تحسين سلوك النقر على WebView
تنظيم صفحاتك في مجموعات
يمكنك حفظ المحتوى وتصنيفه حسب إعداداتك المفضّلة.
إذا كان تطبيقك يستخدم
WebView
لعرض محتوى الويب، ننصحك
بتحسين سلوك النقرات للأسباب التالية:
- لا تتوافق
WebView
مع مخططات عناوين URL المخصّصة
التي يمكن عرضها في الإعلانات إذا كانت وجهة النقرة تطبيقًا منفصلاً.
على سبيل المثال، قد يستخدم عنوان URL للنقر المؤدي إلى صفحة على Google Play market://
.
يقدّم هذا الدليل خطوات مقترَحة لتحسين سلوك النقر في عروض الويب على الأجهزة الجوّالة مع الحفاظ على محتوى عرض الويب.
المتطلبات الأساسية
التنفيذ
اتّبِع الخطوات التالية لتحسين سلوك النقر في WebView
مثيلك:
ألغِ shouldOverrideUrlLoading()
في WebViewClient
.
يتم استدعاء هذه الطريقة عندما يكون عنوان URL على وشك التحميل في
WebView
الحالي.
تحديد ما إذا كان سيتم تجاهل سلوك عنوان URL للنقرة
يتحقّق مثال الرمز ممّا إذا كان النطاق الحالي مختلفًا عن النطاق المستهدف. هذه مجرد طريقة واحدة، إذ يمكن أن تختلف المعايير التي تستخدمها.
حدِّد ما إذا كنت تريد فتح عنوان URL في متصفّح خارجي أو في علامات التبويب المخصّصة في Android أو في عرض الويب الحالي. يوضّح هذا الدليل كيفية فتح عناوين URL خارج الموقع الإلكتروني من خلال تشغيل "علامات التبويب المخصّصة" في Android.
مثال على الرمز
أولاً، أضِف التبعية androidx.browser
إلى ملف build.gradle
على مستوى الوحدة، ويكون اسمه عادةً app/build.gradle
. يجب استيفاء الشرط التالي لاستخدام علامات التبويب المخصّصة:
dependencies {
implementation 'androidx.browser:browser:1.5.0'
}
يوضّح مقتطف الرمز التالي كيفية تنفيذ shouldOverrideUrlLoading()
:
Java
public class MainActivity extends AppCompatActivity {
private WebView webView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ... Register the WebView.
webView = new WebView(this);

webSettings.setJavaScriptEnabled(true);
webView.setWebViewClient(
new WebViewClient() {
// 1. Implement the web view click handler.
@Override
public boolean shouldOverrideUrlLoading(
WebView view,
WebResourceRequest request) {
// 2. Determine whether to override the behavior of the URL.
// If the target URL has no host and no scheme, return early.
if (request.getUrl().getHost() == null && request.getUrl().getScheme() == null) {
return false;
}
// Handle custom URL schemes such as market:// by attempting to
// launch the corresponding application in a new intent.
if (!request.getUrl().getScheme().equals("http")

Log.d("TAG", "Failed to load URL with scheme:" + request.getUrl().getScheme());
