Question

有没有人知道为什么下面的吐司没有出现？打印日志，同一功能中的另一个吐司也正常工作

    if (searchType.equals("ByName")){
        // get the extra from the intent:
        String query = intent.getStringExtra("query");      
            if (!searchByName(query)){
                Toast.makeText(getApplicationContext(), "No results for this search",
                        Toast.LENGTH_LONG).show();  
                Log.d(TAG, "return status true/false -->" + searchByName(query));
            }           
    }

任何帮助将不胜感激

我正在附加日志，我不得不删除一些行，因为它太长了... 这是日志：

我认为它是Android Framework中的一个错误。每当您尝试从应用程序主线程中制作或显示Toast时。最常使用IntentService。始终确保您的Toast进入应用程序主线程。

请查看以下解决方法。所有代码都在您的服务中。

处理程序声明。

Handler handler = null;

并在您的服务的构造函数中

handler  = new Handler();

调用显示Toast的方法。

public void showToast(String message, Context context){
        handler.post(new CustomToast(message, context));
    }

CostomToast

private class CustomToast implements Runnable{
          String mText;
          Context mContext;

  public CustomToast(String text, Context context){
            mText = text;
            mContext = context;
  }

   public void run(){
            Toast.makeText(mContext, mText, Toast.LENGTH_LONG).show();
  }

toast消息在服务意图中不起作用
