推荐答案
public class ComentarDialog extends DialogFragment{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage("Mensaje de alerta")
.setTitle("Comentar")
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
})
.setNegativeButton("CANCELAR", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
return builder.create();
}
@Override
public void onStart() {
super.onStart();
//Personalizamos
Resources res = getResources();
//Buttons
Button positive_button = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_POSITIVE);
positive_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));
Button negative_button = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_NEGATIVE);
negative_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));
int color = Color.parseColor("#304f5a");
//Title
int titleId = res.getIdentifier("alertTitle", "id", "android");
View title = getDialog().findViewById(titleId);
if (title != null) {
((TextView) title).setTextColor(color);
}
//Title divider
int titleDividerId = res.getIdentifier("titleDivider", "id", "android");
View titleDivider = getDialog().findViewById(titleDividerId);
if (titleDivider != null) {
titleDivider.setBackgroundColor(color);
}
