Android playing sounds from a fragment

Android playing sounds from a fragment - java

I've found multiple similar posts but have been unable to resolve so posting my code for help.
I have 3 fragments that use a ViewPager with a PagerAdapter to allow for swiping between fragments. This project started with no fragments and I was able to play sounds from buttons clicked all from MainActivity.
Here's the code that worked.
MainActivity
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
MediaPlayer example1Sound;
MediaPlayer example2Sound;
MediaPlayer example3Sound;
MediaPlayer example4Sound;
MediaPlayer example5Sound;
MediaPlayer example6Sound;
MediaPlayer example7Sound;
MediaPlayer example8Sound;
MediaPlayer example9Sound;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
example1Sound = MediaPlayer.create(this, R.raw.example1);
example2Sound = MediaPlayer.create(this, R.raw.example2);
example3Sound = MediaPlayer.create(this, R.raw.example3);
example4Sound = MediaPlayer.create(this, R.raw.example4);
example5Sound = MediaPlayer.create(this, R.raw.example5);
example6Sound = MediaPlayer.create(this, R.raw.example6);
example7Sound = MediaPlayer.create(this, R.raw.example7);
example8Sound = MediaPlayer.create(this, R.raw.example8);
example9Sound = MediaPlayer.create(this, R.raw.example9);
}
public void playExampleSound1(View view) {
example1Sound.start();
}
public void playExampleSound2(View view) {
example2Sound.start();
}
public void playExampleSound3(View view) {
example3Sound.start();
}
public void playExampleSound4(View view) {
example4Sound.start();
}
public void playExampleSound5(View view) {
example5Sound.start();
}
public void playExampleSound6(View view) {
example6Sound.start();
}
public void playExampleSound7(View view) {
example7Sound.start();
}
public void playExampleSound8(View view) {
example8Sound.start();
}
public void playExampleSound9(View view) {
example9Sound.start();
}
}

I know it's not pretty. Should have made an array but nevertheless it worked.
So here's my problem. Using the same ideology I tied the same thing with fragment.
MainActivity.java
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
public class MainActivity extends FragmentActivity {
ViewPager viewpager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpager = (ViewPager)findViewById(R.id.pager);
PagerAdapter padapter = new PagerAdapter(getSupportFragmentManager());
viewpager.setAdapter(padapter);
}
}
PagerAdapter.java
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class PagerAdapter extends FragmentPagerAdapter{
public PagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new FragmentOne();
case 1:
return new FragmentTwo();
case 2:
return new FragmentThree();
default:
break;
}
return null;
}
#Override
public int getCount() {
return 3;
}
}

return inflater.inflate(R.layout.fragment_one_layout,container,false);

Clicking on imagebutton crashes the app. I know the MediaPlayer can work inside the app because I tested inserting example1Sound.start(); like this...
Snippet from FragmentOne.java
example1Sound = MediaPlayer.create(this.getActivity(), R.raw.example1);
example2Sound = MediaPlayer.create(this.getActivity(), R.raw.example2);
example3Sound = MediaPlayer.create(this.getActivity(), R.raw.example3);
example1Sound.start();
The sound plays when the fragment loads. How do I get the onclick to work?

You can use onClickListeners for each button, it works.
I think, fragnment_one_layout.xml is linked to FragmentOne.java using inflater
but the fragnment_one_layout.xml has no access to FragmentOne.java , and hence
the statement onClick="methodName" is not able to access the desired method.
mediaPlayer object has no connection with your problem.

You can make one function that redirect sound from Activity to Fragment!
in Activity
fun onSound(sound:Int){
mp = MediaPlayer.create(this,soundFile)
mp.start
}
from fragment
onResume{
(activity as ActivityName).onSound(R.raw.sound)
}

How can my buttons be visible after adding a new code?

my code works well, with 2 buttons ("home" and "chiudi") at the bottom, but I wanted to add more code to my webview app, and this new code hides my buttons.
This is the new code I want to add:
...
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView wView, String url)
{
if (url.startsWith("mailto:") || url.startsWith("tel:") || url.startsWith("geo:") ||
url.startsWith("http:") || url.startsWith("https:")) {
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse(url));
startActivity(intent);
return true;
} else if (url.startsWith("whatsapp:")) {
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
return true;
} else if (url.startsWith("spotify:")) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(
"spotify:album:0sNOF9WDwhWunNAHPD3Baj"));
intent.putExtra(Intent.EXTRA_REFERRER,
Uri.parse("android-app://" + context.getPackageName()));
startActivity(intent);
return true;
}
return false;
}
});
...
And this is my code:

Your alignment of views is not correct and In ConstraintLayout you have arranged your views by giving reference to other views. It would be good to check this link for a better understanding of how to use ConstraintLayout.

