How to make back button in webview?

Question

Java

When I press the back button, the application closes, how can I make it go back to the previous page?

package test.test;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;


public class MainActivity extends Activity {

    WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webView = (WebView) findViewById(R.id.webview);

        webView.getSettings().setJavaScriptEnabled(true);

        webView.loadUrl("http://");
        webView.setWebViewClient(new WebViewClient() {
                                     @Override
                                     public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                                         return super.shouldOverrideUrlLoading(view, request);
                                     }
                                 }

        );
    }
}
