Question

I am trying to make an alarm application, and found this code online. But when I copied it into eclipse, it gives an error on the startAlert method and says “void is an invalid type for the variable startAlert”.

package tanvi.alarm;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        public void startAlert(View view) {
            EditText text = (EditText) findViewById(R.id.editText1);
            int i = Integer.parseInt(text.getText().toString());
            Intent intent = new Intent(this, MyBroadcastReceiver.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
                    + (i * 1000), pendingIntent);
            Toast.makeText(this, "Alarm set in " + i + " seconds",
                    Toast.LENGTH_LONG).show();

    }
}

You should put the function under the onCreate() method, then call it inside the onCreate() method.
