我在a .jpg
中加载WebView
。我的问题是我找到了这个:Android WebView, Scaling Image to fit the screen
它对我不起作用。
这是我的代码:
Display display = getWindowManager().getDefaultDisplay();
int width= display.getWidth();
Toast.makeText(getApplicationContext(), ""+width, Toast.LENGTH_LONG).show();
String html = "<html><head><title>Example</title><meta name=\"viewport\"\"content=\"width="+width+", initial-scale=0.65 \" /></head>";
html+= "<body><img width=\""+width+"\"<img src=\""+"image.jpg"+"\" /></body></html>";
aboutText.loadDataWithBaseURL("file:///android_res/drawable/", html, "text/html","UTF-8" , null);

这对我来说不起作用,因为我有高分辨率手机。
试试这个,它对我有用,
webView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);

在将HTML加载到Web视图之前,您可以设置img标记的样式。请参阅以下代码
WebView content = (WebView) findViewById(R.id.webView1);
String head = "<head> <style>img{display: inline;height: auto;max-width: 100%;}</style> <style>body {font-family: 'Roboto'; }</style></head>";
content.loadDataWithBaseURL(null, head + post.getContent(), "text/html", "UTF-8", null);

你是html图片标签错误检查下面的代码:
Display display = getWindowManager().getDefaultDisplay();
int width= display.getWidth();
Toast.makeText(getApplicationContext(), ""+width, Toast.LENGTH_LONG).show();
String html = "<html><head><title>Example</title><meta name=\"viewport\"\"content=\"width="+width+", initial-scale=0.65 \" /></head>";
html+= "<body><img width=\""+width+"\" src=\""+"image.jpg"+"\" /></body></html>";
aboutText.loadDataWithBaseURL("file:///android_res/drawable/", html, "text/html","UTF-8" , null);
您的html字符串格式错误的图片标记如下代码:
String html = "<html><head><title>Example</title><meta name=\"viewport\"\"content=\"width="+width+", initial-scale=0.65 \" /></head>";
html+= "<body><img width=\""+width+"\"<img src=\""+"image.jpg"+"\" /></body></html>";
格式化我的代码:
String html = "<html><head><title>Example</title><meta name=\"viewport\"\"content=\"width="+width+", initial-scale=0.65 \" /></head>";
html+= "<body><img width=\""+width+"\" src=\""+"image.jpg"+"\" /></body></html>";
