I am doing a project that requires me to change an image in the same form content page with a button onclick or another button method if you have one. I normally program in C# with visual studio and I am not used to the java so I would greatly appreciate it, Thank you.
Here is a sample image changer code

thank you
If those CardView will contain different data you can use a RecyclerView and on button click you can add an item in the list and notify the adapter this will add a new item(here item is your CardView created in a different XML file) on screen.
This could be helpful
and this too
I have this xml file where there are 4 image views, with one logo at the centre and the other three are just circles with radius greater than the previous one surrounding the logo. I want to display this as an animation until my page gets loaded. In want that the three circles appear one after the other in loop in a sequence. How can I do that ?

I have also attached a picture for a better visualization if needed :

#Srijan,
There are more ways to achieve this.
Please refer to objectAnimator or animation-list drawable for more details.
As a quick answer to your problem, please see the below sample code.
package com.jrh.testanim;
import androidx.appcompat.app.AppCompatActivity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.os.Handler;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
int count= 0;
int imgArr[] = new int[]{
R.drawable.circle1,
R.drawable.circle2,
R.drawable.circle3,
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView imageView = (ImageView) findViewById(R.id.animation_imageview);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
imageView.setImageResource(imgArr[count]);
handler.postDelayed(this, 500);
count++;
if (count > 2) {
count = 0;
}
}
}, 500);
}
}
Please check this and mark accepted, if it solves your problem.
Thanks

I want to make a ListView, when you long click on an item, the item will be added to the buttons: delete and update (only the clicked item):
So I have made a ListView in my MainLayout:
<ListView
android:id="#+id/neighborhood"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginBottom="8dp"
app:layout_constraintBottom_toTopOf="#+id/allAddresses"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/AddresSearch" />
and a Custom ListView Item lay out, which contains 3 TextViews:
<android.support.constraint.ConstraintLayout 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:id="#+id/button_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".passItemView">
<TextView
android:id="#+id/num"
android:layout_width="86dp"
android:layout_height="45dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="28dp"
android:text="cv"
app:layout_constraintEnd_toStartOf="#+id/house"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/house"
android:layout_width="86dp"
android:layout_height="45dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="32dp"
android:text="cvc"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/pass"
android:layout_width="86dp"
android:layout_height="45dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="32dp"
android:text="cv"
app:layout_constraintEnd_toStartOf="#+id/num"
app:layout_constraintTop_toTopOf="parent" />
and this layout is conneted to a class "passItemView", and there, what I did is that on longClick on the layout it will add 2 button (or even just will make a toast)
But it does nothing.
public class passItemView extends AppCompatActivity {
Button delete = new Button(this);
Button update = new Button(this);
ConstraintLayout btnLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pass_item_view);
btnLayout = (ConstraintLayout) findViewById(R.id.button_layout);
btnLayout.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Toast.makeText(passItemView.this,"Toast it",Toast.LENGTH_LONG).show();
btnLayout.addView((delete));
btnLayout.addView((update));
return false;
}
});
Thank you for your Help.
use an boolean value (ex : showButtons) and initialize set it false for all items.
when you clicked someitem make items showButtons variable true and notifydatasetchange (reload lsitview) again.
I was playing around with the Shared Element Transition and developed a testapp with 4 Fragments.
In the picture you can see, the first Fragment contains a "start now" message, when it's clicked I want to replace the container with the Fragment in the middle. As an eye candy I want an Animation by using Shared Element Transitions.
Problem
My Problem is, if I leave the first Fragment empty (without starting message) and I for example set the OnClickListener to the Icon itself, everything is working alright with a nice animation. But if the first Fragment has that message in it only the first Icon (the second Fragment, picture in mid) doesn't have an animation anymore. It's just replacing the first fragment. The curios thing is, if I change my OnClickListener and let it start the second page (right picture) the animation is working fine again. So only the first/left Icon does not provide an animation though all Methods and XML are mostly 1:1 the same.
As I couldn't develope a better solution, each "toolbar" is designed in the Fragment itself.
Main Activity
public class FirstStartupActivity extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_firststartup);
doFragmentTransaction(new MainFragment(), "TAG", false, null);
}
public void doFragmentTransaction(Fragment fragment, String tag, boolean addToBackStack, List<View> sharedElements){
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.ActivityFirstStartup_fragmentContainer, fragment, tag);
if(addToBackStack){
transaction.addToBackStack(tag);
}
if( sharedElements != null && !sharedElements.isEmpty()){
for(int i = 0; i < sharedElements.size(); i++){
View view = sharedElements.get(i);
transaction.addSharedElement(view, view.getTransitionName());
}
}
transaction.commit();
}}
First Fragment with Message
public class MainFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_firststartup_home, container, false);
View view = v.findViewById(R.id.relLayoutPageOne);
final List<View> listview = new ArrayList<>();
listview.add(view);
View view2 = v.findViewById(R.id.relLayoutPageTwo);
final List<View> listview2 = new ArrayList<>();
listview2.add(view2);
Button button = v.findViewById(R.id.buttonStart);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
((FirstStartupActivity)getActivity()).doFragmentTransaction(new UsernameFragment(), "test", true, listview);
//((FirstStartupActivity)getActivity()).doFragmentTransaction(new CameraFragment(), "TEST2", true, listview2);
}
});
RelativeLayout rel2 = v.findViewById(R.id.relLayoutPageTwo);
rel2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
((FirstStartupActivity)getActivity()).doFragmentTransaction(new CameraFragment(), "TEST2", true, listview2);
}
});
return v;
}}
Second Fragment No Animation
public class UsernameFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_firststartup_pgone, container, false);
postponeEnterTransition();
return v;
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
setSharedElementEnterTransition(TransitionInflater.from(getContext()).inflateTransition(android.R.transition.move));
}
}}
Third Fragment Working
public class CameraFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_firststartup_pgtwo, container, false);
return v;
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
setSharedElementEnterTransition(TransitionInflater.from(getContext()).inflateTransition(android.R.transition.move));
}
}}
Second Fragment (Picture in middle) No Animation when replacing)

