2、ProviderTest

测试类

[java

package com.njupt.pc1;

import android.content.ContentProvider;

import android.content.ContentResolver;

import android.content.ContentValues;

import android.database.Cursor;

import android.net.Uri;

import android.test.AndroidTestCase;

public class ProviderTest extends AndroidTestCase{

public void testQuery(){

ContentResolver resolver = getContext().getContentResolver();

Uri uri = Uri.parse("content://jd_love_ztmm/person");

Cursor c = resolver.query(uri,null,null,null,null);

while(c.moveToNext()){

Integer id = c.getInt(0);

String name = c.getString(1);

Integer balance = c.getInt(2);

System.out.println(new Person(id,name,balance));

}

public void testDelete(){

ContentResolver resolver = getContext().getContentResolver();

Uri uri = Uri.parse("content://jd_love_ztmm/person/1");

resolver.delete(uri, null, null);

}

public void testUpdate(){

ContentResolver resolver = getContext().getContentResolver();

Uri uri = Uri.parse("content://jd_love_ztmm/person/2");

ContentValues values = new ContentValues();

values.put("name", "刘诗诗是java程序员的女神");

values.put("balance", "65000");

resolver.update(uri, values, null, null);

}

public void testInsert(){

ContentResolver resolver = getContext().getContentResolver();

Uri uri = Uri.parse("content://jd_love_ztmm/person");

ContentValues values = new ContentValues();

values.put("name","刘诗诗是C++程序员的女神" );

values.put("balance", "70000");

resolver.insert(uri, values);

}

3、DBTest

[java

package com.njupt.practice_contentprovider1.dao;

import java.util.List;

import java.util.Random;

import com.njupt.practice_contentprovider1.domain.Person;

import android.test.AndroidTestCase;

public class DBTest extends AndroidTestCase {

public void testCreateDataBase() {

DBOpenHelper helper = new DBOpenHelper(getContext());

helper.getWritableDatabase();

}

public void testInsert() {
