Question

我正在使用Retrofit2进行Api通话。在改造Api响应时，我试图在收到错误消息时显示Toast。但该应用程序因抛出以下异常而崩溃。它工作正常，直到昨天。

以下是Retrofit Api电话的代码片段。

Api.instance().login(requestLogin).enqueue(new Callback<Login>() {
        @Override
        public void onResponse(Call<Login> call, Response<Login> response) {

            if(response.code() == 200){
                // Success
            }else if(response.code() == 401) {
                Error error = ErrorHandler.parse(response);
                String message = error!=null?error.getMessage():"";
                Toast.makeText(getActivity(), message, Toast.LENGTH_LONG).show();//I am getting error in this line.
            }else{
                Toast.makeText(mActivity, "Authentication failed. Check your credentials and try again.", Toast.LENGTH_LONG).show();
            }
        }

        @Override
        public void onFailure(Call<Login> call, Throwable t) {
            mProgressContainer.setVisibility(View.GONE);

        }
    });

android中的每个UI更新都必须在UI线程中执行：

mActivity.runOnUiThread(new Runnable() {
    @Override
    public void run() {
        Toast.makeText(mActivity, "Authentication failed. Check your credentials and try again.", Toast.LENGTH_LONG).show();
    }
});

Android应用程序崩溃，同时在改装响应中显示吐司
