Implementation method:

One: Customizing a component that contains EditText and buttons

Create an XML layout file for a Buttonext_layout custom component first

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "Horizontal">    <EditTextAndroid:id= "@+id/edittext"Android:layout_width= "0DP"Android:layout_weight= "1"Android:layout_height= "Wrap_content"Android:inputtype= "text"/>    <ButtonAndroid:id= "@+id/clearbutton"Android:layout_width= "0DP"Android:layout_weight= "1"Android:layout_height= "Wrap_content"Android:text= "Clear"/></LinearLayout>

Two: Create a custom control class Butext

 public class Butext extends LinearLayout {private EditText medittext;    Private Button Mbutton;        Public Butext (Context context) {super (context);         Populate the view with layout resources Layoutinflater Minflater = (layoutinflater) context.getsystemservice (Context.layout_inflater_service);        Load Layout file Minflater.inflate (R.layout.buttonext_layout, this, true);        Medittext = (EditText) Findviewbyid (R.id.edittext);        Mbutton = (Button) Findviewbyid (R.id.clearbutton);    Hookupbutton (context); }/** * Button handler */private void Hookupbutton (final context context) {Mbutton.setonclicklistener (n EW View.onclicklistener () {@Override public void OnClick (View v) {Medittext.settext                ("");            Toast.maketext (Context, "text box data cleared", Toast.length_short). Show ();    }        }); /** 
 * Assign value to edittext 
 */
  

    public void SetText (String txt) {
       Medittext.settext (TXT);
    }

}

Three: Realization of mainactivity class

 Public classMainactivityextendsappcompatactivity {PrivateLinearLayout mlinearlayout; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); //dynamic Additions to our custom componentsMlinearlayout =(LinearLayout) Findviewbyid (r.id.main_layout);  for(inti = 0; I < 3; i++) {Imageviewext EditText=NewImageviewext ( This);
Edittext.settext (i+ ");        Mlinearlayout.addview (EditText); }    }}
