我如何称职?
public static void dial(Activity call)
{
Intent intent = new Intent(Intent.ACTION_DIAL);
call.startActivity(intent);
}
Obviously not with:
dial(); /*Something should be within the brackets*/

你可以放弃。 你们必须发出一个背景目标。
职能在哪里? 如果在某项活动或活动范围内进行,则只是将“这”作为参数。
If it s inside an BroadcastListener, or a Service, just change the parameter to Context and pass "this".
You should try
ClassName.dial();
原因是静态方法属于阶级本身,而不是属于个别情况。 电话instance.dial(
)是合法的,但受到劝阻。
you should use your ClassName.StaticMethod.... to call a static method of a class
问题有什么例外?
If you ve got a class like
public class Test {
public void nonStaticFct() {
staticFct();
}
public static void staticFct() {
//do something
}
}
完全可行(即使你总是按职等称职)。 FctName( 试验.staticFct(
)
我在此猜测这个问题是缺失的论点。
根据http://www.oracle.com/technetwork/java/codeconventions-137265.html#587“rel=“nofollow”),我错了。 Java Code Conventions 您可以简单地使用一种分类方法,而不使用类别名称(即使似乎有错),因为我预计会暗中这样做。
