Textbox hidden below keyboard in Android webview

问题

I have created a simple iPhone/Android app, containing a normal webview. This webview calls my website.

On my website there are several forms with input type=text or textarea. I have a problem with those when they are at the bottom of the page!

1) In my iPhone app, the keyboard will automatically appear and push the textbox to the visible area of the phone screen. So there is nothing to do.

2) But in my Android app the textbox will stay at the same place and is eventually hidden by my keyboard. So the only option users have is to type \"blind\".

How can I fix this? Did anyone else meet this problem?

回答1:

This is how I solved the problem. As Venky said, you have to add

android:windowSoftInputMode="adjustResize"

to your tag in the AndroidManifest.xml file. But in our case, it wasn't enough. Make sure you do this as well with your views, webviews etc. Then we finally made it work.

I was getting crazy nothing works android:windowSoftInputMode="adjustResize" may help but be sure to have your app not in full screen.

Removing full screen for my app solved the problem with the layout resize with softkeyboard.

<item name="android:windowFullscreen">false</item>

This would work:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Few things I learnt while solving this issue --- 1. Theme style should not contain Fullscreen True 2. Add android:windowSoftInputMode="adjustResize" 3. Remove android:scrollbars="none" is any.. . Cheers!

In my case the succes achieved by:

Adding below to manifest, webview and fragment:
```
android:windowSoftInputMode="adjustResize"
```

Using NON FullScreen Theme such as below:

<style name="AppTheme" parent="android:Theme.Black.NoTitleBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">false</item>
</style>

NOT using ScrollView over WebView.

For activities in full screen mode, android:windowSoftInputMode="adjustResize" will not work.

https://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_FULLSCREEN

A fullscreen window will ignore a value of SOFT_INPUT_ADJUST_RESIZE for the window's softInputMode field; the window will stay fullscreen and will not resize.

I use the following method in the activity to resize the layout by setting a bottom padding:


    public void adjustResizeOnGlobalLayout(@IdRes final int viewGroupId, final WebView webView) {
        final View decorView = getWindow().getDecorView();
        final ViewGroup viewGroup = (ViewGroup) findViewById(viewGroupId);

        decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
                Rect rect = new Rect();
                decorView.getWindowVisibleDisplayFrame(rect);
                int paddingBottom = displayMetrics.heightPixels - rect.bottom;

                if (viewGroup.getPaddingBottom() != paddingBottom) {
                    // showing/hiding the soft keyboard
                    viewGroup.setPadding(viewGroup.getPaddingLeft(), viewGroup.getPaddingTop(), viewGroup.getPaddingRight(), paddingBottom);
                } else {
                    // soft keyboard shown/hidden and padding changed
                    if (paddingBottom != 0) {
                        // soft keyboard shown, scroll active element into view in case it is blocked by the soft keyboard
                        webView.evaluateJavascript("if (document.activeElement) { document.activeElement.scrollIntoView({behavior: \"smooth\", block: \"center\", inline: \"nearest\"}); }", null);
                    }
                }
            }
        });
    }

Yeah, had the same problem working with Webview, mine was with input filed on modal. Textfield didn't "focus" above the keyboard. The solution was to delay the function call. Hope someone finds this usefull.

   $("body").on("click", ".jstree-search-input", function () {  

    setTimeout(function(){ 
        androidScroll(); 
    }, 500);
    });

As you can see it's used for jstree input...

   function androidScroll() {
    // Webview focus call (pushes the modal over keyboard)
        $('.control-sidebar-open ').scrollTop($('.control-sidebar-open ')[0].scrollHeight);

}

Beware that apart from the suggest answers

android:windowSoftInputMode="adjustResize"

Is not working when you are in immersive mode
