Android WebView文字大小调整及页面缩放调整

初学者使用webview难免会面对页面缩放，展示与预期不符的问题，这里有几个处理方案：

方案一、通过屏幕密度调整分辨率

        WebSettings settings = mWebView.getSettings();
       int screenDensity = getResources().getDisplayMetrics().densityDpi;
        WebSettings.ZoomDensity zoomDensity = WebSettings.ZoomDensity.MEDIUM;
        switch (screenDensity) {
            case DisplayMetrics.DENSITY_LOW:
                zoomDensity = WebSettings.ZoomDensity.CLOSE;
                break;
            case DisplayMetrics.DENSITY_MEDIUM:
                zoomDensity = WebSettings.ZoomDensity.MEDIUM;
                break;
            case DisplayMetrics.DENSITY_HIGH:
                zoomDensity = WebSettings.ZoomDensity.FAR;
                break;
        }
        settings.setDefaultZoom(zoomDensity);

方案二、设置自适应

        settings.setUseWideViewPort(true); 
        settings.setLoadWithOverviewMode(true);

另外，WebView中文字大小也可以进行调整，通过以下方法可以调整文字大小：文章源自IT老刘-https://wp.itlao6.com/687.html

        settings.setTextZoom(100);

中间int参数是指字体与原大小的百分比。文章源自IT老刘-https://wp.itlao6.com/687.html 文章源自IT老刘-https://wp.itlao6.com/687.html
