Question

我有一个带适配器的listview但是当我点击listview时我没有回复。我已尝试过其他帖子的一些回复，例如setOnItemClickListener Not Working In Custom Listview或Android - setOnItemClickListener event of ListView not working in Fragment，但我无法解决问题。我告诉你我的代码。

首先，mainActivity

public class MyListActivity extends ListActivity {

private MainView view;

public void onCreate(Bundle icicle) {
super.onCreate(icicle);

   Bundle b=this.getIntent().getExtras();
   String[] array=b.getStringArray("listaEventos");

   /**A continuación, generamos los distintos valores que ocuparán el LinearLayout, concretamente
    * las categorías de los eventos.
    */

   String[] values = new String[] { "Actividades vacacionales", "Aire libre y excursiones", "Cine",
    "Conferencias y otros", "Congresos y jornadas", "Cursos y talleres", "Deporte", "Escénicas",
    "Exposiciones", "Ferias", "Fiestas y festivales", "Música", "Viajes", "Otras" };

   /**
    * Llamamos al adapter personalizado para mostrar la vista.
    */
   MyListCategoryArrayAdapter adapter = new MyListCategoryArrayAdapter(this, values, array);
   setListAdapter(adapter);

   //Log.d("YA SE HA ADAPTADO", "YA SE HA ADAPTADO");

   view = (MainView)View.inflate(this, R.layout.all_products, null);
   //view.setViewListener(viewListener);
   setContentView(view);

}

然后，adapterActivity：

public class MyListCategoryArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
private final String[] listanumber2;

public MyListCategoryArrayAdapter(Context context, String[] values, String[]   listanumber) {
super(context, R.layout.rowlayout, values);
this.context = context;
this.values = values;
this.listanumber2 = listanumber;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

  if(convertView==null){

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.rowlayout, parent, false);
  }
        ImageView imageView = (ImageView) convertView.findViewById(R.id.icon);
        TextView textView = (TextView) convertView.findViewById(R.id.label);
        TextView textView2 = (TextView) convertView.findViewById(R.id.number);

        textView.setText(values[position]);

        String categoria = values[position];

        if (categoria.startsWith("Actividades vacacionales")) {
            imageView.setImageResource(R.drawable.pic_vacaciones);
            textView2.setText(listanumber2[0].trim()+" eventos");
        }
        if (categoria.startsWith("Aire libre y excursiones")) {
            imageView.setImageResource(R.drawable.pic_aire_libre_excursiones);
            textView2.setText(listanumber2[1].trim()+" eventos");
        }
        if (categoria.startsWith("Cine")) {
            imageView.setImageResource(R.drawable.pic_cine);
            textView2.setText(listanumber2[2].trim()+" eventos");
        }
        if (categoria.startsWith("Conferencias y otros")) {
            imageView.setImageResource(R.drawable.pic_conferencias);
            textView2.setText(listanumber2[3].trim()+" eventos");
        }
        if (categoria.startsWith("Congresos y jornadas")) {
            imageView.setImageResource(R.drawable.pic_congresos_jornadas);
            textView2.setText(listanumber2[4].trim()+" eventos");
        }
        if (categoria.startsWith("Cursos y talleres")) {
            imageView.setImageResource(R.drawable.pic_curso_taller);
            textView2.setText(listanumber2[5].trim()+" eventos");
        }
        if (categoria.startsWith("Deporte")) {
            imageView.setImageResource(R.drawable.pic_deporte);
            textView2.setText(listanumber2[6].trim()+" eventos");
        }
        if (categoria.startsWith("Escénicas")) {
            imageView.setImageResource(R.drawable.pic_escenicas);
            textView2.setText(listanumber2[7].trim()+" eventos");
        }
        if (categoria.startsWith("Exposiciones")) {
            imageView.setImageResource(R.drawable.pic_exposiciones);
            textView2.setText(listanumber2[8].trim()+" eventos");
        }
        if (categoria.startsWith("Ferias")) {
            imageView.setImageResource(R.drawable.pic_ferias);
            textView2.setText(listanumber2[9].trim()+" eventos");
        }
        if (categoria.startsWith("Fiestas y festivales")) {
            imageView.setImageResource(R.drawable.pic_fiesta_festival);
            textView2.setText(listanumber2[10].trim()+" eventos");
        }
        if (categoria.startsWith("Música")) {
            imageView.setImageResource(R.drawable.pic_musica);
            textView2.setText(listanumber2[11].trim()+" eventos");
        }
        if (categoria.startsWith("Viajes")) {
            imageView.setImageResource(R.drawable.pic_viajes);
            textView2.setText(listanumber2[12].trim()+" eventos");
        }
        if (categoria.startsWith("Otras")) {
            imageView.setImageResource(R.drawable.pic_otros);
            textView2.setText(listanumber2[13].trim()+" eventos");
        }
  return convertView;



