ViewFlipper outAnimation is not working

ViewFlipper outAnimation is not working - android

I want to continuously show different text on text view which animates from left to right, waits on the center of the screen for 3 sec and animates outside of the screen and replaced by a new text which animates from left to right
I have included a textview inside a viewflipper.

setContentView(R.layout.activity_main6);
mViewFlipper = findViewById(R.id.view_flipper);

mViewFlipper.setInAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_in_left));
mViewFlipper.setOutAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_out_right));

final String[] textString = resources.getStringArray(R.array.teacher_messages);
new Thread() {
#Override

super.run();
try {
while (!isInterrupted()) {
Thread.sleep(3000);
runOnUiThread(() -> updateText(textString));
}
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
public void updateText(String[] strings) {
if (count >= strings.length) {
count = 0;
}
textView.setText(strings[count]);
count++;
}
}
I guess the outanimation does not work as the textview length changes and I want to animate the constraint layout according to the textview height.
Not sure if this is the right reason.
The outAnimation of the view flipper does not work.

That's not how ViewFlipper works . the View flipper will only animate the view added to it .
Here's an example :
<ViewFlipper
android:id="#+id/viewFlipper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/loading"
android:autoStart="true"
android:flipInterval="5000"
android:inAnimation="#android:anim/slide_in_left"
android:outAnimation="#android:anim/slide_out_right">
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/text1"
android:textColor="#color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/text3"
android:textColor="#color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/tex2"
android:textColor="#color/white"
android:textSize="18sp" />
</ViewFlipper>

If that does not suit your needs . you can take a look at this solution. (Animating text changes in a TextView)

Textviews are not showing on real device

When app works fine
When app not shows textviews(its finding a sensor. When cant find, giving info on textview like 'didnt found')
I created a pedometer app. It was working well on my emulator and my own android device. But when ı publish that app my friends said textviews are invisible. I examined that problem in code but didnt found a problem. Textviews are getting their text from sensor. Writing steps and calories, after some calculating. Why that problem showed up? What is the source of this problem? Why is this happening?

I think it's not one of programmatic issue and could be your listview went up to bottom on screen. You could research How to develop an android application for different device sizes. Visit here https://developer.android.com/training/multiscreen/screensizes

I found what is the problem. I was forgetting the add user permissions.
I Added to the Manifest.xml:
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>
onCreate Method:
if(ContextCompat.checkSelfPermission(this,
Manifest.permission.ACTIVITY_RECOGNITION) == PackageManager.PERMISSION_DENIED){
//ask for permission
requestPermissions(new String[]{Manifest.permission.ACTIVITY_RECOGNITION}, PHYISCAL_ACTIVITY);
}

Recycleview custom layout constraint are changing for each inflated view causing problems

I have a recyclerview that inflates data fetched from json.
The issue I am facing are design issues - sometimes the text is aligned correctly and the image is shown and sometimes the text is too long, causing what I think is for the image not to be shown.
here is my XML:
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/heroImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/heroTitle"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginEnd="16dp"
android:autoSizeMaxTextSize="25dp"
android:autoSizeMinTextSize="15dp"
android:text="Hero Title"
android:textSize="25dp"
android:textStyle="bold"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/heroDescription"
android:layout_width="200dp"

android:layout_height="wrap_content"
android:layout_marginStart="36dp"
android:layout_marginTop="24dp"
android:layout_marginEnd="16dp"

android:autoSizeMinTextSize="15dp"
android:text="TextView"
android:textAlignment="center"
android:textSize="18dp"

