Android : Disable zoom when user press input

Tell me how to Disable zoom when pressing input in webview? Insert here the following line in oncreate, but it still increases when entering the password

    mWebView.getSettings().setDefaultZoom(WebSettings.ZoomDensity.CLOSE);
// it is my code
    mWebView.getSettings().setLoadsImagesAutomatically(false);
    mWebView.getSettings().setLoadWithOverviewMode(false);
    mWebView.getSettings().setUseWideViewPort(false);
    mWebView.setWebViewClient(new HelloWebViewClient());
    mWebView.getSettings().setBuiltInZoomControls(false);
    mWebView.getSettings().setSupportZoom(false);
    mWebView.getSettings().setDefaultZoom(WebSettings.ZoomDensity.CLOSE);
    mWebView.setInitialScale(180);
