This is MainActivity I gave a normal swipe refresh layout code which is working in emulator but not in real devices..
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
swipe = (SwipeRefreshLayout) findViewById(R.id.swipe);
swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
LoadWed();
}
});
LoadWed();
public void LoadWed(){
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setAppCacheEnabled(true);
swipe.setRefreshing(true);
webView.loadUrl("https://localhost/admin");
webView.getSettings().setDomStorageEnabled(true);
swipe.setColorSchemeResources(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
}

Added FrameLayout as a first child of DrawerLayout. And added TextView, ProgressBar, SwipeRefreshLayout as a child of that FrameLayout and now it works as expected.
Like This

android - menu item not showing in action bar

I'm trying to add menu item "done" in the action bar. I just copied and modified the code from another activity that has menu items showing. So it should work properly.
Here's the activity layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/md_blue_600"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:id="#+id/activity_credits"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:mContext="com.getsaveit.saveit.activities.CreditsActivity">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="18sp"
android:layout_marginBottom="#dimen/activity_vertical_margin"
android:text="#string/affiliator_category"/>
<com.toptoche.searchablespinnerlibrary.SearchableSpinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintText="Select category"
android:id="#+id/affiliator_category_spinner"/>
<ExpandableListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/rectangular_shap"
android:id="#+id/affiliators_listview"/>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
And choose_affiliator_menu.xml file :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:title="#string/done"
android:orderInCategory="1"
android:id="#+id/next_btn"
app:showAsAction="always" />
</menu>
And the java code itself:
public class CreditsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_credits);
Toolbar actionBar = (Toolbar) findViewById(R.id.toolbar);
actionBar.setTitle("Memberships");
//....
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.choose_affiliator_menu, menu);
return true;
}
}

You should use below method after initialization of Toolbar.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

Center App Bar title on Android

I'm trying to create my own custom app bar with a center-aligned title. Android Studio's editor shows my title is properly centered, but it is not on my actual device.
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar myToolbar = (Toolbar) findViewById(R.id.encounter_toolbar);
setSupportActionBar(myToolbar);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.encounter_menu_bar_layout);
}
encounter_menu_bar_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<TextView
android:id="#+id/encounter_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/untitled"
android:textSize="20sp"
android:textColor="#color/titleTextColor"
android:textStyle="bold"
android:layout_gravity="center" />
</LinearLayout>
encounter_menu_bar.xml doesn't have anything in it:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
</menu>
EDIT
A lot of you are recommending that I change android:layout_gravity to android:gravity. I've tried that as well and I'm still not getting it to line up properly.
I'm enabling the app bar to show up on a specific fragment, as shown here:
EncounterFragment.java
public class EncounterFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
return inflater.inflate(R.layout.fragment_encounter, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater menuInflater) {
menuInflater.inflate(R.menu.encounter_menu_bar, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO: This
return super.onOptionsItemSelected(item);
}
}
I also forgot to mention that I'm attaching the menu in a fragment. This is its layout:
fragment_encounter.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/encounter_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</LinearLayout>

Try adding android:gravity="center".
This happens because you have to center the whole text and not just the layout

Use android:layout_gravity="center"
Example:
<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_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
NOTE: layout_gravity, not gravity
In your case:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<TextView
android:id="#+id/encounter_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="#string/untitled"
android:textSize="20sp"
android:textColor="#color/titleTextColor"
android:textStyle="bold"
android:layout_gravity="center" />
</LinearLayout>

Change the textview to this
make it match parent for width, And make gravity center to center the text
<TextView
android:id="#+id/encounter_name"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="#string/untitled"
android:textSize="20sp"
android:textColor="#color/titleTextColor"
android:textStyle="bold"
android:gravity="center" />

You want to change your xml view to this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
#this should be horizontal, not vertical.
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<TextView
android:id="#+id/encounter_name"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="#string/untitled"
android:textSize="20sp"
android:textColor="#color/titleTextColor"
android:textStyle="bold"
/>
To start, you need to make your linear layout horizontal, not vertical. By making it vertical, you are aligning it to the left.
Then, you need to make sure that your textview width and height match the parent, rather than just wrap the content. Then you can use the gravity attribute to make sure that the text is centered. When you used gravity before, the textview simply wrapped the content, and thus it didn't center in the textview. By matching the parent view bounds, you will be able to then center the text as you need to.

This is how your Toolbar XML should be
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:titleTextColor="#android:color/white"
android:background="?attr/colorPrimary">
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Toolbar Title"
android:textColor="#android:color/white"
style="#style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_gravity="center"
/>
</android.support.v7.widget.Toolbar>
Then in your Activity
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);

Android - fragments don't show

I created one acivity and a few fragments. I try to show one of them after start-up but I see empty screen, without fragments (but with NavigationDrawer)
What do I do wrong?
I have no idea where my mistake is.
Thank you!
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportFragmentManager().beginTransaction()
.replace(R.id.content, new DashboardFragment()).commit();

</android.support.v7.widget.CardView>

first you should add fragment :
FragmentManager fm=getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add([FRAGMENT],[STRING TAG]);
ft.commit();

I've just implemented a scrollview but then during deployment, I get this error and I don't know why + don't know what's wrong with my code.

You're setting your content view to the fragment's layout. That's not what you want. You want to set it to the activity's layout, R.id.activity_about
