6.通过字符串拼凑的html页面显示:

Java代码

publicvoidsimpleJsClick() {

WebView webView = (WebView) findViewById(R.id.webview);

String html = ""

+ "

"

+ "图书封面
"

+ "

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"+""+""+"";

webView.loadDataWithBaseURL(null, html,"text/html","utf-8",null);

webView.getSettings().setJavaScriptEnabled(true);

webView.setWebChromeClient(newWebChromeClient());

}

public void simpleJsClick() {

WebView webView = (WebView) findViewById(R.id.webview);

String html = ""

+ "

"

+ "图书封面
"

+ "

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

"

+ "

" + "" + "" + "";

webView.loadDataWithBaseURL(null, html, "text/html", "utf-8", null);

webView.getSettings().setJavaScriptEnabled(true);

webView.setWebChromeClient(new WebChromeClient());

}

7.在同种分辨率的情况下,屏幕密度不一样的情况下,自动适配页面:

Java代码

DisplayMetrics dm = getResources().getDisplayMetrics();

intscale = dm.densityDpi;

if(scale ==240) {//

webView.getSettings().setDefaultZoom(ZoomDensity.FAR);

} elseif(scale ==160) {

webView.getSettings().setDefaultZoom(ZoomDensity.MEDIUM);

} else{

webView.getSettings().setDefaultZoom(ZoomDensity.CLOSE);

}

DisplayMetrics dm = getResources().getDisplayMetrics();

int scale = dm.densityDpi;

if (scale == 240) { //

webView.getSettings().setDefaultZoom(ZoomDensity.FAR);

} else if (scale == 160) {

webView.getSettings().setDefaultZoom(ZoomDensity.MEDIUM);

} else {

webView.getSettings().setDefaultZoom(ZoomDensity.CLOSE);

}

8.判断加载的页面URL地址是否正确:

Java代码

if(URLUtil.isNetworkUrl(url)==true)

if(URLUtil.isNetworkUrl(url)==true)

9.设置WebView的一些缩放功能点:

Java代码

webView.getSettings().setJavaScriptEnabled(true);

webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

webView.setHorizontalScrollBarEnabled(false);

webView.getSettings().setSupportZoom(true);

webView.getSettings().setBuiltInZoomControls(true);

webView.setInitialScale(70);

webView.setHorizontalScrollbarOverlay(true);
