We Keep Coding

I want to make a search bar for this code to search by buttons (between btn1 and btn2 and btn3) and hide the non-matched results

I am trying to add a search bar that enables me to search by buttons, search between btn1 and btn2 and btn3. I tried a lot of codes but all of them were focused on TextView and not on buttons. So hope to help me and if I missed details please let me know to describe more.
The two files (.java and .xml) are typed below. thank you.

What do you mean by search by buttons? Are you looking to search the text that is held within the button?
Here is a way you can go about this:
Make a list that contains all the instances of your buttons.
List(findViewById(R.id.btn1), etc)
List<Button> buttonList = new ArrayList<>();
buttonList.add(view.findViewById(R.id.button_search1));
buttonList.add(view.findViewById(R.id.button_search2));
buttonList.add(view.findViewById(R.id.button_search3));
We are going to use the listeners available to the search view to do the work.
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
// You can use this for when the submit is clicked
#Override
public boolean onQueryTextSubmit(String s) {
// We loop over the button list
for(int i = 0; i < buttonList.size(); i++) {
// We get the text of the button
String buttonText = (String) buttonList.get(i).getText();
// We turn both the button text and search result to lowercase
// So that results are not case sensitive
// If they match
if(buttonText.toLowerCase(Locale.ROOT).equals(s.toLowerCase())) {
// We make button visible
buttonList.get(i).setVisibility(View.VISIBLE);
} else {
// If it doesn't, we make invisible
buttonList.get(i).setVisibility(View.INVISIBLE);
}
}
return false;
}
// You can use this when the text is changing.
#Override
public boolean onQueryTextChange(String s) {
// If text is empty, reset results
if(s.isEmpty()) {
for(int i = 0; i < buttonList.size(); i++) {
buttonList.get(i).setVisibility(View.VISIBLE);
}
}
return false;
}
});

Android Fragments - Edit Text Of Another Fragment

So I have made a simple heating text control app and it all works with permissions and all of that but it uses 2 fragments and inside them are two textboxes which I want to have the same text in -- phone number. I cannot get the edittext in rel2 to be changed by rel1.

EDIT:
I would like the edit text in Rel2 to change when I press save in rel1 therefore the phone number boxes will always be the same.
rel1
EDIT 2:
I have fixed the shared prefs issue but I would still like to know if anyone can make the textboxes the same wherether that is on text update or on save button press.

There are two ways you can do this.
Using Interface
Create an interface with a method something like TextChangeListener and declare a method onTextChange(String text).
interface TextChangeListener{
void onTextChange(String number);
}
Implement the interface in the HostActivity
class HostActivity extends Activity implements TextChangeListener{
...
void onTextChange(String number){
secondFragment.updateNumber(number)
}
...
}
In FirstFragment call the activity using the implmented interface in the afterTextChanged() listener of TextWatcher
class FirstFragment extends Fragment{
private TextChangeListener activity;
#Override
public onAttach(Context context){
if(context instanceof TextChangeListener){
activity = (TextChangeListener) context;
}
}
phNumEditText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
activity.onTextChange(s.toString);
}
...
);
...
}
In SecondFragment on receiving the call from activity, update the EditText with new data.
class SecondFragment extends Fragment{
...
public void updateNumber(String number){
editText.setText(number);
}
}
Using EventBus
Use EventBus to post an event from FirstFragment. The event will contain the data to be populated in SecondFragment. The SecondFragment will Subscribe to the event and on receiving the event the data will be populate into the EditText.

Fragment Not Appearing

I'm working on an app where I made a "custom keyboard" of sorts where you can "type in" playing cards. I made that "keyboard" a fragment and I am trying to make it appear on my main activity but it won't show up. I've looked everywhere but can't find a solution. As you can probably tell, I'm pretty new to android and especially fragments. Any help would be appreciated.

Thanks again in advance!

You have to create an instance of your fragment - not only a generic fragment.
Like:
CardKeyboardFrag cardFrag = new CardKeyboardFrag();
and
transaction.add(R.id.fragment_container, cardFrag);

code for image run in arraylist

i do array list with images thet i want them to run with 2 buttons thet go next pic and beck pic i dont know the code for this i thx all for the time you spend for help.

Inflated layout's buttons onClick listener not working

The problem is that the view you are adding does not have a parent and therefore is not able to receive click events. Currently you're inflating the view using
View playv = inflater.inflate(R.layout.level, null);
You'll want to place a parent view in that second argument.
View playv = inflater.inflate(R.layout.level, parentView, false);
This will allow you to use a parent view but not actually attach it.

So the buttons are in your level and play layouts, and you're inflating those layouts, but it doesn't look like you're ever adding the layouts to the your main view/layout. Are you actually able to see those two layouts you are inflating?

inflation is async method, can you try to add the click listener after its inflated
//only inflate in oncreate / onresume
inflater.inflate(
R.layout.play, // resource
this, // root
true); //attach to root
//overide onFinishInflate and get the view here
protected void onFinishInflate() {
super.onFinishInflate();
Button gotomenu = (Button) levelv.findViewById(R.id.tomenu);
gotomenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
toMenuOnClick(v);
}
});
}

There is no apparent reason why this should not work.
Any runtime created views must be added to your linearlayout(or any other parent layout)
using :
linearLayoutMain.addView(updateLevel);
Have you used this buttons in any of the linear layouts in your xml file i.e. does these buttons appear when you reach the corresponding activity?

You should be seeing the exception at tbl.addView(updateLevel);, because you are trying to add a view whose parent is already specified.
Are you not seeing this exception ?

If You want item value on item click just use .setTag(some value); and getTag();
RelativeLayout firstContactRlayout = (RelativeLayout) myLayout.findViewById(R.id.firstContactRlayout);
firstContactRlayout.setTag(number);
firstContactRlayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String gettags = (String) v.getTag();
Log.e("gettags", "--" + gettags);
}
});

Try this after tbl.addView(updateLevel); 0 of tbl.getChildAt(0) may change:
tbl.getChildAt(0).findViewById(R.id.updateLevel).setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
updateLevelOnClick(v);
}
});
