onItemClick ListView中无法正常工作 [英] onItemClick in ListView doesn't work

问题描述

我无法得到吐司消息为 onItemClick 永远不会被调用。登录猫不显示任何错误。请看看我的code和纠正我，如果我错了任何地方。我已经使用阵列适配器。

 公共类开放式扩展ListActivity {
    DbAdapter MDB =新DbAdapter（本）;    @覆盖
    保护无效的onDestroy（）{
        // TODO自动生成方法存根
        mDb.close（）;
        super.onDestroy（）;
    }    / **当第一次创建活动调用。 * /
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.open）;        ListView控件的listContent =（ListView控件）findViewById（android.R.id.list）;        mDb.open（）;
        光标光标= mDb.fetchAllPrograms（）;
        startManagingCursor（光标）;        的String [] =由新的String [] {} DbAdapter.KEY_TITLE;
        INT []为= INT新[] {} R.id.textViewName;        SimpleCursorAdapter的CursorAdapter =新SimpleCursorAdapter（这一点，
    R.layout.row，光标，从，到）;
        listContent.setAdapter（CursorAdapter的）;        // ONCLICK的ListView使用setListener
        listContent.setTextFilterEnabled（真）;
        的listContent = getListView（）;
            listContent.setOnItemClickListener（新OnItemClickListener（）{
                公共无效onItemClick（适配器视图＆LT;＆GT;母公司，查看    看来，INT位置，长的id）{
                    Toast.makeText（getApplicationContext（），
   加工！，
                    Toast.LENGTH_LONG）.show（）;
                }
            }）;    }
}
 

Row.xml如下：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;的TextView
    机器人：ID =@ + ID / textViewName
    的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：layout_marginTop =10dp
     机器人：layout_marginBottom =10dp
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：TEXTSIZE =25sp
    机器人：文字颜色=＃0000FF
    机器人：textIsSelectable =真
     /＆GT;
 

解决方案

我跑成一个类似的问题。不仅是我的onItemClick方法被忽略了，也是我的列表选择不工作（的android：listSelector ）

原来这是的android：textIsSelectable 我的TextView行元素属性。尝试将它设置为假。

I am unable to get Toast message as onItemClick is never called. Log-cat doesn't show any error. Please check out my code and correct me, if I am going wrong anywhere. I have used array adapter.

public class Open extends ListActivity {
    DbAdapter mDb = new DbAdapter(this);

    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        mDb.close();
        super.onDestroy();
    }

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.open);

        ListView listContent = (ListView) findViewById(android.R.id.list);

        mDb.open();
        Cursor cursor =mDb.fetchAllPrograms();
        startManagingCursor(cursor);

        String[] from = new String[] { DbAdapter.KEY_TITLE };
        int[] to = new int[] { R.id.textViewName };

        SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, 
    R.layout.row, cursor, from, to);
        listContent.setAdapter(cursorAdapter);

        //Onclick ListView setlistener
        listContent.setTextFilterEnabled(true);
        listContent=getListView();


            listContent.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View 

    view,int position, long id) {
                    Toast.makeText(getApplicationContext(),
   "Working!", 
                    Toast.LENGTH_LONG).show();    
                }
            });

    }
}

Row.xml is as follows:

<?xml version="1.0" encoding="utf-8"?>
<TextView
    android:id="@+id/textViewName"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_marginTop="10dp"
     android:layout_marginBottom="10dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="25sp"
    android:textColor="#0000FF"
    android:textIsSelectable="true"
     />

解决方案

I was running into a similar issue. Not only was my onItemClick method being ignored, but also my List Selector wasn't working (android:listSelector.)

Turns out it was the android:textIsSelectable attribute on my TextView row elements. Try setting it to false.
