用action.VIEW创建简单的WebView

<WebView
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

WebView webView = findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true); // 启用JavaScript支持
webView.loadUrl("https://www.example.com"); // 加载指定URL的网页

<uses-permission android:name="android.permission.INTERNET" /> // 添加网络访问权限

<activity android:name=".WebViewActivity">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

public class WebViewActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_webview);

        Intent intent = getIntent();
        Uri data = intent.getData();
        String url = data.toString();

        WebView webView = findViewById(R.id.webview);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(url);
    }
}
