Your execute menthod is not quite right. When you do: return new PluginResult(PluginResult.Status.OK,resultFunction); that effectively returns nothing as a result. Instead you need to do: PluginResult r = new PluginResult(PluginResult.Status.NO_RESULT); r.setKeepCallback(true); return r; which will tell the JS layer that there is info coming soon. Then in your onActivityResult method you need to call: this.success(new PluginResult(PluginResult.Status.OK, msg), this.callbackId); and you should get your result correctly. Check out the:
有问题的代码，参考上面修改
Hi, i'm trying to pass a value from my Android java plugin to javascript in index.html. This is my code : PluginWrapper.js var PluginWrapper = function() { }; PluginWrapper.prototype.crop = function (name, win, fail){ console.log("Prima di execute!"); return PhoneGap.exec(win,fail,"PluginWrapper","crop",[name]); }; PhoneGap.addConstructor(function() { PhoneGap.addPlugin('PluginWrapper',new PluginWrapper()); }); PluginWrapper.java package it.Prova; import org.json.JSONArray; import com.phonegap.api.Plugin; import com.phonegap.api.PluginResult; import android.content.Intent; import android.util.Log; public class PluginWrapper extends Plugin{ private String resultFunction = null; @Override public PluginResult execute(String arg0, JSONArray arg1, String arg2) { Log.v("PLUGIN","PLUGIN EXECUTE"); Start(""); return new PluginResult(PluginResult.Status.OK,resultFunction); } public String Start(String name){ Log.v("START","START"); Intent intent = new Intent(this.ctx,PluginActivity.class); this.ctx.startActivityForResult((Plugin) this, intent, 0); return "OK"; } public void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent); if (requestCode == 0){ String msg = intent.getStringExtra("returnedData"); Log.v("FLAG","IN WRAPPER " + msg); resultFunction = msg; } } } PluginActivity.java package it.Prova; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.widget.Button; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; public class PluginActivity extends Activity{ private Button btn; private int flag = 0; private Intent intentNew = null; private Context context = this; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); intentNew = this.getIntent(); btn = (Button) findViewById(R.id.button1); btn.setOnClickListener(new OnClickListener(){ public void onClick(View v) { flag = 1; Log.v("FLAG","1 IN PLUGIN"); intentNew.putExtra("returnedData", Integer.toString(flag)); if (getParent() == null) { setResult(RESULT_OK, intentNew); } else { getParent().setResult(RESULT_OK, intentNew); } finish(); } }); } } index.html <!DOCTYPE HTML> <html> <head> <title>PhoneGap</title> <script type="text/javascript" charset="utf-8" src="phonegap-1.3.0.js"></script> <script type="text/javascript" charset="utf-8" src="PluginWrapper.js"></script> <script type="text/javascript" charset="utf-8"> function onLoad(){ document.addEventListener("deviceready", onDeviceReady, true); } function onDeviceReady() { //alert("OK"); } function getStart() { //window.plugins.PluginWrapper.crop("",function(r){console.log("Value in javascript " + r);}, // function(e){console.log("NO");} // ); var a = "vuoto"; a = window.plugins.PluginWrapper.crop(""); console.log("a = " + a); } </script> </head> <body onload="onLoad()"> <h1>Hello World</h1> <button onclick="getStart();">Start</button> <br> </body> </html> Attach the source code!

继承CordovaPluging的代码,Pluging继承CordovaPluging
public class WXPayPlugin extends CordovaPlugin { public static final String ACTION = "call"; private CallbackContext _callbackContext=null; @Override public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException { if (action.equals(ACTION)) { try { //下面两句最关键，利用intent启动新的Activity Intent intent = new Intent().setClass(cordova.getActivity(), Class.forName(args.getString(0))); this.cordova.startActivityForResult(this, intent, 1); _callbackContext=callbackContext; //下面三句为cordova插件回调页面的逻辑代码 PluginResult mPlugin = new PluginResult(PluginResult.Status.NO_RESULT); mPlugin.setKeepCallback(true); callbackContext.sendPluginResult(mPlugin); } catch (Exception e) { e.printStackTrace(); return false; } } return true; } //onActivityResult为第二个Activity执行完后的回调接收方法 @Override public void onActivityResult(int requestCode, int resultCode, Intent intent){ switch (resultCode) { //resultCode为回传的标记，我在第二个Activity中回传的是RESULT_OK case Activity.RESULT_OK: Bundle b=intent.getExtras(); //data为第二个Activity中回传的Intent String str=b.getString("change01");//str即为回传的值 _callbackContext.success(str); break; default: _callbackContext.error("fail"); break; } } }
