How to open links from menu.xml using Fragments

How to open links from menu.xml using Fragments - android

I'm trying to add clickable items from menu.xml. It just not working, even Toast effect.
Layout is copy/paste below so you can check it.
There is my MainActivity.java when Im trying using id's.
MainActivity:
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
private SectionsPagerAdapter mSectionsPagerAdapter;
private static final String TAG = "MainActivity";
private ViewPager mViewPager;
ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.hamburgermenu);
DrawerLayout drawerLayout = findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close);
drawerLayout.addDrawerListener(actionBarDrawerToggle);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
tabLayout.getTabAt(0).setText("Home").setIcon(R.drawable.homeicon);
tabLayout.getTabAt(1).setText("Section 1").setIcon(R.drawable.explorer);
tabLayout.getTabAt(2).setText("Section 2").setIcon(R.drawable.innovator);
tabLayout.getTabAt(3).setText("Section 3").setIcon(R.drawable.collar);
tabLayout.setTabTextColors(getResources().getColorStateList(R.color.white));
}
#Override
public void onBackPressed() {
if(mWebView.canGoBack()) {
mWebView.goBack();
} else {
super.onBackPressed();
}
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.dashboard:
Intent intentExplorer = new Intent(this, Tab1Explorer.class);
startActivity(intentExplorer);
break;
case R.id.action_search:
//Display Toast for test
Log.d(TAG,"test");
Toast.makeText(this,"Search!", Toast.LENGTH_SHORT).show();
break;
case R.id.action_help:
Intent intentContact = new Intent(this,Tab3Collar.class);
startActivity(intentContact);
break;
case R.id.action_about:
Toast.makeText(this,"This is simple About Demo", Toast.LENGTH_LONG).show();
break;
default:
Toast.makeText(this,"XYZ", Toast.LENGTH_LONG).show();
return super.onOptionsItemSelected(item);
}
Toast.makeText(this,"XYZ", Toast.LENGTH_LONG).show();
return super.onOptionsItemSelected(item);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch(position) {
case 0:
Tab0Home tab0 = new Tab0Home();
return tab0;
case 1:
Tab1Section tab1 = new Tab1Section();
return tab1;
case 2:
Tab2Section tab2 = new Tab2Section();
return tab2;
case 3:
Tab3Section tab3 = new Tab3Section();
return tab3;
default:
return null;
}
}
#Override
public int getCount() {
// Show 4 total pages.
return 4 ;
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0:
return "Home";
case 1:
return "Section11";
case 2:
return "Section22";
case 3:
return "Section33";
}
return null;
}
}
}
menu_main.xml file looks fine. I have android:id's, icons, titles...
Activity_main.xml file looks:

I just want to display for example Toast when I click "Search" from Menu, but it not working. It just colapse hamburger menu without effect.
What should I change?

The navigation view does not use the onOptionsItemSelected method, instead you need to call navigationView.setOnNavigationItemSelectedListener

Android: Navigation Drawer with fragment and activities?

I'm trying to do navigation drawer with 2 fragment(later i will add), and 4 activities. In my code when i call activity and close. It's very laggy. I want it very smooth. Please see my code.
ublic class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private DrawerLayout drawerLayout;
private Toolbar toolbar;
private NavigationView navigationView;
FragmentManager fragmentManager;
private String[] pageTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pageTitle = new String[]{getString(R.string.frag_home),
getString(R.string.nav_introduction),};
drawerLayout = (DrawerLayout)findViewById(R.id.drawerLayout);
toolbar = (Toolbar)findViewById(R.id.toolbar);
toolbar.setTitle(pageTitle[0]);
setSupportActionBar(toolbar);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
R.string.drawer_open, R.string.drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
navigationView = (NavigationView)findViewById(R.id.nav_view);
// assert navigationView != null: Log.wtf("haha", "OMG");
assert navigationView != null;
navigationView.setNavigationItemSelectedListener(this);
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, new Fragment_home()).commit();
}
#Override
public boolean onNavigationItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.nav_introduction: {
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, new Fragment_Introduction()).commit();
}
break;
case R.id.nav_settings: {
Intent intent = new Intent(MainActivity.this, SettingsActivity.class);
startActivity(intent);
} break;
case R.id.nav_feedback: {
Intent intent = new Intent(MainActivity.this, FeedbackActivity.class);
startActivity(intent);
}
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
#Override
public void onBackPressed() {
assert drawerLayout != null;
if(drawerLayout.isDrawerOpen(GravityCompat.START)){
drawerLayout.closeDrawer(GravityCompat.START);
}
else{
super.onBackPressed();
}
}
public void onClickHome(View view){
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, new Fragment_home()).commit();
}
public void onClickFilter(View view){
Intent intent = new Intent(MainActivity.this, FIlterActivity.class);

}

It's like when i use Activity and Fragment it's very laggy. Is there other way to do smooth?
Solution: I used handler. But it's not best.
case R.id.nav_settings: {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(MainActivity.this, SettingsActivity.class);
startActivity(intent);
}
}, 250);
} break;

How to change length for adding more fragment.I am not able to add new fragment.

java.lang.ArrayIndexOutOfBoundsException: length=5; index=5?
Looks like Exception happens when you call:
getSupportActionBar().setTitle(activityTitles[navItemIndex]);
navItemIndex has range from 0 to 5 (a.e. length 6) when activityTitles has only 5 items
Solution:
Set 6 items for activityTitles

Navigation Item Selected State through Multiple Activities

I have a working Navigation Drawer through out multiple activities and I am looking to highlight the current Navigation Item Selected after it changes the activity. How can I save the Item Selected Listener through out the whole app while the onCreateDrawer its recreating itself on every other activity?
If you need any other relevant activity or have any feedback, dont hesitate to indulge me!

