如何在Android SDK 2.2上检索未接来电

Question

在我的应用程序中,当呼叫到来但用户没有回答时,我应该做一些动作.

我在android.telephony和NotificationManager中搜索过,但是我还没有找到解决这个问题的方法.

有人知道如何知道手机上是否有未接来电？

这是可以查询未接来电的通话记录的代码.基本上,你必须以某种方式触发这一点,并确保你给呼叫记录一些时间(几秒钟应该这样做)来写信息,否则如果你太快检查呼叫记录你将找不到最近的呼叫.

final String[] projection = null;
final String selection = null;
final String[] selectionArgs = null;
final String sortOrder = android.provider.CallLog.Calls.DATE + " DESC";
Cursor cursor = null;
try{
    cursor = context.getContentResolver().query(
            Uri.parse("content://call_log/calls"),
            projection,
            selection,
            selectionArgs,
            sortOrder);
    while (cursor.moveToNext()) { 
        String callLogID = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls._ID));
        String callNumber = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.NUMBER));
        String callDate = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.DATE));
        String callType = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.TYPE));
        String isCallNew = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.NEW));
        if(Integer.parseInt(callType) == MISSED_CALL_TYPE && Integer.parseInt(isCallNew) > 0){
            if (_debug) Log.v("Missed Call Found: " + callNumber);
        }
    }
}catch(Exception ex){
    if (_debug) Log.e("ERROR: " + ex.toString());
}finally{
    cursor.close();
}

希望这个对你有帮助.
