团队冲刺第三天

1.今天修补了一下之前的bug。之前的问题是。偶尔会出现定位失败。并且光标不显示的问题。

最后发现是因为android版本6.0以上的用户。在使用百度定位的时候需要一些另外的权限，并且代码本身不能自己设置的问题。最后完美解决。

主要是对百度定位的相关api的了解不够全面。明天将会主要用来研究怎样实现运动轨迹的显示。

具体的解决代码如下：

    private static final int REQUEST_CODE = 1;
    private void requestRunTimePermission() {
        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,Manifest.permission.ACCESS_COARSE_LOCATION)
                || ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,Manifest.permission.ACCESS_FINE_LOCATION)
                || ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,Manifest.permission.WRITE_EXTERNAL_STORAGE)
                || ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,Manifest.permission.READ_PHONE_STATE)) {
            /*
             *  如果没有获得过用户的权限许可，则向用户申请
             */

            Snackbar.make(MainActivity.this.findViewById(R.id.butttonunder2), "定位",
                    Snackbar.LENGTH_INDEFINITE).setAction("权限申请", new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    ActivityCompat.requestPermissions(MainActivity.this,
                            new String[]{
                                    Manifest.permission.ACCESS_COARSE_LOCATION,
                                    Manifest.permission.ACCESS_FINE_LOCATION,
                                    Manifest.permission.WRITE_EXTERNAL_STORAGE,
                                    Manifest.permission.READ_PHONE_STATE
                            },REQUEST_CODE);
                }
            }).show();
        } else {
            /*
             *  如果已经获得过用户的权限许可了，则直接申请运行时权限即可
             */
            ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{
                            Manifest.permission.ACCESS_COARSE_LOCATION,
                            Manifest.permission.ACCESS_FINE_LOCATION,
                            Manifest.permission.WRITE_EXTERNAL_STORAGE,
                            Manifest.permission.READ_PHONE_STATE
                    },REQUEST_CODE);
        }
    }

2.今天算是小有成就，完成了我自己第一部分任务的所有内容，包括注册登录的所有功能，以及一些小的细节，过程中遇到了一些问题，但都不是什么大的问题，相对昨天来说轻松了不少，下面是一些效果图以及主要代码

        //判断是否记住过密码,如果上次登录记住过密码，则显示密码
        etLoginUsername.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {//获得焦点
                } else {

                    if (!TextUtils.isEmpty(username)) {

                            String userpsw = bean.userpsw;
                            Log.d("volley", usercheck);
                            if (usercheck.equals("1")) {

                                etLoginPwd.setText(userpsw);

                            }
                        } else {
                            etLoginUsername.setText("");
                            etLoginUsername.setHint("账户不存在，请先注册");
                        }
                    } else {
                        etLoginUsername.setHint("请输入用户名");
                    }
                }
            }
        });
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.bt_login_register:

                if (!TextUtils.isEmpty(username) && !TextUtils.isEmpty(userpsw)) {
                    User bean = muserOperator.isExit(username);
//                    String userpsws = bean.userpsw;
//                    Log.d("volley", userpsws);
                    if (bean != null && bean.userpsw.equals(userpsw)) {
                        if (cbRememberLogin.isChecked()) {
                            String usercheck = "1";
                            User beans = new User(username, usercheck);
                            muserOperator.isRemPsw(beans);
                        }else{
                            String usercheck = "0";
                            User beans = new User(username, usercheck);
                            muserOperator.isRemPsw(beans);
                        }

                            startActivity(intent);
                            finish();

                    } else {
                        Toast.makeText(this, "密码错误", Toast.LENGTH_SHORT).show();
                    }

        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 0x11 && resultCode == 0x11) {
            Bundle bundle = data.getExtras();
            String username = bundle.getString("username");
            String password = bundle.getString("password");
            etLoginPwd.setText(password);
            etLoginUsername.setText(username);
        }
    }
}

3.今天的我毫无成就感，自我忏悔了一番，这就是不从头好好学习的结果，半路截取知识和代码真的太累了。

修改了两个多小时的bug,昨天的问题依旧没有解决，突然间感觉之前写的都是无用的代码，只能靠双休从头来补了。加油吧！
