Cordova4.3.1 android 自定义插件（显示土司Toast）
自定义插件步骤：
1，自定义Toast插件类
package com.hl.hello.myPlugin;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
/**
* 显示土司插件
* @author yuhailong
*
*/
public class Toast extends CordovaPlugin {</p><p>
@Override
public boolean execute(String action, JSONArray args,
CallbackContext callbackContext) throws JSONException {
if("showToast".equals(action)){
showToast(args.getString(0), args.getInt(1));
}
callbackContext.success();
return true;
}</p><p> private void showToast(String text,int type){
CordovaInterface cordova = this.cordova;
if(type==1){
android.widget.Toast.makeText(cordova.getActivity(), text, 1).show();
}else{
android.widget.Toast.makeText(cordova.getActivity(), text, 0).show();
}
}
}
</p>
2，在res/xml/config.xml文件中增加插件配置
<feature name="WebToast"> <param name="android-package" value="com.hl.hello.myPlugin.Toast"/> </feature>
3，在asserts/www/plugins/目录下插件自己的插件js文件
如：asserts/www/plugins/com.hl.hello.myPlugin/toast.js
<p>cordova.define("com.hl.hello.myPlugin.Toast", function(require, exports, module) { /*

*
*/</p><p>var exec = require('cordova/exec');</p><p>/**
* Provides access to notifications on the device.
*/</p><p>module.exports = {</p><p>
/**
* Causes the device to beep.
* On Android, the default notification ringtone is played "count" times.
*
* @param {Integer} type The Toast type.
*/
showToast: function(content,type) {
exec(null, null, "WebToast", "showToast", [content,type]);
}
};</p><p>});
</p>
4,添加土司插件js配置信息
在assets/www/cordova_plugins.js文件中添加如下信息：
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [
{
"file": "plugins/org.apache.cordova.geolocation/www/geolocation.js",
"id": "org.apache.cordova.geolocation.geolocation",
"clobbers": [
"navigator.geolocation"
]
},
//增加插件js位置描述及调用对象 ，调用时将通过 navigator.webtoast.showToast()方法显示土司
<span style="color:#ff6666;">{
"file": "plugins/com.hl.hello.myPlugin/toast.js",
"id": "com.hl.hello.myPlugin.Toast",
"clobbers": [
"navigator.webtoast"
]
}</span>
];
});
5，代码调用
<p>var myToast = {</p><p> showToast: function(text,type){
navigator.webtoast.showToast(text,type);
}
};</p><p>myToast.showToast("你好，我是Toast.",1);</p>
toast.js中的方法解释：
exec(null, null, "WebToast", "showToast", [content,type]);
1，成功回调
2, 失败回调
3，插件名称 在res/xml/config.xml文件中指定
4，方法名称
5，方法参数
Toast.java类中的方法解释：
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
1，方法名称 对应exec 参数4
2，方法参数集合 对应exec 参数5
3，做回调相关操作
