在Android中，你可以通过ADB shell进行检测。我写下并使用了这个方法:

{
        JSch jsch = new JSch();
        try {
            Session session = jsch.getSession("<userName>", "<IP>", 22);
            session.setPassword("<Password>");
            Properties config = new Properties();
            config.put("StrictHostKeyChecking", "no");
            session.setConfig(config);
            session.connect();

            ChannelExec channel = (ChannelExec)session.openChannel("exec");
            BufferedReader in = new BufferedReader(new    
            InputStreamReader(channel.getInputStream()));
            channel.setCommand("C:/Android/android-sdk/platform-tools/adb shell dumpsys window 
            InputMethod | findstr \"mHasSurface\"");
            channel.connect();

            String msg = null;
            String msg2 = " mHasSurface=true";

            while ((msg = in.readLine()) != null) {
                Boolean isContain = msg.contains(msg2);
                log.info(isContain);
                if (isContain){
                    log.info("Hiding keyboard...");
                    driver.hideKeyboard();
                }
                else {
                    log.info("No need to hide keyboard.");
                }
            }

            channel.disconnect();
            session.disconnect();

        } catch (JSchException | IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

final View activityRootView = findViewById(R.id.rootlayout);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            Rect r = new Rect();
            activityRootView.getWindowVisibleDisplayFrame(r);

            int screenHeight = activityRootView.getRootView().getHeight();
            Log.e("screenHeight", String.valueOf(screenHeight));
            int heightDiff = screenHeight - (r.bottom - r.top);
            Log.e("heightDiff", String.valueOf(heightDiff));
            boolean visible = heightDiff > screenHeight / 3;
            Log.e("visible", String.valueOf(visible));
            if (visible) {
                Toast.makeText(LabRegister.this, "I am here 1", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(LabRegister.this, "I am here 2", Toast.LENGTH_SHORT).show();
            }
        }
});

可以使用showSoftInput()和hideSoftInput()的回调结果来检查键盘的状态。完整的细节和示例代码在

https://rogerkeays.com/how-to-check-if-the-software-keyboard-is-shown-in-android

你可以参考这个答案- https://stackoverflow.com/a/24105062/3629912

每次都很管用。

adb shell dumpsys window InputMethod | grep "mHasSurface"

如果软件键盘可见，它将返回true。

我把答案转换为kotlin，希望这对kotlin用户有帮助。

private fun checkKeyboardVisibility() {
    var isKeyboardShowing = false

    binding.coordinator.viewTreeObserver.addOnGlobalLayoutListener {
        val r = Rect()
        binding.coordinator.getWindowVisibleDisplayFrame(r)
        val screenHeight = binding.coordinator.rootView.height

        // r.bottom is the position above soft keypad or device button.
        // if keypad is shown, the r.bottom is smaller than that before.
        val keypadHeight = screenHeight - r.bottom


        if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
            // keyboard is opened
            if (!isKeyboardShowing) {
                isKeyboardShowing = true

            }
        } else {
            // keyboard is closed
            if (isKeyboardShowing) {
                isKeyboardShowing = false

            }
        }
    }
}

我写了样本。

这个存储库可以帮助检测键盘状态，而无需假设“键盘应该超过屏幕的X部分”。
