Need help with Android app mpg calculator

Postby jemills27 » Thu Apr 28, 2011 5:59 pm

Trying to finish up my code for my app for my class, making a small mpg calculator, it keeps giving me error on my setOnClickListener. Does anyone have any suggestions on my code or know why its saying syntax error?

Error eclipse gives me
Multiple markers at this line
- Syntax error on token "setOnClickListener", = expected after
this token
- Syntax error on token(s), misplaced construct(s)


public class mpgCalculator extends Activity {



final Button mpgbutton = (Button) findViewById(R.id.button1);
final EditText miles = (EditText) findViewById(R.id.editText1);
final EditText gallons = (EditText) findViewById(R.id.editText2);
final TextView display = (TextView) findViewById(R.id.textView1);
double miles_double;
double gallons_double;
double finalCal;


mpgbutton.setOnClickListener(new OnClickListener() {
//error here ^^
public void onClick(View v){

miles_double = Double.parseDouble(miles.getText().toString());
gallons_double = Double.parseDouble(gallons.getText().toString());
finalCal = miles_double / gallons_double;
display.setText(String.valueOf(finalCal));

}
});


}// end class


Thanks

There is no issue in your code , may be you didn't import right action listener , make sure you import android.view.View.OnClickListener , and try to implement onClickListener in your class , tell me if it works or not
