Android SDK: Show one line at a time and proceed with onClick -

i'm new java , android sdk i'm willing learn. want build app take sentence, or generic string , displays 1 line of text, coded. want proceed "next" line clicking button called "proceed". in short offers read little amount of text @ time , proceed b clicking button.

this how far i've got:

activity_main.xml

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingbottom="@dimen/activity_vertical_margin"     android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     tools:context=".displaymessageactivity"     android:orientation="horizontal" >      <textview         android:id="@+id/text_box"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textsize="50sp"         android:maxlines="1" />      <button         android:id="@+id/next_button"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerhorizontal="true"         android:layout_centervertical="true"         android:text="@string/next"         android:onclick="nextline"         android:textsize="15sp" />  </relativelayout> 

mainactivity.java:

package com.xxx.xxx.xxx;  import android.app.activity; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener; import android.widget.button; import android.widget.textview;  public class mainactivity extends activity {     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);      string s = "iphone swag fanny pack, try-hard master cleanse pop-up elit deserunt vinyl. odio mustache hoodie yolo fap. vegan godard labore tempor. farm-to-table aute craft beer, yolo bicycle rights artisan semiotics. cosby sweater readymade eiusmod consectetur fap stumptown. cliche keytar accusamus blue bottle, wayfarers locavore selfies elit aliqua chillwave lo-fi helvetica enim. irony tofu blog, fap pickled pariatur odio wolf cliche vice sint pitchfork eiusmod cosby sweater polaroid.";     final string[] words = s.split("\\s+");      button b = (button) findviewbyid(r.id.next_button);      b.setonclicklistener(new onclicklistener() {        @override        public void onclick(view v) {            textview tx = (textview) findviewbyid(r.id.text_box);            stringbuilder builder = new stringbuilder();            (string s : words){              builder.append(s+" ");            tx.settext(builder.tostring());        }     }});  }} 

as of no text loaded textview , button loads of text @ once when clicked on no support "reclick" it.

any ideas?

best regards,

update: i've made counter account word should printed on screen. have question: how go make tre words (or number of words) show instead of one? tried fiddle indexranges can't seem hang of it. how mainactivity.java looks now:

package com.xxx.xxx.xxx;  import android.app.activity; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener; import android.widget.button; import android.widget.textview;  public class mainactivity extends activity {      int counter;     string s = "iphone swag fanny pack, try-hard master cleanse pop-up elit deserunt vinyl. odio mustache hoodie yolo fap. vegan godard labore tempor. farm-to-table aute craft beer, yolo bicycle rights artisan semiotics. cosby sweater readymade eiusmod consectetur fap stumptown. cliche keytar accusamus blue bottle, wayfarers locavore selfies elit aliqua chillwave lo-fi helvetica enim. irony tofu blog, fap pickled pariatur odio wolf cliche vice sint pitchfork eiusmod cosby sweater polaroid.";     final string[] words = s.split("\\s+");      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         final textview tx = (textview) findviewbyid(r.id.text_box);         counter = 0;         tx.settext(words[counter]);      button b = (button) findviewbyid(r.id.next_button);      b.setonclicklistener(new onclicklistener() {        @override        public void onclick(view v) {            counter++;            tx.settext(words[counter]);        }     });  }} 

your code assigns textview value on every iteration adding 1 word after each iteration. that's why text loaded.

   public void onclick(view v) {        textview tx = (textview) findviewbyid(r.id.text_box);        stringbuilder builder = new stringbuilder();         (string s : words){          builder.append(s+" ");          tx.settext(builder.tostring());        } 

if want display 1 word per click, make counter acts index words array , increments after every click. , assign "current index word" text field.
