在静态SQLiteDatabase类中调用非静态方法

Question

i want to display a msg to the user (msg box or Toast) when exception happend in a static SQLite Database class that i use.

the problem is that i cant call a non static method in a static class , how can i handle this.

this is the class

private static SQLiteDatabase getDatabase(Context aContext) {

and i want to add something like this in the class when exception happen but context generates the problem of reference to non static in static class.

Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;

Toast toast = Toast.makeText(context, text, duration);
toast.show();

Answer 1

It sounds like you're trying to use the "getApplicationContext()" function, which is a nonstatic method. You can't call nonstatic methods from static ones. Why don't you just use the context that is passed in? ie,

Context context = aContext;
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;

Toast toast = Toast.makeText(context, text, duration);
toast.show();
