Just Use It *{margin:0px; padding:0px} Add In Your Style Sheet And Check Once

Just Use It * {margin：0px;填充：0px}添加样式表并检查一次

  *{margin:0px; padding:0px}
    body,html{padding:0px;margin:0px;}
 <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

By Default HTML web pages have a padding and margin of 10px; You have to set in your head section or or css file:

默认情况下，HTML网页的填充和边距为10px;您必须在头部或css文件中设置：

<style type="text/css">
  html, body {
  width:100%;
  height: 100%;
  margin: 0px;
  padding: 0px;
  }

It's work for me. Hope it will help you :)

or you can try another one:

或者你可以尝试另一个：

Replace your tag with this one:

用这个替换你的标签：

<body style='margin:0;padding:0;'>

Here's another tip for images in a webview: add a styling that fits images in the width of the screen. Works great on all screen sizes:

这是webview中图像的另一个提示：添加适合屏幕宽度图像的样式。适用于所有屏幕尺寸：

<style type='text/css'>
      img {max-width: 100%;height:initial;} div,p,span,a {max-width: 100%;}
   </style>

If using the css doesn't solve your issue, you can try using a TextView with fromHtml instead of using a webview:

如果使用css无法解决您的问题，您可以尝试使用带有fromHtml的TextView而不是使用webview：

TextView myTextView = (TextView) view.findViewById(R.id.my_textview);
Spanned textviewHtml;

//Note : fromHtml needs a display flag as second argument from API 24
if (Build.VERSION.SDK_INT >= 24) {
    textviewHtml= Html.fromHtml(yourHtmlHere, Html.FROM_HTML_MODE_COMPACT);
}
else {
    textviewHtml= Html.fromHtml(yourHtmlHere);
}

myTextView.setText(textviewHtml);

For more options on fromHtml you can refer to https://developer.android.com/reference/android/text/Html.html