Once I also had similar problem. And here is what worked for me:
Change menu ids and class names as per your situation.
private void setupNavDrawer() {
// ...
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
switch (menuItem.getItemId()) {
case R.id.mainSection:
drawerLayout.closeDrawers();
startNewActivity(MainActivity.class);
break;
case R.id.allGames:
drawerLayout.closeDrawers();
startNewActivity(GamesActivity.class);
break;
return true;
}
});
setNavigationViewCheckedItem();
// .....
}
And here setNavigationViewCheckedItem mehod:
private void setNavigationViewCheckedItem() {
if (this.getClass().equals(MainActivity.class)) {
navigationView.setCheckedItem(R.id.mainSection);
} else if (this.getClass().equals(GamesActivity.class)) {
navigationView.setCheckedItem(R.id.allGames);
}
}

android toolbar with fragments

I have toolbar and framelayout(for fragments) in my main activity layout. I have to show the toolbar in every fragments. But the issue is each fragment has different background image that is dynamically changing. Toolbar menu icon is used for navigation drawer open and close operation. How I will handle these issue?

Before posting the code block let's first understand what are we are going to do.
1.Create a HomeActivity that holds all the fragments.
Here is the activity_home.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_home"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_home"
app:menu="#menu/activity_home_drawer" />
</android.support.v4.widget.DrawerLayout>
Here is the app_bar_home.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
the other xmls of navigationview -- activity_home_drawer.xml contains navigation drawer contents and nav_header_home.xml is the navigation drawer header layout.
2.Let's come to java part of the HomeActivity.java
public class HomeActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener{
private HomeBean bean;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
ButterKnife.bind(this);
initListener();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//this menu contains all the common menu item actions
getMenuInflater().inflate(R.menu.home, menu);
return true;
}
//common options bar item click here i have notifications icon common for all the fragments
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// 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.
switch (item.getItemId()){
case R.id.action_notifications:
AppUtils.launchActivity(HomeActivity.this, NotificationActivity.class,intentData);
return false;
default:
return super.onOptionsItemSelected(item);
}
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// Handle navigation view item clicks here.
Fragment selectedFragment = null;
switch (item.getItemId()){
case R.id.nav_dashboard:
//you can cache this fragment in case of repeated creations
selectedFragment = new DashBoardFragment();
}
break;
}
if(selectedFragment != null){
displayFragment(selectedFragment);
DrawerLayout drawer = ButterKnife.findById(this,R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
}
return true;
}
private void displayFragment(Fragment fragment) {
if(fragment !=null){
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_frame, fragment);
ft.commit();
}
}
#Override
public void initToolBar() {}
public void setToolbar(Toolbar toolbar){
setSupportActionBar(toolbar);
setActionBarToggle(toolbar);
}
private void setActionBarToggle(Toolbar toolbar) {
DrawerLayout drawer = ButterKnife.findById(this, R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open,
R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
}
#Override
public void initListener() {
NavigationView navigationView = ButterKnife.findById(this,R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
//as the first item is show by default
navigationView.getMenu().getItem(0).setChecked(true);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
}
Now as an example let see how the fragments are written.
public class SettingsFragment extends Fragment {
#BindView(R.id.toolbar)
Toolbar toolbar;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_settings,container,false);
ButterKnife.bind(this,view);
return view;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
((HomeActivity)getActivity()).setToolbar(toolbar);
}
}
Corresponding fragment xml fragment_settings.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

app:title="#string/settings"/>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_settings" />
</android.support.design.widget.CoordinatorLayout>
the corresponding xml content_settings.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="#dimen/min_widget_padding"
android:id="#+id/nsv_settings_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
// your content goes here
</<android.support.v4.widget.NestedScrollView>
I hope this gives clear picture on how to do in case if you have any other doubts please comment.

Use this code. I helped
public class MyFragment extends Fragment {
public void onCreate(Bundle savedInstanceState) {
setHasOptionsMenu(true);// To enable actionbar in fragments
super.onCreate(savedInstanceState);
}
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
//Here it is necessary to connect the layout menu
inflater.inflate(R.menu.fragment2, menu);
super.onCreateOptionsMenu(menu, inflater);
}
}

}
}
}
How can i it? tnx <3

put this line
startActivity(new Intent(getApplicationContext(), Recycler_Page.class));
in
private void setupDrawerContent(NavigationView navigationView)
so updated method is like:
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
startActivity(new Intent(getApplicationContext(), Recycler_Page.class));
mDrawerLayout.closeDrawers();
return true;
}
});
}

The navigation view does not use the onOptionsItemSelected method, instead you need to call navigationView.setOnNavigationItemSelectedListener
