Progressbar in ActionBar

Progressbar in ActionBar - android

I am working with an app which will load a website Inside the app .Now i want to add a ProgressBar in action bar without swipe up to repress feature.
Like that
I am using Fragment in my app.
WebviewFragment
public class WebviewFragment extends Fragment {
WebView webView;
String newslink;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_webview, container, false);
newslink = getArguments().getString("LINK");
webView = (WebView) view.findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(newslink);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
webView.goBack();
return true;
}
return false;
}
});
return view;
}
}
fragment_webview.XML
<?xml version="1.0" encoding ="utf-8"?
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swipe_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView" />
</LinearLayout>
Any solution for me ?

if you want add progress to actionbar call this method before setlayout
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
UPDATE where should request window feature
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.activity_main);
.... // other code goes here
}
and call this method when you want run it
EDIT in fragment you can add getActivity() before requestWindowFeature to be getActivity().requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true); // turn progress on
setProgressBarIndeterminateVisibility(false); // turn progress off
hope this work , my recommendation to use toolbar
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/material_green_500"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<ProgressBar
android:id="#+id/toolbar_progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateTint="#795548"
android:indeterminateTintMode="src_in"
android:layout_gravity="right"
/>
</android.support.v7.widget.Toolbar>
Why I recommended toolbar with ProgressBar ?
for two reasons , First setSupportProgressBarIndeterminate deprecated.
Second easy to use just set setVisibility method to make it visible call setVisibility(View.VISIBLE);
to hide view call setVisibility(View.GONE);

Materialio Appbar does not hide when scrolling down

I've followed the material documentation for top app bars and implemented a part of it in my app to be able to hide it, when scrolling down my list.
My Layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:id="#+id/ddd"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".pkgTestforend.DriverListFragment">
<com.example.dochjavatestimplementation.pkgTestforend.CustomLinearLayout
android:layout_width="match_parent"
android:id="#+id/cusLL"
android:layout_height="match_parent"
app:elevation="0dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listAllDrivers"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
</com.example.dochjavatestimplementation.pkgTestforend.CustomLinearLayout>
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:liftOnScroll="true" >
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/topAppBar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:title="PageTitle"
app:menu="#menu/top_app_bar"
app:layout_scrollFlags="scroll|enterAlways|snap"
app:navigationIcon="#drawable/baseline_menu_24"
style="#style/Widget.MaterialComponents.Toolbar.Primary"
/>
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
And the corresponding fragment:
public class DriverListFragment extends Fragment implements View.OnClickListener {
public DriverListFragment() {
}
public static DriverListFragment newInstance(String param1, String param2) {
return new DriverListFragment();
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_driver_list, container, false);
setUpToolbar(view);
return view;
}
private void setUpToolbar(View view) {
Toolbar toolbar = view.findViewById(R.id.topAppBar);
AppCompatActivity activity = (AppCompatActivity) getActivity();
if (activity != null) {
activity.setSupportActionBar(toolbar);
}
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater menuInflater) {
menuInflater.inflate(R.menu.top_app_bar, menu);
super.onCreateOptionsMenu(menu, menuInflater);
}
ListView listViewDriver;
DriverListAdapter adapter;
RoomWithRxJavaViewModel viewModel;
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
listViewDriver = view.findViewById(R.id.listAllDrivers);
viewModel = new RoomWithRxJavaViewModel(getActivity().getApplication());
Disposable d = viewModel.getDrivers()
.subscribe(allusers ->
{
adapter = new DriverListAdapter(getContext(), (ArrayList<Driver>) allusers);
listViewDriver.setAdapter(adapter);
}, e -> {
//show err mes
}
);
}
}
The setup is pretty simple build.
I just have a custom linearlayout which I am planning to modify later. And yes, the relative layout for the listview is on purpose so I can easily modify my future button positions.
The result looks like this:
So the issue is that, altough the app bar at the top is visible, it wont hide when I scroll down my list (see picture above), eventough I am using app:liftOnScroll="true" and app:layout_scrollFlags="scroll|enterAlways|snap".
What am I missing exactly? Is it cause I use my custom linearlayout?
Putting the appbar before the custom linearlayout didn't change the output unfourntatly.

