android - 事件 setOnItemClickListener 在我的列表中不起作用

Question

我在列表 lista 中调用事件 OnItemClickListener，但它不起作用，Toast 未显示。

在我的代码下面 fragment1.java

public class Fragment1 extends Fragment {
    Switch mySwitch;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){      
        //nome dos reles
        String[] atividades = new String[]{"lampada","tomada quarto","tomada cozinha","geladeira"};

        //interface
        View view=inflater.inflate(R.layout.layout_acionamento, container,false);       

        //lista
        ListView lista = (ListView)view.findViewById(R.id.mylistView);          

        //botão acionar
        Button button = (Button) view.findViewById(R.id.buttonAcionar);

        //adaptador de string para reles
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), R.layout.modelo_lista_reles,atividades);
        lista.setAdapter(adapter);

        //evento do botão acionar
        button.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(getActivity(), "CUBANAJARRA", getId()).show();
            }
        });

        lista.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // TODO Auto-generated method stub
                Toast.makeText(getActivity(), "CUBANAJARRA_lista", getId()).show();
            }
        });

        return(view);
    }
}

我的 modelo_lista_rele.xml 代码(我用它来创建带开关的列表):

<?xml version="1.0" encoding="utf-8"?>
<Switch xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentEnd="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"    
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:focusable="false"
    android:focusableInTouchMode="false"/>

我的 layout_acionamento.xml 代码(用于我在 fragment 中返回的 View ):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ListView
        android:id="@+id/mylistView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/buttonAcionar"
        android:layout_alignParentTop="true"
        android:clickable="true" >
    </ListView>

    <Button
        android:id="@+id/buttonAcionar"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="Acionar" />

</RelativeLayout>

Answer 1

Toast.makeText(getActivity(), "CUBANAJARRA", getId()).show();

第三个参数是长度不是id。尝试使用 Toast.LENGTH_LONG 或 Toast.LENGTH_SHORT 代替:

Toast.makeText(getActivity(), "CUBANAJARRA", Toast.LENGTH_LONG).show();
