软件键盘的android可视性

我想检查软件键盘是否可见。我读过这个

但是

activityRootView.getRootView（）.getHeight（）

和

activityRootView.getHeight（）

始终返回相同的值，不关心键盘是否可见。你知道为什么吗？因为这个解决方案似乎对其他人有效

此代码可能会有所帮助-

public void dismissKeyboard(){
    InputMethodManager imm =(InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(mSearchBox.getWindowToken(), 0);
    mKeyboardStatus = false;
}

public void showKeyboard(){
    InputMethodManager imm =(InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
    mKeyboardStatus = true;
}

private boolean isKeyboardActive(){
    return mKeyboardStatus;
}

mKeyboardStatus的默认布尔值将初始化为false

然后按如下方式检查值，必要时执行操作：

mSearchBox.requestFocus();
if(!isKeyboardActive()){
    showKeyboard();
}else{
    dismissKeyboard();
}

找到答案的最简单方法-

contentView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
 public void onGlobalLayout() {

Rect r = new Rect();
contentView.getWindowVisibleDisplayFrame(r);
int screenHeight = contentView.getRootView().getHeight();

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

Log.d(TAG, "keypadHeight = " + keypadHeight);

if (keypadHeight > screenHeight * 0.20) { // 0.20 ratio is perhaps enough to determine keypad height.
    // keyboard is opened
}
else {
    // keyboard is closed
}
}
});