Android App - Clicking on Button does not open new activity

My problem is as follows: I have an activity activity transport. On this activity I have one button Auto which should open the new activity: activity_auto. Whenever I click on this button the first activity activity transport opens again. No errors are shown and the references are okay, I think.
I attached my code snippet
Class: activity_transport
package com.group6.travlhoe;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
public class activity_transport extends AppCompatActivity implements View.OnClickListener {
Button btnAuto;
private BottomNavigationView bottomNavigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_transport);
btnAuto = (Button) findViewById(R.id.Auto);
btnAuto.setOnClickListener(this);
bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottomNavigationView);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener(){
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item){
if (item.getItemId()==R.id.menu_start){
startActivity(new Intent(activity_transport.this, MainActivity.class));
} else if(item.getItemId()==R.id.menu_allgemein){
startActivity(new Intent(activity_transport.this, activity_allgemein.class));
} else if(item.getItemId()==R.id.menu_transport){
startActivity(new Intent(activity_transport.this, activity_transport.class));
} else if(item.getItemId()==R.id.menu_rechnung){
startActivity(new Intent(activity_transport.this, activity_rechnung.class));
} else if(item.getItemId()==R.id.menu_unterkunft){
startActivity(new Intent(activity_transport.this, activity_unterkunft.class));
}
return true;
}
});
bottomNavigationView.setSelectedItemId(R.id.menu_transport);
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.Auto) {
startActivity(new Intent(activity_transport.this, activity_auto.class));
}
}
}

try this
Intent it=new Intent(getApplicationContext(),activity_auto.class);
startActivity(it)
You may also try
getBaseContext()
If none works use
activity_transport.this.startActivity
instead of
startActivity

You need to add a Listener.Try out the code below
btnAuto.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (v.getId() == R.id.Auto) {
startActivity(new Intent(activity_transport.this, activity_auto.class));
}
}
});

Fragments not showing content on viewPager scroll - Android

I'm new to Android..
I am trying to create a simple application with a sliding tab to scroll between 2 fragments. The fragments are populated with dummy buttons just to see if the scrolling works. However when I run all I see are the viewPager indexes on top without the fragments. I am also using these two files SlidingTabLayout.java and SlidingTabStrip.java that are given by Android. Here are my classes:
MyFragmentPagerAdapter.java
package billdozer.com.testxml;
import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class MyFragmentPagerAdapter extends FragmentPagerAdapter {
// Holds tab titles
private String tabTitles[] = new String[] { "Frag #1", "Frag #2"};
private Context context;
public MyFragmentPagerAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
#Override
public int getCount() {
return 2;
}
// Return the correct Fragment based on index
#Override
public Fragment getItem(int position) {
if(position == 0){
return new TabFragment1();
} else if(position == 1) {
return new TabFragment2();
}
return null;
}
#Override
public CharSequence getPageTitle(int position) {
// Return the tab title to SlidingTabLayout
return tabTitles[position];
}
}

SharedElementTransition on fragment dont work

I want to add shared element transition to items in a recyclerview which will opened on another fragment, but nothing works.
The only view that i want to share is an ImageView.
ImageViews and Textviews inside recyclerview items are loaded using Glide for images and firebase database methods for texts. In the detailed fragment, the bitmap of recyclerview item is passed and only the text is downloaded again.
the method which opens the new fragment from recyclerview items is :
homeUserAnnouncesAdapter.setOnCardAnnounceClickedListener(new OnCardAnnounceClickedListener() {
#Override
public void onCardClicked(CardRentAnnounce card, ImageView imageView, int poz) {
Log.v("TRANSITIONTEST", "CLICKED FROM HOME FRAGMENT --- RENT");
Log.v("TRANSITIONTEST", "in onClick: " + imageView.getTransitionName());
Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
OpenRentAnnounceFragment newFragment = OpenRentAnnounceFragment.newInstanceWithImage(card, bitmap, poz);
newFragment.setSharedElementEnterTransition(new DetailsTransition());
newFragment.setEnterTransition(new Fade());
newFragment.setExitTransition(new Fade());
newFragment.setSharedElementReturnTransition(new DetailsTransition());
getActivity().getSupportFragmentManager()
.beginTransaction()
.addSharedElement(imageView, imageView.getTransitionName())
.replace(R.id.content_main_without_toolbar, newFragment)
.addToBackStack(null)
.commit();
}
});
the DetailsTransition class is :
public class DetailsTransition extends TransitionSet{
public DetailsTransition() {
init();
}
/**
* This constructor allows us to use this transition in XML
*/
public DetailsTransition(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
setOrdering(ORDERING_TOGETHER);
addTransition(new ChangeBounds())
.addTransition(new ChangeTransform())
.addTransition(new ChangeImageTransform());
}
}
i'm assigning different transition names for every view, on adapter:
#Override
public void onBindViewHolder(final HomeUserAnnouncesViewHolder holder, int position) {
final CardRentAnnounce cardRentAnnounce = cardRentAnnounceArrayList.get(position);
holder.updateUI(cardRentAnnounce);
ViewCompat.setTransitionName(holder.rentImage, String.valueOf(position) + "_rent");
MaterialRippleLayout mlr = (MaterialRippleLayout)holder.itemView.findViewById(R.id.search_home_ripple);
mlr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(listener != null){
listener.onCardClicked(cardRentAnnounce, holder.rentImage, holder.getAdapterPosition());
}
}
});
}
the id of image in recyclerview item is identically with the image in fragment
i have followed this tutorial to create the transition, even cloned the project to my pc, run on emulator and trying to do exactly like in the working project but still not working.
how i set the image and imageTransition name in new fragment :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_open_rent_announce, container, false);
rootView = view;
image = (ImageView)view.findViewById(R.id.detailed_image);
image.setImageBitmap(currentImageBitmap);
image.setTransitionName(String.valueOf(pozition) + "_rent");
Log.v("TRANSITIONTEST", "in onCreateView: " + image.getTransitionName());
initViews(view);
setViews();
return view;
}
Fragment SharedElementsTransition tutorial
both images on recyclerview and detailed fragment are loaded with Glide, but i've tried with local images and still no succes.
What did i'm missing? ask for more code if needed.
Thanks.
