Opening the last fragment view in Java Android Apps

I created a bottom navigation for my app and was wondering how could I make it so when the user opens the app, it returns to the last fragment they were viewing? At the moment even if you just switch apps for a second, it reverts to the home page immediately. Thanks in advance!
import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.Fragment;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.MenuItem;
import com.google.android.material.bottomnavigation.BottomNavigationView;
public class MainActivity extends AppCompatActivity {
MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView bottomnav = findViewById(R.id.bottom_menu);
bottomnav.setOnNavigationItemSelectedListener(navListener);
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_layout, new HomeFragment()).commit();
mediaPlayer = MediaPlayer.create(this, R.raw.clickandboop);
}
private final BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
Fragment selectedFragment = null;
switch (menuItem.getItemId()) {
case R.id.nav_home:
selectedFragment = new HomeFragment();
mediaPlayer.start();
break;
case R.id.nav_favourites:
selectedFragment = new FavFragment();
mediaPlayer.start();
break;
case R.id.nav_trophies:
selectedFragment = new TrophiesFragment();
mediaPlayer.start();
break;
case R.id.nav_info:
selectedFragment = new InfoFragment();
mediaPlayer.start();
break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_layout, selectedFragment).commit();
return true;
}
};

Fragments already restore you back to exactly where you were.
This means that you need to wrap your replace() call with a check of savedInstanceState == null to avoid destroying the just recreated Fragment:
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_layout, new HomeFragment())
.commit();
}

Just use sharedprefs and store the last fragment that the user was in. Use the onStop callback of the fragment to store it.
When the user opens the application just check this value if it's not set open homefragment otherwise just open the last fragment based on the value you have in your shared preferences

onClick method not found

I'm new to this and i'm doing an app for a university project and I wanted to put a VideoView in my app, so I watched this video ("https://www.youtube.com/watch?v=SrPHLj_q_OQ&t=421s") and did it and worked. But then I add to copy the code from content_main.xml to a fragment and it stopped working and giving an error on the "android:onClick" on the Button. And when I press CTRL+F1 to inspect it says this:
"Corresponding method handler'public void videoplay(android.view.View)' not found
Inspection info:The onClick attribute value should be the name of a method in this View's context to invoke when the view is clicked.This name must correspond to a public method that takes exactly one parameter of type View.
Must be a string value, using '\;' to escape characters such as '\n' or '\uxxxx' for a unicode character.

Heres my InicioFragment java:
package intro.android.migueloliveiraapp;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class InicioFragment extends Fragment {

// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_inicio, container, false);
}
}
heres my updated InicioFragment.java:
package intro.android.migueloliveiraapp;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.net.Uri;
import android.widget.Button;
import android.widget.VideoView;
/**

public class InicioFragment extends Fragment {
public InicioFragment() {
// Required empty public constructor
}
#Override
public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_inicio, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
clk = (Button) view.findViewById(R.id.button);
videov = (VideoView) view.findViewById(R.id.videoView);
// bind the views here.
Button button2 = view.findViewById(R.id.button);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something here.
}
});
}
Button clk;
VideoView videov;
public void videoplay(View v){
String videopath = "android.resource://intro.android.migueloliveiraapp/" + R.raw.oliveira;
Uri uri = Uri.parse(videopath);
videov.setVideoURI(uri);
videov.start();
}
}

You can use this for click.
Button mPlayVideo;
//In oncreate
mPlayVideo = findViewById(R.id.button2);
mPlayVideo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Clicked", Toast.LENGTH_SHORT).show();
}
});

In your xml your tools:context=".InicioFragment refers to your fragment and not your activity.
Your method is found inside the activity and not the fragment class and this is why are getting this error.
You can check Call an activity method from a fragment
But I can recommend using the onClick attribute inside your activities and inside fragment use normal click listener:
View view = findViewById(R.id.viewId);
view .setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do something
}
});

