I tried to implement my toolbar with my activity but it's not inflating and keeps showing an error. My project does not use AppCompat but I'm not sure whether or not that is also the vause of the error.
Error inflating class android.widget.Toolbar
Java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar customToolbar = findViewById(R.id.toolbar_1line);
setActionBar(customToolbar);
//add back arrow to toolbar
if (getActionBar() != null){
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(true);
}
TextView mTitle = this.findViewById(R.id.toolbar_title);
mTitle.setText(getString(R.string.select_a_destination_station));
mTitle.setTextColor(Color.WHITE);
mTitle.setEllipsize(TextUtils.TruncateAt.MARQUEE);
mTitle.setMarqueeRepeatLimit(-1);
mTitle.setSingleLine(true);
mTitle.setSelected(true);
}
}

Try this.
In the Toolbar_layout
One way
change
<android.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize">
</android.widget.Toolbar>
to
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize">
</android.support.v7.widget.Toolbar>
In the java code
change
Toolbar customToolbar = findViewById(R.id.toolbar_1line);
setActionBar(customToolbar);
//add back arrow to toolbar
if (getActionBar() != null){
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(true);
}
to
Toolbar customToolbar = (Toolbar) findViewById(R.id.toolbar_1line);
setSupportActionBar(customToolbar);
//add back arrow to toolbar
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
Another way
change
<android.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize">
</android.widget.Toolbar>
to
<Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize">
</Toolbar>
It's easy.

My toolbar on top of my activity appears blank but it should have a navigation custom icon and a title but neither is visible?
Here is my xml
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay" />
here is my activity
class MyActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_me)
setupToolbar()
}
private fun setupToolbar() {
setSupportActionBar(toolbar)
toolbar.setNavigationIcon(R.drawable.ic_close)
toolbar.setNavigationOnClickListener {
onBackPressed()
}
toolbar.setTitle(R.string.profile_unfollow_warning)
supportActionBar!!.setHomeButtonEnabled(true)
supportActionBar!!.setDisplayShowCustomEnabled(true)
supportActionBar!!.setDisplayHomeAsUpEnabled(true)
supportActionBar!!.show()
}
}
Theme i am using for this activity
<activity android:name=".ui.profile.MyActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait"
android:theme="#style/Theme.MaterialComponents.NoActionBar"/>
public class MainActivity {
// Declaring the Toolbar Object
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// Attaching the layout to the toolbar object
toolbar = (Toolbar) findViewById(R.id.tool_bar);
// Setting toolbar as the ActionBar with setSupportActionBar() call
setSupportActionBar(toolbar);
}
Create a xml file like tool_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:elevation="4dp" />
Include the Toolbar into your main_activity.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include
android:id="#+id/tool_bar"
layout="#layout/tool_bar" />
<TextView
android:layout_below="#+id/tool_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/TextDimTop"
android:text="#string/hello_world" />
</RelativeLayout>
Opps, It seems to be a bug in ordering
setSupportActionBar(toolbar)
supportActionBar?.setDisplayHomeAsUpEnabled(true)
supportActionBar?.setTitle(R.string.profile_unfollow_warning)
supportActionBar?.setHomeButtonEnabled(true)
supportActionBar?.setDisplayShowCustomEnabled(true)
toolbar?.setNavigationIcon(R.drawable.ic_close)
toolbar?.setNavigationOnClickListener {
onBackPressed()
}
I wonder why such a strange behavior in the app attribute: elevation = "0dp" and how to solve the problem. I use the androidx library. The toolbar is transparent. Shadow remains. When I write an app: elevation = "0dp", the shadow disappears, but the toolbar buttons, including the "back" buttons, stop responding.
I tried to solve it in other ways: android: elevation = "0dp"
programmatically set getSupportActionBar (). setElevation (0); Does not help.

Try the below code snippet instead of toolbar.setNavigationOnClickListener

return super.onOptionsItemSelected(item);
}
hope this will solve your problem.
thanks
This is just because you have used FrameLayout as a parent - and also removed elevation from AppBarLayout, and due to this, Your ScrollView is overlapping your AppBarLayout as it is written below AppBarLayout. change your root to something else, for eg.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:theme="#style/AppTheme.AppBarOverlay">

