android - Scrollview - TextView limits in terms of numbers of lines -


my app doing logging , user have run days. in case end out having 100k lines of text scroll through.

this doesn't seem reasonnable. should see memory limits. how many lines of text maintain @ max?

can have rolling textview maintain last 1k lines of text? should textviewwith maxlines of 1k , scrollbar?

at moment have following xml:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context="com.narb.log.mainactivity">      <button         android:id="@+id/btn"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerhorizontal="true"         android:text="start"         />      <scrollview         android:id="@+id/sv"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_margin="10dp"         android:layout_below="@id/btn"         >          <textview             android:id="@+id/txt"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="this log number"             android:layout_margin="15dp"             />     </scrollview> </relativelayout>

if you, set max lines 100 , add read more option @ end of text , when user clicks that, set max lines textview.maxlines + 100 , hide read more when there no more text show.
