我正在開發一個android應用程序（使用Eclipse 3.5.2，Android 2.2），我需要從我的應用程序啓動內置聯繫人並從該模塊中從那裏選擇聯繫人。我正在使用下面的代碼。我很好地啓動內置聯繫人，但是當我選擇聯繫人時，它回到我的項目中的'onActivityResult'，結果崩潰爲「應用程序意外停止，強行關閉」。我正在模擬器上測試，只添加了一個測試聯繫人。崩潰發生在這條線上「遊標cursor = managedQuery（intent.getData（），null，null，null，null）;」Android：選擇聯繫人後崩潰
有人能告訴我我在做什麼錯在這裏嗎？
int PICK_CONTACT;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SetupView();
}
private void SetupView()
{
final Button selectContactBtn = (Button) findViewById(R.id.selectcontactBtn);
//selectContactBtn.setText("Test Button Text");
selectContactBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode==PICK_CONTACT && intent != null)
{
getContactInfo(intent);
}
}
protected void getContactInfo(Intent intent)
{
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);// CRASH HERE
cursor.moveToNext();
String contactID = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
Toast.makeText(this, "Contact Name: "+name, Toast.LENGTH_LONG).show();
}

這將有很大的幫助，如果你能提供的logcat的輸出，同時顯示異常。應該有一個stacktrace，並說明我添加了LogCat的錯誤 – Janusz