I am trying to add a toolbar to my PreferenceActivity.
I have looked around here and a number of places and nothing seems to work.
I am using headers for my top-level.
I tried to then use my own layout in onCreate including the required toolbar and making sure it has a view by the name of "#android:id/list".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:title="#string/app_name"
app:navigationIcon="#drawable/back"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<ListView android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
This worked okay for the top level but then the next level failed looking for a view name "android:id/prefs".
java.lang.IllegalArgumentException: No view found for id 0x102040a (android:id/prefs) for fragment PreferencesFragmentButtonInteraction{7a6584a #0 id=0x102040a}
The only code in the onCreate of the fragment is the AddPreferencesFromResource.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences_button_interaction);
}
I have tried to use a theme and set in in the manifest but to no avail.
You can use PreferenceFragmentCompat wrapped in a normal AppCompatActivity. Then you can easily attach an appbar to your activity using
setContentView(R.layout.activity_setting);
and preferences can be set to the fragment using
setPreferencesFromResource(R.xml.preferences_button_interaction, rootKey);
If you wish to add toolbar to your current activity, you can try this method
private void setupActionBar() {
ViewGroup rootView = (ViewGroup)findViewById(R.id.action_bar_root); //id from appcompat
if (rootView != null) {
View view = getLayoutInflater().inflate(R.layout.app_bar_layout, rootView, false);
rootView.addView(view, 0);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
// Show the Up button in the action bar.
actionBar.setDisplayHomeAsUpEnabled(true);
}
}

On my phone and that of a friend, the FAB in the default Android Studio Activity does not move down after the Snackbar dismisses.
On the emulator and a few other friends' phones, it does animate down.
The first friend and I have changed animation scale to 0.5, but setting it to 1.0 and rebooting hasn't fixed the issue.
This should have been fixed in Design Support Library 23.2.0, and I am using 23.3.0, as the example comes with that set.
Edit:

As suggested by #ianhanniballake, this was fixed in Design Support Library 23.4.0.
I want to change the app I have created so far, in order to implement a ListView. I followed this example and this example. The examples alone work, but not together with the changes I had to make to my so-far existing app.
I have a avticity_main.xml defined as follows:
<android.support.design.widget.CoordinatorLayout
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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity" >
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_grid"
android:useDefaultMargins="true"
android:alignmentMode="alignBounds"
android:columnOrderPreserved="false"
android:columnCount="4"
>
<TextView
android:text="MainTitle"
android:textSize="32dip"
android:layout_columnSpan="4"
android:layout_gravity="center_horizontal"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
and I have the following code for my main activity:
public class MainActivity extends AppCompatActivity {
static final String[] MOBILE_OS =
new String[] { "Android", "iOS", "WindowsMobile", "Blackberry"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ListView list = (ListView) findViewById(R.id.list);
list.setAdapter(new ListAdapter(this, MOBILE_OS));
The code compiles fine, but no list is shown.
ListActivity is a "convenience" class to implement a simple ListView. And that's pretty much all you can do. So, there's no setSupportActionBar(Toolbar) there.
To achieve what you want, use AppCompatActivity or default Activity.
This link provides a nice tutorial on how to use the new ToolBar instead of the old ActionBar.
You want something like this:
This layout example could be used:
P.S.: "#color/primary" could be any color like #FF009688.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent" android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="#+id/toolbar"
android:background="#color/primary"
android:elevation="4dp">
</android.support.v7.widget.Toolbar>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar"
android:id="#+id/lv"></ListView>
</RelativeLayout>
And on the Java side:
YourActivity.java
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
lv = (ListView) findViewById(R.id.lv);
setSupportActionBar(toolbar);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
}
// Populate the ListView here...
}
}
EDIT: This other answer of mine can show you how to create a Custom Adapter to display the data you want on the ListView.
Second edit: Use this layout
<android.support.design.widget.CoordinatorLayout

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"/>

<LinearLayout

android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
What did I do?
Your LinearLayout was lacking the orientation parameter on the XML, and your TextView had a android:layout_height set to match_parent, so it was filling the entire layout. I've changed it to wrap_content and you're good to go.
setSupportActionBar(toolbar) is not available in ListActivity. You can use AppCompatActivity instead and just get a reference to the listview:
ListView list = findViewById(R.id.list); and use list.setAdapter(adapter) instead of setListAdapter(adapter);
You can't do that in ListActivity.
If you want to access getSupportActionBar(), you need to extent your class by AppCompatActivity.
My Suggestion : Don`t use ListActivty is you want to use ToolBar. Create an Activity and then only have ListView within that Activity. It'll work just fine.
OR
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
// Set an OnMenuItemClickListener to handle menu item clicks
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// Handle the menu item
return true;
}
});
// Inflate a menu to be displayed in the toolbar
toolbar.inflateMenu(R.menu.your_toolbar_menu);
}`
You can use the new AppCompatDelegate component provided by the Support Library to easily add a Toolbar to your ListActivity.
