Import ID switch from XML Android Studio

I have problems in Android Studio, I don't know how to import the switch ID generically, so I can call this function from all the switches.
I tried to put a description of the switch with the number of it so I can get a number like "1".
public class MainActivity extends AppCompatActivity {
Switch switch1, switch2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
switch1 = findViewById(R.id.switch1);
switch2 = findViewById(R.id.switch2);
}
public void OnClick(View view) {
String stateSwitch = "";
if(switch1.isChecked() == false){
stateSwitch = "0";
} else {
stateSwitch = "1";
}
if(switch2.isChecked() == false){
stateSwitch = "0";
} else {
stateSwitch = "1";
}
String idSwitch = switch1.getContentDescription().toString();
// What can I put instead of "switch1" or "switch2" to select the switch generically?
BackgroundWorker backgroundWorker = new BackgroundWorker(this);
backgroundWorker.execute("switch", stateSwitch, idSwitch);
}
}
XML of the switches
<Switch
android:id="#+id/switch2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="2"
android:onClick="OnClick"
android:text="switch2" />
<Switch
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="1"
android:onClick="OnClick"
android:text="switch1" />
Sorry for my english.

To get an ID of widget in a code simply get view.getId() it will return a positive integer used to identify the view,
to get id generically you can call
String mId = Integer.toString(view.getId());
when you click on switch1 it will return the id of switch1 similarly when you click on switch2 it will return the id of switch2.

Use checked changed listener and get the id there. For example:
<Switch
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="152dp"
android:text="Switch1"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Switch
android:id="#+id/switch2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:text="Switch2"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/switch1" />
//////////Java Code///////////
public class MainActivity extends AppCompatActivity {
Switch gSwitch,switch1, switch2;
boolean state;
int id;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
switch1 = findViewById(R.id.switch1);
switch1 = findViewById(R.id.switch2);
switch1.setOnCheckedChangeListener(checkedChangeListener);
switch2.setOnCheckedChangeListener(checkedChangeListener);
}
CompoundButton.OnCheckedChangeListener checkedChangeListener = new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
id = buttonView.getId();
gSwitch = findViewById(id);// generic switch;
state = isChecked;
// call your method here for example:
// BackgroundWorker backgroundWorker = new BackgroundWorker(this);
// backgroundWorker.execute("switch", state, id);
}
};
}

Use View Binding
For each module that uses view binding, set the viewBinding build option to true in the module-level build.gradle file:
buildFeatures {
dataBinding = true
}
And Remove all imports from kotlinx.android.synthetic.

If another files is needed in order to help me, let me know and i'll upload it.
Thanks you so much guys.

create a class like
public class TestAdapter extends BaseAdapter {
Context context;
public TestAdapter(Context context)
{
this.context=context;
}
//count of number of items in listview may be depending on the array ua passing....here i am keeping 5 it may be according to you!
int count=5;
#Override
public int getCount() {
return 5;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView= LayoutInflater.from(context).inflate(R.layout.row_item,parent,false);
TextView ordentitle=(TextView)convertView.findViewById(R.id.orden_title_text);
TextView textbox1=(TextView)convertView.findViewById(R.id.textbox1);
ordentitle.setText("Whatever yout text is");
textbox1.setText("whatever your text is");
Button editar=(Button)convertView.findViewById(R.id.edit_btn);
Button cancel=(Button)convertView.findViewById(R.id.cancel_btn);
editar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//funtionality of edit button
}
});
cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//functionality of cancel button
}
});
return convertView;
}
}
and then set this adapter to your listview in activity or fragment like this:
TestAdapter testAdapter=new TestAdapter(YourActivity.this)
yourlistview.setAdapter(testAdapter);
one more pointer :
YOU GAVE EDIT BUTTON id as cancel_btn and CANCEL BUTTON id as edit_btn!

You could create a new class that extends BaseAdapter and in the getView method you do w/e you want with the buttons. In the the activity with the listView you use the setAdapter.

Country code is not getting from country code picker in Android

I am developing an signup activity in android app. I want show the country telephone code(get the country from device). It may show the list of countries containing with flag, country telephone code, country name. I get the code of country code picker from https://github.com/mukeshsolanki/country-picker-android . It contain the complete code. I want to set the default country is in the phone.
TelephonyManager tm = (TelephonyManager)this.getSystemService(this.TELEPHONY_SERVICE);
String countryCodeValue = tm.getNetworkCountryIso();
System.out.println("country = "+country);
When i using this code i get the country code "in". But i want to display telephone code and flag, name. When i open the screen. I want to display it automatically.
My code is shown below

You can use this library
Click here
by then you can do this
new DialogPlusBuilder().blurBackground()
.buildCountriesListDialog(true,new DialogPlus.CountriesDialogListener() {
#Override
public void onItemClicked(CountryDataModel countryDataModel, DialogPlus dialogPlus) {
super.onItemClicked(countryDataModel, dialogPlus);
Toast.makeText(MainActivity.this,countryDataModel.getName()+ countryDataModel.getPhone_code(), Toast.LENGTH_SHORT).show();
}
})
.show(this.getSupportFragmentManager(), "Countries List Dialog");

