【中文标题】Android AlertDialog 单按钮【英文标题】：Android AlertDialog Single Button 【发布时间】：2011-08-14 04:23:56 【问题描述】：我想要一个 AlertDialog 构建器，它只有一个按钮，显示 OK 或 Done 或其他内容，而不是默认的 yes 和 no。 可以使用标准的 AlertDialog 来完成，还是我必须使用其他东西？
【问题讨论】：
【参考方案1】：难道不能只使用一个肯定按钮来完成吗？
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Look at this dialog!")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
//do things
);
AlertDialog alert = builder.create();
alert.show();

效果很好，只要您不介意那个右对齐的单个按钮。 :( @ScottBiggs 对话框中的按钮对齐方式由系统决定，可以在设备、版本和语言（RTL 等）之间更改。应用程序不应尝试设置对齐方式，而是设置意图（正面、负面等） 太棒了！谢谢！ 我不希望按钮执行任何操作，它应该只是关闭警报框，创建一个空的 onClick 侦听器是一个好习惯还是应该使用不同的方法。【参考方案2】：你可以用这个：
AlertDialog.Builder builder1 = new AlertDialog.Builder(this);
builder1.setTitle("Title");
builder1.setMessage("my message");
builder1.setCancelable(true);
builder1.setNeutralButton(android.R.string.ok,
new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
dialog.cancel();
);
AlertDialog alert11 = builder1.create();
alert11.show();
【讨论】：
【参考方案3】：另一种方法
Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show();
奖金
AlertDialog.Builder builder = new AlertDialog.Builder(YourActivityName.this);
builder.setMessage("Message dialog with three buttons");
builder.setPositiveButton("YES", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
//do things
);
builder.setNegativeButton("NO", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
//do things
);
builder.setNeutralButton("CANCEL", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
//do things
);
AlertDialog alert = builder.create();
alert.show();
现在由你决定使用一个、两个或三个按钮..
【讨论】：
【参考方案4】：如果 Android API 很聪明的话，我可以更接近这一行：
new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();
【讨论】：
那不会导致一个按钮右对齐吗？ 简单易行。谢谢【参考方案5】：为了代码重用，你可以用这样的方法来实现
public static Dialog getDialog(Context context,String title, String message, DialogType typeButtons )
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title)
.setMessage(message)
.setCancelable(false);
if (typeButtons == DialogType.SINGLE_BUTTON)
builder.setPositiveButton("OK", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int id)
//do things
);
AlertDialog alert = builder.create();
return alert;
public enum DialogType
SINGLE_BUTTON
//其他代码重用问题，例如使用接口提供反馈也将非常好。
【讨论】：
@MarianPaździoch 你为什么这么认为？ 如果我想添加四个按钮怎么办？ 如果它只是一个没有监听器的带有单个按钮的“确认对话框”，这没关系。除此之外，不值得包裹在这样的助手中，因为您需要处理每个按钮的按下。【参考方案6】：科特林？
val dialogBuilder = AlertDialog.Builder(this.context)
dialogBuilder.setTitle("Alert")
.setMessage(message)
.setPositiveButton("OK", null)
.create()
.show()
【讨论】：
【参考方案7】：警报对话框
带有单个按钮的警报对话框。
带有图标的警报对话框。
带有三个按钮的警报对话框。
带有选择选项的警报对话框，单选按钮。
带有多选选项的警报对话框，复选框按钮。

【讨论】：
【参考方案8】：很简单
new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",
new DialogInterface.OnClickListener()
public void onClick(DialogInterface di,int id)
output.setText(input.getText().toString());
)
.create().show();
如果您想阅读完整的程序，请参阅此处： Program to take input from user using dialog and output to screen

【参考方案9】：在 Mono for Android 中，您可以这样做：
var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate ad.Dispose(); );
ad.Show();
