AlertDialog在代码中应用

private void showPayFailedDialog(String message) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.dialog_custom);
        View customView = getLayoutInflater().inflate(R.layout.dialog_common, null);
        builder.setView(customView);
        AlertDialog mDialog = builder.create();
        TextView titleTv = customView.findViewById(R.id.titleTv);
        TextView confirmBtn = customView.findViewById(R.id.confirmBtn);
        TextView cancelBtn = customView.findViewById(R.id.cancelBtn);
        titleTv.setText(message);
        if (message.contains("密码")) {
            confirmBtn.setText("忘记支付密码");
        } else {
            confirmBtn.setText("取消");
        }

        cancelBtn.setText("重试");
        //点击事件 用了Java8 lambda表达式
        confirmBtn.setOnClickListener(view -> {
            mDialog.dismiss();
            if (message.contains("密码")) {
                startActivity(new Intent(this, PaySettingsActivity.class));
            }
        });
        //同上
        cancelBtn.setOnClickListener(view -> {
            mDialog.dismiss();
            showPayDialog();
        });
        mDialog.show();
    }
