如何在 WebView 中禁用软键盘 [英] How disable softkeyboard in WebView
问题描述
我需要在我的 WebView 和 WebView 中的所有编辑文本中禁用打开软键盘(我无法访问它,因为它在 WebView 中).
我尝试在我的 Manifest 文件中使用 'android:windowSoftInputMode="stateAlwaysHidden"',但当我点击可编辑字段时键盘弹出.
在 WebView 中禁用软键盘的正确解决方案是什么?
我找到了解决方案(感谢这篇文章中的@g00dy 和 https://stackoverflow.com/a/9108219/1665964) 打开后关闭键盘:
公共类ActivityBrowser扩展Activity{私有静态 WebView webviewHTML;私有静态视图 viewRootHTML;私有静态 int iViewRootHTMLHeightDifferent;公共静态上下文上下文浏览器;{上下文浏览器 = 这个;}公共类 webViewClient 扩展了 WebViewClient{@覆盖public void onPageStarted(WebView 视图、字符串 URL、位图图标){if( view == webviewHTML) super.onPageStarted( view, url, favicon);}@覆盖public void onPageFinished(WebView view, String url){if( view == webviewHTML) super.onPageFinished( view, url);}@覆盖public boolean shouldOverrideUrlLoading(WebView view, String url){if(view == webviewHTML) view.loadUrl( url);返回假;//返回 super.shouldOverrideUrlLoading( view, url);}@覆盖public void onReceivedError(WebView view, int errorCode, String description, String failedUrl){if( view == webviewHTML) ApplicationLeta.fPopup( getString( R.string.sPopupErrorSiteOpen) + " : " + description);//ActivityBrowser.this.finish();}public void onReceivedSslError(WebView 视图,SslErrorHandler 处理程序,SslError 错误){if( view == webviewHTML) handler.proceed();}}@覆盖公共布尔 dispatchTouchEvent(MotionEvent 运动事件){super.dispatchTouchEvent(motionEvent);if(motionEvent.getAction() == MotionEvent.ACTION_MOVE) 返回真;if(motionEvent.getAction() == MotionEvent.ACTION_UP){//做一点事}if(motionEvent.getAction() == MotionEvent.ACTION_UP){//做一点事}返回假;}@覆盖公共无效 onBackPressed(){}@覆盖public void onWindowFocusChanged(boolean eFocus){super.onWindowFocusChanged(eFocus);if(eFocus == false){fKeyboardClose();新线程(新可运行(){@覆盖公共无效运行(){尝试{Instrumentation inst = new Instrumentation();inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);}捕获(异常 e){}}} ).开始();}}私有无效 fKeyboardClose(){InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);inputMethodManager.hideSoftInputFromWindow( getCurrentFocus().getWindowToken(), 0);}public OnGlobalLayoutListener onGlobalLayoutListener = new OnGlobalLayoutListener(){@覆盖公共无效 onGlobalLayout(){矩形矩形 = 新矩形();viewRootHTML.getWindowVisibleDisplayFrame(rect);iViewRootHTMLHeightDifferent = viewRootHTML.getRootView().getHeight() - (rect.bottom - rect.top);if(iViewRootHTMLHeightDifferent > 50) fKeyboardClose();}};@SuppressWarnings(弃用")@SuppressLint("SetJavaScriptEnabled")public void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.browser);if(savedInstanceState == null){viewRootHTML = findViewById( R.id.linearLayoutHTML);viewRootHTML.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);webviewHTML = (WebView) findViewById( R.id.webviewHTML);WebSettings webSettings = webviewHTML.getSettings();webSettings.setJavaScriptEnabled(true);webSettings.setJavaScriptCanOpenWindowsAutomatically(true);webviewHTML.setWebViewClient(new wiewClient());webviewHTML.loadUrl(ApplicationLeta.sAppInterviewURL);}}}
当用户长按输入字段时,此代码还会关闭系统消息编辑文本/输入法".
但是!此代码仅在打开后关闭键盘.键盘保持可见几毫秒,用户(快速用户)可以按键盘上的任意键.这不是最好的情况.
也许存在无需打开键盘即可 100% 禁用键盘的最佳方法?

<块引用>在 layout.xml 的主(父)布局中添加以下代码:
>>android:descendantFocusability="blocksDescendants">
<块引用>
并在您的 webview 中设置以下属性:
>机器人:焦点=假">android:focusableInTouchMode="true"
I need disable open softkeyboard in my WebView and in all edittexts in WebView (I do not access to thay because its is in WebView).
