List with buttons

List with buttons - java

In my app i have a list with custom row,in each row i have a button and i want to set all of the buttons to the same listener. when i define a listener to the button (btn in code) my app get crash
this is how i set the list:
private void updateResultsInUi() {
lv = getListView();
lv.setTextFilterEnabled(true);
lv.setItemsCanFocus(false);
lv.setCacheColorHint(0x00000000);
ItemsAdapter adapter = new ItemsAdapter(this,R.layout.item_row, Catalog.instance());
lv.setAdapter(adapter);
lv.setTextFilterEnabled(true);
lv.setClickable(true);
Button btn = (Button)this.findViewById(R.id.cellbtn);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
int l = 0;
l++;
}
});
}
this is my row xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_height="100dp"
android:orientation="horizontal"
android:layout_width="fill_parent">
<LinearLayout android:layout_height="wrap_content"
android:weightSum="1" android:layout_marginLeft="5dp"
android:layout_width="match_parent"
android:orientation="horizontal" android:layout_weight="1">
<LinearLayout android:orientation="vertical"
android:layout_height="100dp"
android:layout_width="wrap_content">
<Button android:id="#+id/cellbtn"
android:layout_width="76px"
android:layout_height="37px" android:background="#drawable/hazmanacell"
android:layout_marginTop="20dp"/>
</LinearLayout>
<LinearLayout android:layout_height="wrap_content"
android:orientation="vertical" android:layout_width="0dp"
android:layout_weight="1" android:layout_marginRight="10dp">
<TextView android:textSize="14dp" android:layout_weight="0.50"
android:textStyle="bold" android:layout_height="wrap_content"
android:id="#+id/toptext" android:text="stam1"
android:layout_width="fill_parent"
android:gravity="right" android:textColor="#color/black" />
<TextView android:textSize="12dp" android:layout_weight="0.50"
android:layout_height="wrap_content"
android:text="stam1" android:layout_width="fill_parent"
android:id="#+id/centertext" android:gravity="right"
android:textColor="#color/black" />
</LinearLayout>
</LinearLayout>
<ImageView android:id="#+id/imageViewTwitterPic"
android:src="#drawable/icon"
android:layout_height="wrap_content"
android:layout_width="wrap_content" android:gravity="center_vertical" />
Edit
In this line :
Button btn = (Button)this.findViewById(R.id.cellbtn);
btn is null,any idea why it's happen?

in each row i have a button....In your adapter(ItemsAdapter)
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
Button btn = (Button)view.findViewById(R.id.cellbtn);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Toast.makeText(context,"clicked",Toast.LENGTH_SHORT).show();
}
});
}
in Your row.xml
<Button
android:id="#+id/cellbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:textColor="#FFFFFF" />

Why
Button btn = (Button)this.findViewById(R.id.cellbtn);
you must use Your_Item_Layout.findViewById(R.id.cellbtn);

setOnClickListener not working in fragment Android

I am trying to apply a setOnClickListener on an EditText View in a Fragment and for some reason, It is not working, the code in the listener doesn't execute when I click on the EditText.
The fragment xml:
<?xml version="1.0" encoding="utf-8"?>

The fragment code:
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.add_payment_fragment, container, false);
view.findViewById(R.id.add_pay_time).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
return view;
}

Edit text needs focus to call onClick().
Solution 1
request focus when you set listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
editText.requestFocus(); //request focus
Solution 2
set on touch listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (MotionEvent.ACTION_DOWN == event.getAction())
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
return false;
}
});
Solution 3
you can use onClickListener and onFocusChangeListener together:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showToast();//call your method
}
});
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus)
showToast();//call your method
}
});

EditText edText = view.findViewById(R.id.add_pay_time);
edText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getActivity(), "aaaa", Toast.LENGTH_LONG).show();
}
});

Use getActivity().getApplicationContext() instead

When i select RadioButton, only data in RadioButton will be obtained. And when i click button, the data will be send to another activity.
Adapter RecyclerView :
public class AdapterGetAddress extends RecyclerView.Adapter<AdapterGetAddress.ViewHolder> {
Context context;
private List<ModelGetAddress> modelGetAddressList;
private BaseApiService baseApiService;
private int previousSelected = -1;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_address, parent, false);
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, final int position) {
final ModelGetAddress adapterAddress = modelGetAddressList.get(position);
}
#Override
public int getItemCount() {
return modelGetAddressList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView nameUser, addressUser, streetName, blokAddressUser, cityAddressUser, countryUser, phoneUser;
private RadioButton radioButton;
public ViewHolder(#NonNull View itemView) {
super(itemView);
nameUser = itemView.findViewById(R.id.nameUser);
addressUser = itemView.findViewById(R.id.addressUser);
streetName = itemView.findViewById(R.id.streetName);
countryUser = itemView.findViewById(R.id.countryAddressUser);
blokAddressUser = itemView.findViewById(R.id.blokAddressUser);
cityAddressUser = itemView.findViewById(R.id.cityAddressUser);
phoneUser = itemView.findViewById(R.id.phoneUser);
radioButton = itemView.findViewById(R.id.radioButton);
radioButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
}
});
}
}
}
Code in Fragment :
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Here's were i'm stuck
}
});
return view;
}
}

