我通过变量在Response中获取此html内容: String mresult=
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Lorem Ipsum</title>
</head>
<body style="width:300px; color: #00000; ">
<p><strong> About us</strong> </p>
<p><strong> Lorem Ipsum</strong> is simply dummy text .</p>
<p><strong> Lorem Ipsum</strong> is simply dummy text </p>
<p><strong> Lorem Ipsum</strong> is simply dummy text </p>
</body></html>
它无法加载webview,我必须尝试加载它像这样:
web.loadDataWithBaseURL(null, mresult, "text/html", "UTF-8", null);
仍webview显示空白页面.
在xml文件中:
<WebView
android:id="@+id/wV"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_margin="10dp"
android:background="@android:color/transparent"
android:cacheColorHint="#00000000" />
在活动中:
String mresult="Here my given data";
WebView web = (WebView)findViewById(R.id.wV);
web.setWebViewClient(new WebViewClient() …集成了这个库SlideDateTimePicker
码
new SlideDateTimePicker.Builder(getSupportFragmentManager())
.setListener(listener)
.setInitialDate(new Date())
.build()
.show();
错误

我想设置

以编程方式
txtarrow1.setBackgroundResource(R.drawable.arrow_blue);
但是这个没有用
这里参考开发者网站 和通话录音android 10 尝试录制音频文件并将其保存到其本地目录路径，我使用AccessibilityService来实现它在Android Q（10）中的录音 服务代码如下
