【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向其发送 SMS 消息。到目前为止，我所做的是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。
所以我在做什么时遇到了麻烦。 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
对不起，如果我的代码难以理解，请询问您是否需要澄清。
这是显示列表视图的 XML，称为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>
这是我的活动，它把所有东西都放在一起。
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
<?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:id="@+id/contactEntryText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/contactEntryText" />
</LinearLayout>
<?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"

<ListView

android:layout_width="fill_parent"

<Button

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/showInvisible" />
</LinearLayout>
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。
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/contacts"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:gravity="center"
android:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingTop="10dp"
android:text="@string/contacts"
android:textAppearance="?android:attr/textAppearanceLarge" />
<!-- android:textColor="#fff" android:background="@drawable/header" for header background -->
<Button
android:id="@+id/contactsButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="@string/contacts" />
</RelativeLayout>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/enter_contact"
android:textAppearance="?android:attr/textAppearanceMedium" />
<AutoCompleteTextView
android:id="@+id/contactnumber"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/to" >
<requestFocus />
</AutoCompleteTextView>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/message_to_send"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="@+id/invite_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/message_join" />
<Button
android:id="@+id/sendtxt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="doLaunchContactPicker"
android:text="@string/send_txt" />
</LinearLayout>
</ScrollView>
