問題描述

android webview 顯示其字體的默認字體系列是什麼？ (What is the default font family taken by android webview to show its fonts?)

我在 Webview 上以 loadData 方法顯示我的內容

  webview.loadData(WS.welcome_header_text,"text/html","UTF‑8");

Here my WS.welcome_header_text =  <div style="text‑align: center;"><span style="color: rgb(255, 255, 255); font‑size: x‑large; background‑color: transparent;">Please share your feedback with us</span></div>

我的後端 API 沒有指定字體系列，但 我想知道什麼字體系列我的 android web 視圖默認採用。

當它顯示內容時“請與我們”在上面的屏幕截圖中。

參考解法

方法 1:

WebView has provided us with the methods to check the default fonts like ‑

1. webview.getSettings().getStandardFontFamily()
2. webview.getSettings().getFixedFontFamily()

and As WebView Safe fonts Suggested, My default fonts which are applying, I get it through StandardFontFamily(sans‑serif) font‑family in my case and Arial/Verdana fonts in particular.

方法 2:

Give your span tag an ID say my‑text and run the following code

String js = "(function(){var element = document.getElementById( 'my‑text' );return window.getComputedStyle( element, null ).getPropertyValue('font‑family');})()";

webView.evaluateJavascript(js, new ValueCallback<String>() {
    @Override
    public void onReceiveValue(String s) {
        Log.d("FontFamily", s); 
    }
});
