How to add Swipe Down Refresh feature in a Tab View Layout

This is the MainActivity of my Tab View Layout
package com.nitol.aust.cse.austclassmanager;
public class ResultCheckActivity extends AppCompatActivity implements
NavigationView.OnNavigationItemSelectedListener{
private TabLayout t1;
private ViewPager vp1;
Toolbar toolbar;
DrawerLayout drawerLayout;
NavigationView navigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navi_draw_result);
t1 = (TabLayout) findViewById(R.id.tab1);
vp1 = (ViewPager) findViewById(R.id.ViewPager1);
setUpMyViewPager(vp1);
t1.setupWithViewPager(vp1);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout) ;
navigationView = (NavigationView) findViewById(R.id.navigation_view);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle
(this,drawerLayout,toolbar, R.string.open_drawer, R.string.close_drawer);
drawerLayout.setDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
navigationView.setNavigationItemSelectedListener(this);
navigationView.getMenu().getItem(5).setChecked(true);
}
void setUpMyViewPager(ViewPager vp){
ViewPagerAdapter viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
viewPagerAdapter.addMyFragment(new WebViewEvents(),"News & Events");
viewPagerAdapter.addMyFragment(new WebViewAcademic(),"Academic Calendar");
viewPagerAdapter.addMyFragment(new WebViewTheory(),"Theory Results");
viewPagerAdapter.addMyFragment(new WebViewLab(),"Lab Results");
viewPagerAdapter.addMyFragment(new WebViewTeacher(),"Faculty Members");
vp.setAdapter(viewPagerAdapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> my_list = new ArrayList<Fragment>();
private final List<String> my_title = new ArrayList<String>();
public ViewPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
#Override
public Fragment getItem(int position) {
return my_list.get(position);
}
#Override
public int getCount() {
return my_list.size();
}
void addMyFragment(Fragment f, String title){
my_list.add(f);
my_title.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return my_title.get(position);
}
}
#Override
public void onBackPressed() {
if(drawerLayout.isDrawerOpen(GravityCompat.START)){
drawerLayout.closeDrawer(GravityCompat.START);
}
else{
super.onBackPressed();
}
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
switch (id){
case R.id.home:
Intent intent0 = new Intent(ResultCheckActivity.this, MenuActivity.class);
startActivity(intent0);
finish();
break;
case R.id.routine:
Intent intent = new Intent(ResultCheckActivity.this, ClassRoutineActivity.class);
startActivity(intent);
finish();
break;
case R.id.cgpa:
Intent intent2 = new Intent(ResultCheckActivity.this, CgpaCalculator.class);
startActivity(intent2);
finish();
break;
case R.id.details:
Toast.makeText(getApplicationContext(),"Class Details",Toast.LENGTH_SHORT).show();
break;
case R.id.quiz:
Toast.makeText(getApplicationContext(),"Quiz Reminder",Toast.LENGTH_SHORT).show();
break;
case R.id.result:
break;
case R.id.profile:
Intent intent3 = new Intent(ResultCheckActivity.this, ProfileActivity.class);
startActivity(intent3);
finish();
break;
case R.id.about:
Toast.makeText(getApplicationContext(),"About",Toast.LENGTH_SHORT).show();
break;
case R.id.settings:
Intent intent4 = new Intent(ResultCheckActivity.this, Settings.class);
startActivity(intent4);
finish();
break;
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_tool,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.tool_settings){
Intent intent = new Intent(ResultCheckActivity.this, Settings.class);
startActivity(intent);
}
else if(id == R.id.tool_about){
Toast.makeText(getApplicationContext(),"This is About !", Toast.LENGTH_SHORT).show();
}
return super.onOptionsItemSelected(item);
}
}
And this is my those tabs where i want to add refresh feature
void setUpMyViewPager(ViewPager vp){
ViewPagerAdapter viewPagerAdapter = new
ViewPagerAdapter(getSupportFragmentManager());
viewPagerAdapter.addMyFragment(new WebViewEvents(),"News & Events");
viewPagerAdapter.addMyFragment(new WebViewAcademic(),"Academic Calendar");
viewPagerAdapter.addMyFragment(new WebViewTheory(),"Theory Results");
viewPagerAdapter.addMyFragment(new WebViewLab(),"Lab Results");
viewPagerAdapter.addMyFragment(new WebViewTeacher(),"Faculty Members");
vp.setAdapter(viewPagerAdapter);
}
Now suppose i want to add refresh on "WebViewEvents" class. The class is given below
package com.nitol.aust.cse.austclassmanager;
public class WebViewEvents extends Fragment {
View v;
WebView wb4;
private String currentUrl = "http://aust.edu/news_events.htm";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.webview_event, container,false);
wb4 = (WebView) v.findViewById(R.id.webView_event);
wb4.setInitialScale(1);
wb4.getSettings().setJavaScriptEnabled(true);
wb4.getSettings().setLoadWithOverviewMode(true);
wb4.getSettings().setUseWideViewPort(true);
wb4.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
wb4.setScrollbarFadingEnabled(false);
wb4.loadUrl(currentUrl);
wb4.setWebViewClient(new WebViewClient());
wb4.getSettings().setBuiltInZoomControls(true);
wb4.getSettings().setUseWideViewPort(true);
wb4.getSettings().setLoadWithOverviewMode(true);
wb4.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
return v;
}
}
I found some instructions here but maximum of those was said that i have to #Override onRefresh() method...but i declared my class as a non activity class. so in a non activity class , i can not override a method. that's why i am not finding my solutions...

