উত্তর:
কেবলমাত্র পজিটিভ বাটন ব্যবহার করে এটি করা যায় না?
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();
আপনি এটি ব্যবহার করতে পারেন:
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();
অন্য পদ্ধতির
Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show();
বোনাস
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();
এখন এক, দুটি বা তিনটি বোতাম ব্যবহার করা আপনার উপর নির্ভর করে ..
অ্যান্ড্রয়েড এপিআই যদি কোনও স্মার্ট হয় তবে এটির একটি লাইনারের কাছাকাছি যেতে পারলে এটি হওয়া উচিত:
new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();
কোড পুনঃব্যবহারের জন্য, আপনি এটি এই জাতীয় পদ্ধতিতে তৈরি করতে পারেন
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
}
// অন্যান্য কোড পুনরায় ব্যবহার সংক্রান্ত মতামত যেমন প্রতিক্রিয়া সরবরাহের জন্য ইন্টারফেস ব্যবহার করাও দুর্দান্ত excellent
Kotlin?
val dialogBuilder = AlertDialog.Builder(this.context)
dialogBuilder.setTitle("Alert")
.setMessage(message)
.setPositiveButton("OK", null)
.create()
.show()
এটা খুবই সাধারণ
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();

অ্যান্ড্রয়েডের জন্য মনোতে আপনি এটি করতে পারেন:
var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();