This is because you created videoplay() method inside your MainActivity.java . You should put your videoplay() method into the InicioFragment.java as it is the corresponding file for the xml layout you have mentioned above.
Initialize your variables like bellow inside your onCreateView method on InicioFragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_inicio, container, false);
Button btn1 = view.findViewById(R.id.button_id);
.....
.....
return view;
}
public void videoplay(View v){
.........
.....
}

The following error:
"Corresponding method handler'public void videoplay(android.view.View)' not found
Inspection info:The onClick attribute value should be the name of a method in this View's context to invoke when the view is clicked.This name must correspond to a public method that takes exactly one parameter of type View.
Must be a string value, using '\;' to escape characters such as '\n' or '\uxxxx' for a unicode character.
Issue id:OnClick "
means that you forget to add the corresponding method in your Activity class when using android:onClick="videoplay" attribute. So, you need to add the following method to your activity:
public void videoplay(View v){
// do something here.
}
The most important part is, android:onClick tag is only working when you're using it inside the content layout of Activity.. So, android:onClick doesn't work when you're using it inside the fragment layout. You need to use the onClickListener instead.
You need to bind the view and add the onClickListener with something like this:
public class InicioFragment extends Fragment {
public InicioFragment() {}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_inicio, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
// bind the views here.
Button button2 = view.findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something here.
}
});
}
}

Pay attention on your xml file that this file's context is your InicioFragment (tools:context=".InicioFragment" )
Therefore, videoplay(View v) should be inside your InicioFragment class.
That's the reason why is not found. It won't search on your MainActivity.
public class InicioFragment extends Fragment {
public InicioFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.testclassfragment, container, false);
Button clk = (Button) view.findViewById(R.id.button);
VideoView videov = (VideoView) view.findViewById(R.id.videoView);
return view;
}
public void videoplay(View v){
String videopath = "android.resource://intro.android.migueloliveiraapp/" + R.raw.oliveira;
Uri uri = Uri.parse(videopath);
videov.setVideoURI(uri);
videov.start();
}
}
Since you also have a variable for your button another option is to do:
clk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("TESTING", "Clicked");
}
});

Adding multiple on click listeners for several buttons

How can you make it so that user can have several buttons with on click listeners. I tried it with 2 buttons, but it said that I had already defined the on-click listener so I could not make another on click listener as a result. The code I have so far is:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.View;
import android.widget.LinearLayout;
public class MainActivity extends AppCompatActivity {
private View btnRender;
private LinearLayout container;
private View btnRendered;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnRender = (View)findViewById(R.id.btn_render);
container = (LinearLayout)findViewById(R.id.fragment_layout);
btnRendered = (View) findViewById(R.id.btn_rendered);
//set event handling for button
btnRender.setOnClickListener(onClickListener());
}
private View.OnClickListener onClickListener() {
return new View.OnClickListener() {
#Override
public void onClick(View v) {
//replace fragment when clicked
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_layout, new PDFRenderFragment());
ft.commit();
//gone button after all
btnRender.setVisibility(View.GONE);
container.setVisibility(View.VISIBLE);
}
};
}
}
The btn_rendered is the other button that I want to set an on click listener for, but the software will not let me do this. Is it true that I need to set up a switch-case method for it to work?
I just tried out both codes and none of them seem to have doen the desired effect. Now whenever I click one of the buttons, the 2nd pdf always shows! (what I was using the button for)

You can handle like below.
btnRender.setOnClickListener(onClickListener());
btnRendered.setOnClickListener(onClickListener());
private View.OnClickListener onClickListener() {
return new View.OnClickListener() {
#Override
public void onClick(View v) {
switch(v.getId()){
case R.id.btn_render:
//replace fragment when clicked
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_layout, new PDFRenderFragment());
ft.commit();
//gone button after all
btnRender.setVisibility(View.GONE);
container.setVisibility(View.VISIBLE);
break;
case R.id.btn_rendered:
// your logic here
break;
}
}
};
}

