Problem at Android Studio 3.1.3 !!!!!!

[mostafaamirhaghi1370]

ello
I installed Android Studio 3.1.3
I installed all Sdk
But he does not know a whole series of public classes like findviewbyid
The next problem is that I've added a series of library to the project but gets the error
I'm taking two pictures. I'm having trouble !!!!

Truly this is my SDK project information

compileSdkVersion 28
buildToolsVersion '27.0.3'
useLibrary 'org.apache.http.legacy'
defaultConfig {
    minSdkVersion 22
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

Thank you for guiding me what to do

Give complete information. Is it just one java file or are others having this problem? Your screenshot shows there are many others. Only then can we try to diagnose the issue.
