Android AlertDialog 单按钮

Question

我想要一个 AlertDialog 构建器，它只有一个按钮，上面写着 OK 或 Done 或其他东西，而不是默认的是和否。 这可以用标准的 AlertDialog 来完成，还是我必须使用其他东西？

Answer 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();

Answer 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();

Answer 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();

现在您可以使用一个、两个或三个按钮..

Answer 4

如果 Android API 很聪明的话，这应该是我最接近的一种方式：

new AlertDialog.Builder(this)
    .setMessage(msg)
    .setPositiveButton("OK", null)
    .show();

Answer 5

为了代码重用，你可以用这样的方法来做

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，如使用接口提供反馈也将非常好。

  val dialogBuilder = AlertDialog.Builder(this.context)
  dialogBuilder.setTitle("Alert")
               .setMessage(message)
               .setPositiveButton("OK", null)
               .create()
               .show()

非常简单

new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",            
                        new DialogInterface.OnClickListener()                      
                        {   public void onClick(DialogInterface di,int id)     
                            {

Answer 10

在 Android 的 Mono 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();
