android-如何为ionic创建cordova插件
作者:互联网
我是插件创建的新手,我已经搜索了如何创建cordova插件,并且得到了此链接https://blogs.oracle.com/mobile/entry/introduction_to_custom_cordova_plugin
通过单击此链接,我创建了一个警报插件,但是无法在ionic中使用它,这是放在src / android文件夹下的Alert.java代码.
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.PluginResult;
import org.apache.cordova.CordovaArgs;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class Alert extends CordovaPlugin {
@Override
ublic boolean execute(String action, CordovaArgs args, CallbackContext callbackContext)
throws JSONException {
if (action.equals("alert")) {
alert(args.getString(0), args.getString(1), args.getString(2), callbackContext);
return true;
}
return false;
}
private synchronized void alert(final String title,
final String message,
final String buttonLabel,
final CallbackContext callbackContext) {
new AlertDialog.Builder(cordova.getActivity())
.setTitle(title)
.setMessage(message)
.setCancelable(false)
.setNeutralButton(buttonLabel, new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int which) {
dialogInterface.dismiss();
callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK, 0));
}
})
.create()
.show();
}
}
这是放在www文件夹下的alert.js代码
module.exports = {
alert: function(title, message, buttonLabel, successCallback) {
cordova.exec(successCallback,null,"Alert","alert",[title, message, buttonLabel]);
}
};
plugin.xml看起来像这样
<?xml version="1.0" encoding="UTF-8"?>
<plugin xmlns="http://www.phonegap.com/ns/plugins/1.0"
xmlns:android="http://schemas.android.com/apk/res/android"
id="cordova-plugin-my-alert"
version="0.0.2">
<name>Alert</name>
<description>A Cordova plugin that displays an alert popup dialog</description>
<license>Apache 2.0</license>
<js-module src="www/Alert.js" name="Alert">
<clobbers target="Alert" />
</js-module>
<!-- android -->
<platform name="android">
<config-file target="res/xml/config.xml" parent="/*">
<feature name="Alert">
<param name="android-package" value="com.acme.plugin.alert.Alert" />
</feature>
</config-file>
<source-file src="src/android/Alert.java" target-dir="src/com/acme/plugin/alert" />
</platform>
</plugin>
请帮我哪里错了.
解决方法:
我通过在警报功能中添加故障回调而不是null来解决以上错误,并且我也错过了Alert.java类中的程序包名称
