在 WebView 中禁用 SoftKeyboard [英] Disable SoftKeyboard inside a WebView
问题描述
我知道这是一个常见问题,但我无法在此处和 Google 上找到有效的解决方案.
I know this is a common question but I can't find here and on Google, a functioning solution.
我的 android 应用中有一个 WebView,里面有一个 JSF 页面,里面有一个简单的 DatePicker 组件:
I have a WebView in my android app with a JSF page inside with a simple DatePicker component:
<p:calendar value="#{patientHealthDataView.dateFrom}" id="popupButtonDateFrom" showOn="button" class="tableCalendarText"/>
显示带有日历的弹出窗口.
that show a Popup with calendar.
多亏了这个命令,我才设法使弹出窗口正常工作:
Thanks to this command, I manage to make the popup works:
WebView view=(WebView)findViewById(R.id.statistics);
view.getSettings().setJavaScriptEnabled(true);
不幸的是,当我点击输入文本或按钮以显示日历的弹出窗口时,焦点转到输入文本,Android 显示其隐藏日历的键盘.
Unfortunally, when I click on input text or the button to show the calendar's popup, the focus goes to Input Text and Android show its keyboard hiding the calendar.
我尝试了几种解决方案.最后一个是这样的:
I've tried several solution. The last one was this:
view.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
hideSoftKeyboard(v);
return false;
}
});
public void hideSoftKeyboard(View v) {
Activity activity = (Activity) v.getContext();
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
此代码,按照 Android Studio 的建议,在以下位置引发空指针异常:
This code, as suggested by Android Studio, raise a Null Pointer Exception on:
activity.getCurrentFocus().getWindowToken()
其他解决方案说要在清单中插入特殊命令,但我只想在 WebView 中阻止键盘.
Other solutions says to insert a special command in manifest but I want to block the keyboard only in the WebView.
有什么建议吗?
推荐答案
在 layout.xml 的 main(parent) 布局中添加以下代码
Add following code in main(parent) layout in your layout.xml
android:descendantFocusability="blocksDescendants"
希望它会奏效.
并在您的 webview 中设置以下属性
and set following property in your webview
android:focusable="false"
android:focusableInTouchMode="true"
