Android Project Actual Series - based on my module in Savvy Valley

Keywords: Mobile Android Java xml encoding

Please be patient to read this module because of its large content and length.

My module is divided into four parts

[ ] My interface
[ ] Set up interface
[x] Modify password interface
[x] Set Secret Security and Retrieve Password

1. Modify Password

1. Create a password modification interface

In the com.boxuegu.activity package, create a java class named ModifyPswActivity.Create a layout file named activity_modify_psw under the res/layout folder.

2. Modify password interface code--activity_modify_psw.xml

                    Intent intent = new Intent(ModifyPswActivity.this, LoginActivity.class);
                    startActivity(intent);
                    SettingActivity.instance.finish();   //Close Setup Interface
                    ModifyPswActivity.this.finish();  //Close this interface
                }
            }
        });
    }

    //Gets the string on the control
    private void getEditString(){
        originalPsw = et_original_psw.getText().toString().trim();
        newPsw = et_new_psw.getText().toString().trim();
        newPswAgain=et_new_psw_again.getText().toString().trim();

        SharedPreferences.Editor editor = sp.edit();  //Get Editor
        editor.putString(userName,md5Psw);   //Save New Password
        editor.commit();   //Submit modifications
    }

    //Read the original password from SharedPreferences
    private String readPsw(){
        SharedPreferences sp = getSharedPreferences("loginInfo", MODE_PRIVATE);
        String spPsw = sp.getString(userName, "");
        return spPsw;
    }
}

4. Modify Setup Interface Code

Find the init method in the SettingActivity.java file and add the following code below the comment//jump to the interface where the password is changed

Intent intent = new Intent(SettingActivity.this,ModifyPswActivity.class);
startActivity(intent);

2. Setting up secret protection and retrieving passwords

1. Create a password-setting and password-retrieving interface

In the com.boxuegu.activity package, create a java class named FindPswActivity.Create a layout file named activity_find_psw under the res/layout folder.Import the desired picture find_psw_icon.png into the drawable folder.

2. Create an interface code for setting secret and retrieving passwords--activity_find_psw.xml

4. Modify Code