I try use 'android:windowSoftInputMode="stateAlwaysHidden"' in my Manifest file, but keyboard popup on when I click in editable field.
What is right solution for disable softkeyboard in WebView?
EDIT:
I find solution (thanks @g00dy in this post and @Kachi in post https://stackoverflow.com/a/9108219/1665964) for close keyboard after it open:
public class ActivityBrowser extends Activity
{
private static WebView webviewHTML;
private static View viewRootHTML;
private static int iViewRootHTMLHeightDifferent;
public static Context contextBrowser;
{
contextBrowser = this;
}
public class webViewClient extends WebViewClient
{
@Override
public void onPageStarted( WebView view, String url, Bitmap favicon)
{
if( view == webviewHTML) super.onPageStarted( view, url, favicon);
}
@Override
public void onPageFinished( WebView view, String url)
{
if( view == webviewHTML) super.onPageFinished( view, url);
}
@Override
public boolean shouldOverrideUrlLoading( WebView view, String url)
{
if( view == webviewHTML) view.loadUrl( url);
return false;
// return super.shouldOverrideUrlLoading( view, url);
}
@Override
public void onReceivedError( WebView view, int errorCode, String description, String failingUrl)
{
if( view == webviewHTML) ApplicationLeta.fPopup( getString( R.string.sPopupErrorSiteOpen) + " : " + description);
// ActivityBrowser.this.finish();
}
public void onReceivedSslError( WebView view, SslErrorHandler handler, SslError error)
{
if( view == webviewHTML) handler.proceed();
}
}
@Override
public boolean dispatchTouchEvent( MotionEvent motionEvent)
{
super.dispatchTouchEvent( motionEvent);
if( motionEvent.getAction() == MotionEvent.ACTION_MOVE) return true;
if( motionEvent.getAction() == MotionEvent.ACTION_UP)
{
// do something
}
if( motionEvent.getAction() == MotionEvent.ACTION_UP)
{
// do something
}
return false;
}
@Override
public void onBackPressed()
{
}
@Override
public void onWindowFocusChanged( boolean eFocus)
{
super.onWindowFocusChanged( eFocus);
if( eFocus == false)
{
fKeyboardClose();
new Thread( new Runnable()
{
@Override
public void run()
{
try
{
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync( KeyEvent.KEYCODE_BACK);
}
catch( Exception e) {}
}
} ).start();
}
}
private void fKeyboardClose()
{
InputMethodManager inputMethodManager = (InputMethodManager)getSystemService( Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow( getCurrentFocus().getWindowToken(), 0);
}
public OnGlobalLayoutListener onGlobalLayoutListener = new OnGlobalLayoutListener()
{
@Override
public void onGlobalLayout()
{
Rect rect = new Rect();
viewRootHTML.getWindowVisibleDisplayFrame( rect);
iViewRootHTMLHeightDifferent = viewRootHTML.getRootView().getHeight() - (rect.bottom - rect.top);
if( iViewRootHTMLHeightDifferent > 50) fKeyboardClose();
}
};
@SuppressWarnings( "deprecation")
@SuppressLint( "SetJavaScriptEnabled")
public void onCreate( Bundle savedInstanceState)
{
super.onCreate( savedInstanceState);
setContentView( R.layout.browser);
if( savedInstanceState == null)
{
viewRootHTML = findViewById( R.id.linearLayoutHTML);
viewRootHTML.getViewTreeObserver().addOnGlobalLayoutListener( onGlobalLayoutListener);
webviewHTML = (WebView) findViewById( R.id.webviewHTML);
WebSettings webSettings = webviewHTML.getSettings();
webSettings.setJavaScriptEnabled( true);
webSettings.setJavaScriptCanOpenWindowsAutomatically( true);
webviewHTML.setWebViewClient( new wiewClient());
webviewHTML.loadUrl( ApplicationLeta.sAppInterviewURL);
}
}
}
This code also close system message "Edit text / Input method" when user longpress on input field.
But! This code close keyboard only after it open. Keyboard stay visible a few miliseconds and user (fast user) can press any key on keyboard. This is not best situation.
Maybe exist best way to 100% disable keyboard without open it?
This answer worked for me (provided by Android Weblineindia): https://stackoverflow.com/a/29409478/4813198
Add following code in main (parent) layout in your layout.xml:
>
> android:descendantFocusability="blocksDescendants"
>
and set following properties in your webview:
> android:focusable="false"
> android:focusableInTouchMode="true"
