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));
???????? }
}
