我们怎样才能创建的Android iPhone类似的微调？ [英] How can we create iPhone-like spinners in android?
问题描述
默认iPhone上的微调看起来很多比Android好。它看起来像至少一个Android应用程序（UrbanSpoon）已经能够复制这种控制，这是真棒：的http：// www.urbanspoon.com/android
Default spinners on the iPhone look a lot better than on Android. It looks like at least one Android app (UrbanSpoon) has been able to replicate this control, and it's awesome: http://www.urbanspoon.com/android
任何人有关于如何创建这个任何想法？ code将是有益的。
Anyone have any ideas on how to create this? Code would be helpful.
推荐答案
如果您不需要为轨迹球的支持，那么所有这将是的WebView 以及一些小的调整，一些现有的 JavaScript代码模仿苹果的UIPickerView的创建应用程序是这样的。
If you don't need support for the trackball, then all it will take is WebView along with some minor tweaks to some existing JavaScript that impersonates Apple's UIPickerView to create applications like this.
大多数的辛勤工作已经做了利玛窦斯皮内利因此通过开始下载了code 然后将这些更改 spinningwheel.js 。他的code要弹出从与取消了屏幕下方的机械手，做按钮，所以我们需要修改几行来消除这种行为。
A majority of the hard work has been done by Matteo Spinelli so start by downloading his code and then apply these changes to spinningwheel.js. His code wants to pop up the picker from the bottom of the screen with cancel and done buttons so we need to modify a few lines to eliminate this behavior.

此外， index.html的，他提供的是不是你想要什么，因此这一个替换，然后复制HTML，CSS，JS和PNG文件到项目的资产目录。
Additionally, the index.html he provides isn't exactly what you want so replace it with this one and then copy the html, css, js, and png files into the assets directory of your project.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" href="spinningwheel.css" type="text/css" media="all" />
<script type="text/javascript" src="spinningwheel.js?v=1.4"></script>
<title></title>
<script type="text/javascript">
function getData() {
var results = SpinningWheel.getSelectedValues();
window.android.sendResults(results.values.join(' ') );
}
function notifyAndroid() {
window.android.readyForJavascript('');
}
</script>
</head>
<body onload="javascript:notifyAndroid()"></body>
</html>
创建活动，使JavaScript的一个web视图，并有回调它返回的选择。
Create an Activity that enables JavaScript in a WebView and has callbacks for it to return the selection.
public class FancySpinner extends Activity {
private WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.GetSelectedTimeButton))
.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
webView.loadUrl("javascript:getData()");
}
});
webView = (WebView) findViewById(R.id.WebView01);
webView.getSettings().setJavaScriptEnabled(true);
webView.addJavascriptInterface(new AndroidBridge(), "android");
webView.setVerticalScrollBarEnabled(false);
webView.loadUrl("file:///android_asset/index.html");
}
private class AndroidBridge {
public void sendResults(final String arg) {
Toast.makeText(FancySpinner.this, arg, Toast.LENGTH_SHORT).show();
}
public void readyForJavascript(final String arg) {
webView.loadUrl("javascript:SpinningWheel.addSlot({ " +
"1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6," +
"7: 7, 8: 8, 9: 9, 10: 10, 11: 11, 12: 12 });");
webView.loadUrl("javascript:SpinningWheel.addSlot({ " +
"1: 'AM', 2: 'PM'});");
webView.loadUrl("javascript:SpinningWheel.open();");
}
}
}
最后，修改你的布局，与它的高度适当设定一个web视图。
Finally, modify your layout so has a WebView with its height set appropriately.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
<WebView
android:id="@+id/WebView01"
android:background="#77CC0000"
android:layout_height="215dp"
android:layout_width="fill_parent"
android:focusable="false" />
<Button
android:text="Read Selected Time"
android:id="@+id/GetSelectedTimeButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
