I think maybe that's happened because of my phone in Hebrew and my computer in English.

Answer 1

This is most likely happening because the <application> tag in your AndroidManifest.xml file specifies android:supportsRtl="true". Assuming this attribute is there, any time the user (i.e. you) has their phone set to a right-to-left language, the contents of your LinearLayouts will be reversed.

You can set this attribute to false or you can add android:layoutDirection="ltr" to your LinearLayouts.
