Android 平板中 自定义键盘(popuwindow) 居于屏幕左下方 仿微信的密码输入界面

标签：

      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() {

					}
				});
			}
		});
