先说一下这篇文章里面的内容:TCP 客户端, 自定义对话框, 自定义按钮, ProgressBar竖直显示, 重力感应传感器,手机返回键新开启界面的问题(返回上次的界面),数据保存

软件的通信是配合

http://www.cnblogs.com/yangfengwu/p/7625608.html 用ESP8266+android,制作自己的WIFI小车(ESP8266篇)

软件的第一个界面就一个按钮点击按钮弹出一个自定义的对话框连接的时候连接上

其实一开始想多加一些功能,,不过后来想了想复杂了反而不利于学习.........我会从一开始做到结束都写清楚,如果有大神看到哪地方不合理请指教哈,,,,,

好现在开始做APP

一路Next就行...

您会发现自己的按钮是圆边的

其实是自己自定义了一些参数

新建一个文件夹存储咱们自定义的一些东西

对了为什么名字是drawable

其实是官方提供的,,

http://www.android-doc.com/guide/topics/resources/drawable-resource.html#StateList

然后呢各个参数后面都有具体解释

有些小伙伴一看....英文的............大哥下一个有道翻译或者别的翻译软件翻译一下...................

可以自己搜索自己想要的

好像这些外形啦背景什么的都在

授人予鱼,也要授人予渔;

首先定义一下外形

方形

然后呢描一下边框,,,显得是一个按钮

其实可以官方解释

然后定义一下按钮现在显示的颜色

好现在让它的四个角变成圆角,,,对于我这个学机械的而言在solidworks里面应该叫做倒角,,,,有没有学机械的看到这篇文章哈...

记得曾经遇到一个人和我正好相反,,我是报的机械专业,自学的电气,,,,,,而另一个人是报的电气却喜欢机械........兴趣.........

好啦

拖一个按钮过来,放到中心.....您也可以在布局文件里面自己写哈......我是怎样方便怎样弄,,我用的是相对布局

保存一下现在看效果

好现在再定义一个按钮按下时的外表文件

privateOnTouchListener buttonconnect1Touch =newOnTouchListener() {

@Overridepublicboolean onTouch(View v, MotionEventevent) {//TODO Auto-generated method stubif(event.getAction()==MotionEvent.ACTION_DOWN) {

buttonconnect1.setBackgroundResource(R.drawable.buttondown);

}if(event.getAction()==MotionEvent.ACTION_UP) {

buttonconnect1.setBackgroundResource(R.drawable.butonup);

}returnfalse;

}

};

package com.wificardemo;

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.MotionEvent;

import android.view.View;

import android.view.View.OnTouchListener;

import android.widget.Button;publicclassMainActivity extends Activity {

Button buttonconnect1;

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

buttonconnect1= (Button) findViewById(R.id.button11);//获取按钮buttonconnect1.setOnTouchListener(buttonconnect1Touch);//按钮的触摸事件}privateOnTouchListener buttonconnect1Touch =newOnTouchListener() {

@Overridepublicboolean onTouch(View v, MotionEventevent) {//TODO Auto-generated method stubif(event.getAction()==MotionEvent.ACTION_DOWN) {

buttonconnect1.setBackgroundResource(R.drawable.buttondown);

}if(event.getAction()==MotionEvent.ACTION_UP) {

buttonconnect1.setBackgroundResource(R.drawable.butonup);

}returnfalse;

}

};

@Overridepublicboolean onCreateOptionsMenu(Menu menu) {//Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);returntrue;

}

@Overridepublicboolean onOptionsItemSelected(MenuItem item) {//Handle action bar item clicks here. The action bar will//automatically handle clicks on the Home/Up button, so long//as you specify a parent activity in AndroidManifest.xml.intid =item.getItemId();if(id ==R.id.action_settings) {returntrue;

}returnsuper.onOptionsItemSelected(item);

}

现在编译一下运行到手机看一下

我是直接用的自己的手机,,没有仿真,,现在我的电脑用仿真可是不得了......

平时的状态按下后

自己看着改改大小和显示

咱们现在要做的是

其实这个是自己自定义的一个界面

对了设置一下主题风格...

