I have the following in my AndroidManifest.xml file:
<activity
android:name=".PickemAllPicksResultsActivity"
android:label="#string/title_activity_backActionBar"
android:parentActivityName=".PoolDetailsActivity"
android:screenOrientation="portrait" />
The above places a back button/arrow (in the action bar) in my child view in order to navigate back to the parent view.
I have the following layout for the child view:
<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"
tools:context=".PickemAllPicksResultsActivity" >
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<com.google.android.material.tabs.TabItem
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Weekly" />
<com.google.android.material.tabs.TabItem
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Overall" />
</com.google.android.material.tabs.TabLayout>
<androidx.viewpager2.widget.ViewPager2
android:id="#+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/tabLayout"
android:layout_centerHorizontal="true" />
</RelativeLayout>
When i click on the back button in the action bar the app crashes because the parent view is executing the onCreate which is calling a Firebase function:
// Get the Pool Info
poolReference = mFirebaseDatabase.getReference("PICKEMPOOLS").child(poolID);
and poolID is null.
Question, why does this back button trigger the OnCreate function, but if I press the back button on the Android Navigation is just dismisses the screen and goes to the previous view?
From my understanding, if you want to get back click the event implemented below will give you a callback when back pressed.
// This callback will only be called when MyFragment is at least Started.
OnBackPressedCallback callback = new OnBackPressedCallback(true /* enabled by default */) {
#Override
public void handleOnBackPressed() {
// Handle the back button event
}
};
requireActivity().getOnBackPressedDispatcher().addCallback(this, callback);
// The callback can be enabled or disabled here or in handleOnBackPressed()

I am making a chat app and I want to add a feature like telegram to copy links ,phone numbers and etc.. from long clicking on an auto link.I used this library to add long click listeners on a auto link.I implemented it successfully.But when I do this, i want to show a Lottie animation in the start like this but on long click of a link.
I tried many answer but I get an exception.I already made the layout for custom snakbar.It is given below
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="56dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_margin="#dimen/_3sdp"
android:backgroundTint="#color/snakbar_background"
app:cardCornerRadius="#dimen/_4sdp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical">
<com.airbnb.lottie.LottieAnimationView
android:id="#+id/lottieSnakbar"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_marginStart="#dimen/_5sdp"
android:layout_marginEnd="#dimen/_10sdp"
app:lottie_rawRes="#drawable/copy"
app:lottie_autoPlay="true"
app:lottie_loop="false"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Text copied to clipboard"
android:gravity="center_vertical"
android:theme="?snackbarTextViewStyle"
tools:ignore="HardcodedText" />
</LinearLayout>
</androidx.cardview.widget.CardView>
Now how can I achieve this?
You can use an interface in the adapter. And receive and show snakbar from activity
You could use localBroadcast and broadcast a local signal from the adapter and let the other Activity(probably receiver) handle snakbar.
AdapterClass{
LocalBroadcastManager localBroadcastManager = null;
void sendB(parms){
if(localBroadcastManager != null){
localBroadcastManager.sendBroadcast(Intent("NOTIFICATION_RECEIVER"))
}
onCreateViewHolder(){
localBroadcastManager = LocalBroadcastManager.getInstance(applicationContext)
}
onBindViewHolder(){
if(someCondition){
sendB(parms);
}
}
then receive it from an activity then call snakBar
I am building an android application where I am letting the users to sign in using google also. When they sign in using google and do not register themselves using the registration page then there are certain information which are left out.I also have a screen which updates the profile information of the user.
I want to set an icon on the home screen(kind of a bell icon) which displays that there are some notification and when the user click on that the button it tells that some information are left to be added and it redirects them to the update profile page.
The icon I want is like the notification icon(bell) in youtube.
Is there any way I can do this?

}
Note: I am not using any custom toolbar, neither am I using any toolbar, my theme for the application is: NoActionBar
There are three ways to get that notification icon depending upon the theme you are using in your Activity.
1. No.ActionBar Theme: If you're not using any ActionBar or toolbar in your activity then you can create a View(ImageView or Button) in your Activity's layout file with Height and Width as same as the notification icon which is around 28dp and then position it at the top right corner of the screen. You can change the background image of the view according to the state you want.
2. Create your own toolbar: You can create your own toolbar and set the menu item in it. While creating the menu item make sure that you select showAsAction="always" this way your icon is always visible. here is a link for the reference
3.ActionBar Theme: If you're using the action bar theme then you can create a menu file with one item like in Option 2 and then override the onCreateOptionsMenu and inflate then inflate your menu in it.
