动态微调 - 无法点击下拉列表 - Android

Question

我在页面中包含动态微调。 单击微调器时，它将下拉图像和文本的选择。 问题是，当我想选择下面的值之一，如“类别B”，它不能点击。 为什么？我的代码有任何问题？

真的需要某人的帮助。

感谢

* Category.java ***

private Spinner iconSpinner; 
String[] iconArrays = {"Category A", "Category B"}; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_categorydetails); 
    addListenerOnSpinnerItemSelection();

public void addListenerOnSpinnerItemSelection(){ 

    iconSpinner = (Spinner) findViewById(R.id.iconSpinner); 
    iconSpinner.setAdapter(new MyCustomAdapter(this, R.layout.icon_row, iconArrays)); 
    iconSpinner.setOnItemSelectedListener(this); 
} 



public class MyCustomAdapter extends ArrayAdapter<String>{

    String[] objects) { 
     super(context, textViewResourceId, objects); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public View getDropDownView(int position, View convertView, 
    ViewGroup parent) {

     return getCustomView(position, convertView, parent);

     //LayoutInflater inflater = (LayoutInflater) CategoryDetailsActivity.this.getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     LayoutInflater inflater = getLayoutInflater(); 
     View row=inflater.inflate(R.layout.icon_row, parent, false); 
     TextView label=(TextView)row.findViewById(R.id.iconLabel);

     ImageView icon=(ImageView)row.findViewById(R.id.icon); 

     if (iconArrays[position]=="Category A"){ 
      icon.setImageResource(R.drawable.ic_catA); 
     }

      Toast.LENGTH_SHORT).show();

@Override

    // TODO Auto-generated method stub 

} 

* icon_row.xml ***

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="50dip" 
    android:orientation="horizontal"> 
    <ImageView 
    android:id="@+id/icon" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:contentDescription="@string/stringIcon" 
    android:layout_margin="10dip"/> 
    <TextView 
    android:id="@+id/iconLabel" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:textIsSelectable="true" 
    android:layout_margin="10dip"/> 
</LinearLayout> 

Answer 1

icon_row.xml

删除机器人：textIsSelectable =从TextView的 “真”

Answer 2

iconSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { 
    @Override 
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
     // your code here 
    } 

    @Override 
    public void onNothingSelected(AdapterView<?> parentView) { 
     // your code here 
    } 

}); 

难道üTR你呢？

EDIT

尝试此方法，

activity_main.xml中

<Spinner 
      android:id="@+id/spinner" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 

      android:entries="@array/list" 
      android:prompt="@string/select_menu" /> 

的strings.xml

<string name="select_menu">Select Category</string> 

    <string-array name="list"> 
     <item >Category A</item> 
     <item >Category B</item> 

    </string-array> 

的Java文件

iconspinner = (Spinner) findViewById(R.id.spinner); 

    ArrayAdapter<CharSequence> cat_list = ArrayAdapter.createFromResource(
      this, R.array.list, android.R.layout.simple_spinner_item); 

    cat_list.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    iconspinner.setAdapter(cat_list); 

    iconspinner.setOnItemSelectedListener(new OnItemSelectedListener() { 

     @Override 
     public void onItemSelected(AdapterView<?> arg0, View arg1, 
       int arg2, long arg3) { 
      // TODO Auto-generated method stub 
      Toast.makeText(getApplicationContext(), 
        iconspinner.getSelectedItem().toString(), 
        Toast.LENGTH_LONG).show(); 
     } 

     @Override 
     public void onNothingSelected(AdapterView<?> arg0) { 
      // TODO Auto-generated method stub 

     } 

    }); 

我试图这样做，它是工作的罚款。只是检查