感觉这种风格挺好的

图片可以在我源码里面找,也可以自己弄自己的

对了,,,,位置还有名字什么的自己看着修改哈

整体界面呢,,,

android:background="@android:color/white"android:id="@+id/textView22"android:layout_width="wrap_content"android:layout_height="2dip"android:layout_alignParentLeft="true"android:layout_alignParentRight="true"android:layout_below="@+id/imageView21"android:layout_marginTop="15dp"/>

android:id="@+id/textView21"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="8dp"android:layout_marginLeft="19dp"android:layout_toRightOf="@+id/imageView21"android:text="连接"android:textAppearance="?android:attr/textAppearanceLarge"android:textColor="@android:color/white"/>

android:id="@+id/imageView21"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="10dp"android:layout_marginTop="14dp"android:src="@drawable/image1"/>

android:id="@+id/textView24"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignBaseline="@+id/editText22"android:layout_alignBottom="@+id/editText22"android:layout_alignParentLeft="true"android:text="端口号:"/>

android:id="@+id/editText22"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/editText21"android:layout_below="@+id/editText21"android:layout_marginTop="10dp"android:ems="10"android:text="8080"/>

android:id="@+id/button21"android:layout_width="80dp"android:layout_height="40dp"android:layout_alignParentRight="true"android:layout_below="@+id/editText22"android:layout_marginRight="10dp"android:background="@drawable/butonup"android:text="连接"/>

android:id="@+id/progressBar21"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignTop="@+id/textView23"android:layout_centerHorizontal="true"/>

好了现在点击主界面的按钮把这个界面当做提示框显示出来

package com.wificardemo;

import android.app.Activity;

import android.app.AlertDialog;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.MotionEvent;

import android.view.View;

import android.widget.EditText;

import android.widget.ProgressBar;

import android.widget.TextView;publicclassMainActivity extends Activity {

Button buttonconnect1;

buttonconnect1= (Button) findViewById(R.id.button11);//获取按钮buttonconnect1.setOnTouchListener(buttonconnect1Touch);//按钮的触摸事件/**对话框相关**/AlertDialog21=newAlertDialog.Builder (MainActivity.this).create();

View1= View.inflate(MainActivity.this, R.layout.dialog,null);

AlertDialog21.setView(View1);//设置显示内容为自定义的界面connectbutton21 = (Button) View1.findViewById(R.id.button21);//连接服务器按钮cancelbutton22 = (Button) View1.findViewById(R.id.Button22);//取消按钮progressBar21 = (ProgressBar) View1.findViewById(R.id.progressBar21);//进度条progressBar21.setVisibility(-1);//进度条不显示iPEditText = (EditText)View1.findViewById(R.id.editText21);//IP地址portEditText = (EditText)View1.findViewById(R.id.editText22);//端口号titleEditText = (TextView) View1.findViewById(R.id.textView21);//"连接"}/***

* 主界面连接服务器按钮*/privateOnTouchListener buttonconnect1Touch =newOnTouchListener() {

@Overridepublicboolean onTouch(View v, MotionEventevent) {//TODO Auto-generated method stubif(event.getAction()==MotionEvent.ACTION_DOWN) {

buttonconnect1.setBackgroundResource(R.drawable.buttondown);

}if(event.getAction()==MotionEvent.ACTION_UP) {

buttonconnect1.setBackgroundResource(R.drawable.butonup);

}returnfalse;

}

};

}

现在呢就缺少显示了...

我们在主按钮的点击事件中调用显示函数

package com.wificardemo;

import android.app.Activity;

import android.app.AlertDialog;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.MotionEvent;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.View.OnTouchListener;

import android.widget.Button;

import android.widget.TextView;publicclassMainActivity extends Activity {

Button buttonconnect1;

* 主按钮点击事件*/privateOnClickListener buttonconnect1Click =newOnClickListener() {

@OverridepublicvoidonClick(View v) {//TODO Auto-generated method stubAlertDialog21.show();

}

};/***

* 主界面连接服务器按钮背景改变*/privateOnTouchListener buttonconnect1Touch =newOnTouchListener() {

@Overridepublicboolean onTouch(View v, MotionEventevent) {//TODO Auto-generated method stubif(event.getAction()==MotionEvent.ACTION_DOWN) {

buttonconnect1.setBackgroundResource(R.drawable.buttondown);

}if(event.getAction()==MotionEvent.ACTION_UP) {

buttonconnect1.setBackgroundResource(R.drawable.butonup);

}returnfalse;

}

};

}

现在安装到手机上看一下---界面还可以

做这个简单的取消事件

连接按钮呢!!我先说一下思路,,,按下连接按钮是启动一个连接任务,然后呢还要启动一个倒计时器(3S),,,控制这个连接任务执行的时间,还要显示进度条,,如果3S内连接上了,,那么在连接的后面关掉进度条,结束这个连接任务,取消定时器,关闭对话框,然后进入控制界面,,如果3S内没有连接上,也关闭连接任务,关掉进度条,同时显示连接失败.

