[英]Android Keyboard Replacement Web-view
Is it possible to embed a web-view into an android keyboard replacement app? 是否可以将网络视图嵌入到Android键盘替换应用程序中?
I have an interface written in javascript, and would like to embed that into an android keyboard replacement app. 我有一个用javascript编写的界面,并希望将其嵌入到Android键盘替换应用程序中。 It will need to be able to detect touch events, and send text strings back to the native UI from the web-view. 它需要能够检测触摸事件,并从Web视图将文本字符串发送回本机UI。
I have searched google for this, but can not find any onformation on how to create web-view in keyboard replacement app. 我已经搜索了谷歌这个,但无法找到有关如何在键盘替换应用程序中创建Web视图的任何信息。

Yes. 是。 In short. 简而言之。 Not a great idea but technically feasible. 不是一个好主意,但技术上可行。 Let me walk you through a quick sample project, adapted from the SoftKeyboard sample included with the android SDK. 让我向您介绍一个快速示例项目,该项目改编自android SDK附带的SoftKeyboard示例。 Now there are a number of other technical issues to tackle but this should provide you with a basic starting point.... 现在还有许多其他技术问题需要解决,但这应该为您提供一个基本的起点....
For starters, lets create a basic layout to use as our keyboard: 首先,让我们创建一个基本布局作为我们的键盘使用:
\\res\\layout\\input.xml: \\水库\\布局\\ input.xml中:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<WebView
android:id="@+id/myWebView"
android:layout_width="match_parent"
android:layout_height="600dp"
/>
</FrameLayout>
this is required by android to accept our IME 这是android要求接受我们的IME
\\res\\xml\\method.xml: \\水库\\ XML \\ method.xml:
<?xml version="1.0" encoding="utf-8"?>
<input-method xmlns:android="http://schemas.android.com/apk/res/android" />
now onto our manifest \\AndroidManifest.xml 现在进入我们的manifest \\ AndroidManifest.xml
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.softkeyboard">
<uses-sdk android:minSdkVersion="13" android:targetSdkVersion="13" />
<uses-permission android:name="android.permission.INTERNET" />
<application android:label="SoftKeyboard">
<service
android:name="SoftKeyboard"
android:permission="android.permission.BIND_INPUT_METHOD"
>
<intent-filter>
<action android:name="android.view.InputMethod" />
</intent-filter>
<meta-data android:name="android.view.im" android:resource="@xml/method" />
</service>
</application>
</manifest>
obviously the uses-sdk
and user-permission
are up to the app and not required by this code (i'm not using any internet files here, but you could, i tested it and it worked...) 很明显, uses-sdk
和user-permission
是由应用程序决定的,而不是这个代码所要求的(我这里没有使用任何互联网文件,但你可以,我测试了它并且它有效...)
now define a simple keyboard \\src...\\SoftKeyboard.java: 现在定义一个简单的键盘\\ src ... \\ SoftKeyboard.java:
package com.example.android.softkeyboard;
import android.inputmethodservice.InputMethodService;
import android.inputmethodservice.KeyboardView;
import android.view.View;
import android.webkit.WebView;
public class SoftKeyboard extends InputMethodService implements KeyboardView.OnKeyboardActionListener {
private WebView myWebView = null;
@Override
public View onCreateInputView() {
View view = getLayoutInflater().inflate(R.layout.input, null);
myWebView = (WebView) view.findViewById(R.id.myWebView);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.addJavascriptInterface(jsInterface, "android");
return view;
}
private Object jsInterface = new Object() {
@SuppressWarnings("unused")
public void sendKeys() {
getCurrentInputConnection().setComposingText("how do ya like me now?", 1);
}
};
@Override
public void onWindowShown() {
super.onWindowShown();
myWebView.loadUrl("file:///android_asset/keyboard_test.html");
}
@Override
public void onKey(int primaryCode, int[] keyCodes) {}
@Override
public void onPress(int primaryCode) {}
@Override
public void onRelease(int primaryCode) {}
@Override
public void onText(CharSequence text) {}
@Override
public void swipeDown() {}
@Override
public void swipeLeft() {}
@Override
public void swipeRight() {}
@Override
public void swipeUp() {}
}
here we basically create a webview then populate it from a asset file and bind a simple interface to it after enabling javascript 这里我们基本上创建一个webview,然后从资产文件填充它,并在启用javascript后绑定一个简单的界面
here's the asset html: *\\assets\\keyboard_test.html* 这是资产html: * \\ assets \\ keyboard_test.html *
<!DOCTYPE html>
<html>
<head>
<title>test</title>
<style>
button {
display:block;
margin:300px auto;
width:400px;
padding:60px;
}
</style>
</head>
<body>
<button onclick="android.sendKeys()">yeah buddy!</button>
</body>
</html>
and that's it, run it and you'll get a keyboard with a single button and when you push it the javascript will send text into the input composer... 就是这样,运行它,你会得到一个带有单个按钮的键盘,当你按下它时,javascript会将文本发送到输入作曲家......
hope that helps -ck 希望有所帮助
