MainActivity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.bilalkhawaja.pmeialumni.MainActivity">

<im.delight.android.webview.AdvancedWebView
    android:id="@+id/webView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
</RelativeLayout>

这是ManinActivity.JAVA代码

import im.delight.android.webview.AdvancedWebView;

public class MainActivity extends AppCompatActivity implements 
AdvancedWebView.Listener {

    String Url = 
"https://curj.000webhostapp.com/pmei_alumni/pmei_alumni.php";

    public AdvancedWebView mWebView;


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

mWebView = (AdvancedWebView) this.findViewById(R.id.webView);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl(Url);
mWebView.setListener(this,this);
}

@SuppressLint("NewApi")
@Override
protected void onResume() {
super.onResume();
mWebView.onResume();
// ...
}

@SuppressLint("NewApi")
@Override
protected void onPause() {
mWebView.onPause();
// ...
super.onPause();
}

@Override
protected void onDestroy() {
mWebView.onDestroy();
// ...
super.onDestroy();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent 
intent) {
super.onActivityResult(requestCode, resultCode, intent);
mWebView.onActivityResult(requestCode, resultCode, intent);
        // ...
}

@Override
public void onBackPressed() {
if (!mWebView.onBackPressed()) { return; }
// ...
        super.onBackPressed();
    }



@Override
public void onPageStarted(String url, Bitmap favicon) {

    }

    @Override
    public void onPageFinished(String url) {

    }

@Override
public void onPageError(int errorCode, String description, String 
failingUrl) {

    }

 @Override
 public void onDownloadRequested(String url, String suggestedFilename, 
String mimeType, long contentLength, String contentDisposition, String 
userAgent) {

    }

    @Override
    public void onExternalPageRequest(String url) {

    }
    }
