全屏模式下输入框被遮挡问题处理

Android 全屏模式下输入框被遮挡问题处理

前些天,在做一个页面表单输入需求时,由于我们项目添加了全屏沉浸式状态栏,所以遇到了键盘挡住输入框的问题,简单处理了一下,又发现即使做到键盘不遮挡输入框,又会把页面顶上去,看起来及其不美观。

具体情况如下:

情况一:键盘挡住输入框
键盘挡住输入框

情况二:页面整体被顶上去

添加代码如下:

 <activity
            android:name=".activity.AddGoldActivity"
            android:windowSoftInputMode="adjustPan|stateHidden" />

页面整体被顶上去

下面是解决方案

先来看一下实现后的效果:

解决思路:监测到键盘弹起时,重新绘制页面

  1. 导入:InputHandleUtil 工具类,之前导入 ZyFrame 框架的小伙伴,可以直接调用

    框架地址:https://github.com/Sunnyfor/ZyFrame 点击查看

    在线依赖:implementation ‘com.github.Sunnyfor:ZyFrame:1.4.3’

  2. 调用:InputHandleUtil().handleInputView(rootView, scrollView, ignoreView)

    参数说明:

    (1)rootView:必传参数,系统的根布局view (android.R.id.content)
    (2)scrollView:非必传,包含 EditText 的 ScrollView
    (3)ignoreView:非必传,想要忽略的View,键盘弹出时,不显示此 view,例如:底部提交按钮
    注:后两个参数是配合使用的

效果一:
InputHandleUtil().handleInputView(rootView)
效果一

效果二:
InputHandleUtil().handleInputView(rootView, scrollView, ignoreView)
效果二
效果三:对于底部是输入框的情况也同样适用

工具类代码如下:
