spinner has no "getSelectedItem". https://developer.android.com/reference/android/widget/Spinner.html https://developer.android.com/guide/topics/ui/controls/spinner.html and here's how you get the text-value of the selected row: https://stackoverflow.com/a/15545909/3022387

spin.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                String imc_met=spin.getSelectedItem().toString();

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

Answer 3

Implement spinner.setOnItemClickListener and then find text inside that method like this.

spinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
              String result = sp.getSelectedItem().toString();
              txt.setText(result);
            }
        });

You can't get selected Item before setting adapter.Try this below code

public class MainActivity extends AppCompatActivity {

final TextView txt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

txt=(TextView) findViewById(R.id.txt1) ;

ArrayList<ItemData> list=new ArrayList<>();
list.add(new ItemData("Cash",R.drawable.paymentcashnew));
list.add(new ItemData("Paytm",R.drawable.paymentpaytmnew));

Spinner sp=(Spinner)findViewById(R.id.select_cash);
SpinnerAdapter adapter=new SpinnerAdapter(this,
        R.layout.spinner,R.id.txt,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp.setAdapter(adapter);
sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()     {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    Object item = parent.getItemAtPosition(position);
String result = sp.getSelectedItem().toString();
txt.setText(result);

}
public void onNothingSelected(AdapterView<?> parent) {
}
});


}
}