app:layout_constraintStart_toEndOf="#+id/heroImage"
app:layout_constraintTop_toBottomOf="#+id/heroTitle" />
</android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>
and here is my adapter:
public class HeroesAdapter extends RecyclerView.Adapter<HeroesAdapter.HeroesViewHolder> {
private List<Hero> heroList;
public HeroesAdapter(List<Hero> heroList) {
this.heroList = heroList;
}
#NonNull
#Override
public HeroesViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View rowView = LayoutInflater.from(parent.getContext()).inflate(R.layout.hero_cell, parent, false);
return new HeroesViewHolder(rowView);
}
#Override
public void onBindViewHolder(#NonNull HeroesViewHolder holder, int position) {
Hero currentHero = heroList.get(position);
String str = String.join(",", currentHero.abilities);
holder.heroTitle.setText(currentHero.title);
holder.heroAbilties.setText(str);
Picasso.get().load(currentHero.image).resize(500,500).into(holder.heroesImage);
}
#Override
public int getItemCount() {
return heroList.size();
}
public static class HeroesViewHolder extends RecyclerView.ViewHolder {
ImageView heroesImage;
TextView heroTitle;
TextView heroAbilties;
public HeroesViewHolder(#NonNull View itemView) {
super(itemView);
heroesImage = itemView.findViewById(R.id.heroImage);
heroTitle = itemView.findViewById(R.id.heroTitle);
heroAbilties = itemView.findViewById(R.id.heroDescription);
}
}
}
This is the result I am getting and this is the wanted result.
the issues I am facing are:
making each row have a clean design and act the same for all.
images are sometimes shown, sometimes not.
bottom view is "half in screen" and half out of screen.

By using LinearLayout you can design your hero_cell that will give you the desirable output. as I do it for now.

adding cardviews to scroll view dynamically, not showing

I am attempting to add card views to a scroll view dynamically. so I am adding these cardviews to a linear layout which is situated inside a scrollview in my xml. However when I press the fab button I don't see anything. I don't know why. Is it something to do with layoutparams?
This is my create.java
public class create extends AppCompatActivity {
Button button;
Context context;
CardView cardview;
LayoutParams layoutparams;
TextView textview;
LinearLayout linearLayout;
ScrollView scrollView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create);
button = (Button)findViewById(R.id.button);
context = getApplicationContext();
linearLayout = (LinearLayout) findViewById(R.id.linearlayout1);
scrollView = (ScrollView)findViewById(R.id.scrollView1);
//TODO FAB BUTTON
FloatingActionButton floatingActionButton =
(FloatingActionButton) findViewById(R.id.fab);
floatingActionButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
createCardViewProgrammatically();
}
});
}
public void createCardViewProgrammatically(){
CardView card = new CardView(context);
// Set the CardView layoutParams
LayoutParams params = new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT
);
card.setLayoutParams(params);
// Set CardView corner radius
card.setRadius(9);
// Set cardView content padding
card.setContentPadding(15, 15, 15, 15);
// Set a background color for CardView
card.setCardBackgroundColor(Color.parseColor("#FFC6D6C3"));
// Set the CardView maximum elevation
card.setMaxCardElevation(15);
// Set CardView elevation
card.setCardElevation(9);
// Initialize a new TextView to put in CardView
TextView tv = new TextView(context);
tv.setLayoutParams(params);
tv.setText("CardView\nProgrammatically");
tv.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 30);
tv.setTextColor(Color.RED);
// Put the TextView in CardView
card.addView(tv);
// Finally, add the CardView in root layout
linearLayout.addView(card);
}

ScrollView stops scrolling when child TextView changes it's span

I have a ScrollView with a TextView as it's child view, which changes it's span every second in Runnable called by MainActivity:
MainActivity:
// MainActivity's private members
private ConstraintLayout m_mainLayout;
private UnderlineSpan m_underlineSpan;
private SpannableStringBuilder m_spannableStringBuilder;
private Spannable m_spannableText;
private TextView m_textView;
private ScrollView m_scrollView;
private Runnable onUpdateTime = new Runnable()
{
#Override
public void run()
{
changeTextViewSpan();
m_mainLayout.postDelayed(onUpdateTime, 1000);
}
};
#Override
protected void onCreate(Bundle savedInstanceState)
{
m_textView = new TextView(this);
m_textView.setLayoutParams(
new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
m_scrollView.addView(m_textView );
m_spannableStringBuilder = new SpannableStringBuilder(Html.fromHtml(html)); // load long text from HTML file
m_textView.setText(m_spannableStringBuilder, TextView.BufferType.SPANNABLE);
m_spannableText = (Spannable) m_textView.getText();
}
private void changeTextViewSpan()
{
m_spannableText.setSpan(
m_underlineSpan,
startIndex,
endIndex,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}

