make a method available to all Activities-CodePudding

I have a method "InitView", I want to call it in every Activity, I create a class "Helper" and in it my method I make it static and pass Activity like parameter.

I'm wondering if its the best solution and if there is no memory leak or something like that. here is my code:

public class Helper {

    public static void intView(Activity activity) {
        Window window = activity.getWindow();
        Drawable background = ResourcesCompat.getDrawable(activity.getResources(), R.drawable.gradient_bg, null);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(activity.getResources().getColor(android.R.color.transparent));
        //window.setNavigationBarColor(this.getResources().getColor(android.R.color.transparent));
        window.setBackgroundDrawable(background);
    }
}

You can do this by Inheretance.

You can do a base Activity, that contains the initView function line of code.

public class BaseActivity extends Activity {
     @Override
     protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     initView();
     }

     private void initView(){
 
      Window window = activity.getWindow();
      Drawable background = ResourcesCompat.getDrawable(activity.getResources(), R.drawable.gradient_bg, null);
      window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
      window.setStatusBarColor(activity.getResources().getColor(android.R.color.transparent));
      //window.setNavigationBarColor(this.getResources().getColor(android.R.color.transparent));
      window.setBackgroundDrawable(background);

     }
}

You can extend this BaseActivity to your activities

public class YourActivity extends BaseActivity {

}

Now, you are 100% sure that no leak, and you get rid of static keyword.
