以下为整个程序的操作流程,因为不能上传太大文件,所以画质比较模糊。
启动应用界面
先来看一下启动界面:效果图如下:
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
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
<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。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
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(){

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)){
Toast.makeText(this,"账号或者密码不能为空",Toast.LENGTH_SHORT).show();
return;
}
if (!LoginPassWord.equals("123456")){

return;
}
if (!LoginUserName.equals("admin")){
Toast.makeText(this,"账号或者密码错误",Toast.LENGTH_SHORT).show();
return;
}
if (LoginPassWord.equals("123456") && LoginUserName.equals("admin")){
Intent intent = new Intent(Login.this,ChooseInterface.class);
startActivity(intent);
}
NetWorkBusiness netWorkBusiness = new NetWorkBusiness("",platformAddress);
netWorkBusiness.signIn(new SignIn(LoginUserName, LoginPassWord), new NCallBack<BaseResponseEntity<User>>(getApplicationContext()) {
@Override
protected void onResponse(BaseResponseEntity<User> response) {
}
@Override
public void onResponse(Call<BaseResponseEntity<User>> call, Response<BaseResponseEntity<User>> response) {
super.onResponse(call, response);
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);
intent.putExtras(bundle); // 传递令牌
startActivity(intent);
finish();
}
}
});
}
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 intent = new Intent(Login.this, Welcome.class);
startActivity(intent);
break;
}
return super.onOptionsItemSelected(item);
}
}
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。
布局文件代码如下:

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;
private ImageView SearchImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_choose_interface);
InitView();

SearchContent();
SetTitle();
}
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:

}
}
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);
}
public class TmpInterface extends AppCompatActivity {
private TextView TmpValue;
private SeekBar seekBar;
private Switch ControlFan,ControlLamp;
private ImageView Fan,CloseLamp,OpenLamp;
private Animation animation;
private static int size;
private Button Back;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tmp_interface);
SetTitle();
InitView();
InitAnimation();
seekBar.setMax(50);//设置最大值
seekBar.setProgress(0);//设置当前值
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
size = progress;
TmpValue.setText("温度: "+size+"℃");
if (size > 30){
Fan.startAnimation(animation);
}else {
Fan.clearAnimation();
}
if (size < 15){
OpenLamp.setVisibility(View.VISIBLE);
CloseLamp.setVisibility(View.INVISIBLE);
}else {
OpenLamp.setVisibility(View.INVISIBLE);
CloseLamp.setVisibility(View.VISIBLE);
}
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
ControlFan.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (ControlFan.isChecked()){
Fan.startAnimation(animation);
}else {
Fan.clearAnimation();
}
}
});
ControlLamp.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (ControlLamp.isChecked()){
OpenLamp.setVisibility(View.VISIBLE);
CloseLamp.setVisibility(View.INVISIBLE);
}else {
OpenLamp.setVisibility(View.INVISIBLE);
CloseLamp.setVisibility(View.VISIBLE);
}
}
});
}
//设置标题栏返回按钮
private void SetTitle(){
ActionBar actionBar = getSupportActionBar();
if (actionBar != null){
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
}
private void InitView(){
seekBar = findViewById(R.id.CustomSeekBar);
TmpValue = findViewById(R.id.TmpText);
ControlFan = findViewById(R.id.FansSwitch);
ControlLamp = findViewById(R.id.LampSwitch);
CloseLamp = findViewById(R.id.ShutLamp);
OpenLamp = findViewById(R.id.OpenLamp);
Fan = findViewById(R.id.fans);
Back = findViewById(R.id.back);
}
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);
}
// @Override
// public boolean onCreateOptionsMenu(Menu menu) {
// MenuInflater inflater = getMenuInflater();
// inflater.inflate(R.menu.test_menu, menu);
// return super.onCreateOptionsMenu(menu);
// }
//对Menu中菜单中子项进行控制
@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()){
case android.R.id.home:
Intent intent = new Intent(TmpInterface.this,ChooseInterface.class);
startActivity(intent);
break;
}
return super.onOptionsItemSelected(item);
}
}
湿度界面

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。
