android蓝牙遥控车
写了上一篇的，就一不做，二不休的把今天才完成的自制的蓝牙遥控车吧，
咱分两步走第一部分是Android 方面的，第二是硬件Zigbee方面的。
先说Android方面的，
上源代码吧：
一、Android部分
我的代码运行顺序是先是WelcomActivity，过两秒后然后进入MainActivity,在这里配对成功后进入CMDActivity
1.1、布局方面的代码，为了美观把平常写的UI美化了一下。
1.11、activity_welcome.xml
对应的java
package com.example.hejingzhou.bluetoothtoydemo;
import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Window;
public class WelcomeActivity extends AppCompatActivity {
private Handler handler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_welcome);
handler = new Handler();
handler.postDelayed(newRun,3000);
}
private Runnable newRun = new Runnable() {
@Override
public void run() {
startActivity(new Intent(WelcomeActivity.this,MainActivity.class));
finish();
}
};
}
//***************//**************//**********//**************//*****************//*****************//****************//******************//****************//
1.12、activity_main
上边这个布局所用到的
@dimen
写到@drawable文件夹内是针对Button的圆角处理的
详情是这样的

因为硬件不够只做了车的前进，和控制LED小灯。。。。。
看效果：
三秒后。。。。
配对成功后。。。。
