Is possible to customize positive and negative buttons in AlertDialog?

问题

Is possible to customize positive and negative buttons in AlertDialog ? I need to replace default look of positive and negative with custom.

.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {...
.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {...

Can somebody tell me how to do that ?

回答1:

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);
    }
}
}

if you want to change them, I will suggest using activity with your required layout and add them= Dialog in your activity, in Manifest file

回答3:

if you want to customize you can use dialog instead of alert dialog here is the sample code

    final Dialog dialog = new Dialog(ThisweekActivity.this, android.R.style.Theme_Translucent_NoTitleBar);
    View view = LayoutInflater.from(ThisweekActivity.this).inflate(R.layout.issue_cover_prompt_layout, null);
    view.findViewById(R.id.close_btn).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });
    ImageView img = (ImageView) view.findViewById(R.id.issue_cover_img);
    img.setImageBitmap(issue.getCoverImage());

    dialog.setContentView(view);
    dialog.show();

you can set set the layout in dialog and add click listner on it

Yuo can set every view in dialog box. You can set view with two buttons and dont set positive & negative buttons.

example:

AlertDialog.Builder builder = 
            new AlertDialog.Builder(this);

View dialogView = LayoutInflater.from(this)
            .inflate(R.layout.my_layout, null);

builder.setView(dialogView);
