如何在Android中检测软键盘 [英] How to detect Soft Keypad in Android

问题描述

美好的一天！

如何检测android中的软键盘是否已激活.

我特地尝试使用这种代码，并伤心地说，它仅检测了android的软键盘的失活.

Good day!

How can I detect if soft keypad in android has been activated.

I''ve tried using this kind of code and sad to say, it detects only for deactivation of soft keypad in android.

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
        if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard but it does not work.
            ... do something here (what i just did was to display a string "ACTIVATED")
        }
        else     //it will work
        {
          ... do something here (what i just did was to display a string "DEACTIVATED")
        }
     }
});

请帮助我解决这个问题.