Notification notification = new Notification.Builder(this)
.setContentTitle(title)
.setContentText(text)
.setSmallIcon(R.drawable.ic_notification)
.setContentIntent(pIntent)
.setDefaults(Notification.DEFAULT_SOUND|Notification.DEFAULT_LIGHTS|Notification.DEFAULT_VIBRATE)
.setAutoCancel(true)
.build();
I've this layout:
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/input_birthdate"
style="#style/ExposedDropDownMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/birthdate">
<AutoCompleteTextView
android:id="#+id/autocomplete_birthdate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:editable="false" />
</com.google.android.material.textfield.TextInputLayout>
With this style:
<!-- ExposedDropdownMenu -->
<style name="ExposedDropDownMenu" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu">
<item name="boxStrokeColor">#color/text_input_layout_outlined_box_stroke</item>
<item name="hintTextColor">#color/green_2</item>
</style>
I've tried to set a click listener on the autocomplete text view:
autoComplete.setOnClickListener(view -> {
// This is called twice when i click the autocomplete textview
});
The listener is called twice...why? How can i solve this?
EDIT: removing the style, the first click (gaining the focus) is ignored, than the second click is called correctly once, but I lose the "ripple" background effect anyway.
You can try the setOnTouchListener instead, it's called just once and keeps the ripple as well.
autocomplete_birthdate.setOnTouchListener { view, motionEvent ->
if (motionEvent.action == ACTION_UP) {
// Some code
}
return false
}
You should try the below example.
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Click Event"
app:boxStrokeColor="#color/til_selector"
app:boxStrokeErrorColor="#color/colorRed_700"
app:boxStrokeWidth="1dp">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/etClickEvent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="1"
**android:focusableInTouchMode="false"** />
</com.google.android.material.textfield.TextInputLayout>
Now set Programmatically
etClickEvent.inputType = 0
etClickEvent.setOnClickListener{
//PUT YOUR OWN
}
This is working fine for me.
I want to show a specific text in my app toolbar but it also always shows the name of the app too. How can I get rid of the app name and only the text of the TextView?
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay"
android:fitsSystemWindows="true" >
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay"
android:fitsSystemWindows="true" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="The title I want to show"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
Add label to activity declaration in AndroidManifest.xml file.
<activity
....
android:label="Name of Your Screen"
....
</activity>
For static activity name, set android:label="Activity Name" attribute for each activity in AndroidManifest.xml
...
<activity
...
android:label="Activity Name">
...
</activity>
...
For dynamic activity name, you can use the following:
getActionBar().setTitle("Activity Name");
To provide compatibility across all the android versions, use:
getSupportActionBar().setTitle("Activity Name");
But if you want to completely get rid of the title bar, you can extend Activity instead of AppCompatActivity or you can hide the action bar:
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
you just write this line in your activity getSupportActionBar().setDisplayShowTitleEnabled(false);
and it will set the visibility of the app name to invisible
Use
<activity
android:label="blah-blah" />
to set it in the manifest file.
Or in the code toolbar.setTitle("blah-blah");
If you set your Toolbar like ActionBar then you can call actionBar.setTitle("blah-blah");.
From the modification of the accepted answer, this actually resolved my issue.
All you need to do is to leave the "label name" text as blank in your manifest as example below
...
<activity
...
android:label=" ">
...
</activity>
...
this will actually enable only your textview text in your toolbar widget to show, it works very fine for me
So I want to implement a custom Facebook share button into my Android app, but thus far I've only managed to use the native one, which I imported into my .xml file and made use of in my Java activity for that specific page.
My code looks like this (in .xml);
<com.facebook.share.widget.ShareButton
android:id="#+id/share_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="Share"
android:layout_centerHorizontal="true"/>
And in my .java, outside onCreate();
private ShareButton shareButton;
ShareLinkContent content = new ShareLinkContent.Builder()
.setContentUrl(Uri.parse("https://developers.facebook.com"))
.setContentTitle("MyTitle")
.build();
Inside onCreate();
shareButton = (ShareButton)findViewById(R.id.share_btn);
shareButton.setShareContent(content);
How would I go about making use of a custom button that I've imported into XML? Using .setShareContent obviously doesn't work if it's not an instance of ShareButton. Thanks in advance!
I have found a solution. It's clear that facebook share will work on its own button click event. So you will have to explicitly call the View.performclick() method.
Here is how i have done this:
In my layout
<com.facebook.share.widget.ShareButton
android:id="#+id/share_btn_fb"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"
android:contentDescription="#string/share" />
<LinearLayout
android:id="#+id/share_btn"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4"
android:orientation="horizontal"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:src="#drawable/google_share" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/share_google"
android:textColor="#color/green_color"
android:layout_marginLeft="5dp"
android:textSize="18sp" />
</LinearLayout>
Inside activity get refrences of these views.
ShareButton shareButton = (ShareButton) layout.findViewById(R.id.share_btn_fb);
LinearLayout shareFB = (LinearLayout) layout.findViewById(R.id.share_btn);
LinearLayout shareGoogle = (LinearLayout) layout.findViewById(R.id.share_google);
shareGoogle.setOnClickListener(this);
shareFB.setOnClickListener(this);
Inside onClick()
case R.id.share_btn :
shareButton.performClick();
break;
case R.id.share_btn_fb :
ShareLinkContent content = new ShareLinkContent.Builder()
.setContentTitle("Content title")
.setContentDescription("App descr")
.setContentUrl(Uri.parse("some url"))
.build();
shareButton.setShareContent(content);
break;
Basically shareButton.performClick(); is doing the trick.
