【问题描述】：
我正在开发一个应用程序，我想阻止某些特定号码的短信。为此，我有一个 Activity 和第二个是 BroadcastReceiver 类。在 Activity 我有一个列表，用户将在其中输入他想要阻止的数字。但我不知道列表号将如何访问 BroadcastReceiver 类来阻止它。我在 BroadcastReceiver 类中访问一个 ArrayAdapter，但它不执行阻止呼叫。任何人帮助我..提前谢谢..
短信锁.java
public class SmsLock extends BroadcastReceiver {
final SmsManager sms = SmsManager.getDefault();
String phoneNumber;
String senderNum;
NumberListActivity ma = new NumberListActivity();
NumberListActivity num = new NumberListActivity();
String[] number = new String[] { "+923327765798", "+923219750751",
"+923445508726" };
@Override
public void onReceive(Context context, Intent intent) {
ArrayAdapter<String> adapter = ma.getArrayAdapter();
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage
.createFromPdu((byte[]) pdusObj[i]);
phoneNumber = currentMessage.getDisplayOriginatingAddress();
senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
}
for (int i = 0; i < adapter.getCount(); i++) {
if (senderNum.contains(adapter.getItem(i))) {
abortBroadcast();
}
}
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" + e);
}
}
}
NumberListActivity.java
public class NumberListActivity extends Activity {
SharedPreferences preferences1;
SharedPreferences.Editor spEditor1;
int count1 = 0;
ListView numList1;
Button btnAdd1;
ArrayList<String> list1 = new ArrayList<String>();
ArrayAdapter<String> adapter1;
public static final String Place1 = "placeKey";
SmsLock brd = new SmsLock();
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.sms_list);
preferences1 = getSharedPreferences("Place1", Context.MODE_PRIVATE);
spEditor1 = preferences1.edit();
count1 = preferences1.getInt("count1", 0);
if (count1 > 0) {
for (int i = 0; i < count1; i++) {
list1.add(preferences1.getString("Value1[" + i + "]", ""));
}
}
final EditText edit = (EditText) findViewById(R.id.Item);
numList1 = (ListView) findViewById(R.id.Smslist);
btnAdd1 = (Button) findViewById(R.id.Add);
adapter1 = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, list1);
numList1.setAdapter(adapter1);
numList1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
/*
* list.remove(position); //preferences.edit().clear().commit();
* preferences.edit().remove("Value["+position+"]").commit();
* //count-=1; // adapter.remove(adapter.getItem(position));
*/
count1 = preferences1.getInt("count1", 0);
// if (count > 0) {
for (int i = position; i < count1; i++) {
// list.add();
if (i < count1)
spEditor1.putString(
"Value1[" + i + "]",
preferences1.getString("Value1[" + (i + 1)
+ "]", ""));
spEditor1.commit();
}
// }
list1.remove(position);
count1 -= 1;
spEditor1.putInt("count1", count1);
spEditor1.commit();
// preferences.edit().remove(position);
adapter1.notifyDataSetChanged();
}
});
btnAdd1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
// EditText edit = (EditText) findViewById(R.id.txtItem);
spEditor1.putString("Value1[" + count1 + "]", edit.getText()
.toString());
spEditor1.commit();
list1.add(preferences1.getString("Value1[" + count1 + "]", ""));
count1 += 1;
spEditor1.putInt("count1", count1);
spEditor1.commit();
adapter1.notifyDataSetChanged();
}
});
}
public ArrayAdapter<String> getArrayAdapter() {
return adapter1;
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
Intent int1 = new Intent(NumberListActivity.this, Main.class);
startActivity(int1);
finish();
}
}
【问题讨论】：
-
从活动中，您可以输入可以存储在 sqlite 和广播中的号码，就像您使用电话号码数组一样，而不是您需要从数据库中读取电话号码 :)
-
您要屏蔽短信或电话吗？
-
@Kedarnath:我用那个方法和结果也可以..但是如果用户想添加或删除一个数字那么他会做什么......
-
那你需要写一段代码把电话号码保存在sqlite中。
-
@Saqib:SMS And call both but this time I want only SMS.
