Android(安卓)Call Log and SMS Delete 电话记录和短信删除

public class CallContentObserver extends ContentObserver {private final static String strUriInbox = "content://call_log/calls";private final static Uri uriCall = Uri.parse(strUriInbox);private String phoneNum;private Context context;public CallContentObserver(Context context, String phoneNum, Handler handler) {super(handler);this.context = context;this.phoneNum = phoneNum;}@Overridepublic void onChange(boolean selfChange) {super.onChange(selfChange);Cursor c = context.getContentResolver().query(uriCall,new String[] { "_id", "number", "date" }, null, null, null);if (c != null && c.moveToFirst()) {String num = c.getString(1);String id = c.getString(0);if (num != null &&phoneNum!=null&& num.equals(phoneNum)) {context.getContentResolver().delete(uriCall, "_id=" + id,null);}// for(int i =0; i < c.getColumnCount(); i++)// {// String strColumnName = c.getColumnName(i);// String strColumnValue = c.getString(i);// Log.e("i", "i="+i);// Log.e("strColumnName", "strColumnName="+strColumnName);// Log.e("strColumnValue", "strColumnValue="+strColumnValue);// }c.close();}}}

调用

context.getContentResolver().registerContentObserver(Uri.parse("content://call_log"),true,new CallContentObserver(context,phoneNumber, null));

通过调用ContentObserver，当数据库变化后，才会处理。。此方法可用于如SMS删除，而不用Thread.sleep（不要用Sleep，因为效果非常差，有时无法删除）

短信可用下面的

private final static String strUriInbox = "content://sms/inbox";private final static Uri uriSms = Uri.parse(strUriInbox);

Cursor c = context.getContentResolver().query(uriSms,new String[] { "_id", "thread_id", "address","person", "date", "body" }, null, null,null);
