推荐答案

您只需做到以下几点：prepare你的XML是这样的：

You just do the following : Prepare your xml like this :

<?xml version="1.0" encoding="utf-8"?>

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_toLeftOf="@+id/addItem"
    android:hint="Add a new item to List View" />

<Button
    android:id="@+id/addItem"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:text="Add" />

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/editText" >
</ListView>

活动看起来像下面这样：

Activity looks like following :

public class MainActivity extends Activity {
    EditText editText;
    Button addButton;
    ListView listView;
    ArrayList<String> listItems;
    ArrayAdapter<String> adapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText = (EditText) findViewById(R.id.editText);
        addButton = (Button) findViewById(R.id.addItem);
        listView = (ListView) findViewById(R.id.listView);
        listItems = new ArrayList<String>();
        listItems.add("First Item - added on Activity Create");
        adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, listItems);
        listView.setAdapter(adapter);
        addButton.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                listItems.add(editText.getText().toString());
                adapter.notifyDataSetChanged();
            }
        });
        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position,
                    long id) {
                Toast.makeText(MainActivity.this, "Clicked", Toast.LENGTH_LONG)
                        .show();
            }
        });
    }
}
