public class ProgressService {
public Integer getCurrentProgerss(double current, double max) {
Integer i=(int)((current / max) * 100) ;
return i;
}
} 具体步骤如下:
import android.test.InstrumentationTestCase;
public class TestClass extends InstrumentationTestCase {
public void test() throws Exception{
ProgressService progressService=new ProgressService();
Integer pro=progressService.getCurrentProgerss(20, 70);
Log.i(TAG, pro.toString());
}
}选中刚刚新建的测试类TestClass,右键->run->TestClass,如图:
