BaseActivity for Navigation

Question

I'm building a base activity for navigation and want something flexible so the Activity dictates to the Base Activity which layout to inflate.

I have the following

public abstract class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {

    private int mLayoutRes;

    protected void setLayout(int layoutRes) {
        mLayoutRes = layoutRes;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(mLayoutRes);

        // Layout implements toolbar
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        if (toolbar != null){
            setSupportActionBar(toolbar);
        }


        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        // The layout implements the nav
        if (drawer != null){
            ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
            drawer.setDrawerListener(toggle);
            toggle.syncState();

            NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
            navigationView.setNavigationItemSelectedListener(this);
        }

    }
// Other Nav code ommitted as its too verbose
}

Then the Layout is passed from the activity as folows

public class Home extends BaseActivity {

    private final String TAG = "Home";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.setLayout(R.layout.activity_home);
        super.onCreate(savedInstanceState);
        // Other Activity code
    }
}

Is there a better way to achieve this? Maybe setting a base layout with a content frame and inflating into that?

Any suggestions would be appreciated.

Answer 1

You can follow BaseActivity from Google IO application. Just override setContentView and you dont need setLayout

Here is my BaseActivity

package com.vtcmobile.kqviet.activity;


public class BaseActivity extends AppCompatActivity {

private Toolbar toolbar;

private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
private NavigationView navigationView;
protected Context mContext;


public NavigationView getNavigationView() {
    return navigationView;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mContext = BaseActivity.this;

}

@Override
public void setContentView(int layoutResID) {
    super.setContentView(layoutResID);
    initToolbar();
}

private void initToolbar() {
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

private void setUpNav() {
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerToggle = new ActionBarDrawerToggle(BaseActivity.this, drawerLayout, R.string.app_name, R.string.app_name);
    drawerLayout.setDrawerListener(drawerToggle);

    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(false);

    navigationView = (NavigationView) findViewById(R.id.navigation);


    // Setting Navigation View Item Selected Listener to handle the item
    // click of the navigation menu
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        public boolean onNavigationItemSelected(MenuItem menuItem) {

            // Checking if the item is in checked state or not, if not make
            // it in checked state
            if (menuItem.isChecked())
                menuItem.setChecked(false);
            else
                menuItem.setChecked(true);

            // Closing drawer on item click
            drawerLayout.closeDrawers();

            // Check to see which item was being clicked and perform
            // appropriate action
            Intent intent;
            switch (menuItem.getItemId()) {

            case R.id.xxxx:

                return true;



            }
            return false;
        }
    });

    // Setting the actionbarToggle to drawer layout

    // calling sync state is necessay or else your hamburger icon wont show
    // up
    drawerToggle.syncState();

}

@Override
public void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    setUpNav();

    drawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    drawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (drawerToggle.onOptionsItemSelected(item))
        return true;

    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}




 }

Answer 2

Here is my example of implementing to BaseActivity, I found I did it differently and it worked for me.

My Base Activity

public abstract class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}


public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.

    int id = item.getItemId();
    //swap this to a switch statement

    if (id == R.id.nav_newgame) {
        // Start new game

        Log.e("Base","new Game");
    } else if (id == R.id.nav_players) {

    } else if (id == R.id.nav_history) {

    } else if (id == R.id.nav_tools) {

    } else if (id == R.id.nav_share) {

    } else if (id == R.id.nav_about) {

    }

    DrawerLayout drawer = findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}
}

Any activity sharing the same Navigation Drawer

public class MainActivity extends BaseActivity
     {

         NavigationView navigationView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

navigationView = findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

}

Allowing one dynamic Nav Drawer in your base activity saving you the trouble of writing code over and over. Additionally you can override the Base Activity's Nav Drawer and make different results for different situations.

Answer 3

I make some changes in BaseActivity class using inflating layout of baseactivity and reuse, you can use following class for extend only into any one of your activity class.

import android.content.Context;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.FrameLayout;


public class BaseActivity extends AppCompatActivity {

public Toolbar toolbar;

public DrawerLayout drawerLayout;
public ActionBarDrawerToggle drawerToggle;
public NavigationView navigationView;
public Context mContext;
public NavigationView getNavigationView() {
    return navigationView;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mContext = BaseActivity.this;
    setContentView(R.layout.base_activity);

}

@Override
public void setContentView(int layoutResID) {
    DrawerLayout fullView = (DrawerLayout)getLayoutInflater().inflate(R.layout.base_activity, null);
    FrameLayout activityContainer = (FrameLayout) fullView.findViewById(R.id.activity_content);
    getLayoutInflater().inflate(layoutResID, activityContainer, true);
    super.setContentView(fullView);

    initToolbar();
}

private void initToolbar() {
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

private void setUpNav() {
    drawerLayout = (DrawerLayout) findViewById(R.id.activity_container);
    drawerToggle = new ActionBarDrawerToggle(BaseActivity.this, drawerLayout, R.string.app_name, R.string.app_name);
    drawerLayout.setDrawerListener(drawerToggle);

    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(false);

    navigationView = (NavigationView) findViewById(R.id.navigation);


    // Setting Navigation View Item Selected Listener to handle the item
    // click of the navigation menu
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        public boolean onNavigationItemSelected(MenuItem menuItem) {

            // Checking if the item is in checked state or not, if not make
            // it in checked state
            if (menuItem.isChecked())
                menuItem.setChecked(false);
            else
                menuItem.setChecked(true);

            // Closing drawer on item click
            drawerLayout.closeDrawers();

            // Check to see which item was being clicked and perform
            // appropriate action

            Intent intent;
            switch (menuItem.getItemId()) {
                case R.id.xxxx:
                    return true;
            }
            return false;
        }
    });

    // Setting the actionbarToggle to drawer layout

    // calling sync state is necessay or else your hamburger icon wont show
    // up
    drawerToggle.syncState();

}

@Override
public void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    setUpNav();

    drawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    drawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (drawerToggle.onOptionsItemSelected(item))
        return true;
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

This is my base_activity.xml,

<android.support.v4.widget.DrawerLayout
android:id="@+id/activity_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?actionBarSize"

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

</LinearLayout>
<android.support.design.widget.NavigationView
    android:id="@+id/navigation"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    />
</android.support.v4.widget.DrawerLayout>

Answer 5

You can refer to my following code, pay attention to addContentView in my base activity (here I name it NavigationDrawerActivity)

Base activity:

public class NavigationDrawerActivity extends AppCompatActivity {
    private DrawerLayout mDrawerLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_navigation_drawer);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, mDrawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close);
        mDrawerLayout.setDrawerListener(toggle);
        toggle.syncState();
    }
    /**
     * called in extending activities instead of setContentView...
     *
     * @param layoutId The content Layout Id of extending activities
     */
    public void addContentView(int layoutId) {
        LayoutInflater inflater = (LayoutInflater) this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(layoutId, null, false);
        mDrawerLayout.addView(contentView, 0);
    } 
}

Then in other activities, for example, MainActivity:

public class MainActivity extends NavigationDrawerActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.addContentView(R.layout.activity_main);
    }
}

Hope this helps!

Answer 6

you could either override setContentView in your BaseActivity and initialised everything after the super call or move all the DrawerLayout related stuff to a protected method and call it from each children of BaseActivity, after you call setContentView. I think the first should be straightforward an, from what you posted, you can avoid to override onCreate in the BaseActivity
