Hello everybody,
i've searched for days but cant find an answer, perhaps you guys can help.
I'm creating an android app in eclipse, it all works just one thing is bugging me.
this is my main.java:
package com.test;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
public class Main extends Activity implements OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Add Click listeners for all buttons
View firstButton = findViewById(R.id.btn_rassen);
firstButton.setOnClickListener(this);
View secondButton = findViewById(R.id.button2);
secondButton.setOnClickListener(this);
}
// Process the button click events
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.btn_rassen:
Intent j = new Intent(this, Webscreen.class);
j.putExtra(com.test.Webscreen.URL,
"http://www.google.com/");
startActivity(j);
break;
case R.id.button2:
Intent k = new Intent(this, Webscreen.class);
k.putExtra(com.test.Webscreen.URL,
"http://notworkingurltotest.com");
startActivity(k);
break;
}
}
}
now when it calls the webview.java the page called shows up but not the buttons i created in the layout xml page. does anybody have any idea why this is?
