Unity 获取手机键盘弹出高度

目的

在手机上进行聊天时，键盘弹起会盖住聊天窗口，所以需要键盘弹起的时候，将界面也进行上移。

解决

安卓

publicint GetKeyboardHeight() { using (var unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) { var unityPlayer = unityClass.GetStatic<AndroidJavaObject>("currentActivity").Get<AndroidJavaObject>("mUnityPlayer"); var view = unityPlayer.Call<AndroidJavaObject>("getView"); var dialog = unityPlayer.Get<AndroidJavaObject>("b"); if (view == null || dialog == null) return 0; var decorHeight = 0; if (true)//includeInput { var decorView = dialog.Call<AndroidJavaObject>("getWindow").Call<AndroidJavaObject>("getDecorView"); if (decorView != null) decorHeight = decorView.Call<int>("getHeight"); } using (var rect = new AndroidJavaObject("android.graphics.Rect")) { view.Call("getWindowVisibleDisplayFrame", rect); return Display.main.systemHeight - rect.Call<int>("height") + decorHeight; } } }

苹果

public int GetKeyboardHeight() { return (int)TouchScreenKeyboard.area.height * Display.main.systemHeight / Screen.height; }

调用

float k = gameObject.GetComponentInParent<CanvasScaler>().GetComponent<RectTransform>().sizeDelta.y; float keyboardHeight = SdkManager.Instance.GetKeyboardHeight(); float keyboardHeightUi = keyboardHeight * k / Display.main.systemHeight; m_Rt.anchoredPosition = Vector3.up * keyboardHeightUi;
