Android WebView background color
提问by Vervatovskis
I am adding to my layout a WebView to display justified text. I want to set the background of the WebView to be transparent to appear like a textView. Here's what I did:
我在我的布局中添加了一个 WebView 来显示对齐的文本。我想将 WebView 的背景设置为透明以显示为 textView。这是我所做的：
WebView synopsis;
synopsis=(WebView)findViewById(R.id.synopsis);
synopsis.setBackgroundColor(0x00000000);
It works on the emulator, but when I run the application on my device it doesn't work: what I get is a white background.
它适用于模拟器，但是当我在我的设备上运行应用程序时它不起作用：我得到的是白色背景。
String textTitleStyling = "<head><style>* {margin:0;padding:0;font-size:20; text-align:justify; color:#FFFFFF;}</style></head>";
String titleWithStyle = textTitleStyling + "<body><h1>" + movie.synopsis + "</h1></body>";
synopsis.loadData(textTitleStyling + movie.synopsis, "text/html", "utf-8");
synopsis = (WebView) findViewById(R.id.synopsis);
synopsis.getSettings();
synopsis.setBackgroundColor(0);

You must put this in the XML code :
你必须把它放在 XML 代码中：
android:background="@android:color/transparent"
for your web view like this for example :
对于像这样的网络视图，例如：
<WebView
android:id="@+id/MyWebView"
android:layout_width="fill_parent"
android:layout_height="62dp"
android:background="@android:color/transparent"
android:scrollbars="none" />
and after this you must go to Java code and write this before loadUrl :
在此之后，您必须转到 Java 代码并在 loadUrl 之前编写此代码：
yourWebView.setBackgroundColor(Color.TRANSPARENT);

Did you load the css in ur webview?
你在你的 webview 中加载了 css 吗？
Something like:
就像是：
synopsis.loadData(textTileStyling, "text/html", "UTF-8");
or
或者
synopsis.loadDataWithBaseURL("", textTileStyling, "text/html", "UTF-8", "");

Your html code sets everything to white
您的 html 代码将所有内容设置为白色
Replace:
代替：
String textTitleStyling = "<head><style>* {margin:0;padding:0;font-size:20; " +
"text-align:justify; color:#FFFFFF;}</style></head>";
String titleWithStyle = textTitleStyling + "<body><h1>" + movie.synopsis +
"</h1></body>";
synopsis.loadData(textTitleStyling + movie.synopsis, "text/html", "utf-8");
synopsis = (WebView) findViewById(R.id.synopsis);
synopsis.getSettings();
synopsis.setBackgroundColor(0);
With:
和：
This excludes color from header style and applies the rest of the style only to body element
这从标题样式中排除颜色并将样式的其余部分仅应用于正文元素
String textTitleStyling = "<head><style>body{margin:0;padding:0;font-size:20; " +
"text-align:justify;}</style></head>";
String titleWithStyle = textTitleStyling + "<body><h1>" + movie.synopsis +
"</h1></body>";
synopsis.loadData(titleWithStyle, "text/html", "utf-8");
synopsis = (WebView) findViewById(R.id.synopsis);
synopsis.getSettings();
synopsis.setBackgroundColor(0);
EDIT: fixed html
编辑：固定 html
