MainActivity(登錄方法)
public class MainActivity extends AppCompatActivity { @BindView(R.id.editText) EditText editText; @BindView(R.id.editText2) EditText editText2; @BindView(R.id.button) Button button; @BindView(R.id.button2) Button button2; @BindView(R.id.activity_main) RelativeLayout activityMain; public static final String REGEX_PASSWORD = "^[a-zA-Z0-9]{6,16}$";//驗證密碼是否有特殊符號或長度不滿6位 private SQLiteDatabase w; private SQLiteDatabase r; private Mysqlist mys; private List<St> mdata; private String name; private String pass; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); mys = new Mysqlist(this, "zhu_c", null, 1);//使用halper創建數據庫 r=mys.getReadableDatabase(); w=mys.getWritableDatabase(); mdata=new ArrayList<St>(); Cursor query = r.rawQuery("select * from user_mo", null); while(query.moveToNext()){ int index1 = query.getColumnIndex("name"); int index2 = query.getColumnIndex("pass"); name = query.getString(index1); pass = query.getString(index2); mdata.add(new St(0, name, pass)); } } @OnClick({R.id.button, R.id.button2}) public void onViewClicked(View view) { switch (view.getId()) { case R.id.button: String name1 = editText.getText().toString().trim(); String pass1 = editText2.getText().toString().trim(); if (name1.equals(name)&&pass1.equals(pass)){ Toast.makeText(this,"登錄成功",Toast.LENGTH_SHORT).show(); Intent intent = new Intent(this, UserActivity.class); startActivity(intent); }else{ Toast.makeText(this,"賬號與密碼輸入不正確",Toast.LENGTH_SHORT).show(); } break; case R.id.button2: Intent intent1 = new Intent(this, ZhuActivity.class); startActivity(intent1); break; } } }
Mysqlist(創建數據庫)
public class Mysqlist extends SQLiteOpenHelper { private String sql="create table if not exists user_mo(_id Integer primary key autoincrement,name varchar(30) not null,pass varchar(50) not null)"; public Mysqlist(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) { super(context, name, factory, version); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(sql); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { // TODO Auto-generated method stub } }
ZhuActivity(注冊方法)
public class ZhuActivity extends AppCompatActivity { @BindView(R.id.editText3) EditText editText3; @BindView(R.id.editText4) EditText editText4; @BindView(R.id.button3) Button button3; @BindView(R.id.activity_zhu) RelativeLayout activityZhu; public static final String REGEX_PASSWORD = "^[a-zA-Z0-9]{6,16}$";//驗證密碼是否有特殊符號或長度不滿6位 private SQLiteDatabase sdb; private Mysqlist mys; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_zhu); ButterKnife.bind(this); mys = new Mysqlist(this, "zhu_c", null, 1);//使用halper創建數據庫 sdb=mys.getWritableDatabase(); } @OnClick(R.id.button3) public void onViewClicked() { //獲得賬號密碼 String name = editText3.getText().toString().trim(); String pass = editText4.getText().toString().trim(); if (name == null || "".equals(name) || pass == null || "".equals(pass)) { Toast.makeText(this, "賬號與密碼不能為空", Toast.LENGTH_SHORT).show(); } else { String number = editText3.getText().toString(); boolean judge = isMobile(number); String pa = editText4.getText().toString(); boolean judge1 = isPassword(pa); if (judge == true && judge1 == true) { Toast.makeText(this, "注冊成功", Toast.LENGTH_SHORT).show(); sdb.execSQL("insert into user_mo(name,pass)values('"+name+"','"+pass+"')"); Intent intent = new Intent(this, MainActivity.class); startActivity(intent);//啟動跳轉 } else { Toast.makeText(this, "手機號碼不法與密碼不能有特殊符號", Toast.LENGTH_SHORT).show(); } } } /** * 校驗密碼 * @param password * @return 校驗通過返回true,否則返回false */ public static boolean isPassword(String password) { return Pattern.matches(REGEX_PASSWORD, password); } /** * 驗證手機格式 */ public static boolean isMobile(String number) { /* 移動:134、135、136、137、138、139、150、151、157(TD)、158、159、187、188 聯通:130、131、132、152、155、156、185、186 電信:133、153、180、189、(1349衛通) 總結起來就是第一位必定為1,第二位必定為3或5或8,其他位置的可以為0-9 */ String num = "[1][358]\\d{9}";//"[1]"代表第1位為數字1,"[358]"代表第二位可以為3、5、8中的一個,"\\d{9}"代表后面是可以是0~9的數字,有9位。 if (TextUtils.isEmpty(number)) { return false; } else { //matches():字符串是否在給定的正則表達式匹配 return number.matches(num); } } }
St(工具類)
public class St { private int id; private String name; private String pass; public St(int id, String name, String pass) { this.id = id; this.name = name; this.pass = pass; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPass() { return pass; } public void setPass(String pass) { this.pass = pass; } @Override public String toString() { return "St{" + "id=" + id + ", name='" + name + '\'' + ", pass='" + pass + '\'' + '}'; } }