Visual Description
First Icon doesn't work but the second one works like charm
For some Reason the first GIF is way too fast, its popping up normally the only Problem is the missing Animation
Well I tried to change some things and I made everything worse. Then I "repaired" it and now it works, unfortunetly I can't show you a solution for that. I try to work through the codes again
EDIT: #LieForBanana had the solution but I understood him wrong, indeed my first Fragment also had the Transition Name it (3x TransitionName ProfilePic). I am ashamed, it was just one silly mistake
I am trying to run a simple app which displays an image with Animation on button click.All I see is a white screen.I am using exact code from the tutorial.Can any one tell me whats the problem?
This is the tutorial https://www.tutorialspoint.com/android/android_imageswitcher.htm
This is MainActivity.java
import...
public class MainActivity extends AppCompatActivity {
ImageSwitcher imageSwitcher;
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageSwitcher=(ImageSwitcher)findViewById(R.id.img);
btn=(Button)findViewById(R.id.button);
imageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
#Override
public View makeView() {
ImageView view = new ImageView(getApplicationContext());
view.setScaleType(ImageView.ScaleType.CENTER);
view.setLayoutParams(new
ImageSwitcher.LayoutParams(ActionBar.LayoutParams.WRAP_CONTENT,
ActionBar.LayoutParams.WRAP_CONTENT));
return view;
}
});
Animation in = AnimationUtils.loadAnimation(this,android.R.anim.slide_in_left);
Animation out = AnimationUtils.loadAnimation(this,android.R.anim.slide_out_right);
imageSwitcher.setInAnimation(in);
imageSwitcher.setOutAnimation(out);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "s", Toast.LENGTH_SHORT).show();
imageSwitcher.setImageResource(R.drawable.m1);
}
});
}
}
