"確定", "取消", true, new DialogUtil.AlertDialogBtnClickListener() {

@Override

public void clickPositive() {

//positive

}

@Override

public void clickNegative() {

//negative

}

});

工具類主要代碼

public class DialogUtil {

private static AlertDialog dialog;

/**

* @param activity Context

* @param iconRes 提示圖標(biāo)

* @param title 提示標(biāo)題

* @param msg 提示內(nèi)容

* @param positiveText 確認(rèn)

* @param negativeText 取消

* @param cancelableTouchOut 點擊外部是否隱藏提示框

* @param alertDialogBtnClickListener 點擊監(jiān)聽

*/

public static void showAlertDialog(Activity activity, int iconRes, String title, String msg,

String positiveText, String negativeText, boolean

cancelableTouchOut, final AlertDialogBtnClickListener

alertDialogBtnClickListener) {

View view = LayoutInflater.from(activity).inflate(R.layout.custom_dialog_layout, null);

ImageView mIcon = view.findViewById(R.id.icon);

TextView mTitle = view.findViewById(R.id.title);

TextView mMessage = view.findViewById(R.id.message);

mTitle.setText(title);

mMessage.setText(msg);

positiveButton.setText(positiveText);

negativeButton.setText(negativeText);

positiveButton.setOnClickListener(v -> {

alertDialogBtnClickListener.clickPositive();

dialog.dismiss();

});

negativeButton.setOnClickListener(v -> {

alertDialogBtnClickListener.clickNegative();

dialog.dismiss();

});

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

builder.setView(view);

builder.setCancelable(true); //返回鍵dismiss

//創(chuàng)建對話框

dialog = builder.create();

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);//去掉圓角背景背后的棱角

dialog.setCanceledOnTouchOutside(cancelableTouchOut); //失去焦點dismiss

dialog.show();

}
