[0.21] [Android] Can't select text inside a TextView

[cyril.gantzer]

I don’t know if it has anything to do with the caret-at-the-end-of-input bug fix, but as of 0.21 I can neither move the caret inside a TextView (usually achieved by holding your finger to the screen for a while then moving it) nor select a portion of text, to cut or copy it (although I suspect this is a result of the first issue).

Hi cyril,

Is this target specific or is it happening in preview and on device?

[cyril.gantzer]

It was on Android Preview but the issue has gone away since then

Actually scratch that, I still have the bug. It’s just not happening on every TextView, just one specific one. It’s really hard to debug, but I finally found what was causing it. At the end of my .ux page, I have these lines:

<WhileInactive>
    <Change PairMessagingPage.Visibility="Collapsed" Delay="0.2" />
</WhileInactive>

If I delete the Change, the bug disappears. I need this node, as this is how I navigate between different pages. I don’t see any easy workaround, but maybe you get an idea of the root cause?

Full repro example (try selecting text in the TextView: no cursor):

<App>
<JavaScript>
    var Observable = require('FuseJS/Observable');
    var currentPage = Observable('First');

    module.exports = {
        currentPage: currentPage,
        navigate: function () {
            currentPage.value = 'Second';
        }
    }
</JavaScript>
<DirectNavigation ux:Name="NavMain" Active="{currentPage}" />
<Page ux:Name="First" Background="Red">
    <Tapped>
        <Callback Handler="{navigate}" />
    </Tapped>
    <WhileInactive>
        <Change First.Opacity="0" Duration="0.2" />
        <Change First.Visibility="Collapsed" Delay="0.2" />
    </WhileInactive>
</Page><Page ux:Name="Second" Background="White">
    <TextView ux:Name="GroupMessageInput" TextWrapping="Wrap" Padding="6,6,0,6" Value="Hi this is some kind of Lorem Ipsum that will get big enough so that it wraps around once or twice…" />
    <WhileInactive>
        <Change Second.Opacity="0" Duration="0.2" />
        <Change Second.Visibility="Collapsed" Delay="0.2" />
    </WhileInactive>
</Page>
</App>

I’ve bumped this internally as I’m seeing a similar issue on the latest version. For me I can select but only after the device has rotated once. Sounds nasty.

Were on it though

What device is this failing on? I can select text without problems at first try and also after reloads.

[cyril.gantzer]

Nexus 5. Same behavior as Chris though: if I rotate the device, it works (and if I rotate it back to initial position, it’s fixed).

Hmm, this is very strange. My first test was on my Nexus 5, and there it works. I just tested on a Nexus 9 tablet, and there the bug does trigger as described. Kinda feels like something weird is going on in Android. Changing Second.Visibility="Collapsed" to Second.Visibility="Hidden" makes it work. You can use that as a fix in the meantime, it might take some time to track down the bug here.
