试试这段代码，它真的工作，如果keyboardshow是显示的，那么这个函数返回真值....

private final String TAG = "TextEditor";
private TextView mTextEditor;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_editor);
    mTextEditor = (TextView) findViewById(R.id.text_editor);
    mTextEditor.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            isKeyboardShown(mTextEditor.getRootView());
        }
    });
}

private boolean isKeyboardShown(View rootView) {
    /* 128dp = 32dp * 4, minimum button height 32dp and generic 4 rows soft keyboard */
    final int SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD = 128;

    Rect r = new Rect();
    rootView.getWindowVisibleDisplayFrame(r);
    DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
    /* heightDiff = rootView height - status bar height (r.top) - visible frame height (r.bottom - r.top) */
    int heightDiff = rootView.getBottom() - r.bottom;
    /* Threshold size: dp to pixels, multiply with display density */
    boolean isKeyboardShown = heightDiff > SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD * dm.density;

    Log.d(TAG, "isKeyboardShown ? " + isKeyboardShown + ", heightDiff:" + heightDiff + ", density:" + dm.density
            + "root view height:" + rootView.getHeight() + ", rect:" + r);

    return isKeyboardShown;
}

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”。

这应该工作，如果你需要检查键盘状态:

fun Activity.isKeyboardOpened(): Boolean {
    val r = Rect()

    val activityRoot = getActivityRoot()
    val visibleThreshold = dip(UiUtils.KEYBOARD_VISIBLE_THRESHOLD_DP)

    activityRoot.getWindowVisibleDisplayFrame(r)

    val heightDiff = activityRoot.rootView.height - r.height()

    return heightDiff > visibleThreshold;
}

fun Activity.getActivityRoot(): View {
    return (findViewById<ViewGroup>(android.R.id.content)).getChildAt(0);
}

UiUtils的地方。KEYBOARD_VISIBLE_THRESHOLD_DP = 100, dip()是一个anko函数，转换dpToPx:

fun dip(value: Int): Int {
    return (value * Resources.getSystem().displayMetrics.density).toInt()
}

试试这个:

InputMethodManager imm = (InputMethodManager) getActivity()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        writeToLog("Software Keyboard was shown");
    } else {
        writeToLog("Software Keyboard was not shown");
    }

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。

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();
        }
    }
}
