我正在制作短信应用程序并希望在我的
Android应用程序中访问联系人
.
.
我想访问联系人,就像他们在实际联系人列表中的位置一样.选择后,我需要返回我的活动,我可以向该人发送短信.或者是否可以访问存储联系人的数据库？
我的代码如下所示：
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); String no = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
我的LogCat看起来像这样：

谁能帮我？
解决方法
使用此代码选择联系人：
Button button = (Button)findViewById(R.id.pickcontact);
button.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent,PICK_CONTACT);
}
});
@Override public void onActivityResult(int reqCode,int resultCode,Intent data){ super.onActivityResult(reqCode,resultCode,data);
switch(reqCode)
{
case (PICK_CONTACT):
if (resultCode == Activity.RESULT_OK)
{
Uri contactData = data.getData();
Cursor c = managedQuery(contactData,null,null);
if (c.moveToFirst())
{
String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String hasPhone =
c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (hasPhone.equalsIgnoreCase("1"))
{
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null);
phones.moveToFirst();
String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Toast.makeText(getApplicationContext(),cNumber,Toast.LENGTH_SHORT).show();
setCn(cNumber);
}
}
}
}
}
