从cordova的活动回调

我有一个名为’Signature’的活动，我从CordovaPlugin调用它;

Plugin.java

public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException { Intent i = new Intent(context, Signature.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); cordova.startActivityForResult(this,i,90); } public void onActivityResult(int requestCode, int resultCode, Intent intent) { Log.d(TAG, "activity result in plugin: requestCode(" + requestCode + "), resultCode(" + resultCode + ")"); if(requestCode == 90) { if (resultCode == this.cordova.getActivity().RESULT_OK) { Bundle res = intent.getExtras(); String result = res.getString("results"); Log.d("FIRST", "result:"+result); this.callbackContext .success(result.toString()); } else { this.callbackContext.error("Error"); } } 

Signature.java

 private void finishWithResult(String result,int status) { Bundle conData = new Bundle(); conData.putString("results", result); Intent intent = new Intent(); intent.putExtras(conData); setResult(status, intent); finish(); } 

但是，当我调用“cordova.startActivityForResult”函数时，“onActivityResult”立即调用它自己。 我无法通过finishWithResult从Activity回调。 任何建议。 谢谢

首先，有一些代码丢失（ 执行 -method的return语句），你必须告诉android / cordova-plugin等到结果发送回你的webview-app使用NO_RESULT和PluginResult的setKeepCallback否则cordova / android希望在执行 -method完成后立即获得结果：

Plugin.java：

 public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException { PluginResult r = new PluginResult(PluginResult.Status.NO_RESULT); r.setKeepCallback(true); callbackContext.sendPluginResult(r); Intent i = new Intent(context, Signature.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); cordova.startActivityForResult(this,i,90); return true; } public void onActivityResult(int requestCode, int resultCode, Intent intent){ // here is your former code ... ... // at last call sendPluginResult this.callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK, result.toString())); // when there is no direct result form your execute-method use sendPluginResult because most plugins I saw and made recently (Reminder) prefer sendPluginResult to success/error // this.callbackContext.success(result.toString()); } 

这里有一个例子（对于你的插件类）和这里 （对于你的签名类）。
