如何在asyntask里面的android中创建吐司

Question

我这样做了：

doInBackground(String... prams){
    Toast.makeText(getApplicationContext(),
                            "Server too busy. Please try after sometime.",
                            Toast.LENGTH_LONG).show();}

获取错误。请帮忙。

Answer 1

您无法在doInBackground中更新UI。请执行此操作以显示吐司

getActivity().runOnUiThread(new Runnable() {

            @Override
            public void run() {
                Toast.makeText(getApplicationContext(),
                        "Server too busy. Please try after sometime.",
                        Toast.LENGTH_LONG).show();

            }
        });

它将解决您的问题