You just need to read docs on SwipeRefreshLayout
First, add SwipeRefreshLayout to your activity layout:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swiperefresh"
android:layout_width="match_parent"
android:layout_height="match_parent">
// here is your content
</android.support.v4.widget.SwipeRefreshLayout>
Then find instance of swipe refresh layout in your activity:
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefresh);
And set refresh listener in which trigger your update method
/*
* Sets up a SwipeRefreshLayout.OnRefreshListener that is invoked when the user
* performs a swipe-to-refresh gesture.
*/
mSwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
Log.i(LOG_TAG, "onRefresh called from SwipeRefreshLayout");
// This method performs the actual data-refresh operation.
// The method calls setRefreshing(false) when it's finished.
myUpdateOperation();
}
}
);
For more information read docs, link in the beginning of the answer.
Also you might look at google samples:
SwipeRefreshLayoutBasic
SwipeRefreshListFragment
List of all google samples you can find here
Hope it helps

Finally this is worked for me
package com.nitol.aust.cse.austclassmanager;
public class WebViewEvents extends Fragment{
View v;
WebView wb4;
SwipeRefreshLayout mySwipeRefreshLayout;
private String currentUrl = "http://aust.edu/news_events.htm";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.webview_event, container,false);
mySwipeRefreshLayout = (SwipeRefreshLayout) v.findViewById(R.id.swiperefresh);
wb4 = (WebView) v.findViewById(R.id.webView_event);
wb4.setInitialScale(1);
wb4.getSettings().setJavaScriptEnabled(true);
wb4.getSettings().setLoadWithOverviewMode(true);
wb4.getSettings().setUseWideViewPort(true);
wb4.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
wb4.setScrollbarFadingEnabled(false);
wb4.loadUrl(currentUrl);
wb4.setWebViewClient(new WebViewClient());
wb4.getSettings().setBuiltInZoomControls(true);
wb4.getSettings().setUseWideViewPort(true);
wb4.getSettings().setLoadWithOverviewMode(true);
wb4.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
wb4.setWebViewClient(new MyWebViewClient());
mySwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
wb4.loadUrl(currentUrl);
}
}
);
return v;
}
public class MyWebViewClient extends WebViewClient{
#Override
public void onPageFinished(WebView view, String url) {
mySwipeRefreshLayout.setRefreshing(false);
currentUrl = url;
super.onPageFinished(view, url);
}
}
}
I added this override method inside my class
mySwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
wb4.loadUrl(currentUrl);
}
}
);
Then added this to stop the refreshing animation
public class MyWebViewClient extends WebViewClient{
#Override
public void onPageFinished(WebView view, String url) {
mySwipeRefreshLayout.setRefreshing(false);
currentUrl = url;
super.onPageFinished(view, url);
}
}
Don't forget to add the instance of the last stopping animation impliment
wb4.setWebViewClient(new MyWebViewClient());

How to handle camera while switching between fragments?

I am switching between 2 different fragments using 2 buttons. One fragment has a camera view and opens pretty well for the first time, but when returning to the same fragment again from second fragment gives a blank screen. camera preview cannot be seen although camera hardware is free.I am NOT using camera2 api but needs a solution to this bug. i have added my complete code and images for assistance.

Can you try this, remove onAttach and onDetach. Also replace this code in onCreate
if (checkCameraHardware(getActivity().getApplicationContext())) {
Toast.makeText(this.getActivity(), "camera hardware is free", Toast.LENGTH_SHORT).show();
zXingScannerView = new ZXingScannerView(this.getActivity().getApplicationContext());
zXingScannerView.setResultHandler(this);
zXingScannerView.startCamera(0);
} else {
Toast.makeText(this.getActivity(), "camera hardware is NOT free", Toast.LENGTH_SHORT).show();
}
with this.
zXingScannerView = new ZXingScannerView(this.getActivity().getApplicationContext());
And change onPause and onResume like this.
#Override
public void onPause()
super.onPause(); {
if (zXingScannerView != null) {
zXingScannerView.stopCamera();
zXingScannerView.stopCameraPreview();
}
}
#Override
public void onResume() {
super.onResume();
if (checkCameraHardware(getActivity().getApplicationContext())) {
Toast.makeText(this.getActivity(), "camera hardware is free", Toast.LENGTH_SHORT).show();
zXingScannerView.setResultHandler(this); // Register ourselves as a
zXingScannerView.startCamera(0); // Start camera on resume
}
}
Also remove all these objects
private SurfaceView mySurfaceView;
private Camera mCamera;
private CameraPreview mPreview;
No need for them ,it's there in your zXingScannerView.

