单击列表视图后显示带有按钮和内部编辑文本的迷你表单

Question

我想在点击列表视图后显示一个带有按钮和 Edittext 的迷你表单。

这是来自互联网的代码。在列表视图项目中长按后，如何显示带有按钮和文本框的简单表单。

我正在使用 Android Studio。

public class sample extends Activity{

    SimpleAdapter simpleAdpt;
    private EditText pass;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sample);
        initList();

        // We get the ListView component from the layout
        ListView lv = (ListView) findViewById(R.id.listView);

        simpleAdpt = new SimpleAdapter(this, planetsList, android.R.layout.simple_list_item_1, new String[] {"planet"}, new int[] {android.R.id.text1});

        lv.setAdapter(simpleAdpt);
 List<Map<String, String>> planetsList = new ArrayList<Map<String,String>>();

    private void initList() {
        planetsList.add(createPlanet("planet", "Mercury"));
        planetsList.add(createPlanet("planet", "Venus"));
        planetsList.add(createPlanet("planet", "Mars"));
        planetsList.add(createPlanet("planet", "Jupiter"));
        planetsList.add(createPlanet("planet", "Saturn"));
        planetsList.add(createPlanet("planet", "Uranus"));
        planetsList.add(createPlanet("planet", "Neptune"));
    }

    private HashMap<String, String> createPlanet(String key, String name) {
        HashMap<String, String> planet = new HashMap<String, String>();
        planet.put(key, name);

        return planet;
    }

您可能希望按如下方式实现 ItemLongClickListener：

lv.setOnItemLongClickListener(new OnItemLongClickListener() {

        public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                int pos, long id) {
            // TODO Auto-generated method stub

            //do what you want to do.
            //If you want to delete that entry.
            lv.remove(arg2);//where arg2 is position of item you click
            myAdapter.notifyDataSetChanged();

            return true;
        }
    });

现在，如果您希望 textBox 和按钮显示为 AlertDialog 或者您想导航到另一个页面，这就是问题所在。

如果它应该是一个带有文本框的弹出窗口

AlertDialog.Builder alert = new AlertDialog.Builder(this);

alert.setTitle("Title");
alert.setMessage("Message");

// Set an EditText view to get user input 
final EditText input = new EditText(this);
alert.setView(input);

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {

  // Do something with value!
  }
});

alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int whichButton) {
    // Canceled.
  }
});

alert.show();

如果它应该导航到一个页面

Intent intent = new Intent(ActivityA.this, ActivityB.class);
startActivity(intent);