SwipeRefreshLayout conflict with scroll down in WebView

In my WebView application SwipeRefreshLayout doesn't work because when I scroll down it triggers page reload function.
One solution I think would be limit the pull-to-refresh layout. I tried this and it doesn't seem to work.
Here is my implementation:
Java file
SwipeRefreshLayout mySwipeRefreshLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySwipeRefreshLayout = (SwipeRefreshLayout)this.findViewById(R.id.swipeContainer);
String URL = "my_url";
mWebView = (WebView) findViewById(R.id.enyakin);
WebSettings webSettings = mWebView.getSettings();
mWebView.loadUrl(URL);
webSettings.setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
// Phone call function if this matters
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:"))
{
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
startActivity(intent);
return true;
}
view.loadUrl(url);
return true;
}
});
mySwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
mWebView.reload();
if (null != mySwipeRefreshLayout) {
mySwipeRefreshLayout.setRefreshing(false);
}
}
}
);
XML file
<RelativeLayout 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"
tools:context="com.google.firebase.quickstart.fcm.MainActivity"
tools:showIn="#layout/activity_main">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:fillViewport="true">
<WebView
android:id="#+id/enyakin"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.NestedScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
Can you help me to understand how can I seperate those two scrolling features?
Edit:
Looked here this doesn't answer my question

use setOnChildScrollUpCallback to control when a refresh should be triggered.
Here is the sample code in kotlin.
mySwipeRefreshLayout.apply {
setOnRefreshListener {
// Handle refresh
}
setOnChildScrollUpCallback {parent, child ->
// Return true to disable swiping to refresh.
// You can get scrolling position of nested scroll view and only return true when it is larger than 0.
}
}

SwipeRefreshLayout and to handle external links in webview( manual class) not working together in android webview

I am using webview in android i have implemented pull to refresh in webview. Also i have created a class that handles the external links inside the website to open the links within the app only but the problem is reloader keeps on loading like this
xml file of webview fragment
<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">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipe2"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<WebView
android:id="#+id/Zomato"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
/>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
SwipeLayout in the Desc.java
SwipeRefreshLayout swipe;
static WebView webView;
#Override
public void onViewCreated(#NonNull final View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
webView=view.findViewById(R.id.Zomato);
swipe=view.findViewById(R.id.swipe2);
}
swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
String url = "https://www.zomato.com/";
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
swipe.setRefreshing(false);
}
});
}
webView.setWebViewClient(new Fragment2.GeoWebViewClient());

Hi Actually you are doing wrong because here you are setting web view client tow time means it will override first one so please set only first time and put logic in that onPageFinished it will work. Referer bellow answer

Load webview in the top of the page

I'm working in a WebView App.
In my last change, i added a function to hide the app bar when i scroll down in webview. Nice !!!
But i have noticed a problem. I will try explain.
Let's suposse that i'm in a News Site, and i'm openning the last news. The most recent news are in the start of the page, and the last news are close to the ends of the page, so i open the last news, and my webview load the url. When the url is loaded, my webview is in the end of the site, and not in the start. It started after i added my "webview" inside of "NestedScrollView". Looks like NestedScrollView is saving my position, and it's affecting my position in the web page. How to fix this ?
Edit: My webview is load inside Framelayout, my webview is a fragment.

1) Make id for the NestedScrollView
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/nested_scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_vertical">
2) Create NestedScrollView object
3) When the new URL is loaded, set the scroll property of the nestedScrollViewobject to 0,0.
nestedScrollViewObj.scrollTo(0, 0);

Hiding/Showing the toolbar when fragment in the tabs is scrolled

I added the new Toolbar, Tablayout and Viewpager in my android app. I provided Fragments for my 3 Tabs and its working fine. But the problem is that when i scroll up my Toolbar does not hide. I want that when i scroll my fragment it should hide. And one more thing, i am using Webview in the fragment.
My codes are given below.
MainActivity.Java
public class MainActivity extends AppCompatActivity {
TabLayout tabLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setupToolbar();
setupTablayout();
}
private void setupToolbar() {
// TODO Auto-generated method stub
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarsdfs);
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);}
}
private void setupTablayout() {
// TODO Auto-generated method stub
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override

}
});

What i want?
What i want is that when i scroll the webview upwards, the toolbar should also scroll upwards and hides and when i scroll back down the toolbar should come back as soon as possible.

Try this.

Firstly, You should move your webview into NestedScrollView and set 'android:isScrollContainer' property to 'false' value. https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
Secondly, You should move your ViewPager outside the AppBarLayout.
So, your main.xml should be like this:
<?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"
android:id="#+id/main_content"
android:background="#FFF"
android:clickable="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<!-- your app bar stuff here -->
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="240dp"
app:layout_scrollFlags="scroll|enterAlways">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:id="#+id/image_header"/>
<include layout="#layout/header"/>
</FrameLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:background="#FFF"
app:tabTextColor="#a3a3a3"
app:tabSelectedTextColor="#a3a3a3"
app:tabIndicatorColor="#0042ab"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:background="#eaeaea"/>
AppBarLayout childern will hide only if they have flag app:layout_scrollFlags
Read more about implementing support design library here:

You should move your ViewPager outside the AppBarLayout and add behavior to ViewPager app:layout_behavior="#string/appbar_scrolling_view_behavior"

