Question

Long time Android user first time developer. I am trying to simply set up the fist action of my app which is two buttons one will open the browser and send the user to a URL the other will open a page that gets XML data from a url and shows the value of one node.

BUT FOR NOW I JUST WANT TO KNOW WHY I AM GETTING THE FOLLOWING ERROR:

Description Resource    Path    Location    Type
The type new View.OnClickListener(){} must implement the inherited abstract method View.OnClickListener.onClick(View)   patriosar.java  /com.patriotsar/src/com/patriotsar  line 27 Java Problem

JAVA:

package com.patriotsar;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnFocusChangeListener;
import android.widget.Button;
import android.widget.TextView;


public class patriosar extends Activity {

     private Button startButton;
     private Button subscribe;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        this.findAllViewsById();

        startButton.setOnClickListener(new OnClickListener() {            

        });

        subscribe.setOnClickListener(new OnClickListener() {            

        });

        private void findAllViewsById() {
            start = (Button) findViewById(R.id.startbutton);
            subscribe = (Button) findViewById(R.id.subscribe);
        }

    }
}

  android:layout_x="20px"
  android:textColor="#ffffff"
  />
</AbsoluteLayout>

I know it doesnt do anything but not sure why I am already getting errors. Any help would be awesome

Answer 1

You can either implement :

startButton.setOnClickListener(new View.OnclickListener(){ 
  public void onClick(){
  // do your thing
  } 
}

or you can do :

startButton.setOnclickListener(this);

 public void onClick(){
   switch(id){
     case R.id.startbutton : //do your thing
      break;
     case R.id.subscribe : //do your thing
      break;
  }

}

You need to implements OnclickListener to your activity, but if you have Eclipse, it’s automatic .