Now, whenever I change TextView's span, the ScrollView stops scrolling, and after span is changed, ScrollView works correctly.
What I'm trying to achieve is to change the UnderlineSpan position of the long text which is loaded from the HTML file. The size of the text don't change, but it's long enough to put it into ScrollView.
Does anyone know what to do to make it scroll smoothly?
Thanks!

I am not really sure what you want to achieve.
But if you want a smooth scroll, you must set the height of your textview to a fixed size.
Then you can change textview content without changing its size every seconds.
This way the scroll must be smoothed.

Displaying ConstraintLayout in a DialogFragment

I hope you can help me out with a problem. I tried to google it, and looked through the topics here, but was unable to find an answer.
I recently changed my layouts to ConstraintLayouts, and this have been working great so far. My problem however is i had some DialogFragments displaying a LinearLayout, and when i changed it to ConstraintLayout i only shows a faded overlay, but non of the elements in the layout. If i hardcode the width and height to something like 100dp, it will display that area. When i try match_parent or any other combination the same problem applies. I also tried setting the height and width to the device height and width but still with no luck.
In the onCreateView in my CreateWeddingMetadataFragment i have:
createButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG, "Show message dialog");
FragmentManager fm = getFragmentManager();
CreateWeddingMetadataDialogFragment welcomeMessageDialog = new CreateWeddingMetadataDialogFragment();
welcomeMessageDialog.show(fm, "metadate_fragment_dialog");
welcomeMessageDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
}
});
In my CreateWeddingMetadataFragmentDialog i have:
public class CreateWeddingMetadataDialogFragment extends DialogFragment{
private static final String TAG = CreateWeddingMetadataDialogFragment.class.getSimpleName();
public Button setupNow, setupLater;
public TextView mTest;
public ConstraintLayout parentLayout;
private DialogInterface.OnDismissListener onDismissListener;
public void setOnDismissListener(DialogInterface.OnDismissListener onDismissListener) {
this.onDismissListener = onDismissListener;
}
#Override
public void onDismiss(DialogInterface dialog) {
super.onDismiss(dialog);
if (onDismissListener != null) {
onDismissListener.onDismiss(dialog);
}
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "I was called");
}
public CreateWeddingMetadataDialogFragment(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.create_welcome_message_view, container);
setupNow = (Button) view.findViewById(R.id.setupNowButton);
setupLater = (Button) view.findViewById(R.id.setupLaterButton);
mTest = (TextView) view.findViewById(R.id.welcomeMessageTitle);
parentLayout = (ConstraintLayout) view.findViewById(R.id.clWelcomeMessage);
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
int width = displayMetrics.widthPixels;
int height = displayMetrics.heightPixels;
parentLayout.setMinimumWidth(width);
parentLayout.setMinimumHeight(height);
mTest.setText("Test");
Log.d(TAG, "I was called onCreateView" + mTest);
setupNow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Go to metadate page (Hide this dialog)
}
});
setupLater.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Go to signin page and create the wedding
}
});
return view;
}
}
That is with my current try of setting it to the device size.
And here is the create_welcome_message_view:

If you need any additional information let me know, and thanks in advance.

This works fine - check out
1) Its good practice to arrange items in order where possible in XML too as visualized. Just to easily comprehend later.
2) Its looks every other element is constraining itself to others height and width and mostly resulting in 0 height and width. Watch out for 0dp and wrap_content on LayoutParams.
3) Take support of Vertical Bias too.

Also, app:layout_constraintWidth_default="wrap" (with width set to 0dp). If set, the widget will have the same size as if using wrap_content, but will be limited by constraints (i.e. it won't expand beyond them).
