使用复选框过滤联系人并获取电话号码 [英] using checkbox to filter contacts and get phone number
问题描述
我正在开发一款与所有 Android 手机上的默认短信应用类似的应用.我的问题是选择多个用户来发送 SMS 消息.到目前为止，我所做的将我的联系人存储为带有复选框的列表视图项目.现在我只需要从选定的联系人中获取电话号码.
I am working on an app that works similar to the default text messaging app on all Android phones. My problem is selecting more than one user to send an SMS message to. What I have done so far is stored my contacts as listview items with check boxes. Now I just need to get the phone numbers from the selected contacts.
所以我在做的事情上遇到了麻烦.1)从我的列表视图中显示的联系人中提取电话号码2)在新活动的文本视图中显示该数字
So what I am having trouble on doing. 1) Pulling a phone number from the contacts displayed in my listview 2)displaying that number in a textview in a new activity
抱歉，如果我的代码难以理解，请询问您是否需要澄清.
Sorry if my code is difficult to understand, please ask if you need clerification.
这是显示列表视图的 XML，称为 contact_manager.xml:
This is the XML in which the listview is shown, called contact_manager.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="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/contactList"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="@+id/showInvisible"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/showInvisible" />
</LinearLayout>
这是我的 Activity，它把所有东西都调用在一起.
This is my Activity that calls everything together.
public final class ContactManager extends Activity {
public static final String TAG = "ContactManager";
private ListView mContactList;
private boolean mShowInvisible;
private Button mShowInvisibleControl;
/**
* Called when the activity is first created. Responsible for initializing
* the UI.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
Log.v(TAG, "Activity State: onCreate()");
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_manager);
// Obtain handles to UI objects
mContactList = (ListView) findViewById(R.id.contactList);
mShowInvisibleControl = (Button) findViewById(R.id.showInvisible);
// Initialize class properties
mShowInvisible = false;
// mShowInvisibleControl.setChecked(mShowInvisible);
mShowInvisibleControl.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
}
});
populateContactList();
}
/**
* Populate the contact list based on account currently selected in the
* account spinner.
*/
private void populateContactList() {
// Build adapter with contact entries
Cursor cursor = getContacts();
String[] fields = new String[] { ContactsContract.Data.DISPLAY_NAME };
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
R.layout.contact_entry, cursor, fields,
new int[] { R.id.contactEntryText });
mContactList.setAdapter(adapter);
}
/**
* Obtains the contact list for the currently selected account.
*
* @return A cursor for for accessing the contact list.
*/
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ (mShowInvisible ? "0" : "1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}
contact_entry.xml
contact_entry.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<CheckBox

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/contactEntryText" />

这是我的invite_text.xml 这实际上是我想要输入数字的文本视图，以便我可以发送大量文本消息.
This is my invite_text.xml This is actually the text view i want to input the numbers into so i can send a mass text message.

推荐答案
我没有看过你的代码，但这里是对我有用的机制:
I have not looked at your code but here is the mechanism which worked for me:
1. 将 setOnCheckedChangeListener 放入您的复选框.
1. Put setOnCheckedChangeListener to your checkbox.
2. 如果 Checkbox 是 Checked 然后将该联系人添加到 arraylist.
2. If Checkbox is Checked then add that contact to arraylist.
3. 如果 CheckBox 是 unchecked，则从 arraylist 中删除该联系人.
3. If CheckBox is unchecked then remove that contact from arraylist.
4. 使用 startActivityForResult() 开始您的联系人列表活动并覆盖 onActivityResult().
4. Start your contact list activity with startActivityForResult() and override onActivityResult().
5.在离开联系人活动之前设置你的在意图中选择的联系人.
6.在您的活动中接收选定的联系人.
6. Receive the selected contacts in your activity.
7. 现在您已经选择了可以在 TextView 中显示的联系人.
7. Now you have selected contacts which you can show in TextView.
注意:您需要为此使用自定义列表适配器:
Note: You need to use custom list adapter for this:
自定义列表适配器:
public class YourAdapterName extends BaseAdapter{
private Context mContext;
private ArrayList<string> mValuestoShow;
/**
* Constructor to be called to initialize adapter with values.
* @param context
* @param vector
*/
public YourAdapterName(Context context, ArrayList<string> contacts){
mContext = context;
mValuestoShow = contacts;
}
public int getCount() {
if(null != mValuestoShow){
return mValuestoShow.size();
}
return 0;
}
public Object getItem(int position) {
if(position < mValuestoShow.size())
return mValuestoShow.get(position);
else
return null;
}
public long getItemId(int position) {
return 0;
}
/**
* This method can be override to enable/disable particular list row.
*/
@Override
public boolean isEnabled(int position) {
//Write your code here......
return super.isEnabled(position);
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater li =(LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = li.inflate(R.layout.contact_list_layout, null);
holder = new ViewHolder();
holder.name = (TextView)convertView.findViewById(R.id.name);
holder.checkbox = (CheckBox)convertView.findViewById(R.id.checkbox);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.name.setText(text goes here ....);
holder.checkbox.setOnCheckedChangeListener(new CheckBox.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if ( isChecked )
//Add contact...
else
//Remove contact.
}
});
return convertView;
}
class ViewHolder {
TextView name;
CheckBox checkbox;
}
}
your_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp" >
<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="50dp"
android:ellipsize="end"
android:singleLine="true"
android:textColor="@android:color/black" />
<CheckBox
android:id="@+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true" />
</RelativeLayout>
