scrollview

问题 I have a searchView in the middle of fragment. When I tap on it, it expand a keyboard which cover list (which is under the searchView) and place for writing queries (searchView). Is there any possibility to somehow scroll to the top whole layout when tap on search icon? Currently I set all the views above searchView to myViews.visibility = View.GONE and I've received proper behaviour but I am not sure if this is correct - especially since above searchView I have a map. What's your opinion?

问题 I’m after a vertical scrollview that’s infinite both ways: scrolling up to the top or down to the bottom results in more items being added dynamically. Almost all help I’ve encountered is only concerned with the bottom side being infinite in scope. I did come across this relevant answer but it’s not what I’m specifically looking for (it’s adding items automatically based on time duration, and requires interaction with direction buttons to specify which way to scroll). This less relevant

问题 I have a horizontal scrollview with many EditText children. I want each of these children to be the same width of the visible area of the parent scrollview. Is this possible in XML? 回答1: You can do it writing a small helper class: We are creating a very small class that extends EditText called FullWidthEditText like this: package com.YOURPACKAGENAME; import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.widget.EditText; import android

问题 I have a WebView with android:layout_height="wrap_content" inside a ScrollView . Prior to Android 7 this resulted in the WebView resizing to the height of the local html content I set with loadData . On my Nexus 5X with Android 7 though, the WebView height seems to be unreliable, sometimes it only shows parts of the first text line, sometimes there's a big gap at the end of the content. I think it could be due to Google now using Chrome for WebViews starting with Nougat. Does anyone have an
