这段代码工作得很好

根视图使用这个类:

public class KeyboardConstraintLayout extends ConstraintLayout {

private KeyboardListener keyboardListener;
private EditText targetEditText;
private int minKeyboardHeight;
private boolean isShow;

public KeyboardConstraintLayout(Context context) {
    super(context);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height);
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height);
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (!isInEditMode()) {
        Activity activity = (Activity) getContext();
        @SuppressLint("DrawAllocation")
        Rect rect = new Rect();
        getWindowVisibleDisplayFrame(rect);

        int statusBarHeight = rect.top;
        int keyboardHeight = activity.getWindowManager().getDefaultDisplay().getHeight() - (rect.bottom - rect.top) - statusBarHeight;

        if (keyboardListener != null && targetEditText != null && targetEditText.isFocused()) {
            if (keyboardHeight > minKeyboardHeight) {
                if (!isShow) {
                    isShow = true;
                    keyboardListener.onKeyboardVisibility(true);
                }
            }else {
                if (isShow) {
                    isShow = false;
                    keyboardListener.onKeyboardVisibility(false);
                }
            }
        }
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

public boolean isShowKeyboard() {
    return isShow;
}

public void setKeyboardListener(EditText targetEditText, KeyboardListener keyboardListener) {
    this.targetEditText = targetEditText;
    this.keyboardListener = keyboardListener;
}

public interface KeyboardListener {
    void onKeyboardVisibility (boolean isVisible);
}

}

在activity或fragment中设置键盘监听器:

    rootLayout.setKeyboardListener(targetEditText, new KeyboardConstraintLayout.KeyboardListener() {
    @Override
    public void onKeyboardVisibility(boolean isVisible) {

    }
});

也许这对你有帮助:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

医生说… https://developer.android.com/reference/androidx/core/view/WindowInsetsCompat

检查放行说明.. https://developer.android.com/jetpack/androidx/releases/core#1.5.0-alpha02

要获得当前键盘可见性，可以使用getRootWindowInsets，然后调用isVisible()函数，传入IME类型。

val windowinsetscompat = ViewCompat.getRootWindowInsets(view)
val imeVisible = windowinsetscompat.isVisible(Type.ime())

也有监听OnApplyWindowInsetsListener的变化

ViewCompat.setOnApplyWindowInsetsListener(view) { v, insets ->
    val imeVisible = insets.isVisible(Type.ime())
}

我知道这是一篇老文章，但我认为这是我所知道的最简单的方法，我的测试设备是Nexus 5。我还没有在其他设备上尝试过。希望其他人会分享他们的方法，如果他们发现我的代码不好:)

public static boolean isKeyboardShown(Context context, View view) {
        if (context == null || view == null) {
            return false;
        }
        InputMethodManager imm = (InputMethodManager) context
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        return imm.hideSoftInputFromWindow(view.getWindowToken(), 0); 
}

imm。hideSoftInputFromWindow返回布尔值。

谢谢,

不要编写任何硬代码。最好的方法是，你必须调整你的视图，而Get Focus on EditText与键盘显示。 您可以使用下面的代码将活动上的resize属性添加到清单文件中。

android: windowSoftInputMode = adjustResize”

我使用了与鲁班的答案略有不同的答案，事实证明在某些情况下更有帮助，特别是在使用高分辨率设备时。

final View activityRootView = findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
        new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightView = activityRootView.getHeight();
                int widthView = activityRootView.getWidth();
                if (1.0 * widthView / heightView > 3) {
                    //Make changes for Keyboard not visible
                } else {
                    //Make changes for keyboard visible
                }
            }
        });