ListActivity not loading adapters style, loading white screen

Here is how I am api through retrofit:
public interface MovieAPI {
#GET("/3/movie/273248?api_key=ea8f68dc2c7b43a3df248b9a638f5fb4")
void getMovieDetails(Callback<List<MovieDetail>> callback);
#GET("3/movie/5493/movie/549")
void getPopularMovies(Callback<List<MovieDetail>> response);
}
Here is the model for the objects I am trying to read in from the callback:
public class MovieDetail {
private String poster_path;
private String release_date;
private int id;
private String original_title;
private double vote_average;
private int gridPos;
private Bitmap bitmap;
public int getGridPos() {
return gridPos;
}
public void setGridPos(int gridPos) {
this.gridPos = gridPos;
}
public String getPoster_path() {
return poster_path;
}
public void setPoster_path(String poster_path) {
this.poster_path = poster_path;
}
public String getRelease_date() {
return release_date;
}
public void setRelease_date(String release_date) {
this.release_date = release_date;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getOriginal_title() {
return original_title;
}
public void setOriginal_title(String original_title) {
this.original_title = original_title;
}
public double getVote_average() {
return vote_average;
}
public void setVote_average(double vote_average) {
this.vote_average = vote_average;
}
public Bitmap getBitmap() {
return bitmap;
}
public void setBitmap(Bitmap bitmap) {
this.bitmap = bitmap;
}

Custom adapter for listview using pasrequery

I am trying to create a demo app where the users enter a search and destination, the data will be queried from parse.com and then the matching result will be displayed in the next screen's listview. I have followed a few tutorials but for sure haven't been able to grasp the concept concretely enough. When I enter a search query, the progress bar shows up and then the application goes back into the previous activity. I can't understand where exactly things are going wrong.
This is my mainactivity class.
public class CarpoolingActivitySearch extends ActionBarActivity {
ListView listView;
ArrayList<Travellers> travellers;
CarpoolingAdapter adapter;
protected ProgressDialog proDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_carpooling_activity_search);
final EditText mSrc = (EditText)findViewById(R.id.carpooling_source);
final EditText mDst = (EditText)findViewById(R.id.destination);
Button mSubmitButton = (Button)findViewById(R.id.carpooling_submit);
mSubmitButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String source = mSrc.getEditableText().toString();
String destination = mDst.getEditableText().toString();
listView = (ListView) findViewById(R.id.list);
ParseQuery<ParseObject> query = ParseQuery.getQuery("Carpooling");
query.whereEqualTo("Source", source); //assume you have a DonAcc column in your Country table
query.whereEqualTo("Destination", destination); //assume you have a DonAcc column in your Country table
startLoading();
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> parseObjects, ParseException e) {
if(e==null)
{
for(int i=0;i<parseObjects.size();i++)
{
Travellers travellers1 = new Travellers();
travellers1.setSource("Source");
travellers1.setDestination("Destination");
travellers.add(travellers1);
if(travellers.size() > 0)
{
adapter = new CarpoolingAdapter(getApplicationContext(),R.layout.activity_carpooling_activity_search,travellers);
listView.setAdapter(adapter);
} else {
AlertDialog.Builder popup = new AlertDialog.Builder(CarpoolingActivitySearch.this);
popup.setMessage("Seems our servers are busy. Try again in some time.");
popup.setPositiveButton("Back",null);
AlertDialog dialog = popup.create();
dialog.show();
}
}
stopLoading();
finish();
}
else {
stopLoading();
AlertDialog.Builder popup = new AlertDialog.Builder(CarpoolingActivitySearch.this);
popup.setMessage(e.getMessage());
popup.setPositiveButton("Back",null);
AlertDialog dialog = popup.create();
dialog.show();
}
}
});
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_carpooling_activity_search, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
protected void startLoading() {
proDialog = new ProgressDialog(this);
proDialog.setMessage("loading...");
proDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
proDialog.setCancelable(false);
proDialog.show();
}
protected void stopLoading() {
proDialog.dismiss();
proDialog = null;
}
}
I have created a custom adapter for this purpose.
public class CarpoolingAdapter extends ArrayAdapter<Travellers> {
ArrayList<Travellers> travellersArrayList;
LayoutInflater vi;
int Resource;
ViewHolder holder;
Context context;
public CarpoolingAdapter(Context context, int resource, ArrayList<Travellers> objects) {
super(context, resource, objects);
vi = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Resource = resource;
travellersArrayList = objects;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView== null) {
convertView = vi.inflate(Resource,null);
holder = new ViewHolder();
holder.mSource = (TextView)convertView.findViewById(R.id.textView);
holder.mDestination = (TextView)convertView.findViewById(R.id.textView2);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
holder.mSource.setText(travellersArrayList.get(position).getSource());
holder.mDestination.setText(travellersArrayList.get(position).getDestination());
return convertView;
}
static class ViewHolder {
public TextView mSource;
public TextView mDestination;
}
}
And the travellers class with a default constructor and getter/setter methods.
public class Travellers {
private String Source;
private String Destination;
public Travellers() {
}
public Travellers(String source, String destination) {
super();
Source = source;
Destination = destination;
}
public String getSource() {
return Source;
}
public void setSource(String source) {
Source = source;
}
public String getDestination() {
return Destination;
}
public void setDestination(String destination) {
Destination = destination;
}
}
The main layout file named activity_carpooling_activity_search.xml.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="com.example.android.myapplication.Carpooling.Carpooling">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/carpooling_source"
android:hint="Source"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"

<EditText

<Button

<ScrollView

<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/list" />
</ScrollView>
</RelativeLayout>
And finally my list_item_deatil.xml file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"

<TextView

</LinearLayout>
What should I modify to make it work appropriately? I am not getting any errors as such.

First of all, you have posted a very long code blocks where indentation is not good enough to read you code.
So what I understood, as your ParseException e is null that means there is no exception. Inside that if block, after the for loop you are calling finish() which is causing your current activity instance to be destroyed thus going to previous activity.
I hope this helps you.
