我有一个联系人列表活动，但想要添加一些功能，以便当您点击联系人时它将开始拨打他们的电话号码。我尝试过这段代码片段但是当我点击一个联系人时没有任何反应：
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + currentContact.getPhone()));
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return;
}
try{
((Activity) context).startActivity(callIntent);
}catch (Exception e){
e.printStackTrace();
}
所有联系活动代码：
public class ContactList extends ActionBarActivity {
Spinner spinner, spinnerFilter;
EditText nameTxt, phoneTxt, emailTxt, addressTxt;
ImageView contactImageimgView, btnSort;
List<Contact> Contacts = new ArrayList<Contact>();

AlertDialog alertDialog;
Bitmap photoTaken;
String userId;
boolean isReverseEnabledPriority = false, isReverseEnabledName = false;
//ArrayList<Contact> contacts;

你试过这段代码吗？
Uri number = Uri.parse("tel:123456789");
Intent callIntent = new Intent(Intent.ACTION_DIAL, number);
startActivity(callIntent);
