启动应用界面

先来看一下启动界面:效果图如下:

uniapp智能家居APP android智能家居_xml_02


这是一个比较简单的布局由一个ImageView,Textview,Switch组成

其中Switch组件的样式由俩个文件组成,thumb.xml,track.xml(都在Drawable文件里面创建)

thumb.xml文件代码:

其实两个Item都是一样的效果,因为thumb代表的滑动的轨迹,可以理解为滑块。一个是被按下的状态,一个是普通时的状态

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@drawable/open_thumb"/>
<item android:drawable="@drawable/shut_thumb"/>

</selector>

因为两个item都是一样的,那我们就分析其中一个item,下面为滑块的效果

uniapp智能家居APP android智能家居_uniapp智能家居APP_03


open_thumb.xml代码如下:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- 高度40 -->
<size android:height="40dp" android:width="40dp"/>
<!-- 圆角弧度 20 -->
<corners android:radius="20dp"/>
<!-- 渐变色 -->
<gradient
    android:endColor="#eeeeee"
    android:startColor="#eeeeee" />
    <!--描边的大小和颜色-->
<stroke android:width="1dp"
    android:color="#33da33"/>
</shape>

我们接下来看一下承载滑块容易的track.xml他们同样表示两种状态,但他们是不一样的效果,因为为了突出滑动与未滑动的区别,所以背景色不一样,代码如下:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@drawable/open_track"/>
    <item android:drawable="@drawable/shut_track"/>

</selector>

我们看一个open_track.xml文件效果和代码

uniapp智能家居APP android智能家居_java_04

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

        <!-- 高度30   此处设置宽度无效-->
        <size android:height="40dp"/>
        <!-- 圆角弧度 15 -->
        <corners android:radius="15dp"/>
        <!-- 变化率  定义从左到右的颜色不变 -->
        <gradient
            android:endColor="#66ff33"
            android:startColor="#66ff33" />
</shape>

看一下未滑动时的状态布局文件shut_track.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <size android:height="40dp" android:width="40dp"/>
    <corners android:radius="20dp"/>
    <gradient android:startColor="#eeeeee"
        android:endColor="#eeeeee"/>
    <stroke android:width="1dp"
            android:color="#666666"/>
</shape>

看一下整体welcome.xml布局文件的代码如下:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/background1">

    <ImageView
        android:id="@+id/image"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:src="@drawable/home"
        android:layout_gravity="center"
        android:layout_marginTop="100dp"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="智能家居"
        android:textSize="30sp"
        android:layout_gravity="center"
        android:layout_marginLeft="0dp"
        android:textColor="#00ffcc"
        android:layout_marginTop="20dp"
        />
    <Switch
        android:id="@+id/Open"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:thumb="@drawable/thumb"
        android:track="@drawable/track"
        android:layout_gravity="center"
        android:layout_marginTop="50dp"
        android:layout_marginRight="15dp"/>
</LinearLayout>

然后分析一下Welcome.java代码
代码组成也比较简单,主要是在标题栏添加添加一个back键,并设置此键的功能为返回桌面(这种方式并为杀死进程,只是退出到界面,一个finish()方法也仅仅结束当前页,如果栈里面存在多个实例,并不会杀死进程,只会反复在几个页面跳转,杀死进程可以使用广播的方式,此处略过)。然后就是声明Switch控件,并对他进行监听,然后进行一个判断,如果滑动了就跳转到登陆界面

public class Welcome extends AppCompatActivity {
    private Switch Open;
    private ImageView imageView;
    private List<Activity> list = new ArrayList<>();
    private  ExitAllProcess exit = new ExitAllProcess();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcom);

       // exit.addActivity(this);

//        imageView = findViewById(R.id.image);
//        Intent intent = getIntent();
//        Bundle bundle = intent.getExtras();
//        int view = bundle.getInt("Customview");
//        imageView.setImageResource(view);
        SetTitle();

        Open = findViewById(R.id.Open);

