Android EditText不显示键盘
我有一个FragmentActivity,它加载一个RelativeLayout,在EditText和按钮上方有一个ListView。我似乎无法让键盘以任何方式显示出来。当我触摸它或设置焦点时,什么都没有发生。当我自动请求焦点时,什么也没有发生。如何让键盘显示出来?这不是应该是自动的吗?我想模拟GTALK的聊天输入 活动\u联系人\u chat.xml:Android EditText不显示键盘,android,android-layout,Android,Android Layout,我有一个FragmentActivity,它加载一个RelativeLayout,在EditText和按钮上方有一个ListView。我似乎无法让键盘以任何方式显示出来。当我触摸它或设置焦点时,什么都没有发生。当我自动请求焦点时,什么也没有发生。如何让键盘显示出来?这不是应该是自动的吗?我想模拟GTALK的聊天输入 活动\u联系人\u chat.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:a

当活动获得焦点时,您可以使用以下任一方法显示软键盘:
您可以向布局xml中的EditText添加以下代码:
android:focusable="true"
android:focusableInTouchMode="true"
另外,您可以在代码中将其设置为
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
或者
移除
android:descendantFocusability="blocksDescendants"
主要是相对论。您将在Edittext中获得焦点。BlockSubstands将阻止子布局获得焦点。检查您是在模拟器中测试还是在设备中测试?两者都有。一个Droid RAZR、摩托罗拉XOOM和一个N7模拟器(512 MB)。所以键盘显示不是自动的?我不明白为什么这是“太本地化”。这样做了,2分钟后就可以接受了。我真不敢相信我错过了,太好了。你救了我的命。谢谢谢谢你救了我一天谢谢@Sahil。。你救了我一天:)谢谢分享它对我不起作用仍然看不到键盘小心显式设置android:inputType,否则键盘将无法打开。
android:descendantFocusability="blocksDescendants"
