Question

I am a noob to android and I have a Map Activity that also uses OverlayItems. Within the onButtonTap method of my overlay class, I want to execute startActivity so i can then use intent.ACTION_CALL.

Intent callIntent = new Intent(Intent.ACTION_CALL);   
callIntent.setData(Uri.parse("tel:"+MapActivity.phonenumber0));
startActivity(callIntent);

in the code above i am asked to create a method for startActivity(Intent), which I don’t understand. and when i try…

Intent callIntent = new Intent(Intent.ACTION_CALL);   
callIntent.setData(Uri.parse("tel:"+MapActivity.phonenumber0));
MapActivity.startActivity(callIntent);

It says i cannot make a static reference to a non static reference to a non-static method. And when I try to use the context of the object, which is the button being tapped it won’t allow me to do so.

Intent callIntent = new Intent(Intent.ACTION_CALL);   
callIntent.setData(Uri.parse("tel:"+MapActivity.phonenumber0));
ContextObj.startActivity(callIntent);

And of course moving this block of code to the main Activity requires a static method which presents its own set of issues.

How can set the appropriate context for startActivity? Any help is greatly appreciated.

Answer 1

you can create method in your MapActivity class like this to get context…

Edit :
Take some static variable like this…

public static Context mContext;

In Activity’s onCreate() method assign base context to it…

mContext = getBaseContext();

& return mContext…

public static Context getContext() {
    return mContext;
}

& call it in to your non activity class to start activity…

Intent callIntent = new Intent(Intent.ACTION_CALL);   
callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
callIntent.setData(Uri.parse("tel:"+MapActivity.phonenumber0));
MapActivity.getContext().startActivity(callIntent);
