    </LinearLayout>
</RelativeLayout>

When the keyboard is not up I can see every element but whenever the keyboard comes up the ScrollView does not scroll down to reveal the covered elements. I have read through StackOverflow and added android:windowSoftInputMode="stateHidden|adjustResize" to the AndroidManifest.xml but it still does not work.

What happens to be the problem and how can I fix it?

Answer 1

Please try to set android:layout_height="match_parent" on the root element.

Your root element has android:layout_height="wrap_content" (calculate your height based on your children) and it's main child has android:layout_height="match_parent" (calculate your height based on your parent). It looks like chicken and egg problem and I suppose that's why it works on some devices and on some others it doesn't.

To be honest, I haven't tried if this works, but that's what I concluded. If it doesn't help, I'll give it another look.

已修复，问题是在LinearLayout中使用了上边距而不是为元素填充，这显然是一个问题。
