onClick

Answer 1

如果要在按钮单击时将多个EditText添加到布局中，可以尝试：

$carriers = [];
foreach ($shippingMatrix as $matrix) {
    if ($shippingMethod === $matrix['shippingMethod'] && $country === $matrix['country']) {
        if ($postCode === $matrix['isPostCodeExcluded']) {
            $carriers = [
                $matrix['carrier'],
                $matrix['carrierService'],
            ];
        }
    }

    if ($shippingMethod === $matrix['shippingMethod'] && $country !== $matrix['country'] && !$country) {
        $carriers = [
            $matrix['carrier'],
            $matrix['carrierService'],
        ];
    }
}

在进行修复之前，还有一个非常简单的解决方案。

单击按钮（CalculateButton）时，您需要编辑文本的方式，因此在xml中创建一个编辑文本视图，在屏幕中需要它的位置，并将可见性设置为Gone。

单击CalculateButton时，只显示EditText。

例如：

EditText newEditText;
//Declare this as public variable, because when we use this inside any override methods, the override methods will not let the private variable changes the state until you changes it to final.
newEditText =(EditText) findViewById(R.id.newEditText);

CalculateButton.setOnClickListener(
    new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            EditText NoOfInputsEditText=(EditText)findViewById(R.id.NoOfInputs);
            int size = Integer.parseInt(NoOfInputsEditText.getText().toString()); // total number of TextViews to add
            newEditText.setVisibility(View.VISIBLE);
        }
    }
);
