BaseActivity para la navegación

Estoy construyendo una actividad básica para la navegación y deseo algo flexible así que la actividad dicta a la actividad baja qué disposición a inflar.

Tengo lo siguiente

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 } 

A continuación, el diseño se pasa de la actividad como continuación

 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 } } 

¿Hay una mejor manera de lograr esto? Tal vez la configuración de un diseño de base con un marco de contenido e inflar en eso?

Cualquier sugerencia sera apreciada.

Puede seguir BaseActivity desde la aplicación Google IO. Simplemente anula setContentView y no necesita setLayout

Aquí está mi 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); } } 

Puede consultar mi siguiente código, preste atención a addContentView en mi actividad base (aquí lo llamo NavigationDrawerActivity )

Actividad básica:

 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); } } 

Luego en otras actividades, por ejemplo, MainActivity:

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

¡Espero que esto ayude!

Realizo algunos cambios en la clase BaseActivity utilizando el método de inflado de la baseactividad y la reutilización, puedes usar la siguiente clase para extenderla solo a cualquiera de tu clase de actividad.

Esta es mi base_activity.xml,

setContentView anular setContentView en su BaseActivity e inicializar todo después de la super llamada o mover todas las cosas relacionadas con DrawerLayout a un método protected y llamar desde cada hijos de BaseActivity , después de llamar a setContentView . Creo que el primero debe ser sencillo, a partir de lo que publicó, se puede evitar para anular onCreate en el BaseActivity
