在xml中创建一个按钮 并在Activity中调用xml 按钮联系人=(按钮)findViewById(R.id.contacts); 然后为按钮创建一个onclick监听器 contacts.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Contacts.Intents.Insert.ACTION,
Contacts.People.CONTENT_URI);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
intent.putExtra(ContactsContract.Intents.Insert.NAME, entryname);
intent.putExtra(ContactsContract.Intents.Insert.PHONE, phone);
startActivity(intent);
finish();
}
});