You can solve this via an interface.
public interface ItemClickedCallback{
void onItemClicked(String nameUser //, the other data you wanna pass );
}
pass it through the constructor of your adapter.
Use this adapter constructor
ItemClickedCallback callback;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList, ItemClickedCallback callback) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
this.callback= callback;
}
When checking a radio button of any item; call the interface method, like this.
radioButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
callback.onItemClicked(getNameUser //, the rest..);
}
});
Now, when you initialize the adapter in the fragment, create the new interface via the constructor and assign the data to class variables like this.
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
private String nameUser_;
// the rest...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
AdapterGetAddress adapter = new AdapterGetAddress(getActivity, list, new ItemClickedCallback() {
#Override
public void onItemClicked(String userName //, the rest..) {
// assign to the class variable like this
nameUser_ = userName;
// the rest..
}
}););
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Use the data as you want..
}
});
return view;
}
}

Android Fragment transaction from list's element

return view;
}
}
onClick method works (there is "click" toast) but nothing else happens, the is nothing in AndroidMonitor if I click dataHandler.detailsIcon.
How is it possible to put fragment in framelayout in list's element?
Edit
I forgot about commit(), so now it works but only for FrameLayout from first list's element. It doesn't matter which list's element I click, fragment MealDetails is always place in the same FrameLayout.
Probably because every FrameLayout have the same id(?) is there any way to solve it?

You have forgotten to commit() your FragmentTransaction.
If you don't commit it, nothing will happen. Android Studio should be warning about this as well.

Android background color for accordion menu

I want the code in the Java file to set the background color of whatever button was clicked, and keep it, even after you let go of the button. Thanks in advance
I don't really get the formatting on here. I hope it's clear what belongs where.
Java:
package mika.actual;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class accordion extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.accordian);
Button btnProfile = (Button) findViewById(R.id.btnProfile);
Button btnSettings = (Button) findViewById(R.id.btnSettings);
Button btnPrivacy = (Button) findViewById(R.id.btnPrivacy);
View panelProfile = findViewById(R.id.panelProfile);
panelProfile.setVisibility(View.GONE);
View panelSettings = findViewById(R.id.panelSettings);
panelSettings.setVisibility(View.GONE);
View panelPrivacy = findViewById(R.id.panelPrivacy);
panelPrivacy.setVisibility(View.GONE);
btnProfile.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// DO STUFF
View panelProfile = findViewById(R.id.panelProfile);
panelProfile.setVisibility(View.VISIBLE);
View panelSettings = findViewById(R.id.panelSettings);
panelSettings.setVisibility(View.GONE);
View panelPrivacy = findViewById(R.id.panelPrivacy);
panelPrivacy.setVisibility(View.GONE);
}
});
btnSettings.setOnClickListener(new OnClickListener() {
#Override

// DO STUFF
View panelProfile = findViewById(R.id.panelProfile);
panelProfile.setVisibility(View.GONE);

If I understood correctly, what you want to do is, when clicking a button and expanding its sub-menu, change the background of that button until it is clicked again. You can do this with a Tag on the Button:
btnSettings.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// DO STUFF
//if button is not selected, change background and tag the View as selected
if(v.getTag() == null || v.getTag().equals("not_selected")) {
v.setBackgroundColor(Color.RED);
v.setTag("selected");
//show sub-menu
}
//if button is already selected, reset background and tag the View as not selected
else{
v.setBackgroundResource(android.R.drawable.btn_default);
v.setTag("not_selected");
//hide sub menu
}
}
});
Notice that v.setBackgroundResource(android.R.drawable.btn_default); is resetting the Button background to an android drawable. You may want to change this to a custom drawable or color.
You could have used an ExpandableListView to implement this kind of menu.

button.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
view.setBackgroundColor(ContextCompat.getColor(context, R.color.presed_color));
} else if (event.getAction() == MotionEvent.ACTION_UP) {
view.setBackgroundColor(ContextCompat.getColor(context, R.color.unpresed_color));
}
return false;
}
});

Fragment onCreate() issue

i need to declare my Chronometer on onCreate() of my fragment because if I declare on onCreateView(), every time the ChronometerFragment is called the Chronometer is reseted.
My actual code:
ChronometerFragment.class
public class CronometroFragment extends Fragment {
Button btStart, btPause, btReset;
boolean click;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_cronometro, container,
false);
final Cronometro cronometro = (Cronometro) v.findViewById(R.id.cronometro);
click = true;
btStart = (Button) v.findViewById(R.id.btStart);
btPause = (Button) v.findViewById(R.id.btPause);
btReset = (Button) v.findViewById(R.id.btReset);
btStart.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.start();
}
});
btPause.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.pause();
}
});
btReset.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.setBase(SystemClock.elapsedRealtime());
cronometro.stop();
}
});
return v;
}

My problem is that user cannot change fragment because this reset the Chronometer.
Please, can someone help me?
Thanks.

This question is badly formulated.. But in your onCreate, put setretaininstance(true). This should work. :-)
