Android uses Horizontalscrollview to achieve title drive content left and right cutting screen

Add <HorizontalScrollView> tags to the layout,

<Relativelayoutxmlns: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"Tools:context=". Mainactivity " >    <HorizontalscrollviewAndroid:id= "@+id/horizontalscrollview1"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:layout_alignparentleft= "true"Android:layout_alignparenttop= "true"   >     </Horizontalscrollview> </Relativelayout>

Note: Here you add a linearlayout layout directly to the Horizontalscrollview in the layout,

  Final LinearLayout layout = new LinearLayout (this);

Logic code, by adding a horizontalscrollview to the

A linearlayout that adds a child view to the LinearLayout

 Public classMainactivityextendsActivity {PrivateHorizontalscrollview HSV; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); HSV=(Horizontalscrollview) Findviewbyid (R.ID.HORIZONTALSCROLLVIEW1);    Initview (); }      Public voidInitview () {string[] mtexts= {                "Focus", "domestic", "foreign", "military",                 "Focus", "domestic", "foreign", "military", "more"        }; Final LinearLayout layout = new LinearLayout (this);
Add Child view
 for(inti = 0; i < mtexts.length; i++) {Button btn=NewButton ( This);            Btn.setid (i);            Btn.settext (Mtexts[i]);        Layout.addview (BTN);    } hsv.addview (layout); }}
