显示来自 BroadcastReceiver 的复杂 Toast

发布于 2024-08-08 15:27:00 字数 1111 浏览 11 评论 0原文

我想知道是否有人可以帮助我。我试图在收到短信时显示 toast 元素。这个 toast 应该包含一个布局，其中有一个图像（短信图标）和 2 个文本视图（发件人、消息）

如果我从活动中调用以下方法，它会按预期工作...

public void showToast(Context context, String name, String message) {
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.toast_sms,
                                   (ViewGroup) findViewById(R.id.toast_sms_root));

    TextView text = (TextView) layout.findViewById(R.id.toastsms_text);
    text.setText(message);

    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    toast.show();
}

但是，如果我尝试在以同样的方式从我的短信接收器中，我得到：

The method getLayoutInflater() is undefined for the type SmsReceiver
The method findViewById(int) is undefined for the type SmsReceiver
The method getApplicationContext() is undefined for the type SmsReceiver

有人可以告诉我如何从意图中做到这一点吗？我认为这个问题在某种程度上与跨线程有关，但是我不确定如何继续。我在网上看到了几个示例，但它们似乎要么使用已弃用的代码，要么只显示简单的文本

有人可以指出我正确的方向吗

非常感谢

I wonder if someone can help me. I'm trying to display a toast element when an SMS is received. This toast should contain a layout which has an image (SMS Icon) and 2 textviews (sender, message)

If I call the following method from an activity, it works as expected...

public void showToast(Context context, String name, String message) {
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.toast_sms,
                                   (ViewGroup) findViewById(R.id.toast_sms_root));

    TextView text = (TextView) layout.findViewById(R.id.toastsms_text);
    text.setText(message);

    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    toast.show();
}

However, if I try to call the same code in the same way from my SMSReceiver, I get:

The method getLayoutInflater() is undefined for the type SmsReceiver
The method findViewById(int) is undefined for the type SmsReceiver
The method getApplicationContext() is undefined for the type SmsReceiver

Can someone please advise how I can do tihs from an intent. I assume the issue is somehow related to cross-threading however, I'm unsure how to proceed. I've seen a couple of examples online but they seem to either use deprecated code or only display simple text

Can someone please point me in the correct direction

Many thanks

您可以使用 LayoutInflater.from(context) 来获取您的 LayoutInflater。像这样：

LayoutInflater mInflater = LayoutInflater.from(context);
View myView = mInflater.inflate(R.layout.customToast, null);
TextView sender = (TextView) myView.findViewById(R.id.sender);
TextView message = (TextView) myView.findViewById(R.id.message);

You can use LayoutInflater.from(context) to get your LayoutInflater. Like this:

LayoutInflater mInflater = LayoutInflater.from(context);
View myView = mInflater.inflate(R.layout.customToast, null);
TextView sender = (TextView) myView.findViewById(R.id.sender);
TextView message = (TextView) myView.findViewById(R.id.message);
