Android 中未接来电的广播接收器

有谁知道未接来电的意图是什么。实际上，我想在我的应用程序中发送有关未接来电和来电的短信。

您需要使用 ContentObserver

public class MissedCallsContentObserver extends ContentObserver
{
    public MissedCallsContentObserver()
    {
        super(null);
    }

    @Override
    public void onChange(boolean selfChange)
    {
        Cursor cursor = getContentResolver().query(
            Calls.CONTENT_URI, 
            null, 
            Calls.TYPE +  " = ? AND " + Calls.NEW + " = ?", 
            new String[] { Integer.toString(Calls.MISSED_TYPE), "1" }, 
            Calls.DATE + " DESC ");

        //this is the number of missed calls
        //for your case you may need to track this number
        //so that you can figure out when it changes
        cursor.getCount(); 

        cursor.close();
    }
}

在您的应用程序中，您只需执行以下操作：

MissedCallsContentObserver mcco = new MissedCallsContentObserver();
getApplicationContext().getContentResolver().registerContentObserver(Calls.CONTENT_URI, true, mcco);
