Tapping form field in WebView does not show soft keyboard
I created my开发者_如何转开发 own WebView and set the WebChromeClient and WebViewClient objects. When I start this WebView, the HTML form fields react when I touch them (a cursor appears), but they do not get selected, nor does the soft keyboard start. If I use the trackball to choose the form and press it, the keyboard does appear.
I tried to call myWebview.requestFocusFromTouch()
as this answer suggested, but it returns false and doesn't help.

Here is a fix in case other were not clear.
webview.requestFocus(View.FOCUS_DOWN);
webview.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_UP:
if (!v.hasFocus()) {
v.requestFocus();
}
break;
}
return false;
}
});
Agreed 10% with Dv_MH's answer. However, the attached class was a little excessive. All I needed to do was extend WebView & return true for onCheckIsTextEditor()
import android.content.Context;
import android.util.AttributeSet;
import android.webkit.WebView;
public class LiveWebView extends WebView {
public LiveWebView(Context context) {
super(context);
}
public LiveWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public LiveWebView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public boolean onCheckIsTextEditor() {
return true;
}
}
From there, I was able to use it as a normal WebView (even in Dialogs).
Alternatively, with less code:
WebView web = new WebView(context) {
@Override
public boolean onCheckIsTextEditor() {
return true;
}
};
IMPORTANT I spent hours searching for this and I solved it by making sure that parent layout that extends "ViewGroup" doesn't have property
android:descendantFocusability = "blocksDescendants" which prevent child layout from getting focused
OR Add android:focusable="true" to webview
AndroidChen's answer did not work for me at all, but I searched the link provided (http://code.google.com/p/android/issues/detail?id=7189) and I found the following class, it works perfectly (Android Froyo on HTC Bravo), not just text, but also all buttons, redirects, etc, everything works perfectly :D
class LiveWebView extends WebView
{
Context mContext;
public LiveWebView(Context context, String URL)
{
super(context);
mContext = context;
setWebViewClient(URL);
}
@Override
public boolean onCheckIsTextEditor()
{
return true;
}
@SuppressLint("SetJavaScriptEnabled")
boolean setWebViewClient(String URL)
{
setScrollBarStyle(SCROLLBARS_INSIDE_OVERLAY);
setFocusable(true);
setFocusableInTouchMode(true);
requestFocus(View.FOCUS_DOWN);
WebSettings webSettings = getSettings();
webSettings.setSavePassword(false);
webSettings.setSaveFormData(false);
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(false);
webSettings.setUseWideViewPort(false);
setOnTouchListener(new View.OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
switch (event.getAction())
{
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_UP:
if (!v.hasFocus())
{
v.requestFocus();
}
break;
}
return false;
}
});
this.setWebViewClient(new WebViewClient()
{
ProgressDialog dialog = new ProgressDialog(mContext);
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
loadUrl(url);
return true;
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
Toast.makeText(mContext, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
if (dialog != null)
{
dialog.setMessage("Loading...");
dialog.setIndeterminate(true);
dialog.setCancelable(true);
dialog.show();
}
}
public void onPageFinished(WebView view, String url)
{
if (dialog != null)
{
dialog.cancel();
}
}
});
this.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
}
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result)
{
result.confirm();
return true;
}
});
loadUrl(URL);
return true;
}
}
and then to create a webview within a dialog, I wrote this code
AlertDialog.Builder alert = new AlertDialog.Builder(M_PaymentOptions.this);
alert.setNegativeButton("Back to Payment Options", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int id)
{}
});
alert.setTitle("BarclayCard Payment");
LiveWebView liveWevViewObject = new LiveWebView(M_PaymentOptions.this, redirecturl);
alert.setView(liveWevViewObject);
alert.show();
Just add invisible EditText under WebView
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible" />
<WebView
android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
All these focus-related solutions didn't work on my Samsung Note 3/Android 5.0
As mentioned here on Google Issue Tracker this fix works fine. Nothing else needed.
webView.isFocusable = true
webView.isFocusableInTouchMode = true
webView.requestFocus(View.FOCUS_DOWN)
For anyone who is having this in a DialogFragment (or maybe a Dialog in general), this may be related to this bug: https://issuetracker.google.com/issues/36915710
Here's the workaround which worked for me:
https://stackoverflow.com/a/16573061/1316677
Summary: create an invisible/"gone" EditText in the layout in the Dialog, then call:
EditText edit = view.findViewById(R.id.editText);
edit.setFocusable(true);
edit.requestFocus();
In my case (Set top / Media Player type device with Android 7.1.1) none of these solutions were needed.
It turns out that having a physical keyboard plugged in prevents the soft keyboard from showing by default. Make sure you unplug any physical keyboards (or anything that presents itself as a keyboard) from the device before attempting to test your webivew. By default soft keyboard will not show if there is a physical keyboard detected.
