I use the setActionBarTitle(); to change the title of the action bar it work fine in onCreate() method but it did not work when i want to implement it on button click listener
public class ScrollingActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scrolling);
toolbar = (Toolbar) findViewById(R.id.toolbar);
CollapsingToolbarLayout mToolbarlayout= (CollapsingToolbarLayout) findViewById(R.id.toolbar_layout);
setSupportActionBar(toolbar);
Button newbutton= (Button) findViewById(R.id.changetitle);
if (newbutton != null) {
newbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(ScrollingActivity.this, "Hi", Toast.LENGTH_SHORT).show();
setActionBarTitle("HI");
}
});
}
}
public void setActionBarTitle(String title) {
//noinspection ConstantConditions
getSupportActionBar().setTitle(title); //check not working
}
}
The xml which is used for the activity in which i want to change the title
<?xml version="1.0" encoding="utf-8"?>

Yes you are right that in onCreate() the Title of ActionBar/ToolBar changes , and if we call the method to change the Title on Button click it doesn't.
The button is defined in the:
<include layout="#layout/content_scrolling"/>
I tried many different ways and stumbled upon this issue https://code.google.com/p/android/issues/detail?id=77763
I have a work around if you would like to try (to change title)
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
android.support.v7.app.ActionBar actionBar;
CollapsingToolbarLayout mToolbarlayout;
Button newButton;
// On every click I will change the value of i
static int i=1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
mToolbarlayout= (CollapsingToolbarLayout) findViewById(R.id.toolbar_layout);
newButton= (Button) findViewById(R.id.changetitle);
setSupportActionBar(toolbar);
actionBar=getSupportActionBar();
newButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//oldWay();
newWay();
}
});
}
private void oldWay() {
Toast.makeText(MainActivity.this, ""+actionBar.getTitle(), Toast.LENGTH_SHORT).show();
actionBar.setTitle("Something Else");
Toast.makeText(MainActivity.this/, ""+actionBar.getTitle(), Toast.LENGTH_SHORT).show();
//Toast says that value has changed, but it doesn't on screen
}
private void newWay() {
mToolbarlayout.setTitle("" + i++);
}
}
Let me know if this helps or not.

I have a collapsing toolbar in MainActivity with a SearchView in toolbar. When the searchview icon is clicked the searchview gets collapsed in the toolbar. It works fine when the toolbar is collapsed. But if i click on the search icon and scroll up, the collapsed searchview will hide. I want to the collapsed searchview to be visible when scrolled up. I am following
this link MaterialSearchView
This is the screen when the collapsing toolbar is collapsed
Now if i click on the search icon the screen looks like this
Till now the searchview is working fine. Now if i scroll up the screen looks like this
Now if i click the search icon, the searchview gets collapsed but it gets hided. So i want the searchview to be collapsed in the toolbar even when the collapsing toolbar is not collapsed.
This is the screen shot which i want when the toolbar is not collapsed and the search icon is clicked
This is my activity_main.xml

#sendtodilanka the problem is that you add the Crosssfader as the parent of the main_content view, which is a direct child of your CoordinatorLayout.
As the CoordinatorLayout is similar to the FrameLayout and does overlap views your Crossfader will simply be displayed below the AppBarLayout which you have defined to be over the main_content.
To get the Crossfader below the Toolbar you should add a new View around your main_content, let's choose a FrameLayout which has the attribute (don't forget to define the appBarLayout id to your AppBarLayout)
xml
app:layout_behavior="#string/appbar_scrolling_view_behavior"
After this the Crossfader will get inflated as a child of the FrameLayout we added above, which is displayed below the AppBarLayout.
A more detailed information regarding this can be found here.
So your layout will look something like this:

I have an activity which has a coordinator layout with viewpager and CircularPager Indicator. I am trying to use MaterialRefreshLayout Library to do pull to refresh
The library can be found at Pull to refresh library
However, after I use pull to refresh my data, the viewpager just doesn't update the rest of the fragment and hence it dosn't scroll. Once I do background foreground it scrolls alright. Below is the Layout and activity

Not Sure what am I doing wrong here. Appreciate any suggestion.
use
mViewPager.setOffscreenPageLimit(numberOfPages);
Okay, figured since it is the activity that is not being refreshed itself I tried this.onResume() in the refresh method once I do notifyDataSetChanged(). It works.
Not sure it is the cleanest solution though

android:adjustViewBounds="true"
android:layout_height="match_parent" app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="?attr/colorPrimary">

android:layout_margin="#dimen/fab_margin" app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|end" android:src="#drawable/chatboxes" />
And this is the XML menu:
<menu 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" tools:context="com.compafone.app.ViewNews">
<item
android:id="#+id/action_comments"
android:title="Comments"
android:orderInCategory="200"
android:icon="#drawable/chatboxes"
app:showAsAction="ifRoom" />
<item
android:id="#+id/menu_item_share"
android:title="Partager"
android:icon="#android:drawable/ic_menu_share"
android:orderInCategory="100"
app:showAsAction="ifRoom"/>
Then, this is the Java activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_news);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.arrowleft);
fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
//On récupère l'intent
Intent i = getIntent();
id = i.getStringExtra("ID");
collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.toolbar_layout);
collapsingToolbarLayout.setExpandedTitleColor(getResources().getColor(android.R.color.transparent));
collapsingToolbarLayout.setTitle("Compafone");
appbar = (AppBarLayout) findViewById(R.id.app_bar);
new NewsListActivityLoad().execute();
title = (TextView) findViewById(R.id.news_title);
content = (TextView) findViewById(R.id.news_content);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu resource
getMenuInflater().inflate(R.menu.menu_view_news, menu);
MenuItem menuItem = menu.findItem(R.id.menu_item_share);
//mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; goto parent activity.
this.finish();
this.overridePendingTransition(0, R.anim.abc_fade_out);
return true;
case R.id.action_comments:
Intent intent = getIntent();
//Intent intent3 = new Intent(this, comments.class);
try {
//intent3.putExtra(Intent_ID, intent.getStringExtra(EXTRA_PROJET));
//intent3.putExtra(Intent_SUCCES, "null");
//startActivity(intent3);
} catch (Exception e) {
Log.i("notFoundProject", "Le projet n'existe pas");
}
return true;
case R.id.menu_item_share:
//doShare(shareintent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
So, I want to hide items from menu and display items only when users scroll down (When toolbar is in normal size, so display items at the same time when toolbar title is show in the toolbar).
Sorry for bad english, thanks in advance.
i am try to find my drawer layout but findViewById returns null and i don't know why... here is my code.
// NavigationBaseActivity
#Override
public void setContentView(int layoutResID) {
LayoutInflater.from(this).inflate(layoutResID, (ViewGroup) findViewById(R.id.content), true);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawerLayout != null) {
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.navigation_open, R.string.navigation_close);
drawerLayout.setDrawerListener(drawerToggle);
}
setupToolbar();
}
public class OverviewActivity extends NavigationBaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_overview);
}
}
My drawerLayout is always null... this is my xml layout file
