我想从联系人列表中选择电话号码 我写这段代码来挑选电话号码，但这会抛出异常
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case CONTACT_PICKER_RESULT:
Bundle extras = data.getExtras();
Set<String> keys = extras.keySet();
Iterator<String> iterate = keys.iterator();
while (iterate.hasNext()) {
String key = iterate.next();
Log.v("R", key + "[" + extras.get(key) + "]");
}
Uri result = data.getData();
Cursor c = getContentResolver().query(result,null,null,null,null);
try {
c.moveToFirst();
String name = c
.getString(c
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.i("name", name);
String contactId = c.getString(c
.getColumnIndex(ContactsContract.Contacts._ID));
Log.i("Contact Id : ", contactId);
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + contactId, null, null);
final String[] contactNumbers = new String[phones
.getCount()];
int count = 0;
while (phones.moveToNext()) {
contactNumbers[count] = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
count++;
}
phones.close();
if (contactNumbers.length > 1 ) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Call Number");
builder.setItems(contactNumbers, new OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ContactActivity.roamNumber
.setText(contactNumbers[which]);
}
});
builder.create().show();
} else {
ContactActivity.roamNumber
.setText(contactNumbers[0]);
}
} finally {
c.close();
}
break;
}
} else {
// gracefully handle failure
Log.i("", "Warning: activity result not ok");
}
}

问题是什么？
答案 0 :(得分：0)
我使用此代码解决问题：
Uri result = data.getData();
Cursor c = getContentResolver().query(result, null, null, null,
null);
Log.d("Row Count c", c.getCount() +"");
Log.d("result", result +"");
try {
c.moveToFirst();
String name = c
.getString(c
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.i("name", name);
String contactId = c.getString(c
.getColumnIndex(ContactsContract.Contacts._ID));
Log.i("Contact Id : ", contactId);
Cursor phoness = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + contactId, null, null);
Cursor phones = managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME +
" like ('"+name+"')", null, null);
if (phones.getCount() == 0) {
AlertDialog.Builder numbersBuilder = new AlertDialog.Builder(this);
numbersBuilder.setMessage("No Number Found ..!")
.setCancelable(true);
AlertDialog alert = numbersBuilder.create();
alert.show();
ContactActivity.roamNumber
.setText("");
break;
}
final String[] contactNumbers = new String[phones
.getCount()];
int count = 0;
while (phones.moveToNext()) {
contactNumbers[count] = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
count++;
}
phones.close();
if (contactNumbers.length > 1 ) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Call Number");
builder.setItems(contactNumbers, new OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ContactActivity.roamNumber
.setText(contactNumbers[which]);
}
});
builder.create().show();
} else {
ContactActivity.roamNumber
.setText(contactNumbers[0]);
}
} finally {
c.close();
}
