How to know which button user clicked and its text and id in Android Studio?

Through out the whole android application I want to capture button click, radio button clicks, link click etc… basically a user interaction in whole android application. Is there any common method to detect which element user click and its values.?

    Try using onCickListener() on the buttons.

    In Kotlin:

    1. Add id to button in .xml files with android:id="@+id/nameOfButton". Every button needs an unique name.
    2. In .kt file, use setOnClickListener with the id to set up the action when user click the button.
    3. If there are several buttons, just follow step 1 and 2.

    Example:
    step 1

       <Button
    android:id="@+id/buttonSave"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Save" />

    step 2

    buttonSave.setOnclickListenter {
    //TODO: your code goes here
}

    Its very simple you just need to get the text and id of button from the onclick method. Here is java and xml code for it:
    XML:

    <Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:id="@+id/button"
  android:onclick="getid"
  android:text="Save" />

    JAVA:

    public void getid(View v){
  int id = v.getId();
  String text = v.getText();
}

    As @Muthukumar Lenin asked here is listview in xml and java

    XML:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:id="@+id/rl"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:padding="10dp"
   tools:context=".MainActivity">
   <TextView
      android:id="@+id/textview"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:textStyle="italic"
      android:textColor="#5f65ff"
      android:padding="5dp"
      android:text="Choose is the best football player?"/>
   <ListView
      android:id="@+id/listview"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_below="@id/textview" />
</RelativeLayout>

    JAVA:

    import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      ListView listView = (ListView) findViewById(R.id.listview);
      final TextView textView = (TextView) findViewById(R.id.textview);
      String[] players = new String[] {"CR7", "Messi", "Hazard", "Neymar"};
      List<String> Players_list = new ArrayList<String>(Arrays.asList(players));
      ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Players_list);
      listView.setAdapter(arrayAdapter);
      listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
         @Override
         public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String selectedItem = (String) parent.getItemAtPosition(position);
            textView.setText("The best football player is : " + selectedItem);
         }
      });
   }
}

    Some of these code are from tutorialspoint and some are edited by me.
