align AlertDialog buttons to center
This worked for me :
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.AppCompatAlertDialogStyle);
builder.setCancelable(true);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
final AlertDialog dialog = builder.create();
dialog.show(); //show() should be called before dialog.getButton().
final Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
LinearLayout.LayoutParams positiveButtonLL = (LinearLayout.LayoutParams) positiveButton.getLayoutParams();
positiveButtonLL.gravity = Gravity.CENTER;
positiveButton.setLayoutParams(positiveButtonLL);
Use crtn's method, but instead of changing the LayoutParam's
gravity, change its width to ViewGroup.LayoutParams.MATCH_PARENT;
If you want to have Positive And Negative Buttons at the same time (Large & Center), you can use something like this:
AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Title");
alertDialog.setMessage("Message");
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.show();
Button btnPositive = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
Button btnNegative = alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE);
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) btnPositive.getLayoutParams();
layoutParams.weight = 10;
btnPositive.setLayoutParams(layoutParams);
btnNegative.setLayoutParams(layoutParams);
