This is android studio.

How do I populate my listview using input via Edittext from one activity to another. I need to be able to input names in one activity to be stored in my listview array in another activity. This is what I have so far:

addplayer.java

import android.app.Activity; import java.util.ArrayList; import android.view.View; import android.widget.ArrayAdapter; import android.widget.EditText; import android.widget.ListView; import android.os.Bundle; import android.widget.Button; public class AddPlayer extends Activity{ ArrayList list1 = new ArrayList(); ArrayAdapter adapter1; EditText playerIn; Button button1; ListView playerlist3; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.playerinput); playerIn = (EditText) findViewById(R.id.inputname); playerlist3=(ListView) findViewById(R.id.selectview); button1 = (Button) findViewById(R.id.addbutton); adapter1 = new ArrayAdapter(this, android.R.layout.simple_list_item_1, list1); View.OnClickListener listener5 = new View.OnClickListener() { @Override public void onClick(View v) { String name = playerIn.getText().toString(); playerlist3.add(name); adapter1.notifyDataSetChanged(); } }; button1.setOnClickListener(listener5); } }

playerinput.xml
