Lost and Found（结对项目）登录注册

利用Bmob实现登录和注册首先要在bmob官网上下载对应的sdk，导入到libs里面就可以了。需要在bmob上建立应用，得到id（这些在前一博客中已经提到）所以话不多说直接上代码。

注册按钮

//注册点击
	public void dregi(View view){
		Intent intentlogin = new Intent();
		intentlogin.setClass(SecondActivity.this,MainActivity.class);
		startActivity(intentlogin);

登录按钮

//登录点击
    public void dlogin(View view){
        String name=mname.getText().toString();
        String password=mpassword.getText().toString();
        if(name.equals("")||password.equals("")){
            Toast.makeText(this, "帐号或密码不能为空", Toast.LENGTH_LONG).show();
            return;
        }
        BmobQuery<user> query=new BmobQuery<user>();
        query.addWhereEqualTo("name", name);
        query.addWhereEqualTo("password", password);
        query.findObjects(new FindListener<user>() {
            
            @Override
            public void done(List<user> arg0, BmobException e) {
                // TODO Auto-generated method stub
                if(e==null){
                String gname=arg0.get(0).getName().toString();
                String gpassword=arg0.get(0).getPassword().toString();
                String name=mname.getText().toString();
                String password=mpassword.getText().toString();
                Toast.makeText(SecondActivity.this, gname, Toast.LENGTH_LONG).show();
                if(gname.equals(name)&&gpassword.equals(password))
                {
                    Intent seccess = new Intent();
                    seccess.setClass(SecondActivity.this, ThridActivity.class);
                    startActivity(seccess);
                }
                
                }
                else{
                    Toast.makeText(SecondActivity.this, "帐号或密码有误", Toast.LENGTH_LONG).show();
                }
                

返回登录页面

public void ret(View view){
     
        Intent intent1 = new Intent();
        intent1.setClass(MainActivity.this, SecondActivity.class);
        MainActivity.this.startActivity(intent1);
        
        
    }
