我在嘗試創建應用程序。匹配被叫號碼的方法
首先,按Button
獲取地址簿的電話號碼並保存。
然後,每次來電時,它都會檢查保存的電話號碼,如果不在地址簿中,則會發出警告。
使用領域,存儲通訊簿的電話號碼是成功的。 但是,如果我在真實機器上接聽來電,應用程序將被強行終止。
我不知道驗證電話號碼的方法是否不正確,我無法檢索保存的電話號碼,或者它需要太多時間。 給我建議,以改進
MainActivity.java
public class MainActivity extends AppCompatActivity {
PhoneReceiver phoneStateListener;
TelephonyManager manager;
public Button getPhoneList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
phoneStateListener = new PhoneReceiver(this);
manager = ((TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE));
getPhoneList = (Button)this.findViewById(R.id.phoneList);
getPhoneList.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
CreatePhoneNumbers();
}
});
}
public void CreatePhoneNumbers() {
final Cursor addressTable = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
RealmConfiguration realmConfiguration = new RealmConfiguration.Builder(this).build();
Realm realm = Realm.getInstance(realmConfiguration);
User user = new User();
if (addressTable != null) {
while (addressTable.moveToNext()) {
realm.executeTransaction(new Realm.Transaction(){
@Override
public void execute(Realm realm) {
User u = realm.createObject(User.class);
u.setPhoneNumber(addressTable.getString(addressTable.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
Log.d("Data", u.toString());
}
});
}
realm.close();
addressTable.close();
}
}
}
PhoneReceiver.java
class PhoneReceiver extends PhoneStateListener {
private Context context;
PhoneReceiver(Context context) {
this.context = context;
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
RealmConfiguration realmConfiguration = new RealmConfiguration.Builder(context).build();
Realm realm = Realm.getInstance(realmConfiguration);
RealmQuery<User> results = realm.where(User.class).equalTo("phoneNumber", incomingNumber);
int count = (int) results.count();
if (count > 0) {
Toast.makeText(context, "Calling" + incomingNumber, Toast.LENGTH_LONG).show();
} else {
Dialog();
}
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Toast.makeText(context, "Offhook!!" + incomingNumber, Toast.LENGTH_LONG).show();
break;
}
}
}
