    一、最终效果展示:

     

     

     

    二、界面布局设计:

    1、首页界面布局设计activity_main.xml源代码

     1 <?xml version="1.0" encoding="utf-8"?>
     2 <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
     3     xmlns:app="http://schemas.android.com/apk/res-auto"
     4     xmlns:tools="http://schemas.android.com/tools"
     5     android:layout_width="match_parent"
     6     android:layout_height="match_parent"
     7     android:background="@drawable/dlandzc"
     8     tools:context=".MainActivity">
     9 
    10     <ImageView
    11         android:id="@+id/imageView"
    12         android:layout_width="169dp"
    13         android:layout_height="81dp"
    14         android:layout_marginStart="16dp"
    15         android:layout_marginLeft="16dp"
    16         android:onClick="deluclick"
    17         app:layout_constraintBottom_toBottomOf="parent"
    18         app:layout_constraintStart_toStartOf="parent"
    19         app:layout_constraintTop_toTopOf="parent"
    20         app:layout_constraintVertical_bias="0.944"
    21         app:srcCompat="@drawable/dl" />
    22 
    23     <ImageView
    24         android:id="@+id/imageView2"
    25         android:layout_width="194dp"
    26         android:layout_height="86dp"
    27         android:layout_marginStart="40dp"
    28         android:layout_marginLeft="40dp"
    29         android:onClick="zhucclick"
    30         app:layout_constraintBottom_toBottomOf="parent"
    31         app:layout_constraintStart_toEndOf="@+id/imageView"
    32         app:layout_constraintTop_toTopOf="parent"
    33         app:layout_constraintVertical_bias="0.944"
    34         app:srcCompat="@drawable/zc" />
    35 </androidx.constraintlayout.widget.ConstraintLayout>

    2、注册界面布局设计activity_main2.xml源代码

    135         app:srcCompat="@drawable/zhuc" />
    136 
    137 </androidx.constraintlayout.widget.ConstraintLayout>

    3、登录界面布局设计activity_main2.xml源代码

     1 <?xml version="1.0" encoding="utf-8"?>
     2 <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
     3     xmlns:app="http://schemas.android.com/apk/res-auto"
     4     xmlns:tools="http://schemas.android.com/tools"
     5     android:layout_width="match_parent"
     6     android:layout_height="match_parent"
     7     android:background="@drawable/dljm"
     8     tools:context=".Main3Activity">
     9 
    10     <EditText
    11         android:id="@+id/et"
    12         android:layout_width="wrap_content"
    13         android:layout_height="wrap_content"
    14         android:layout_marginTop="308dp"
    15         android:ems="10"
    16         android:hint="请输入用户名"
    17         android:inputType="textPersonName"
    18         android:textColorHint="#C3A476"
    19         app:layout_constraintEnd_toEndOf="parent"
    20         app:layout_constraintStart_toStartOf="parent"
    21         app:layout_constraintTop_toTopOf="parent" />
    22 
    23     <EditText
    24         android:id="@+id/editText3"
    25         android:layout_width="wrap_content"
    26         android:layout_height="wrap_content"
    27         android:layout_marginTop="12dp"
    28         android:ems="10"
    29         android:hint="请输入密码"
    30         android:inputType="textPassword"
    31         android:textColorHint="#C3A476"
    32         app:layout_constraintEnd_toEndOf="parent"
    33         app:layout_constraintStart_toStartOf="parent"
    34         app:layout_constraintTop_toBottomOf="@+id/et" />
    35 
    36     <ImageView
    37         android:id="@+id/dlu2"
    38         android:layout_width="wrap_content"
    39         android:layout_height="wrap_content"
    40         android:layout_marginTop="84dp"
    41         android:onClick="dl"
    42         app:layout_constraintEnd_toEndOf="parent"
    43         app:layout_constraintHorizontal_bias="0.496"
    44         app:layout_constraintStart_toStartOf="parent"
    45         app:layout_constraintTop_toBottomOf="@+id/editText3"
    46         app:srcCompat="@drawable/dlu2" />
    47 
    48     <TextView
    49         android:id="@+id/textView3"
    50         android:layout_width="wrap_content"
    51         android:layout_height="wrap_content"
    52         android:layout_marginTop="20dp"
    53         android:onClick="wjmm"
    54         android:text="忘记密码"
    55         android:textColor="#C3A476"
    56         android:textSize="24sp"
    57         app:layout_constraintEnd_toEndOf="parent"
    58         app:layout_constraintHorizontal_bias="0.873"
    59         app:layout_constraintStart_toStartOf="parent"
    60         app:layout_constraintTop_toBottomOf="@+id/editText3" />
    61 </androidx.constraintlayout.widget.ConstraintLayout>

