 In this case as ragavendran suggested, call an Intent to start up the
 new activity. Something like

        Intent eSkyGuideIntent = new Intent() ;
        eSkyGuideIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        eSkyGuideIntent.setClassName
 (yourPackageName.eSkyGuide,yourPackageName.eSkyGuide);

        mContext.startActivity(eSkyGuideIntent);

 Make sure that you have a valid context instance. With doing this your
 new activity should be started.

A more general Java beginners group seems more appropriate for this question.

[android-developers] Re: How to call another class method.

2009-08-28 Thread Lutz Schönemann 

you need a reference to the class that contains the method you want to  
call.

To access the mehtod homepage() inside the eSkyGuide from the class  
Weather, you need an instance of the eSkyGuide class inside the  
instance of the Weather class.

for example:

public class Weather extends Activity implements  
Button.OnClickListener {
private eSkyGuide meSkyGuide = new eSkyGuide();

private someMethod() {
meSkyGuide.homepage();
}

}

But you shouldn't do this, because you are trying to set the content  
view of an activity from inside an other activity. Things like  
setContentView(), setOnClickListener(), ... should be done once at  
creation time of an activity:

public class eSkyGuide extends Activity implements  
Button.OnCickListener {
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.homepage);
flight_schedule=(Button)findViewById(R.id.fschedule);
flight_schedule.setOnClickListener(this);

flight_status=(Button)findViewById(R.id.fstatus);
flight_status.setOnClickListener(this);

weather=(Button)findViewById(R.id.weather);
weather.setOnClickListener(this);
}
}


In addition: instead of implementing the OnClickListener interface you  
can implement an OnClickListener like this:

flight_schedule.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// put your code here
// to call methods of the eSkyGuide class do it like 
this
eSkyGuide.this.methodName();
}
});

[android-developers] Re: How to call another class method.

2009-08-28 Thread Roman ( T-Mobile USA) 

I am assuming that you want to get the activity eSkyGuide in the
foreground, correct?

In this case as ragavendran suggested, call an Intent to start up the
new activity. Something like

   Intent eSkyGuideIntent = new Intent() ;
   eSkyGuideIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

   eSkyGuideIntent.setClassName
(yourPackageName.eSkyGuide,yourPackageName.eSkyGuide);

   mContext.startActivity(eSkyGuideIntent);

Make sure that you have a valid context instance. With doing this your
new activity should be started.
