Question

所以即时尝试为我的ListView设置一个setOnClickListener，但由于某些原因导致我的程序崩溃，当我尝试..我很新的编程所以当涉及到故障排除我真的不能做任何可悲的事情:(我的代码在下面，所以任何关于可能出错的想法都会非常有用

public class HomePageActivity extends Activity {
    //ListView that holds the items
    ListView lstTest;

    //Array Adapter that holds the ArrayList and displays the items on the ListView
    AlertsAdapter arrayAdapter;

    //List that hosts the items
    ArrayList&lt;Alerts&gt; alrts = null;

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.homepage);

        //Initialize the ListView
        lstTest = (ListView)findViewById(R.id.lstText);

        //Initialize the ArrayList
        alrts = new ArrayList&lt;Alerts&gt;();

        //Initialize the array adapter
        arrayAdapter = new AlertsAdapter(HomePageActivity.this, R.layout.listitems,alrts);

        //Set the above adapter as the adapter of choice for our list
        lstTest.setAdapter(arrayAdapter);

        lstTest.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(
                HomePageActivity.this,
                PromotionActivity.class
                );
                startActivity(intent);
            }
        });

        //... ... ...

    }
}

任何想法？我卡住了:(

我看到它说我可能想要setOnItemClickListener，这本来就是我编码的，但是因为eclipse告诉我我的代码错了所以它不会工作

Answer 1

您需要使用setOnItemClickListener()

然后new android.widget.AdapterView.OnItemClickListener()

不是new View.OnItemClickListener()

Answer 2

请尝试使用setOnClickListener

，而不是使用setOnItemClickListener

Answer 3

如果使用Butterknife，请检查您是否没有适用于AdapterView下行的OnClick注释（Spinner，ListView等）

@OnClick(R.id.spinner_id)

调用ButterKnife.inject(this, view);将抛出异常

Caused by: java.lang.RuntimeException: Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead

Answer 4

首先在您使用listview的主要活动中设置值：

new android.widget.AdapterView.OnItemClickListener()

代替listview的适配器：

  new AdapterView.OnItemClickListener()

所以最后它看起来像：

this.listView.setItemsCanFocus(false);
this.listView.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(android.widget.AdapterView<?> parent, View view, int position, long id) {

 }

当您使用任何自定义视图填充listview中的数据时。

然后在父布局的主Activity file.xml中{listview is there}，设置此选项：

    android:descendantFocusability="blocksDescendants"

如果您在listview中使用任何按钮/ textview，请在该textview /按钮上设置此属性：

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

对于列表视图中的滚动选项，只需在活动中添加以下内容：

 listView=(ListView)findViewById(R.id.container);
 listView.setNestedScrollingEnabled(true);

据我所知，我正在给予答案，我希望它会有所帮助，如果有人发现了一些更正或有帮助，我们欢迎他们。

Answer 5

在我的情况下，我尝试为转盘添加onClickListener，但我遇到了同样的问题。我已经创建了使用触摸侦听器的解决方法。有时我们需要它用于hideKeyBoard或发送一些analyticEvent：

someSpinner.setOnTouchListener { _, event ->  onTouchSomeSpinner(event)}

fun onTouchSomeSpinner(event: MotionEvent): Boolean {
        if(event.action == MotionEvent.ACTION_UP) {
            view.hideKeyBoard()
            view.analyticsEvent()
            ...
        }
        return false
}

ListView的setOnClickListener无法正常工作
