常量
Java中：
class StaticDemoActivity {
public static final String LOAN_TYPE = "loanType";
public static final String LOAN_TITLE = "loanTitle";
}
Kotlin中：
class StaticDemoActivity {
companion object {
val LOAN_TYPE = "loanType"
val LOAN_TITLE = "loanTitle"
}
}
或者
class StaticDemoActivity {
companion object StaticParams{
val LOAN_TYPE = "loanType"
val LOAN_TITLE = "loanTitle"
}
}
或者
class StaticDemoActivity {
companion object {
const val LOAN_TYPE = "loanType"
const val LOAN_TITLE = "loanTitle"
}
}

TestEntity类引用StaticDemoActivity中的常量
class TestEntity {
public TestEntity () {
String title = StaticDemoActivity.Companion.getLOAN_TITLE();
}
}
或者
class TestEntity {
public TestEntity () {
String title = StaticDemoActivity.StaticParams.getLOAN_TITLE();
}
}
或者
class TestEntity {
public TestEntity () {
String title = StaticDemoActivity.LOAN_TITLE;
String type= StaticDemoActivity.LOAN_TYPE;
}
}
静态方法
Java代码：
class StaticDemoActivity {
public static void test(){
、、、
}
}
Kotlin中：
class StaticDemoActivity {
companion object {
fun test(){
、、、
}
}
}
或者
class StaticDemoActivity {
companion object StaticParams{
fun test() {
、、、
}
}
}
引用静态方法（这里的引用只针对于java引用kotlin代码）
TestEntity类引用StaticDemoActivity中的静态方法
class TestEntity {
public TestEntity () {
StaticDemoActivity.Companion.test();
}
}
或者
class TestEntity {
public TestEntity () {
StaticDemoActivity.StaticParams.test();
}
}
