? ? ? 之前博客中,介紹過使用谷歌提供的鍵盤的一些api,可以很好地自定義鍵盤,參考我之前的博客鏈接:android 自定義鍵盤?,這個有一個局限性,只能占滿屏幕,無法做到只能占一部分的需求鍵盤,如下圖我平板中的鍵盤需求:(由于公司保密需要,所以比較恐怖一點,嘿嘿)

? ? ?類似于上方的左下角的一小塊鍵盤,這就不能使用系統自帶的一些鍵盤api,需要自己寫布局,并且對輸入的金額進行位數的限制,以及一些欄位輸入的整數和小數位的控制,整體的實現步驟如下;

1.點擊某個edittext,彈出下方的鍵盤(也就是使用popuwindow的方式),需要監聽edittext獲得焦點以及點擊的事件,還需要隱藏掉系統自帶的鍵盤,如下:

limitEditText = (EditText) fragmentLayout.findViewById(R.id.ordertrade_limit_price);//禁止系統鍵盤彈出MainActionUtilHelper.hideSoftInputMethod(limitEditText, getActivity());digit = allone.verbank.apad.client.util.InstrumentUtil.getDigitByInstrument(instName);limitEditText.setOnFocusChangeListener(new android.view.View.OnFocusChangeListener() {@Overridepublic void onFocusChange(View v, boolean hasFocus) {if (hasFocus) {if (popupMenu != null) {popupMenu.destroyPopupMenu();}popupMenu = PopupMenuFactory.createPopupWindowKeyBoard(getActivity(), limitEditText, order_amount_layout,IPopupMenu.MENU_TYPE_JPY, digit == 2, digit);popupMenu.showPopupMenu();popupMenu.createPupupWindow().setOnDismissListener(new PopupWindow.OnDismissListener() {@Overridepublic void onDismiss() {}});} else {// 此處為失去焦點時的處理內容}}});//監聽彈出數字鍵盤limitEditText.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View vi) {if (popupMenu != null) {popupMenu.destroyPopupMenu();}// 浮出菜單popupMenu = PopupMenuFactory.createPopupWindowKeyBoard(getActivity(), limitEditText, order_amount_layout,IPopupMenu.MENU_TYPE_JPY, digit == 2, digit);popupMenu.showPopupMenu();popupMenu.createPupupWindow().setOnDismissListener(new PopupWindow.OnDismissListener() {@Overridepublic void onDismiss() {}});}});//======================================================================================? ? ? ?(2)隱藏系統自帶的鍵盤,方法如下,需要傳入activity和edittext控件,如下代碼:
/*** 隱藏系統鍵盤* * @param ed* @author qiulinhe* @createTime 2016年5月31日 下午1:50:33*/public static void hideSoftInputMethod(EditText ed, Activity activity) {activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);int currentVersion = android.os.Build.VERSION.SDK_INT;String methodName = null;if (currentVersion >= 16) {// 4.2 methodName = "setShowSoftInputOnFocus";} else if (currentVersion >= 14) {// 4.0 methodName = "setSoftInputShownOnFocus";}if (methodName == null) {ed.setInputType(InputType.TYPE_NULL);} else {Class<EditText> cls = EditText.class;Method setShowSoftInputOnFocus;try {setShowSoftInputOnFocus = cls.getMethod(methodName, boolean.class);setShowSoftInputOnFocus.setAccessible(true);setShowSoftInputOnFocus.invoke(ed, false);} catch (NoSuchMethodException e) {ed.setInputType(InputType.TYPE_NULL);e.printStackTrace();} catch (IllegalAccessException e) {e.printStackTrace();} catch (IllegalArgumentException e) {e.printStackTrace();} catch (InvocationTargetException e) {e.printStackTrace();}}}

? ? ?2.寫好popuwindow的xml布局文件,也就是你需要呈現的鍵盤布局,xml文件如下:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="300dp"android:layout_height="400dp"android:background="#ffffff"android:orientation="vertical"

/></LinearLayout></LinearLayout>

? ?3.接著就是點擊edittext時候,彈出popuwindow窗口的管理類了,如下代碼:

上述的控制類中,就已經有一些關于限制金額的輸入為7位數,限制有些輸入的數據整數位3位/小數為2位的邏輯.很多注釋已經加上,代碼有些是不全的,所以有問題可以交流.

如果出現鍵盤遮擋的問題,可以套一層scrollview或者重新設置listview的高度,如下鏈接:http://blog.csdn.net/nihaoqiulinhe/article/details/51917530
