String playerlist[];

/** Called when the activity is first created. */
@Override

    setContentView(R.layout.screen2);

    // edittext1 or textview1
    txt1 = (EditText) findViewById(R.id.editText1);
     final String ag = txt1.getText().toString();



        //add more items button
    Button more = (Button) findViewById(R.id.button1);
    more.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view){
            if(txt1.getText().length() != 0){
                                     playerList.add(ag);
                            DisplayToast("Current Players" + playerList);

            Intent myIntent = new Intent(view.getContext(),
                    Screen2.class);
             myIntent.putExtra("playerList",playerList);
                startActivity(myIntent);

            }

        }});

Try making your array public static in the activity you are currently in.Then you can directly access that array in next activity.

尝试在您当前所在的活动中将您的数组设为公共静态。然后您可以在下一个活动中直接访问该数组。

As per the scenario you declared in your question,Try this code: say this is your Screen1.class:

根据你在问题中声明的场景，试试这个代码：说这是你的 Screen1.class：

private EditText txt1;
public static ArrayList<String> playerList = new ArrayList<String>();
String playerlist[];

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.screen2);

    // edittext1 or textview1
    txt1 = (EditText) findViewById(R.id.editText1); 

    //add more items button
    Button more = (Button) findViewById(R.id.button1);
    more.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view){

            String ag=txt1.getText().toString().trim();
            if(ag.length() != 0){
                   playerList.add(ag); 
                   txt1.setText(""); // adds text to arraylist and make edittext blank again
            }
        }
    });

    //press Done button to redirect to next activity
    Button done = (Button) findViewById(R.id.done_button);
    done.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view){

            // start new activity
            Intent myIntent = new Intent(view.getContext(),
                    Screen2.class);             
            startActivity(myIntent);

        }
    });
}   

In your Screen2.class,directly access ArrayList like:

在 Screen2.class 中，直接访问 ArrayList，如：

String s=Screen1.playerList.get(index);// this gives your the string saved in arraylist at index given.

I hope,it's clear now!

我希望，现在清楚了！

While onClick the done button just pass the string array to next activity and get the values of array in next screen and display it..You can pass the string array as below

当 onClick 完成按钮只是将字符串数组传递给下一个活动并在下一个屏幕中获取数组的值并显示它..您可以传递字符串数组如下

Intent myIntent = new Intent(view.getContext(),
                Screen2.class);

    myIntent.putExtra("Stringarray",arrayvalue);
    startActvity(myIntent);
   finish();

In Next activity you can get value as

在下一个活动中，您可以获得以下价值

        String[] array=getIntent().getExtras().getStringArray("Stringarray");

Edit:

编辑：

 for(int i=0;i<array.size;i++)
{
    Toast.makeText(this,array[i], Toast.LENGTH_LONG); // here if you have value in array then it will display in toast one by one.
}

I think it may help you...

我想它可以帮助你...
