¿No podría hacerse solo con un botón positivo?
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();
Podrías usar esto:
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();
Otro enfoque
Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show();
Prima
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();
Ahora depende de usted usar uno, dos o tres botones.
Esto es lo más cerca que podría estar de la línea que debería ser si la API de Android fuera inteligente:
new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();
Para reutilizar el código, puede hacerlo en un método como este
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
}
// Otros problemas de reutilización de código, como el uso de interfaces para proporcionar comentarios, también serán excelentes.
Kotlin?
val dialogBuilder = AlertDialog.Builder(this.context)
dialogBuilder.setTitle("Alert")
.setMessage(message)
.setPositiveButton("OK", null)
.create()
.show()
Es muy simple
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();

En Mono para Android puedes hacer esto:
var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();
