Size of button in alertdialog

how can i change the size of button in alertdailog in code without using xml ? I'm not using view ..

Thank you The code : alertbox3.setNeutralButton("Cancel",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) {开发者_C百科 } });

you may try this code:

 AlertDialog.Builder adb = new AlertDialog.Builder(this);
 Dialog d = adb.setView(new View(this)).create();
// (That new View is just there to have something inside the dialog that can grow big enough to cover the whole screen.)

WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(d.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.FILL_PARENT;
lp.height = WindowManager.LayoutParams.FILL_PARENT;
d.show();
d.getWindow().setAttributes(lp);

and http://developer.android.com/reference/android/widget/Button.html

look at this link aslo . Link1 and LInk2

you should use a customView for your case to change the button layout. see the following link on how to make your own view for alertDialog.

How to implement a custom AlertDialog View

Try this : https://stackoverflow.com/a/15910202/305135

final AlertDialog alert = builder.create();
alert.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        Button btnPositive = alert.getButton(Dialog.BUTTON_POSITIVE);
        btnPositive.setTextSize(TEXT_SIZE);

        Button btnNegative = alert.getButton(Dialog.BUTTON_NEGATIVE);
        btnNegative.setTextSize(TEXT_SIZE);
    }
});

return alert;

Why do you want to? The system will construct a standard dialog layout on your behalf that follows conventions that the user expects and is familiar with. In general you should not go out of your way to circumvent this.
