How do I completely prevent a TextView from scrolling?
android, android-layout, android-scroll, textview
Solution
I have the same problem,My solution is create a NoScrollTextView extends TextView like this
public class NoScrollTextView extends TextView {
public NoScrollTextView(Context context) {
super(context);
}
public NoScrollTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NoScrollTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public NoScrollTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
@Override
public void scrollTo(int x, int y) {
//do nothing
}
}
set scrollTo do nothing
In Kotlin:
class NonScrollingTextView : TextView {
constructor(context: Context) : super(context) {}
constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {}
constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int) : super(context, attrs, defStyleAttr) {}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int, defStyleRes: Int) : super(context, attrs, defStyleAttr, defStyleRes) {
}
override fun scrollTo(x: Int, y: Int) {
//do nothing
}
}
Problem
I have a TextView with a lot of text. This TextView has `maxLines` set, so it only shows the first 8 or so lines. I also have a "Read More" button so I handle expanding the TextView on my own. My problem is that sometimes the TextView scrolls a little (just half a line at a time), even though I never specified any scroll bars. This issue is made worse because the TextView is inside a ListView, so when the user scrolls the main ListView, the TextView sometimes scrolls a little, like this: How do I prevent the TextView from scrolling?