You can use same method for second button too and use if/else condition for identify which button is click in that method.
like below code.
//set event handling for button
btnRender.setOnClickListener(onClickListener());
second_btn.setOnClickListener(onClickListener());
Your onClickListener Method.
private View.OnClickListener onClickListener() {
return new View.OnClickListener() {
#Override
public void onClick(View v) {
//replace fragment when clicked
if (v == btnRender) {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_layout, new PDFRenderFragment());
ft.commit();
//gone button after all
btnRender.setVisibility(View.GONE);
container.setVisibility(View.VISIBLE);
} else if (v == second_btn) {
//second button click code
}
}
};
}

setOnclickListener for a button help please

just getting started with Android development and I can't figure out why this won't work. Here is the error that I am getting (last line before bold block-quote):

Well, I tried your code in IDE and the problem - in provided sample - is in variable declaration:
private OnClickListener answerL = new OnClickListener(){
public void onClick(view v) {
Random token = random();
int tokenno = token.nextInt(10);
CharSequence ans = "";
switch(tokenno) {
case 0:ans=getString(R.string.msg0);break;
case 1: ans=getString(R.string.msg1);break;
case 2: ans=getString(R.string.msg2);break;
case 3: ans=getString(R.string.msg3);break;
case 4: ans=getString(R.string.msg4);break;
case 5: ans=getString(R.string.msg5);break;
case 6: ans=getString(R.string.msg6);break;
case 7: ans=getString(R.string.msg7);break;
case 8: ans=getString(R.string.msg8);break;
case 9: ans=getString(R.string.msg9);break;
case 10:ans=getString(R.string.msg10);break;
}
Context context = getApplicationContext();
Toast msg = Toast.makeText(context,ans,Toast.LENGTH_LONG);
msg.show();
}
}//here should be ';'
It occurs because View.OnClickListener has body with methods. If there were no methods (e.g. you created a
private class MyOnClickListener implements OnClickListener
(http://developer.android.com/reference/android/view/View.OnClickListener.html)
then it would be like that:
private MyOnClickListener answerL = new MyOnClickListener(); //<- semicolon here.
You can avoid such in future using autoformating tool (ctrl+shift+f as default in Eclipse/ADT and ctrl+alt+l (or something like that) in AndroidStudio) or declaring class fields strictly before/after methods.
Hope it helps)

just as it says you need to insert a semicolon there since you are declaring a field here. So this is how it should be
private OnClickListener answerL = new OnclickListener(){
public void onClick(view v) {
...............
}//onClick ends here
}; //OnClickListener ends here

OnclickListener is an interface and you are supposed to create its object like this:
private OnClickListener answerL = new OnclickListener(){
public void onClick(view v) {
//do stuffs here
}
};
Please notice the semi-colon at the end.

Android ImageView not showing in SherlockFragment

I'm trying to make an ImageView, in the Graphical view it shows up but when I run it on my device and the emulator the image doesn't show up. Here's my XML code.
<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" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:scaleType="fitXY"
android:src="#drawable/map_mockup" />
and here's my Fragment1 code (I am using Fragment1 as the Fragment to display this ImageView)
import com.actionbarsherlock.app.SherlockFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

public class Fragment1 extends SherlockFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1, container, false);

I've tried using Log.d and it shows that Fragment1 is being loaded. I'm stumped, I don't know what to do and am completely lost right here.
If it matters, the resolution for the PNG is 900x1429.

Two things I can think of.
First, I'm not sure if your layout code shows us the whole file or a snippet. If it's the whole file, you're missing a closing tag on the relativeLayout. If it's a snippet then ignore me.
Second, can you post the code for the Activity that you are adding this Fragment to?

Did you try to add the in the onCreateView instead of the xml?That would be the first thing I'd try.Btw I used the same tutorial as you did and consider yourself lucky,mine doesnt even show the image on my device -.-

Please would you try this:
ft.replace(android.R.id.content, fragment1, "frag1");
instead of
ft.replace(R.id.content_frame, fragment1);
?
If this doesn't change anything, I suggest you use Log.d to confirm that your fragment1 is actually being loaded.
Edit:
Good, then follow Arkan's line or reasoning or place a textview in your xml like this, to determine whether or not the xml is being loaded:
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="if you can see me the problem must be with my image"
/>
