Cordova插件回调在第二个插件调用后收到 [英] Cordova plugin callback received after second plugin call

问题描述

我创建了一个cordova插件（3.3.0），它启动一个活动并等待结果。但回调（简单的警报）不会调用，直到lauch插件第二次。这是代码：

  public boolean execute（String action，final JSONArray args，final CallbackContext cbc）throws JSONException 
 {
 this.callbackContext = cbc; 
 
 try 
 {
 Intent i = new Intent（cordova.getActivity（），ActivityCamera.class）; 
 
 this.cordova.setActivityResultCallback（PhotoMokoPlugin.this）; 
 this.cordova.startActivityForResult（PhotoMokoPlugin.this，i，0）; 
 
 PluginResult pr = new PluginResult（PluginResult.Status.NO_RESULT）; 
 pr.setKeepCallback（true）; 
 callbackContext.sendPluginResult（pr）; 
 return true; 
} 
 catch（JSONException e）
 {
 callbackContext.sendPluginResult（new PluginResult（PluginResult.Status.JSON_EXCEPTION））; 
 return false; 
} 
} 
 
 @Override 
 public void onActivityResult（int requestCode，int resultCode，Intent intent）
 {
 super.onActivityResult requestCode，resultCode，intent）; 
 
 try 
 {
 callbackContext.success（json.toString（））; //如果成功或错误不重要
} 
 catch（JSONException e）
 {
 callbackContext.sendPluginResult（new PluginResult（PluginResult.Status.ERROR））; 
} 
} 
  

仅限ActivityCamera setResult 与新的意图 avec finish（）;

例如：如果我点击一个调用插件的按钮，什么也没有发生。我再次点击，显示提醒消息，没有什么（通常是另一个提醒）...

你有什么想法吗？

告诉我是否需要更多代码。

编辑：更新Cordova没有解决问题。 / p>

编辑2：问题似乎来自此代码：

  @Override 
 public void onWindowFocusChanged（boolean hasFocus）{
 super.onWindowFocusChanged（hasFocus）; 
 if（hasFocus）
 {
 getWindow（）。getDecorView（）。setSystemUiVisibility（View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
 | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
 | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 
 | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION 
 | View.SYSTEM_UI_FLAG_FULLSCREEN 
 | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY）; 
} 
} 
  

如果我删除它，回调被称为第一个时间。是否有问题？

解决方案

我在这种情况下也遇到了麻烦。

在我的例子中，插件是从iframe内容中绑定点击处理程序的标签触发的。
当我将一个标签和点击处理程序移动到父文档时，问题就解决了。

你可以试试这样吗？

I've created a cordova plugin (3.3.0), which launch an activity and waits for a result. But the callback (simple alert) isn't call until a lauch the plugin a second time. Here is the code :

public boolean execute(String action, final JSONArray args, final CallbackContext cbc) throws JSONException
{
    this.callbackContext = cbc;

    try
    {
        Intent i = new Intent(cordova.getActivity(), ActivityCamera.class);

        this.cordova.setActivityResultCallback(PhotoMokoPlugin.this);
        this.cordova.startActivityForResult(PhotoMokoPlugin.this, i, 0);

        PluginResult pr = new PluginResult(PluginResult.Status.NO_RESULT);
        pr.setKeepCallback(true);
        callbackContext.sendPluginResult(pr);
        return true;
    }
    catch (JSONException e)
    {
        callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.JSON_EXCEPTION));
        return false;
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    super.onActivityResult(requestCode, resultCode, intent);

    try
    {
        callbackContext.success(json.toString()); // Doesn't matter if success or error
    }
    catch (JSONException e)
    {
        callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.ERROR));
    }
}

The ActivityCamera only setResult with a new Intent avec finish();

For example : If I click on a button which call the plugin, nothing happens. I click a second time, the alert message is displayed and nothing more (normally another alert)...

Do you have any idea ?

Tell me if more code is needed.

EDIT : Updating Cordova didn't solved the problem.

EDIT 2 : The problem seems to come from this code :

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus)
    {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }
}

If I remove it, the callback is called the first time. Is there an issue ?

解决方案

I was in trouble in this situation also.

In my case, plugin is triggered from a tag, in which click handler is bound, in iframe content. When I moved a tag and click handler to parent document, problems are solved.

Can you try like these?
