Using getContentResolver in BroadcastReceiver extended class

问题

I have to use the getContentResolver method in a class that extends BroadcastReceiver and I found that getContentResolver can be used only in a class that extends Activity. I try to do a static method in a class that extends activity but i can't use getContentResolver in a static method. I also tried with a non-static method but when i run the appliaction I get an error. How can I do? Thanks!

回答1:

In your onReceive(Context, Intent) you receive a Context object which has a getContentResolver() Method.

回答2:

ContentResolver contentResolver =context.getContentResolver();
cursor = contentResolver.query(uri, projection, selection, selectionArgs, sortOrder);