Actually you are not release objects when switch to other fragment first release all object in onPause() method and onResume() reconnect with camera. try this one :
#Override
public void onResume() {
super.onResume();
if (zXingScannerView!= null) {
zXingScannerView.stopCameraPreview();
zXingScannerView.resumeCameraPreview(this);
}
}

Changing to Landscape crashes my Android app

I am developing an app and want users to be able to use their phones horizontally or vertically, however, if I start in portrait and switch to landscape, the app crashes. It also crashes if I start landscape and switch to portrait.
Here is my AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

Hii for working in landscape and portrait mode, you have to use saved instance and restore saved instance or else your application values
googleApiClient,lastLocation,zip,user values may have null value and causes this issue
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
// Save UI state changes to the savedInstanceState.
// This bundle will be passed to onCreate if the process is
// killed and restarted.
savedInstanceState.putBoolean("MyBoolean", true);
savedInstanceState.putDouble("myDouble", 1.9);
savedInstanceState.putInt("MyInt", 1);
savedInstanceState.putString("MyString", "Welcome back to Android");
savedInstanceState.putParcelable("parcelable", "");
savedInstanceState.putSerializable("serializable", "");
}
The Bundle is essentially a way of storing a NVP ("Name-Value Pair") map, and it will get passed in to onCreate() and also onRestoreInstanceState() where you'd extract the values like this:
#Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Restore UI state from the savedInstanceState.
// This bundle has also been passed to onCreate.
boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
double myDouble = savedInstanceState.getDouble("myDouble");
int myInt = savedInstanceState.getInt("MyInt");
String myString = savedInstanceState.getString("MyString");
}

Calling function from a Fragment ..No activity to handle error

I saw many question related to this one but none solved my problem yet so I apologize if it was duplicated.
I'm creating a contact book. I've created a fragment to display all contacts.
Now what I want to do is to created an imageview (Call Button) to enable calling the contact when clicked.
I keep getting the error (No Activity found to handle Intent { act android.intent.action.CALL }and when I run on my device it crashed although I've added the intent to the manifest.
What am I doing wrong ?

Notification does not open the fragment?

I created a Notification and I want it to open a Fragment when clicked. It works in general, but when I have another Fragment open in my application at the time, it does not work.
For example, I have two Fragments: NoticiaFrag and EventoFrag. If I open my application and open the NoticiaFrag after pressing the home button of the device to minimize the application and receiving a notification to EventoFrag, when I click the notification opens NoticiaFrag and not EventoFrag.
To make this work I need close the application with the back button. After the application closes it works fine. I think I need to reopen the application when I click the Notification, but I don't know how.
The method that opens the Fragments from the Notification is in CustomDrawerLayout and called openFrag().
How can I solve this issue?
Notification
public class SendNotification {
public SendNotification(Context context, String title, String tickerText, String message, String url) {
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent;
Intent intent = new Intent(context, CustomDrawerLayout.class);
Bundle bd = new Bundle();
bd.putString("url", url);
intent.putExtras(bd);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.logo)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setTicker(tickerText)
.setContentTitle(title)
.setShowWhen(true)
.setWhen(System.currentTimeMillis())
.setContentText(message);
mBuilder.setContentIntent(contentIntent);
Notification notification = mBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.vibrate = new long[]{150, 300, 150, 600};
mNotificationManager.notify(AndroidSystemUtil.randInt(), notification);
}

Manifest
<activity android:name=".menu.CustomDrawerLayout" android:launchMode="singleTop"/>

The problem is that Android by default doesn't deliver a new Intent to an Activity that is already running. If you close your app via the back button, the Activity is destroyed and the next time startActivity() is called a new instance is created and the new Intent delivered. If you leave the Activity via the home button, the Activity is not destroyed. When you call startActivity() in this case, the already running instance of the Activity is brought to the foreground, but a new Intent is not delivered.
To change this behaviour you can define your activity in the manifest with launchMode="singleTop":
<activity
...
android:launchMode="singleTop"
...
>
</activity>
In this case Android will deliver a new Intent via onNewIntent(), which you can override:
This is called for activities that set launchMode to "singleTop" in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent). In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.
Just noticed the flags you're passing into your Intent. In that case you probably just have to override onNewIntent() in your Activity.
I've run into this problem myself before and asked a question here. There's some more background in that question, the accepted answer, and the comments.
