我們想實(shí)現(xiàn)安卓鍵盤彈起和隱藏的監(jiān)聽事件，可以使用下面這個(gè)方法。

自己新建一個(gè)java文件，內(nèi)容如下:

public class SoftKeyBoardListener {private View rootView;//activity的根視圖int rootViewVisibleHeight;//紀(jì)錄根視圖的顯示高度private OnSoftKeyBoardChangeListener onSoftKeyBoardChangeListener;public SoftKeyBoardListener(Activity activity) {//獲取activity的根視圖rootView = activity.getWindow().getDecorView();//監(jiān)聽視圖樹中全局布局發(fā)生改變或者視圖樹中的某個(gè)視圖的可視狀態(tài)發(fā)生改變rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {@Overridepublic void onGlobalLayout() {//獲取當(dāng)前根視圖在屏幕上顯示的大小Rect r = new Rect();//獲取rootView在窗體的可視區(qū)域rootView.getWindowVisibleDisplayFrame(r);int visibleHeight = r.height();if (rootViewVisibleHeight == 0) {rootViewVisibleHeight = visibleHeight;return;}//根視圖顯示高度沒有變化，可以看作軟鍵盤顯示／隱藏狀態(tài)沒有改變if (rootViewVisibleHeight == visibleHeight) {return;}//根視圖顯示高度變小超過(guò)200，可以看作軟鍵盤顯示了if (rootViewVisibleHeight - visibleHeight > 200) {if (onSoftKeyBoardChangeListener != null) {onSoftKeyBoardChangeListener.keyBoardShow(rootViewVisibleHeight - visibleHeight);}rootViewVisibleHeight = visibleHeight;return;}//根視圖顯示高度變大超過(guò)200，可以看作軟鍵盤隱藏了if (visibleHeight - rootViewVisibleHeight > 200) {if (onSoftKeyBoardChangeListener != null) {onSoftKeyBoardChangeListener.keyBoardHide(visibleHeight - rootViewVisibleHeight);}rootViewVisibleHeight = visibleHeight;return;}}});}private void setOnSoftKeyBoardChangeListener(OnSoftKeyBoardChangeListener onSoftKeyBoardChangeListener) {this.onSoftKeyBoardChangeListener = onSoftKeyBoardChangeListener;}public interface OnSoftKeyBoardChangeListener {void keyBoardShow(int height);void keyBoardHide(int height);}public static void setListener(Activity activity, OnSoftKeyBoardChangeListener onSoftKeyBoardChangeListener) {SoftKeyBoardListener softKeyBoardListener = new SoftKeyBoardListener(activity);softKeyBoardListener.setOnSoftKeyBoardChangeListener(onSoftKeyBoardChangeListener);} }

在activity中調(diào)用

//自動(dòng)監(jiān)聽鍵盤事件 SoftKeyBoardListener.setListener(this, new SoftKeyBoardListener.OnSoftKeyBoardChangeListener() {@Overridepublic void keyBoardShow(int height) {Toast.makeText(PostActivity.this, "鍵盤顯示 高度" + height, Toast.LENGTH_SHORT).show();}@Overridepublic void keyBoardHide(int height) {Toast.makeText(PostActivity.this, "鍵盤隱藏 高度" + height, Toast.LENGTH_SHORT).show();} });
