如何以编程方式删除AlertDialog [英] How to remove AlertDialog programmatically

问题描述

在android应用程序中，我向用户显示一个AlertDialog，没有按钮，只有一条消息.如何以编程方式销毁AlertDialog，以使其不再可见?我尝试使用cancel()和dismiss()，但是它们不起作用，视图仍然存在.

In an android application, I'm showing to the user an AlertDialog with no buttons, just a message. How can I destroy the AlertDialog programmatically so that it's not visible anymore? I tried with cancel() and dismiss() but they are not working, the view remains there.

AlertDialog.Builder test = new AlertDialog.Builder(context);
test.setTitle("title");
test.setCancelable(true);
test.setMessage("message...");
test.create().show();

然后我尝试了

test.show().cancel()和

test.show().dismiss()

但不起作用.

推荐答案

您应该引用AlertDialog本身，而不是生成器.

You should refer to the AlertDialog itself, not the builder.

AlertDialog.Builder test = new AlertDialog.Builder(context);
test.setTitle("title");
test.setCancelable(true);
test.setMessage("message...");
ALertDialog testDialog = test.create();
testDialog.show();  // to show
testDialog.dismiss();  // to dismiss
