Android（四）数据存储之四ContentProvider 2

3.测试SQLite示例程序的ContentProvider

       ContentProvider即然是提供给其他应用访问本应用数据的，所以我们需要另创建一个Android应用，来测试SQLite示例程序的ContentProvider。我在此只列出query的测试方法testQuery：

public void testQuery() throws Throwable {

         ContentResolver contentResolver = this.getContext()

                            .getContentResolver();

         Uri uri = Uri

                            .parse("content://com.changcheng.sqlite.provider/contact");

         Cursor cursor = contentResolver.query(uri, new String[] { "_id",

                            "name", "phone" }, null, null, "_id desc");

         while (cursor.moveToNext()) {

                   Log.i(TAG, "_id=" + cursor.getInt(0) + ",name="

                                     + cursor.getString(1) + ",phone=" + cursor.getString(2));

         }

}
