Android 平板中 自己定义键盘(popuwindow) 居于屏幕左下方 仿微信的password输入界面

时间：2021-07-24 21:00:58

      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:android 自己定义键盘 ,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)

Android 平板中 自己定义键盘(popuwindow) 居于屏幕左下方 仿微信的password输入界面

     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<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.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:

<?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"

    <TextView

        android:layout_height="30dp"

        android:background="@drawable/keyboardblow" />

    <LinearLayout

        android:layout_width="fill_parent"

        android:layout_height="40dp"

        android:layout_gravity="center_horizontal"

        android:layout_margin="2px"

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
