单击ListView的列表项不响应

Question

你好.通过下面列出的代码,我的listview项目不会以任何方式响应点击.有人可以帮帮我吗？提前致谢.

public class ListaActivity extends Activity {

    public final static String EXTRA_MESSAGE = "com.example.provacomunicazione.MESSAGE";
    @Override
    public void onCreate(Bundle savedInstanceState)  {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.lsta);
        Resources res = getResources();
        String[] Authors = res.getStringArray(R.array.Lista_Nomi_E_Cognomi_Autori);
        ArrayList<String> Autori = new ArrayList<String>();
        for (String temp:Authors) {
            Autori.add(temp);
        }
        Collections.sort(Autori);
        ArrayList<String> AutoriLetteraSelezionata = new ArrayList<String>();
        for (String temp:Autori) {
            if (temp.charAt(0)=='A') {
                AutoriLetteraSelezionata.add(temp);
            }
        }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.textviewitem, AutoriLetteraSelezionata);
        ListView listView = (ListView) findViewById(R.id.listView1);
        listView.setAdapter(adapter);
        listView.setClickable(true);
        listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

            CharSequence autore = "("+((TextView)view).getText()+")";

            Intent i = new Intent(ListaActivity.this, SecondaryActivity.class);
            i.putExtra(EXTRA_MESSAGE, autore);
            startActivity(i);  
        });
    }
}    

}}

您应该在项目列表视图(TextView,ImageView等)中定义所有子对象:

android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"

对于根项RelativeLayout/LinearLayout等,定义:

android:clickable="false"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"

如果您不定义它们,它们将"捕获"click事件.如果您有自定义listView适配器,只需检查您是否覆盖:

@Override
public boolean isEnabled(int position)
{
    return true;
}
