Question

Trying to make a spinner in android:

package com.example.test; 
import android.app.Activity;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.BaseAdapter;

public class SpinnerBuilding extends Activity {
Spinner spinner = (Spinner) findViewById(R.id.building);

// Create an ArrayAdapter using the string array and a default spinner layout
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
        R.array.buildings_array, android.R.layout.simple_spinner_item);

// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

// Apply the adapter to the spinner
spinner.setAdapter(adapter);
}

It throws an error saying "Syntax error on token "setDropDownViewResource", identifier expected after this token. Moreover, the spinner.setAdapter(adapter); also does not work.

Could somebody help me with this??

Answer 1

You need to move the whole code inside some method, You cannot execute code from outside of method in a class.

Preferably move the whole code inside Oncreate.

public class SpinnerBuilding extends Activity {
public void onCreate(Bundle b){

super.onCreate(b);
setContentView(R.id.layout);
Spinner spinner = (Spinner) findViewById(R.id.building);

// Create an ArrayAdapter using the string array and a default spinner layout
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
        R.array.buildings_array, android.R.layout.simple_spinner_item);

// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

// Apply the adapter to the spinner
spinner.setAdapter(adapter);
}
}
