之前博客中,介绍过使用谷歌提供的键盘的一些api,可以很好地自定义键盘,参考我之前的博客链接:android 自定义键盘 ,这个有一个局限性,只能占满屏幕,无法做到只能占一部分的需求键盘,如下图我平板中的键盘需求:(由于公司保密需要,所以比较恐怖一点,嘿嘿)
类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,需要自己写布局,并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,整体的实现步骤如下;
1.点击某个edittext,弹出下方的键盘(也就是使用popuwindow的方式),需要监听edittext获得焦点以及点击的事件,还需要隐藏掉系统自带的键盘,如下:
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,方法如下,需要传入activity和edittext控件,如下代码:/**

if (currentVersion >= 16) {
// 4.2

} else if (currentVersion >= 14) {

}
if (methodName == null) {

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.很多注释已经加上,代码有些是不全的,所以有问题可以交流.
