通过Cordova进行活动回调

Question

我有一个名为“签名”的活动，我是从CordovaPlugin调用的；

插件.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");
             }
     }

签名库

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”函数会立即自动调用它。我无法通过finishWithResult从Activity回调。任何建议。谢谢

首先，缺少一些代码（ 执行 方法的返回语句），您必须告诉android / cordova-plugin等待，直到使用 NO_RESULT 和
PlugInResult 的 setKeepCallback 将结果发送回您的webview-app 为止 ，否则cordova /
android希望在 execute -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());
}

在此处（针对您的插件类）和此处（针对您的签名类）有一个示例。
