I try to change page on android application. It have error but look like its swap a little while.
public class gps_gui extends Activity implements View.OnClickListener{
/** Called when the activity is first created. */
private static final int ACTIVITY_CREATE = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button login = (Button) findViewById(R.id.login);
login.setOnClickListener((OnClickListener) this);
}
public void onClick(View v){
//Toast.makeText(this, "Already Login",Toast.LENGTH_SHORT).show();
Intent i = new Intent(this, SecondPage.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
}
public class SecondPage extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.second_page);
}
}
In AndriodManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="gps.GUI"
android:versionCode="1"
android:versionName="1.0">
