我有一个ListView，我想根据点击的值运行一个函数ListView，现在我只想知道如何获取和烤我试图做的值，但不知道正确的代码......请检查我的代码。

public class SubCategory extends AppCompatActivity implements View.OnClickListener {

private ListView listView;
String buttonType;
ArrayAdapter adapter;

static final String[] FRUITS = new String[] { "Apple", "Avocado", "Banana"};
static final String[] NAMES = new String[] { "Sachin", "Brett", "Shane", "Zaheer"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sub_category);



    Bundle bundle = getIntent().getExtras();
    if(bundle != null) {
        buttonType = bundle.getString("BUTTON_CLICKED");
    }
    if(buttonType != null && buttonType.equals("A")) {
        adapter = new ArrayAdapter<String>(this, R.layout.activity_listview, FRUITS);
    } else if(buttonType != null && buttonType.equals("B")) {
        adapter = new ArrayAdapter<String>(this, R.layout.activity_listview, NAMES);
    }
    listView = (ListView)findViewById(R.id.listview);
    listView.setAdapter(adapter);
}

     public void getList() {

        Toast.makeText(listView.getContext(), Toast.LENGTH_LONG).show();

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.listview:
                getList();
                break;
    }
}
}

试试这个

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      String value="";
      if(!TextUtils.isEmpty(buttonType) && buttonType.equals("A")) {
          value=FRUITS[position];
       } else if(!TextUtils.isEmpty(buttonType) && buttonType.equals("B")) {
          value=NAMES[position];
       }
     // you can get value in "value"
       showToast(value);
    }
});
public void showToast(String value) {

    Toast.makeText(this,value, Toast.LENGTH_LONG).show();

}
