用不同的动作多可点击的项目在ListFragment从SQLite的执行 [英] Multiple clickable items with different actions to perform in ListFragment from SQLite
本文介绍了用不同的动作多可点击的项目在ListFragment从SQLite的执行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是个初学者。
我有一个ListFragment即列表中的每个元素都包含三个TextView的和两个不同的按钮。从SQLite数据库中读取数据。事情是这样的：
I'm a beginner. I've a ListFragment where every element in the list contains three TextView and two different Buttons. Reading data from SQLite Database. Something like this:
ListFragment
--------------------
[Person Name]
[Person Phone]
[Person e-mail]
[Button 1][Button 2]
--------------------
[Person Name]
[Person Phone]
[Person e-mail]
[Button 1][Button 2]
--------------------
... (and so on) ...
当按钮1将拨打电话和2键会发送电子邮件到人。
细节，这些按钮是可以点击的ImageView。
where the button 1 will make a call and the 2 button will send an email to person. detail, these buttons are clickable ImageView.
数据库已在$ P $填充页。
the Database is already pre-populated.
我iniciate我的code是这样的：
I iniciate my code like this:
@SuppressWarnings("deprecation")
public class Fragment01person extends ListFragment {
SQLiteDatabase dataBase = null;
Cursor crs;
SimpleCursorAdapter dataAdapter;
ListView listView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment01person, container,false);
dataBase = getActivity().openOrCreateDatabase("DBperson.db",
android.content.Context.MODE_PRIVATE, null);
crs = dataBase.rawQuery("SELECT * FROM person", null);
String[] columns = new String[] {
"person_name",
"person_phone",
"person_email"
};
// the XML defined views which the data will be bound to
int[] to = new int[] {
R.id.text01person,
R.id.text02person,
R.id.text03person
};
// create the adapter using the cursor pointing to the desired data
//as well as the layout information
dataAdapter = new SimpleCursorAdapter(
getActivity(), R.layout.fragment01itemlist,
crs,
columns,
to);
listView = (ListView) rootView.findViewById(android.R.id.list);
View v = new View(getActivity());
listView.addHeaderView(v);
listView.addFooterView(v);
// Assign adapter to ListView
listView.setAdapter(dataAdapter);
rootView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT ));
return rootView;
}
public void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
Cursor cursorLocal = (Cursor) l.getItemAtPosition(position);
String nameperson = cursorLocal.getString(cursorLocal.getColumnIndex("person_name"));
String endperson = cursorLocal.getString(cursorLocal.getColumnIndex("person_endereco"));
String phoneperson = cursorLocal.getString(cursorLocal.getColumnIndex("person_phone"));
String emailperson = cursorLocal.getString(cursorLocal.getColumnIndex("person_email"));
showMessage("test",nameperson+" "+endperson+" "+phoneperson+" "+emailperson);
}
public void showMessage (String title, String text){
AlertDialog.Builder message = new AlertDialog.Builder(getActivity());
message.setTitle(title);
message.setMessage(text);
message.setNeutralButton("Ok", null);
message.show();
}
}
这是我的ITEMLIST XML（fragment01itemlist.xml）：
this is my itemlist xml (fragment01itemlist.xml):
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/itemlistPerson"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:descendantFocusability="beforeDescendants">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="15dp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:paddingRight="15dp"
android:descendantFocusability="afterDescendants">
<TextView
android:id="@+id/text01person"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/blue_light2"
android:textSize="18sp"
android:text= "test"
android:textStyle="bold|italic"
/>
<TextView
android:id="@+id/text02person"
android:layout_width="wrap_content"
android:text= "test"
android:layout_height="wrap_content"
/>
<TextView
android:id="@+id/text03person"
android:layout_width="wrap_content"
android:text= "test"
android:layout_height="wrap_content"
android:textStyle="italic"
/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/imgPhone"
android:layout_width="?android:attr/listPreferredItemHeight"
android:layout_height="fill_parent"
android:src="@drawable/ic_action_call_tc_01"
android:scaleType="center"
android:clickable="true"
android:focusable="false"
android:focusableInTouchMode="true"
/>
<ImageView
android:id="@+id/imgEmail"
android:layout_width="?android:attr/listPreferredItemHeight"
android:layout_height="fill_parent"
android:src="@drawable/ic_action_new_email_tc"
android:scaleType="center"
android:clickable="true"
android:focusable="false"
android:focusableInTouchMode="true"
/>
</LinearLayout>
</LinearLayout>
</FrameLayout>
这是我的ListView XML（fragment01person.xml）：
this is my listview xml (fragment01person.xml):
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="@color/pink_very_light"
android:cacheColorHint="@android:color/transparent"
android:divider="@null"
android:dividerHeight="10dp"
android:footerDividersEnabled="true"
android:headerDividersEnabled="true"
android:listSelector="@android:color/transparent" >
</ListView>
</RelativeLayout>
我可以显示列表。
但我不知道如何实现的按钮！
I can display the list. but I don't know how to implement the buttons!
我读过的各种材料，但没有工作。
I've read various materials, but none works.
请任何人都可以在这方面帮助？
推荐答案
有关在列表行做多clickables你必须包含如下code代表的意见/在XML按钮：
For making the multiple clickables in your list row you have to include the below given code for the views/buttons in the XML:
android:clickable="true"
android:focusable="false"
android:focusableInTouchMode="true"
和做操作单列你需要使用而不是使用SimpleCursorAdapter自定义适配器，这里的例子去
and for doing operation for single row you need to use custom adapters instead using SimpleCursorAdapter, here the example goes
public class CustomListAdapter extends BaseAdapter
{
private Context mContext;
String[] cursor;
public SMSListAdapter(Context context,String[] cur)
{
super();
mContext=context;
cursor=cur;
}
public int getCount()
{
// return the number of records in cursor
return cursor.length;
}
// getView method is called for each item of ListView
public View getView(int position, View view, ViewGroup parent)
{
// inflate the layout for each item of listView
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.listview_each_item, null);
// get the reference of textViews
TextView textViewConatctNumber=(TextView)view.findViewById(R.id.textViewSMSSender);
TextView textViewSMSBody=(TextView)view.findViewById(R.id.textViewMessageBody);
Button bt1=(Button)view.findViewById(R.id.btn1);
bt1.setOnClickListner(new OnClickListener() {
@Override
public void onClick(View view) {
}
});
// Set the Sender number and smsBody to respective TextViews
textViewConatctNumber.setText(senderNumber);
textViewSMSBody.setText(smsBody);
return view;
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
}
