How to show a pop up in Android Studio to confirm an order?
提问by AldoT
I want to show a pop up or a prompt when a user makes an order in my app (pressing a button) for them to confirm the amount of the product and the price. How can I do that?? Some people say with a AlerDialog but I am not sure. This alert would have two buttons: "Confirm" and "Cancel".
当用户在我的应用程序中下订单（按下按钮）时，我想显示一个弹出窗口或提示，以便他们确认产品的数量和价格。我怎样才能做到这一点？？有些人用 AlerDialog 说，但我不确定。此警报将有两个按钮：“确认”和“取消”。
Thanks in advace.
预先感谢。

AlertDialog suits your needs, and simple to implement.
AlertDialog 适合您的需求，并且易于实施。
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setCancelable(true);
builder.setTitle("Title");
builder.setMessage("Message");
builder.setPositiveButton("Confirm",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog dialog = builder.create();
dialog.show();

What exactly are you not sure about? It's as simple as 1, 2, 3
你到底不确定什么？就像 1、2、3 一样简单
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.confirm_dialog_message)
.setTitle(R.string.confirm_dialog_title)
.setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// CONFIRM
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// CANCEL
}
});
// Create the AlertDialog object and return it
return builder.create();

You could use the alert builder for this:
您可以为此使用警报构建器：
new AlertDialog.Builder(context)
.setTitle("Confirm Order")
.setMessage("Are you sure?")
.setPositiveButton(@"Confirm", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(@"Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
