当用户在联系人列表中时,他/她应该从联系人列表中选择一个人,联系人活动将关闭并调用onActivityResult();但是当我点击联系人页面上角的后退按钮或取消按钮时,光标将为空,并且出现空指针异常。和想法?
代码:
selectContactButton.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
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) //I tried to do if intent!=null then run this codes but there is the same error
{
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
cursor.moveToNext();
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
editName.setText(name); //edittext view
}
}
