TextView Edit Text is not responding to Click Events

I have a layout with three TextViews, two TextViews are responding to Click Events but the last one is not responding. I am using Navigation to navigate to other fragments. The OnClick method is called inside an adapter which implements view.OnClickListener.

I have tried multiple ways, rechecked id's as well but nothing is working.

as #Nilesh Rathod said, you need to make sure that all your text view have set an on click listener like:
textView.setOnClickListener(this);
or you can also:
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Here you put the code you want to use for the specific textView click event
}
});

How can I change an image using a button in android studio?

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

Changing a Item in a listView on a click

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.

Animate LayoutChanges does not work properly

I want to animate text in my textswitcher. I went through all the stack questions and the documentation, but they didn't solve my problem.
Here is my XML:

Here is my code
public class Main3Activity extends AppCompatActivity {
private TextSwitcher mSwitcher;
Button btnNext;
int currentIndex=-1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
Resources resources = getApplicationContext().getResources();
final String[] textString = resources.getStringArray(R.array.teacher_messages);
btnNext = findViewById(R.id.button);
mSwitcher = findViewById(R.id.tv__inc_pre_sing__teacher_message);
mSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
public View makeView() {
// TODO Auto-generated method stub
// create new textView and set the properties like clolr, size etc
TextView myText = new TextView(Main3Activity.this);
myText.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
myText.setTextColor(Color.BLUE);
return myText;
}
});
// Declare the in and out animations and initialize them
Animation in = AnimationUtils.loadAnimation(this,android.R.anim.slide_in_left);
Animation out = AnimationUtils.loadAnimation(this,android.R.anim.slide_out_right);
// set the animation type of textSwitcher
mSwitcher.setInAnimation(in);
mSwitcher.setOutAnimation(out);
// ClickListener for NEXT button
// When clicked on Button TextSwitcher will switch between texts
// The current Text will go OUT and next text will come in with specified animation
btnNext.setOnClickListener(new View.OnClickListener() {
//
public void onClick(View v) {
// TODO Auto-generated method stub
currentIndex++;
// If index reaches maximum reset it
if(currentIndex==textString.length)
currentIndex=0;
mSwitcher.setText(textString[currentIndex]);
((ViewGroup) findViewById(R.id.rl__inc_pre_sing__tm_container)).getLayoutTransition()
.enableTransitionType(LayoutTransition.CHANGING);
}
});
}
}
The animation on ConstraintLayout whose id is rl__inc_pre_sing__tm_container does not work properly. Suppose my TextSwitcher has text whose length is greater than 3 and then TextSwitcher shows text whose length is 1 then the ConstraintLayout does not animate, if the next text is of length 1 then the constraintlayout animates.
I am not able to figure out this weird behaviour.

Here is the issue: When the TextSwitcher transitions from X lines of text to something less than X lines then the TextSwitcher's height does not change.
The TextSwitcher inherits some behavior from ViewAnimator which considers the height of all views when determining the height of the widget. The solution is to add the following XML to the TextSwitcher definition in the layout file that will inhibit this behavior:
android:measureAllChildren="false"
Thanks to this Stack Overflow answer that states all this better than I have.

ImageSwitcher now showing image

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);
}
});
}
}