        Open.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked){
                    Intent intent = new Intent(Welcome.this,Login.class);
                    startActivity(intent);
                }
            }
        });
    }
    private void SetTitle() {
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeButtonEnabled(true);
        }
    }
    @Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()){
            case android.R.id.home:
                Intent MyIntent = new Intent(Intent.ACTION_MAIN);
                MyIntent.addCategory(Intent.CATEGORY_HOME);
                startActivity(MyIntent);
                finish();
                break;
        }
        return super.onOptionsItemSelected(item);
    }
}

登陆界面

界面如下:

login.xml布局文件代码如下:

布局较为简单,那个小眼睛就显示密码和隐藏密码,然后采用一些自定义Drawable,把EditText弄的圆一点,美观一点,其余没什么。

那我们现在看一下Login.java里面的代码:
其中一部分登陆是登陆新大陆云平台的方法,因为底层硬件获取的数据都是上传到云平台的,但是为了方便看效果,后面均以获取随机数据为基准。
其中的 SetTitle();方法和Welcome界面一样,添加一个back键,但是触发事件不一样,这个的功能是返回到Welcome界面。然后就是小眼睛那部分代码,实际就是给Imageview注册一个点击事件,然后点击之后换一张图片,然后利用EditText的属性将密码隐藏和显示,新大陆那一块可以省略,然后点击登陆跳转到导航界面。

//隐藏密码
 PassWord.setTransformationMethod(PasswordTransformationMethod.getInstance());
 //显示密码
 PassWord.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
public class Login extends AppCompatActivity {
    private Button Login;
    private EditText UserName,PassWord;
    private ImageView NotSeePassWord;
    private boolean Smalleye = true;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login2);
        InitView();
        OnClick();
        SetTitle();
       NotSeePassWord.setImageResource(R.drawable.closeeye);//设置初始化密码为不可见图片

    }
    private void InitView(){
        Login = findViewById(R.id.login);
        UserName = findViewById(R.id.username);
        PassWord = findViewById(R.id.password);
       // SeeThePassWord = findViewById(R.id.seethepassword);
        NotSeePassWord = findViewById(R.id.notseethepassword);
    }
    private void OnClick(){
        OnClick onClick = new OnClick();
        Login.setOnClickListener(onClick);
        //SeeThePassWord.setOnClickListener(onClick);
        NotSeePassWord.setOnClickListener(onClick);
    }


    private class OnClick implements View.OnClickListener{

        @Override
        public void onClick(View v) {
            switch (v.getId()){
                case R.id.login:
                    SignIn();
                   break;
                case R.id.notseethepassword:
                    if (Smalleye == true)
                    {
                        SeeThePassWordMethod();
                        Smalleye = !Smalleye;
                    }else {
                        NotSeeThePassWordMethod();
                        Smalleye = !Smalleye;
                    }
                    break;
            }
        }
    }

    private void NotSeeThePassWordMethod(){
        NotSeePassWord.setImageResource(R.drawable.closeeye);
        PassWord.setTransformationMethod(PasswordTransformationMethod.getInstance());

    }
    private void SeeThePassWordMethod(){
        NotSeePassWord.setImageResource(R.drawable.openeye);
      PassWord.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
    }
    private void SignIn(){
        String platformAddress = NewloadParameter.IP_DEFAULT_VALUE;  //网址加端口号
        String LoginUserName = UserName.getText().toString();
        String LoginPassWord = PassWord.getText().toString();

        if (TextUtils.isEmpty(platformAddress)){
            Toast.makeText(this,"请配置新大陆云平台信息",Toast.LENGTH_SHORT).show();
            return;
        }
        if (TextUtils.isEmpty(LoginUserName) || TextUtils.isEmpty(LoginPassWord)){

        if (!LoginPassWord.equals("123456")){

                BaseResponseEntity<User> baseResponseEntity = response.body(); //获取请求
                if (baseResponseEntity != null){
                    //获取访问令牌
                    String accestoken = baseResponseEntity.getResultObj().getAccessToken();
                    Intent intent = new Intent(Login.this,ChooseInterface.class);
                    Bundle bundle = new Bundle();
                    bundle.putString("accestoken",accestoken);

                    startActivity(intent);
                    finish();
                }
            }
        });
  }
    private void SetTitle() {
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {

