我试图让一个onClickListener火在微调，但我得到了以下错误：

I'm trying to get an onClickListener to fire on a Spinner, but I get the following error:

java.lang.RuntimeException的是不要叫setOnClickListener了一个AdapterView。你可能想setOnItemClickListener相反，

Java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead,"

我敢肯定，我想打电话给onClickListener和NOT onItemClickListener。我发现问别人对堆栈溢出的问题，的 有没有办法使用setOnClickListener与Android的微调？

I'm sure I want to call onClickListener and NOT onItemClickListener. I found a question asked by someone else on Stack Overflow, Is there a way to use setOnClickListener with an Android Spinner?

答案提到有：

您必须设置点击   听众底层视图   （通常是一个id为TextView的：   android.R.id.text1）微调的。至   这样做的：

You will have to set the Click listener on the underlying view (normally a TextView with id: android.R.id.text1) of the spinner. To do so:

创建自定义微调在   构造器（带属性）创建   微调通过提供布局   android.R.layout.simple_spinner_item   做一个findViewById（android.R.id.text1）   得到的TextView现在设置   onClickListener到的TextView

Create a custom Spinner In the constructor (with attributes) create the spinner by supplying the layout android.R.layout.simple_spinner_item Do a findViewById(android.R.id.text1) to get the TextView Now set the onClickListener to the TextView

我试图回答说有，但似乎并没有工作。我得到一个空指针的TextView后，我做的findViewById（）。

I have tried the answer noted there, but it doesn't seem to work. I get a null pointer to the TextView after I do the findViewById().

这是我在做什么：

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.layoutspinner,dataArray);

spinner.setAdapter(adapter);

TextView SpinnerText = (TextView)findViewById(R.id.spinnerText);
if (SpinnerText == null) {
    System.out.println("Not found");
}
else {
    SpinnerText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            //Do something
        }
    });
}

文件layoutspinner.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
                  android:id="@+id/spinnerText"
                  android:singleLine ="true"
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  android:textSize="6pt"
                  android:gravity="right"/>

我是什么做错了吗？

What am I doing wrong?

我是新来的堆叠式和NBSP;溢出，我没有发现任何方式发布一个aditional的问题，给其他线程（或评论，因为我有一点代表），所以我开始了一个新的问题

I'm new to StackOverflow, I didn't find any way to post an aditional question to the other thread (or comment since I have to little rep) so I started a new question.

每recomendation我尝试这样做：

Per recomendation I tried this:

int a = spinnerMes.getCount();
int b = spinnerMes.getChildCount();
System.out.println("Count = " + a);
System.out.println("ChildCount = " + b);
for (int i = 0; i < b; i++) {
    View v = spinnerMes.getChildAt(i);
    if (v == null) {
        System.out.println("View not found");
    }
    else {
        v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Click code
            }
        });
    }
}

不过 LogCat中未显示出有希望的结果。

But LogCat isn't showing promising results.

10-14 16:09:08.127: INFO/System.out(3116): Count = 7
10-14 16:09:08.127: INFO/System.out(3116): ChildCount = 0

我已经在API级别7和8相同的结果测试这一点。

I have tested this on API levels 7 and 8 with the same results.

推荐答案

下面的工作你想要的，但它并不理想。

The following works how you want it, but it is not ideal.

public class Tester extends Activity {

    String[] vals = { "here", "are", "some", "values" };
    Spinner spinner;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        spinner = (Spinner) findViewById(R.id.spin);
        ArrayAdapter<String> ad = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, vals);
        spinner.setAdapter(ad);
        Log.i("", "" + spinner.getChildCount());
        Timer t = new Timer();
        t.schedule(new TimerTask() {

            @Override
            public void run() {
                int a = spinner.getCount();
                int b = spinner.getChildCount();
                System.out.println("Count =" + a);
                System.out.println("ChildCount =" + b);
                for (int i = 0; i < b; i++) {
                    View v = spinner.getChildAt(i);
                    if (v == null) {
                        System.out.println("View not found");
                    } else {
                        v.setOnClickListener(new View.OnClickListener() {

                            @Override
                            public void onClick(View v) {
                                        Log.i("","click");
                                        }
                        });
                    }
                }
            }
        }, 500);
    }
}

让我知道你到底有需要微调的行为，我们可以制定出一个更好的解决方案。

Let me know exactly how you need the spinner to behave, and we can work out a better solution.