How to properly hide&show the actionbar using the new design library API?
Android-ObservableScrollView

im sorry about my english.
I'll show you how i've made that for my app (min sdk: 14, target sdk: 22). I dont use fragments, i only have a single webview in my activity, but the handler is the same. The probles is when you make scroll inside a webview, Android doesn't handle that like a scroll event, the webview handles his own events.
First i define the styles.xml in res folder. I use a transparent and overlayed ActionBar, thats better when you want to hide and show that:
res/styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="#android:style/Theme.Holo">
<!-- Customize your theme here. -->
<item name="android:windowActionBarOverlay">true</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ACTION BAR STYLES -->
<style name="MyActionBar" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:background">#color/actionbar_background</item>
</style>
</resources>
then at the manifest, i define the styles for the app and the ActionBar in the application section:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
finally in the MainActivity, you must control the gestures in the webview. You must implements the View.OnTouchListener, and the Handler.Callback. When you touch on the webview, you must compare the start event and the end event:
MainActivity.Java
public class MainActivity extends Activity implements View.OnTouchListener, Handler.Callback {
private float x1,x2,y1,y2; //x1, y1 is the start of the event, x2, y2 is the end.
static final int MIN_DISTANCE = 150; //min distance for a scroll up event
private static final int CLICK_ON_WEBVIEW = 1;
private static final int CLICK_ON_URL = 2;
private static final int UP_ON_WEBVIEW = 3;
private final Handler handler = new Handler(this);
public WebView webView;
private WebViewClient client;
private WebAppInterface webAppInt = new WebAppInterface(this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView)findViewById(R.id.myWebView);
webView.setOnTouchListener(this);
client = new WebViewClient();
webView.setWebViewClient(client);
webView.loadDataWithBaseURL("file:///android_asset/", "myweb.html", "text/html", "UTF-8", "");
}
//HERE START THE IMPORTANT PART
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() == R.id.myWebView && event.getAction() == MotionEvent.ACTION_DOWN){
x1 = event.getX();
y1 = event.getY();
handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 200);
} else if (v.getId() == R.id.myWebView && event.getAction() == MotionEvent.ACTION_UP){
x2 = event.getX();
y2 = event.getY();
handler.sendEmptyMessageDelayed(UP_ON_WEBVIEW, 200);
}
return false;
}
#Override
public boolean handleMessage(Message msg) {
if (msg.what == CLICK_ON_URL){ //if you clic a link in the webview, thats not a scroll
handler.removeMessages(CLICK_ON_WEBVIEW);
handler.removeMessages(UP_ON_WEBVIEW);
return true;
}
if (msg.what == CLICK_ON_WEBVIEW){
Toast.makeText(this, "WebView clicked", Toast.LENGTH_SHORT).show();
return true;
}
if (msg.what == UP_ON_WEBVIEW){
float deltaX = x2 - x1; //horizontal move distance
float deltaY = y2 - y1; //vertical move distance
if ((Math.abs(deltaX) > MIN_DISTANCE) && (Math.abs(deltaX) > Math.abs(deltaY)))
{
// Left to Right swipe action
if (x2 > x1)
{
Toast.makeText(this, "Left to Right swipe [Next]", Toast.LENGTH_SHORT).show ();
}
// Right to left swipe action
else
{
Toast.makeText(this, "Right to Left swipe [Previous]", Toast.LENGTH_SHORT).show ();
}
}
else if ((Math.abs(deltaY) > MIN_DISTANCE) && (Math.abs(deltaY) > Math.abs(deltaX)))
{
// Top to Bottom swipe action -- i SWOW MY ACTIONBAR ON SCROLLDOWN
if (y2 > y1)
{
getActionBar().show();
Toast.makeText(this, "Top to Bottom swipe [Show Bar]", Toast.LENGTH_SHORT).show ();
}
// Bottom to top swipe action -- I HIDE MY ACTIONBAR ON SCROLLUP
else
{
getActionBar().hide();
Toast.makeText(this, "Bottom to Top swipe [Hide Bar]", Toast.LENGTH_SHORT).show ();
}
}
return true;
}
return false;
}
}
I hope thats helps you.

To hide the menu for a specific fragment:
setHasOptionsMenu(true); //Inside of onCreate in FRAGMENT:
#Override
public void onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.action_search).setVisible(false);
}

Just add this line in your toolbar or FAB button.
app:layout_scrollFlags="scroll|enterAlways"
The app:layout_scrollFlags="scroll|enterAlways" line will cause that our Toolbar will scroll of the screen when user scrolls down the list and as soon as he starts scrolling up the Toolbar will show up again. Clean and simple, that’s the power of CoordinatorLayout!
Kindly have look over this link
https://mzgreen.github.io/2015/06/23/How-to-hideshow-Toolbar-when-list-is-scrolling(part3)/&re=1&ts=1453224208&sig=ALL1Aj5aKrtAlylt-Qt3Ci6uwff76BqQYw

Simply putting app:layout_scrollFlags="scroll|enterAlways" onto your toolbar will suffice.
