TextField文本字段不会在QML上返回值|QT 5.12 [英] TextField text field doesn't return value on QML | QT 5.12

问题描述

我需要帮助.这是我的代码:

i need an help. So this is my code:

TextField {
    id: passwordIDText
    placeholderText: "Insert text..."
    color: "Black"
    font.bold: true
    font.pixelSize: 21
    anchors.top: parent.top
    anchors.topMargin: parent.height / 10
    anchors.horizontalCenter: parent.horizontalCenter
    text: "aaa"
}

我使用的是Android 8(P20)，QT 12.4，Android NDK 20和Android SDK 28.因此，当我单击android屏幕上的按钮(我正在使用20进行测试)时，在调试中，为了获取passwordIDText.text，该字段为空，为什么?但是，如果我将文本设置为:"aaa"硬编码，则会得到passwordIDText.text ="aaa".

I use Android 8 (P20), QT 12.4, Android NDK 20 and Android SDK 28. So when i click the button on the android screen (i'm using 20 to testing), in debug, for get the passwordIDText.text, the field is empty, why ?? But if i set text: "aaa" hard coded, i get passwordIDText.text = "aaa".

问题外观TextField无法获得用户插入的值.我在屏幕上的TextField上插入了123456，然后单击Button:

The problem look TextField don't get the value inserted by the user. I've inserted 123456 on TextField on screen and click on Button:

MouseArea {
    anchors.fill: parent
    onClicked: {
        var test = passwordIDText.text;
        //passwordIDText.text is empty wtf !??

    }
}

那么有人有同样的问题吗?在较旧的Android版本上，TextField可以正常工作.

So someone have the same problem ? On the older Android version TextField works correctly.

推荐答案

我认为这可能与

I believe it might be an issue similar to this question, related to predictive text not being committed at the time you need to access it.

尝试使用 passwordIDText.displayText 而不是 passwordIDText.text .

或者，您可以拒绝预想输入法:

Alternatively you can turn down predictive text input:
