我正在https://turnbackhoax.id/
内设置网址WebView
。但是WebView
仅显示空白页。我试图设置其他URL,这些工作。我已经学习并搜索了类似的问题,但没有任何改变。
以下是我的WebView
代码:
public class LaporPage extends AppCompatActivity {
private WebView webV;
Activity activity;
private ProgressDialog progDailog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lapor_page);
activity = this;
progDailog = ProgressDialog.show(activity, "Loading","Please wait...", true);
progDailog.setCancelable(false);
webV = (WebView) findViewById(R.id.web_view);
webV.getSettings().setDomStorageEnabled(true);
webV.getSettings().setJavaScriptEnabled(true);
webV.getSettings().setLoadWithOverviewMode(true);
webV.getSettings().setUseWideViewPort(true);
webV.setWebChromeClient(new WebChromeClient());
webV.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progDailog.show();
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, final String url) {
progDailog.dismiss();
}
});
webV.loadUrl("https://turnbackhoax.id/");
}
}

我检查了URL,它在Web视图中引发SSL握手错误。尽管忽略SSL错误不是一个好习惯,但这可以解决您的问题
webview.setWebViewClient(new WebViewClient(){
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler,SslError error) {
handler.proceed();
}
});

在您的Manifest.xml中添加此权限
<uses-permission android:name="android.permission.INTERNET" />
使用此:
wv = (WebView) findViewById(R.id.web_view);
wv.setInitialScale(1); //webview page matches the screen size.
wv.getSettings().setLoadWithOverviewMode(true);
wv.getSettings().setUseWideViewPort(true);
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); //loads online website when no internet connection.
wv.loadUrl("https://prajwalwaingankar.wixsite.com/nivala");

您需要使用重写onReceivedSslError
尝试
webV.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progDailog.show();
view.loadUrl(url);
return true;
}
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler,
SslError error) {
handler.proceed();
}
@Override
public void onPageFinished(WebView view, final String url) {
progDailog.dismiss();
}
});

创建名为network_security_config.xml
的文件,
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<debug-overrides>
<trust-anchors>
<certificates src="system" />
</trust-anchors>
</debug-overrides>
</base-config>
<domain-config>
<domain includeSubdomains="true">example.com</domain>
<domain includeSubdomains="true">example.example.com</domain>
<trust-anchors>
<certificates src="@raw/mycert" />
<certificates src="system" />
</trust-anchors>
</domain-config>
在清单中,
<application .....
android:networkSecurityConfig="@xml/network_security_config"
</application>
并根据需要添加您的SSL

要根据新的安全策略正确处理SSL证书验证并避免Google拒绝应用程序,请更改代码以在服务器提供的证书满足您的期望时调用 SslErrorHandler.proceed()。调用SslErrorHandler.cancel()
webV.setWebViewClient(new WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
webV!!.loadUrl(url)
return true
}
override fun onReceivedSslError(
view: WebView, handler: SslErrorHandler,
error: SslError
) {
handler.proceed()
}
});

其简单而准确的解决方案是启用 DomStorage 并设置 setJavaScriptCanOpenWindowsAutomatically = true
WebView webView = findViewById(R.id.webView);
webView.getSettings().setDomStorageEnabled(true); // this
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); //and this
它会解决问题。
享受吧。