}

然后，我用来捕获用户交互的视图：

    /**
 * Find our references to the objects in the xml layout
 */
@Override
protected void onFinishInflate() {
    super.onFinishInflate();

    final ListView list = (ListView)findViewById(android.R.id.list);
    list.setItemsCanFocus(false);
    list.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1,
                int position, long arg3) {
            Log.d("HERE IT DOES NOT ENTER", "HERE IT DOES NOT ENTER");
        }
    });


  final Button button0 = (Button)findViewById(R.id.button1);
    button0.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Log.d("Boton0000", "Boton0000");

        }
    });
  final Button button1 = (Button)findViewById(R.id.button2);

  button1.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Log.d("Boton1111", "Boton1111");

        }
  }); 

    final Button button2 = (Button)findViewById(R.id.button3);
    button2.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Log.d("Boton2222", "Boton2222");

        }
    }); 

    final Button button3 = (Button)findViewById(R.id.button4);
    button3.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Log.d("Boton3333", "Boton3333");

        }
    }); 
}

最后，我为listView和列表的每一行显示.xml：

all.products.xml

 </RelativeLayout>

有人可以帮帮我吗？

提前致谢。

问候。

Answer 1

您应该在扩展的ListActivity中覆盖onListItemClick。

Answer 2

尝试不要使用ListView。在android中按名称命名列表视图：

android:id="@+id/my_list"

然后在MainActivity中引用它：

ListView myList = (ListView) findViewById(R.id.my_list);

然后，您可以使用以下内容将myList设置为onItemClickListener

myList.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick (AdapterView<?> parent, View view, int position, long id) {

             // Your code here

    }
});

您无需担心后期充气，因为在ListView充气之前，用户无需点击任何项目。如果不使用ListActivity，您可以摆脱onFinishInflate()以及对其父级的调用，只需将所有点击侦听器放入onCreate()方法中。

另外，另一个提示 - 在onCreate()方法之外声明您的变量，并在onCreate()方法的开头定义它们。这将使它们在整个活动中全球化，因此您不需要final关键字。

Answer 3

在ListActivity中，onContentChanged执行各种操作，包括设置自己的OnItemClickListener。

此OnItemClickListener调用onListItemClick中的ListActivity方法。

因此，为了使其有效，您需要

使用onListItemClick代替设置OnItemClickListener
或设置OnItemClickListener 之后您调用setContentView（可能在onAttachedToWindow，这应该在之后发生，但我没有测试过这个）。

Answer 4

尝试将所有textview的clickable属性设置为false。

机器人：可点击= “假”

Answer 5

在OnItemClickListener

期间将ListView设置为Activity#onCreate()

// inside activity
@Override
protected void onCreate(Bundle savedInstanceState) {
    // calls to super and setcontentview

    listView = (ListView) findViewById(android.R.id.list);
    listView.setOnItemClickListener(new OnItemClickListener() { ......

setOnItemClickListener不起作用