    三、手机上方显示状态栏颜色更改R/values/color.xml

     

    1 <?xml version="1.0" encoding="utf-8"?>
    2 <resources>
    3     <color name="colorPrimary">#FFC444</color>
    4     <color name="colorPrimaryDark">#FFC444</color>
    5     <color name="colorAccent">#FFC444</color>
    6 </resources>

     

    四、模块标题栏中标题更改R/values/String.xml

     1 <resources> 2 <string name="app_name">MKOPlayer</string> 3 </resources> 

    五、功能实现

    1、首页功能实现MainActivity.java

     1 package com.example.adf;
     2 
     3 import androidx.appcompat.app.AppCompatActivity;
     4 
     5 import android.content.Intent;
     6 import android.os.Bundle;
     7 import android.view.View;
     8 
     9 public class MainActivity extends AppCompatActivity {
    10 
    11     @Override
    12     protected void onCreate(Bundle savedInstanceState) {
    13         super.onCreate(savedInstanceState);
    14         setContentView(R.layout.activity_main);
    15     }
    16 
    17     public void deluclick(View view) {
    18         Intent intent=new Intent(MainActivity.this,Main3Activity.class);
    19         startActivity(intent);
    20 
    21     }
    22 
    23     public void zhucclick(View view) {
    24         Intent intent=new Intent(MainActivity.this,Main2Activity.class);
    25         startActivity(intent);
    26     }
    27 }

    2、注册界面功能实现Main2Activity.java

     1 package com.example.adf;
     2 
     3 import androidx.appcompat.app.AppCompatActivity;
     4 
     5 import android.content.Intent;
     6 import android.os.Bundle;
     7 import android.view.View;
     8 import android.widget.EditText;
     9 import android.widget.ImageView;
    10 import android.widget.Toast;
    11 
    12 public class Main2Activity extends AppCompatActivity {
    13 EditText name,pwd;
    14 ImageView zhuce1;
    15 
    16     @Override
    17     protected void onCreate(Bundle savedInstanceState) {
    18         super.onCreate(savedInstanceState);
    19         setContentView(R.layout.activity_main2);
    20 
    21         name=findViewById(R.id.name);
    22         pwd=findViewById(R.id.editText2);
    23         zhuce1=findViewById(R.id.zhuce1);
    24 
    25 
    26     }
    27 
    28     public void zc1(View view) {
    29         String username=name.getText().toString();
    30         String password=pwd.getText().toString();
    31         if (username.equals("")||password.equals("")){
    32             Toast.makeText(this, "抱歉,注册失败,用户名或者密码不能为空;请补充完整", Toast.LENGTH_SHORT).show();
    33         }
    34         else{
    35 
    36             Intent intent=new Intent(Main2Activity.this,Main3Activity.class);
    37             intent.putExtra("username",username);
    38             intent.putExtra("password",password);
    39             startActivity(intent);
    40 
    41         }
    42     }
    43 }

    3、登录界面功能实现Main3Activity.java

     1 package com.example.adf;
     2 
     3 import androidx.appcompat.app.AppCompatActivity;
     4 
     5 import android.content.Intent;
     6 import android.net.Uri;
     7 import android.os.Bundle;
     8 import android.view.View;
     9 import android.widget.EditText;
    10 import android.widget.ImageView;
    11 import android.widget.TextView;
    12 import android.widget.Toast;
    13 
    14 public class Main3Activity extends AppCompatActivity {
    15 EditText et1,et2;
    16 ImageView dlu2;
    17     @Override
    18     protected void onCreate(Bundle savedInstanceState) {
    19         super.onCreate(savedInstanceState);
    20         setContentView(R.layout.activity_main3);
    21 
    22 
    23         et1=findViewById(R.id.et);
    24         et2=findViewById(R.id.editText3);
    25         dlu2=findViewById(R.id.dlu2);
    26 
    27 
    28     }
    29 
    30     public void dl(View view) {
    31         String  mingzi=et1.getText().toString();
    32         String  mima=et2.getText().toString();
    33         Intent intent=getIntent();
    34         String uer=intent.getStringExtra("username");
    35         String pwd =intent.getStringExtra("password");
    36         if (mingzi.equals(uer)&&mima.equals(pwd)){
