Andoid2.X联系人表名字段名

使用时应用系统定义的常量，这只是演示一下各字段名称。

public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		Cursor cur = this.getContentResolver().query(
				ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
		int columnNumber = cur.getColumnCount();
		String cn = "";
		for (int i = 0; i < columnNumber; i++)

		{

			String temp = cur.getColumnName(i);
			cn = cn + "\nlistColumnNames" + i + "\t" + temp;

		}

		cur.close();

		TextView tv = new TextView(this);
		tv.setText(cn);
		setContentView(tv);
