SlidingMenuFragment"
    android:layout_width="@dimen/slidingmenu__parent_width"
    android:layout_height="fill_parent"
    android:layout_gravity="start" />

3- , 2 , , .. lockDrawerMenu() unlockDrawerMenu().

4 (AbstractActivity ): -

public abstract class AbstractActivity extends ActionBarActivity {
public DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;

    if (bSupportActionBar) {
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerLayout.setScrimColor(getResources().getColor(android.R.color.transparent));

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_navigation_drawer, //nav menu toggle icon
                R.string.drawer_open, // nav drawer open - description for accessibility
                R.string.drawer_close // nav drawer close - description for accessibility
        ) {

                invalidateOptionsMenu();
            }

                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);
