之前博客中,介绍过使用谷歌提供的键盘的一些api,能够非常好地自己定义键盘,參考我之前的博客链接: ,这个有一个局限性,仅仅能占满屏幕,无法做到仅仅能占一部分的需求键盘,例如以下图我平板中的键盘需求:(因为公司保密须要,所以比較恐怖一点,嘿嘿)

     相似于上方的左下角的一小块键盘,这就不能使用系统自带的一些键盘api,须要自己写布局,而且对输入的金额进行位数的限制,以及一些栏位输入的整数和小数位的控制,总体的实现过程例如以下;

1.点击某个edittext,弹出下方的键盘(也就是使用popuwindow的方式),须要监听edittext获得焦点以及点击的事件,还须要隐藏掉系统自带的键盘,例如以下:

limitEditText = (EditText) fragmentLayout.findViewById(R.id.ordertrade_limit_price);				//禁止系统键盘弹出		MainActionUtilHelper.hideSoftInputMethod(limitEditText, getActivity());		digit = allone.verbank.apad.client.util.InstrumentUtil.getDigitByInstrument(instName);		limitEditText.setOnFocusChangeListener(new android.view.View.OnFocusChangeListener() {			@Override			public 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() {						@Override						public void onDismiss() {						}					});				} else {					// 此处为失去焦点时的处理内容				}			}		});		//监听弹出数字键盘		limitEditText.setOnClickListener(new OnClickListener() {			@Override			public void onClick(View vi) {				if (popupMenu != null) {					popupMenu.destroyPopupMenu();				}				// 浮出菜单				popupMenu = PopupMenuFactory.createPopupWindowKeyBoard(getActivity(), limitEditText, order_amount_layout,						IPopupMenu.MENU_TYPE_JPY, digit == 2, digit);				popupMenu.showPopupMenu();				popupMenu.createPupupWindow().setOnDismissListener(new PopupWindow.OnDismissListener() {					@Override					public void onDismiss() {					}				});			}		});		//======================================================================================

       (2)隐藏系统自带的键盘,方法例如以下,须要传入activity和edittext控件,例如以下代码:

/**	 * 隐藏系统键盘	 * 	 * @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
      
        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.写好popuwindow的xml布局文件,也就是你须要呈现的键盘布局,xml文件例如以下:

   3.接着就是点击edittext时候,弹出popuwindow窗体的管理类了,例如以下代码:

package allone.verbank.apad.client.component.menu.impl;import allone.verbank.apad.client.R;import allone.verbank.apad.client.component.menu.IPopupMenu;import allone.verbank.apad.client.util.SharepreferencesUtilSystemSettings;import android.app.Activity;import android.graphics.drawable.ColorDrawable;import android.view.Gravity;import

true;				}				return false;			}		});		//初始化键盘上的数字		initALLDig(view);	}	@Override	public PopupWindow createPupupWindow() {		return popupMenu;	}	@Override	public void showPopupMenu() {		if (popupMenu !=

上述的控制类中,就已经有一些关于限制金额的输入为7位数,限制有些输入的数据整数位3位/小数为2位的逻辑.非常多凝视已经加上,代码有些是不全的,所以有问题能够交流.

假设出现键盘遮挡的问题,能够套一层scrollview或者又一次设置listview的高度,例如以下链接:http://blog.csdn.net/nihaoqiulinhe/article/details/51917530
