libgdx 如何检测键盘的存在

How do libgdx detect keyboard presence(libgdx 如何检测键盘的存在)

问题描述

在文本域中书写时，我需要将文本域向上移动，以便在键盘弹出时让文本域可见.

When writing in the Textfield, I need my textfield to move upwards in order to let the textfield be visible when the keyboard pops up.

libgdx 是否有某种方法可以在键盘可见时返回 true，在键盘关闭时返回 false?

Does libgdx have some kind of method which returns true if the keyboard is visible and false when it is down?

推荐答案

以下代码将检测您何时按下文本字段，阻止其显示键盘，然后打开一个随键盘上下移动的本机对话框.它将从本机对话框中获取输入，最后将其放回您的文本字段中:

The following code will detect when you press a textfield, prevent it from showing the keyboard and then open a native dialog that moves up and down with the keyboard. It will take the input from the native dialog and finally put it back in your textField:

    textField.setOnscreenKeyboard(new TextField.OnscreenKeyboard() {
        @Override
        public void show(boolean visible) {
            //Gdx.input.setOnscreenKeyboardVisible(true);
            Gdx.input.getTextInput(new Input.TextInputListener() {
                @Override
                public void input(String text) {
                    textField.setText(text);
                }

                @Override
                public void canceled() {
                    System.out.println("Cancelled.");
                }
            }, "Title", "Default text...");
        }
    });
