Android 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;
	}

	@Override
	public 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);
