जवाबों:
केवल एक सकारात्मक बटन का उपयोग करके ऐसा नहीं किया जा सकता है?
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();
आप इसका उपयोग कर सकते हैं:
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();
एक और दृष्टिकोण
Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show();
बक्शीश
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();
अब यह आपके ऊपर है कि आप एक, दो या तीन बटन का उपयोग करें।
यह करीब एक लाइनर के लिए मुझे मिल सकता है यह होना चाहिए अगर Android एपीआई किसी भी स्मार्ट था:
new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();
कोड पुन: उपयोग के लिए, आप इसे इस तरह से बना सकते हैं
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
}
// प्रतिक्रिया प्रदान करने के लिए इंटरफेस का उपयोग करने जैसे अन्य कोड का उपयोग भी उत्कृष्ट होगा।
Kotlin?
val dialogBuilder = AlertDialog.Builder(this.context)
dialogBuilder.setTitle("Alert")
.setMessage(message)
.setPositiveButton("OK", null)
.create()
.show()
यह बहुत सरल है
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();

Android के लिए मोनो में आप ऐसा कर सकते हैं:
var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();