}

导航界面

效果图如下:

代码较为简单,并不复杂,同样是使用自定义Drawable优化界面,然后一个搜索栏,这个搜索栏也是比较low的,并没有去自定义view,而是搜索那几个关键字,然后给那个图片这个一个点击事件,然后进行页面跳转。

看一下java部分代码:
SetTitle();和前面一样,此处省略,这个比较简单,就是几个页面的跳转,此处也省略。

public class ChooseInterface extends AppCompatActivity {
    private LinearLayout TmpView,HumView,SmokeView,InfraredView;
    private EditText SearchBar;
    private String SearchBarContent;

               Intent intent = new Intent(ChooseInterface.this,Login.class);
               startActivity(intent);
                break;
        }

                    break;
                case R.id.InfraredBox:
                    intent = new Intent(ChooseInterface.this,InfraredInterface.class);
                    break;

            }
            startActivity(intent);
        }
    }
    private void setListener(){
        OnClick onClick = new OnClick();
        TmpView.setOnClickListener(onClick);
        HumView.setOnClickListener(onClick);

    private void InitView(){

        HumView = findViewById(R.id.HumBox);
        SmokeView = findViewById(R.id.SmokeBox);

            @Override
            public void onClick(View v) {
                Intent intent = null;
                SearchBarContent = SearchBar.getText().toString().trim();
                switch (SearchBarContent){
                    case "温度":
                        intent = new Intent(ChooseInterface.this,TmpInterface.class);
                        break;
                    case "湿度":
                        intent = new Intent(ChooseInterface.this,HumInterface.class);
                        break;

                startActivity(intent);
            }
        });
    }
}

温度界面

先看一下效果:

两个Switch,一个控制风扇的旋转,一个控制灯泡的亮和灭,下面是一个SeekBar,下面那个SeekBar是自定义过的,和Switch一样改一下滑块和背景,根据滑动的大小,表示一个温度值,温度大小控制风扇和灯,风扇的旋转是采用动画,在java部分详细介绍。

看一下java部分:

其余比较简单,我们就看一下InitAnimation();部分:

逐句解释:

第一句获取资源文件,有两个参数,第一个是Context上下文,第二个是图片要变化的文件,一般创建一个anim包,然后里面存放一些文件,比如我这里建了一个rotate文件,里面主要写了从那个角度开始旋转,旋转模式等

第二句:设置持续时间

第三句:设置重复模式(“restart” =从头开始 或者 “reverse”=从末尾开始)

第四句:是否当旋转完之后,继续从当前方向旋转

下面为插值器,因为我要的效果并不是很好,所以并没有使用。

private void InitAnimation(){
        animation = AnimationUtils.loadAnimation(TmpInterface.this,R.anim.rotate);
        animation.setDuration(1000);
        //animation.setRepeatCount(-1); //无限旋转
        animation.setRepeatMode(1);
        animation.setFillAfter(true);
//            CycleInterpolator interpolator = new CycleInterpolator(1);
//            animation.setInterpolator(interpolator);

湿度界面

效果如下:

此界面比较简单,一个RecyclerView控件,然后一个Button跳转到地图界面,关于地图界面请参考前面文章百度地图跳转链接

java部分:
将俩部分吧,一个是Handler部分,一个是自定义view部分
Handler部分:实现Handler.Callback接口,主要工作流程是,延迟一会,然后这个进度值,把进度值通过线程方式将这个进度值发过去,然后自定义view就把自己的进度值设置为自己的进度值。
自定义view部分:
主要是先画一个背景圆,然后在上面画一层描边(圆弧),这个是通过进度值的大小来改变的,然后关于在values下创建一个attrs.xml文件(名字不可改),然后设置圆的颜色,大小等。
