How do I show text and a button? (android) -

i'm working on app generates random quote (from switch) when press button. goes next screen, displays textview. part works. want button under this, send user main screen (i plan on having 2 other buttons come later). however, app displaying either text or button, not both.

    protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_comp_out);     intent intent = getintent();     string message = intent.getstringextra(mainactivity.extra_message);      // create text view     textview textview = new textview(this);     textview.settextsize(40);     textview.settext(message);      button button = new button(this);     button.settext("main menu");     button.settextcolor(color.parsecolor("#ff0000"));     button.setheight(75);       // set text view activity layout     setcontentview(textview);     setcontentview(button); } 

this code i'm using create text output , button. string message quote. code making button fills whole screen though.

<linearlayout 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:orientation="vertical"  android:background="@color/orange">  <button     android:id="@+id/button1"     android:layout_width="match_parent"     android:layout_height="50dp"     android:layout_marginend="5dp"     android:layout_marginstart="5dp"     android:layout_margintop="5dp"     android:textcolor="@color/blue"     android:text="@string/button_menu" />  </linearlayout> 

without java code making button, using this, wasn't making button either. (also background wasn't being set orange, thats not big deal) ideas on how put button under text?

you have 3 setcontentview() instructions (the second , third override first one, why see button - 1 define in code - , don't orange background, anymore).
there must 1.

this instruction used set activity (or fragment) layout should contain both components.

try this:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_comp_out);      textview textview = (textview) findviewbyid(r.id.text1);     button button = (button) findviewbyid(r.id.button1);      // add click handler button - choose 1 of possible methods (see link @ end of answer).      // following instructions should go inside click handler.     intent intent = getintent();     string message = intent.getstringextra(mainactivity.extra_message); } 

activity_comp_out.xml

<linearlayout     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:orientation="vertical"      android:background="@color/orange"     >     <textview         android:id="@+id/text1"         android:layout_width="match_parent"         android:layout_height="50dp"         android:layout_marginend="5dp"         android:layout_marginstart="5dp"         android:layout_margintop="5dp"         android:textcolor="@color/blue"         android:text="@string/text_menu"     />     <button         android:id="@+id/button1"         android:layout_width="match_parent"         android:layout_height="50dp"         android:layout_marginend="5dp"         android:layout_marginstart="5dp"         android:layout_margintop="5dp"         android:textcolor="@color/blue"         android:text="@string/button_menu"     /> </linearlayout>
