记账本APP6

对记账本里的记一笔中所填入的数据添加至Sqlite数据库中，之前写体温APP的时候有用到Sqlite数据库，所以在链接数据库这一方面比较方便

MainActivity.java

 1 public class MainActivity extends AppCompatActivity {
 2 
 3     //记一笔
 4     private ImageButton mAdd;
 5 
 6     @Override
 7     protected void onCreate(Bundle savedInstanceState) {
 8         super.onCreate(savedInstanceState);
 9         setContentView(R.layout.activity_main);
10 
11         mAdd=findViewById(R.id.main_btn_add);
12         mAdd.setOnClickListener(new View.OnClickListener() {
13             @Override
14             public void onClick(View v) {
15                 //跳转到记一笔界面
16                 Toast.makeText(MainActivity.this,"跳转记一笔界面成功",Toast.LENGTH_SHORT).show();
17                 Intent intent=null;
18                 intent=new Intent(MainActivity.this,AddActivity.class);
19                 startActivity(intent);
20             }
21         });
22     }

MyDataBaseHelper.java

10         mContext=context;
11     }
12 
13     @Override
14     public void onCreate(SQLiteDatabase database){
15         //创建时的回调
16         String sql="create table " + "AcountBook" + "(type varchar,name varchar,money varchar,time varchar,note varchar)";
17         database.execSQL(sql);
18     }
19 
20     @Override
