Android5.0 沉浸式效果导致Edittext获取焦点后画面不动的问题
来源:互联网 发布:社交软件 日语怎么说 编辑:程序博客网 时间:2024/06/01 18:50
在不使用沉浸式效果的情况下,解决此问题只需将
Androidmanifest的activity设置成
android:windowSoftInputMode="adjustResize|stateHidden"
可以解决。
但使用沉浸式效果后,此属性导致画面不移动,效果是软键盘会将Edittext挡住。
百度搜的解决方案是沉浸式的代码使用第三方类库SystemBarTintManager类。
具体类的代码如下 :

使用方法如下:
public void ProcessingNoticationbar() {setTranslucentStatus(true);SystemBarTintManager tintManager = new SystemBarTintManager(this);tintManager.setStatusBarTintEnabled(true);tintManager.setStatusBarTintResource(R.color.main_title_background);//通知栏所需颜色}private void setTranslucentStatus(boolean on) {Window win = getWindow();WindowManager.LayoutParams winParams = win.getAttributes();final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;if (on) {winParams.flags |= bits;} else {winParams.flags &= ~bits;}win.setAttributes(winParams);}
而且需要在该布局的根节点上加入
android:fitsSystemWindows="true"
很给力的解决了问题。
下面为windowSoftInputMode的具体属性:
<activity android:windowSoftInputMode=["stateUnspecified",
"stateUnchanged", "stateHidden",
"stateAlwaysHidden", "stateVisible",
"stateAlwaysVisible", "adjustUnspecified",
"adjustResize", "adjustPan"] …… >
"stateUnspecified" 软键盘的状态(是否它是隐藏或可见)没有被指定。系统将选择一个合适的状态或依赖于主题的设置。这个是为了软件盘行为默认的设置。
"stateUnchanged" 软键盘被保持无论它上次是什么状态,是否可见或隐藏,当主窗口出现在前面时。
"stateHidden" 当用户选择该Activity时,软键盘被隐藏——也就是,当用户确定导航到该Activity时,而不是返回到它由于离开另一个Activity。
"stateAlwaysHidden" 软键盘总是被隐藏的,当该Activity主窗口获取焦点时。
"stateVisible" 软键盘是可见的,当那个是正常合适的时(当用户导航到Activity主窗口时)。
"stateAlwaysVisible" 当用户选择这个Activity时,软键盘是可见的——也就是,也就是,当用户确定导航到该Activity时,而不是返回到它由于离开另一个Activity。
"adjustUnspecified" 它不被指定是否该Activity主窗口调整大小以便留出软键盘的空间,或是否窗口上的内容得到屏幕上当前的焦点是可见的。系统将自动选择这些模式中一种主要依赖于是否窗口的内容有任何布局视图能够滚动他们的内容。如果有这样的一个视图,这个窗口将调整大小,这样的假设可以使滚动窗口的内容在一个较小的区域中可见的。这个是主窗口默认的行为设置。
"adjustResize" 该Activity主窗口总是被调整屏幕的大小以便留出软键盘的空间。
"adjustPan" 该Activity主窗口并不调整屏幕的大小以便留出软键盘的空间。相反,当前窗口的内容将自动移动以便当前焦点从不被键盘覆盖和用户能总是看到输入内容的部分。这个通常是不期望比调整大小,因为用户可能关闭软键盘以便获得与被覆盖内容的交互操作。
