如何在WebView中禁用软键盘

Question

我需要在我的WebView和WebView的所有edittexts中禁用打开软键盘(我不能访问因为它在WebView中).

我尝试在我的清单文件中使用'android:windowSoftInputMode ="stateAlwaysHidden"',但是当我点击可编辑字段时键盘弹出.

什么是在WebView中禁用软键盘的正确解决方案？

我发现解决方案(在这篇文章中感谢@ g00dy,在/sf/answers/637575361/后感谢@Kachi )打开后关闭键盘:

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);
        }
    }
 }

当用户在输入字段上长按时,此代码也会关闭系统消息"编辑文本/输入法".

但!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.

也许存在最好的方法100%禁用键盘而不打开它？

这个答案对我有用(由Android Weblineindia提供):https://stackoverflow.com/a/29409478/4813198

在layout.xml中的main(父)布局中添加以下代码:

>
>    android:descendantFocusability="blocksDescendants"
>

并在webview中设置以下属性:

>    android:focusable="false"
>    android:focusableInTouchMode="true"

Answer 2

对于键盘隐藏状态：

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);
        }

要禁用EditTexts：

在活动中设置android:editable="false"它们的布局。EditText.setFocusable(false)

编辑：

要检测使用中的点击事件WebView：

 mWebView.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            // The code of the hiding goest here, just call hideSoftKeyboard(View v);
            return false;  
            }     
        });
