Question

Android排球无法正常运行，我已经使用两种方法来解决此http问题。

清单

android:networkSecurityConfig="@xml/network_security_config"

xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

还有

 android:usesCleartextTraffic="true"

Answer 1

尝试一下：

xml

public void Total (String total){

    Log.d("log2","total: " + total);// it prints 30.00

    Double number_total = Double.parseDouble(total);

    Log.d("log2","number_total: " + total);// it prints 30.0
    losing a decimal place.

    array_Total.add (number_total); //Arraylist<Double
    sum (double) = sum + number_total;
    String strSum = (Double.toString(sum));
    total.setText (strSum);
}
