Android中监听软键盘显示状态实现代码

/**监听软键盘状态 * @param activity * @param listener */public static void addOnSoftKeyBoardVisibleListener（Activity activity, final OnSoftKeyBoardVisibleListener listener） {final View decorView = activity.getWindow（）.getDecorView（）;decorView.getViewTreeObserver（）.addOnGlobalLayoutListener（new ViewTreeObserver.OnGlobalLayoutListener（） {@Overridepublic void onGlobalLayout（） {Rect rect = new Rect（）;decorView.getWindowVisibleDisplayFrame（rect）;int displayHight = rect.bottom - rect.top;int hight = decorView.getHeight（）;boolean visible = （double） displayHight / hight < 0.8; Log.d（TAG, "DecorView display hight = " + displayHight）;Log.d（TAG, "DecorView hight = " + hight）;Log.d（TAG, "softkeyboard visible = " + visible）; if（visible ！= sLastVisiable）{listener.onSoftKeyBoardVisible（visible）;}sLastVisiable = visible;}}）;}