}

现在加上权限然后连接WIFI模块测试一下哈

连接模块的无线

然后会发现

对话框消失了

因为咱们自己设置的消失

现在让它连接后打开控制界面

还是先把IP和端口号的信息做成能够保存的吧

咱们就用SharedPreferences

可以看一下这篇文章的介绍

http://blog.csdn.net/baidu_31093133/article/details/51476726##1

得到SharedPreferences对象

然后

那么一开始运行就要检测是不是记录了,,如果记录了就取出来记录的数据然后显示在对应的文本框中

现在做控制界面

android:background="@android:color/background_dark"android:id="@+id/textView31"android:layout_width="wrap_content"android:layout_height="2dp"android:layout_alignParentLeft="true"android:layout_alignParentRight="true"android:layout_centerVertical="true"/>

android:background="@android:color/transparent"android:id="@+id/imageButton33"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentRight="true"android:layout_centerVertical="true"android:layout_marginRight="10dp"android:src="@drawable/youzhuan"/>

android:id="@+id/checkBox31"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_centerHorizontal="true"android:layout_centerVertical="true"android:text="开重感"/>

这个ProgressBar默认是,,水平的

要改成竖直的其实就是自己写一个外观和变化的文件,然后调用,,,,,就像咱们自定义按钮样式一样

然后呢在里面加上

android:startColor="#ff9d9e9d"android:centerColor="#ff5a5d5a"android:centerY="0.75"android:endColor="#ff747674"android:angle="270"/>

android:clipOrientation="vertical"android:gravity="bottom">

android:startColor="#ffffd300"android:centerColor="#ffffb600"android:centerX="0.75"android:endColor="#ffffcb00"android:angle="90"/>

要问我你怎么知道这样写..百度的,然后从源码里面copy 过来的.........亲们也可以百度哈,,,,,现在我也只是个入门的,只不过善于去用别人的东西,,不过后期我肯定会去学习这些东西代表的含义

现在的控制的界面

布局文件

android:background="@android:color/transparent"android:id="@+id/textView31"android:layout_width="wrap_content"android:layout_height="2dp"android:layout_alignParentLeft="true"android:layout_alignParentRight="true"android:layout_centerVertical="true"/>

现在连接上以后跳转到这个界面

设置在连接上以后,跳转

对了要在

现在可以试一试

整体还好啦.....只不过中间的那个textview太明显了.....咱在代码中把他设置成透明的

下面开始做控制的代码,那些一看就懂的咱就稍微一说哈,,,

现在看重力传感器,,还是先看,这个,,因为重力传感器的数据要用这个ProgressBar显示

可以下载进去看一下

先把这个也做上

现在把手机的传感器弄上来

这是一个人介绍的感觉挺好的

}

textView35.setText(String.valueOf(Speed));//Toast.makeText(controlcar.this, Y_longitudinal+"", 500).show();runOnUiThread(newRunnable() {publicvoidrun()

{

}

});

}

};

}

直接加了一些程序下载到手机旋转手机可以看出效果

对了,,一定要加一个关掉传感器的操作.....因为一旦打开,,您不主动关掉,它就一直运行,,,,,,耗电哈,,耗电,,耗电,,,,

代码越来越多,,有什么办法把以前的折叠

整体就是程序一开始启动发送数据任务,,,

发送数据的方式可以轻松的看出来

关于为什么需要&0xff,可以看这篇文章

http://bbs.csdn.net/topics/260061974

现在呢!!把MainActivity的

改为静态的,,,,

因为换到了其它界面,,,所以在其它界面这个socket是null

静态的可以避免啦..............

当然也可以在跳转界面的时候想办法把socket传过去.............

现在可以终于可以控制车了.....................

算了不演示了,,一口气写完

现在在控制界面实现这个功能,按一次提示返回主界面,,2S内连续按就返回

publicboolean onKeyDown(intkeyCode,KeyEventevent)

{if(keyCode ==KeyEvent.KEYCODE_BACK&&event.getAction() ==KeyEvent.ACTION_DOWN) {//判断间隔时间大于2秒就退出应用if((System.currentTimeMillis() - exitTime) >2000) {

Toast.makeText(getApplicationContext(),"再按一次返回连接界面",

Toast.LENGTH_SHORT).show();

exitTime=System.currentTimeMillis();

}else{

intentmain.setClass(Control.this, MainActivity.class);//跳转到控制界面Control.this.startActivity(intentmain);

}returnfalse;

}

主界面呢按返回键

/***

* 手机返回按钮*/publicboolean onKeyDown(intkeyCode,KeyEventevent)

{if(keyCode == KeyEvent.KEYCODE_BACK &&event.getAction() ==KeyEvent.ACTION_DOWN) {//判断间隔时间大于2秒就退出应用if((System.currentTimeMillis() - exitTime) >2000)

{

Toast.makeText(getApplicationContext(),"再按一次退出程序",Toast.LENGTH_SHORT).show();

exitTime=System.currentTimeMillis();

}else{try{socket.close();}catch(IOException e) {e.printStackTrace();}try{outputStream.close();}catch(IOException e) {e.printStackTrace();}try{inputStream.close();}catch(IOException e) {e.printStackTrace();}
