Android SDK中覆盖AlertDialog事件 [英] Android SDK override AlertDialog events
本文介绍了Android SDK中覆盖AlertDialog事件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我实例化一个警告对话框,如下所示:
AlertDialog myAlert =新AlertDialog.Builder(myContext).create();
有没有办法来覆盖此对话框的的onkeydown
事件?
解决方案
AlertDialog.Builder打造=新AlertDialog.Builder(本);
build.setMessage(这是一个消息,耶。)
.setPositiveButton(Awesomesauce。新OnClickListener()
{
公共无效的onClick(DialogInterface对话框,INT ID)
{
//这里的东西
dialog.dismiss(); //关闭窗口
}
};
AlertDialog myAlert = build.create();
myAlert.show();
您还可以添加 .setNegativeButton()
或 .setNeutralButton()
来改变中性/负按钮了。
Android的SDK文档,因为这是这里
I am instantiating an alert dialog like so:
AlertDialog myAlert = new AlertDialog.Builder(myContext).create();
Is there a way to override the OnKeyDown
event for this dialog?
解决方案
AlertDialog.Builder build=new AlertDialog.Builder(this);
build.setMessage("This is a message, dawg.")
.setPositiveButton("Awesomesauce.", new OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
//stuff here
dialog.dismiss(); //closes the window
}
};
AlertDialog myAlert=build.create();
myAlert.show();
You can also add a .setNegativeButton()
or .setNeutralButton()
to change the neutral/negative buttons, too.
The Android SDK doc for it is here.
