WebView videos on fullscreen

Please see below my code: I have tried several codes that fulllscreen for videos and I did not succeed, or I did not know how to install.
I need enable fullscreen for videos for any player video

wv.loadUrl("https://www.mfshd.net");
wv.setWebViewClient(new MobWebViewClient());
}
#Override
public void onBackPressed() {

wv.goBack();

super.onBackPressed();

// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class MobWebViewClient extends WebViewClient {
}
}

Firstly you have to add a FrameLayout in your activity_main and make its visibility "gone"
Secondly add this code to your MainActivity:
private View mCustomView;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
wv.setWebChromeClient(new WebChromeClient() {
#Override
public void onShowCustomView(View view, CustomViewCallback callback) {
super.onShowCustomView(view, callback);
// if a view already exists then immediately terminate the new one
if (mCustomView != null) {
callback.onCustomViewHidden();
return;
}
mCustomView = view;
wv.setVisibility(View.GONE);
frameLayout.setVisibility(View.VISIBLE);
frameLayout.addView(view);
mCustomViewCallback = callback;
}
#Override
public void onHideCustomView() {
super.onHideCustomView();
if (mCustomView == null)
return;
wv.setVisibility(View.VISIBLE);
frameLayout.setVisibility(View.GONE);
// Hide the custom view.
mCustomView.setVisibility(View.GONE);
// Remove the custom view from its container.
frameLayout.removeView(mCustomView);
mCustomViewCallback.onCustomViewHidden();
mCustomView = null;
}
});

Android Studio app crashes when i try to test it

The app crashes when i tried to test, i am using fragments to create the app:
App crashed
I have this in audioFragment.java:
package amaguenet.com.reproductorxassidas;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
import android.media.MediaPlayer;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class audioFragment extends Fragment {
// variable declaration
private ListView mainList;
private MediaPlayer mp;
private final String[] listContent = {"Ahonzubilahi Min Mayli", "Ajabani Khayru Baqin", "Ajabani Rabbu Sama", "Ala Innani Usni",

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_audio, container, false);
// Initializing variables
mp = new MediaPlayer();
mainList = (ListView) v.findViewById(R.id.listView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, listContent);
mainList.setAdapter(adapter);
mainList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view,
int position, long id) {
playSong(position);
}
});
return v;
}
public void playSong(int songIndex) {
// Play song
mp.reset();// stops any current playing song
mp = MediaPlayer.create(getActivity().getApplicationContext(), resID[songIndex]);// create's
// new
// mediaplayer
// with
// song.
mp.start(); // starting mediaplayer
}
#Override
public void onDestroy() {
super.onDestroy();
mp.release();
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public interface OnFragmentInteractionListener {
}
}
And this in a in fragment_audio (the layout):
<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="amaguenet.com.reproductorxassidas.audioFragment"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" >
</ListView>
</RelativeLayout>
Can some helps with this, i am using Fragments in Android Studio?

You can use getIdentifier() method, here is a simple example:
private final int resID = getContext().getResources().getIdentifier(direction, "raw", PACKAGE_NAME);
direction - string with your file name f.e: "ahonzu_bilahi_min_mayli"
PACKAGE_NAME - is your package name

Sendind data from one activity to another

Hi i'm new here and firstly i want to apologise for my language .I wanted to create my first android app ,and im curently struggle with some issues.
MainActivity ,which represents my main screen containing two buttons and spinner.In spinner user can choose one text file and after selection spinnerActivity should be triggered(screen with opened text file).I found problem because not every record from spinner trigger activity with text file that i want (one trigger file that i want and other trigger screen with empty TextView). Here is layout of spinnerActivity
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"

<LinearLayout
android:layout_width="fill_parent"

Can someone look at this and help me with finding bugs?Thanks

Position starts form 0, I think problem is with the conditions,
You can write like this-
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Intent intent = new Intent(MainActivity.this, SpinnerActivity.class);
intent.putExtra("txt", pos + 1);
startActivity(intent);
}

OnLongClickListener - not getting fired + android

I have this OnLongClickListener which is not getting fired. I think I have setup everything correctly and it has worked with a contextmenu before but right now it's not firing and the log is not even giving me any error.
I really hope you can give me any ideas. It is probably a silly mistake somewhere.

Here is the xml file where I have my ListView:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/mainListView"
android:longClickable="true"
android:clickable="true"
></ListView>
</LinearLayout>

You are attaching a listener to the entire view instead of each row. I'm not sure why nothing is being fired, but those touch events are probably being intercepted by other views.
Instead of ListView.setOnLongClickListener(), you should use ListView.setOnItemLongClickListener().
Here is the link for the Android Docs for this method.

Since you are registerForContextMenu for your listview already. setOnLongClickListener is not longer needed. What you needs is onCreateContextMenu method and onContextItemSelected.
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo){
// create menu item here
}
#Override
public boolean onContextItemSelected(MenuItem item){
// do your long click listener here
}

Can someone show me a simple working implementation of PagerSlidingTabStrip?

Here is the library: https://github.com/astuetz/PagerSlidingTabStrip
I'm trying to implement it but my app keeps crashing on startup. I've tried to understand the sample app that is posted but don't think I'm doing something right. Here is my code:
MainActivity.java
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.LayerDrawable;
import android.graphics.drawable.TransitionDrawable;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.util.TypedValue;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import com.astuetz.PagerSlidingTabStrip;
public class MainActivity extends FragmentActivity {
private final Handler handler = new Handler();
private PagerSlidingTabStrip tabs;
private ViewPager pager;
private MyPagerAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new MyPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
tabs.setViewPager(pager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override

super.onSaveInstanceState(outState);
}
#Override

}
private Drawable.Callback drawableCallback = new Drawable.Callback() {
#Override
public void invalidateDrawable(Drawable who) {
getActionBar().setBackgroundDrawable(who);
}
#Override
public void scheduleDrawable(Drawable who, Runnable what, long when) {
handler.postAtTime(what, when);
}
#Override
public void unscheduleDrawable(Drawable who, Runnable what) {
handler.removeCallbacks(what);
}
};
public class MyPagerAdapter extends FragmentPagerAdapter{
private final String[] TITLES = {"T1","T2"};
public MyPagerAdapter(FragmentManager fm){
super(fm);
}
public CharSequence getPageTitle(int position){
return TITLES[position];
}
#Override
public Fragment getItem(int i) {
return null;
}
#Override
public int getCount() {
return TITLES.length;
}
}
}
And here is activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

You're not instantiating any of the fragments you wish to become tabs in the FragmentPagerAdapter, getItem method. Instead you're returning null and therefore there are no views to fill the viewpager. I can see you've checked out his sample project, maybe take a closer look at the fragments you're trying to add to the viewpager. The above answer looks like a sound implementation.

Here is an example that I am using right now,
public class Formulario extends FragmentActivity implements ActionBar.TabListener {
private static final FragmentTransaction transaction = null;
public String ambitorec;
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "tab 1", "tab 2", "tab 3" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_formulario);
ambitorec = getIntent().getStringExtra("ambito");
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
also you need to add the adapter, in this case :
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// tab 1 fragment activity
return new Formulario1Fragment();
case 1:
// tab2 fragment activity
return new Formulario2Fragment();
case 2:
// tab 3 fragment activity
return new MultimediaFragment();
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
hope it helps, if you need more help ill try to explain

In FragmentPagerAdapter#getItem, you are not instantiating any of the fragments you want to become tabs. Instead of returning a fragment, you're returning null, which means there are no views to fill the viewpager. I see you've looked over his sample project, so look over the fragments you're trying to add to the viewpager again. The above response appears to be a second implementation.
