当页面使用nativescript在android应用中加载页面时，如何显示键盘? [英] How to show keyboard when page loads in android app with nativescript?

问题描述

我的android应用程序的第一页有一个输入字段.所以我想要的是当此页面加载时，我想自动显示键盘而无需在输入字段上进行点击.

The first page of my android application has one input field. So what I want is when this page loads I want to show keyboard automatically without doing tap on the input field.

推荐答案

pkanev的评论在ios上为true；也就是说，只要专注于文本字段，ios就会打开键盘.

pkanev's comment is true on ios; ie, just focus on the text field and ios will open up the keyboard.

但是在Android上，您需要做一些额外的工作-

But on Android you need to do some extra work --

var utils = require("tns-core-modules/utils/utils");

var myTextfield = page.getViewById("myTextFieldId");

if (myTextfield.ios) {
    console.log("myTextfield.ios");

    // on ios this will open the keyboard but not on android
    myTextfield.focus();
}

if (myTextfield.android) {
    console.log("myTextfield.android");

    setTimeout(function() {

        // places the cursor here but doesn't open the keyboard
        myTextfield.android.requestFocus();

        var imm = utils.ad.getInputMethodManager();

        imm.showSoftInput(myTextfield.android, 0);

    }, 300);
}

请注意使用setTimeout，这也是您在本机Android中也需要做的事情.

Notice the use of setTimeout which is what you would need to do in native Android too.
