Kotiln的简单实用！

1：设置布局：setContentView(R.layout.activity_color)

2：设置字体,颜色：

tv.text=resources.getText(R.string.tv1)

tv.setTextColor(resources.getColor(R.color.tvs))

3：设置字体,颜色：

调用方法示例：

packagecom.example.administrator.kotiln

importandroid.support.v7.app.AppCompatActivity

importandroid.os.Bundle

importcom.example.administrator.kotiln.utils.ToastUtils

importkotlinx.android.synthetic.main.activity_second.*

importkotlinx.android.synthetic.main.activity_seconds.*

classSecondActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {

super.onCreate(savedInstanceState)

setContentView(R.layout.activity_second)

tv.text=resources.getText(R.string.tv1)

tv.setTextColor(resources.getColor(R.color.tvs))

initView()

}

private fun initView() {

TODO("not implemented")//To change body of created functions use File | Settings | File Templates.

}

// private fun initView() {

// ToastUtils.showToast(this,"22222222222")

// }

}

切记写完initView（）方法，生成如下图方法initView（），一定要删除TODO("not implemented")，否则报错！

4：点击事件(上下文申明this@SecondActivity)

bt.setOnClickListener{

varintent = Intent(this@SecondActivity,OkGoActivity::class.java)

startActivity(intent)

}

5：网络请求的格式

/**

*登录请求网络

*

*@param

*@param

*/

private funokgo() {

valurl =" http://tangwu.com/app/login.php"

Share.d("网络请求"+ url)

valtel ="18737192723"

valpassword ="123456"

OkGo.post<String>(url)

.tag(this)

.retryCount(3)

.cacheKey("login")

.cacheMode(CacheMode.DEFAULT)

.params("username",tel)

.params("password",password)

.execute(object: StringCallback() {

override fun onSuccess(response: com.lzy.okgo.model.Response<String>) {

Share.d("新网络请求"+ response.body())

valresult = Json.parse_message(response.body())

if(result.isState&& result !=null) {

//Gson解析

valgson = Gson()

login_data= gson.fromJson<Login_Data>(response.body(), object : TypeToken<Login_Data>() {

}.type)

if(login_data!!.ret=="ok") {

handler.sendEmptyMessage(1)

}else if(login_data!!.ret=="err") {

handler.sendEmptyMessage(2)

}

}else{

ToastUtils.showToast(this@OkGoActivity,result.message)

}

}

override fun onError(response: com.lzy.okgo.model.Response<String>) {

super.onError(response)

Share.d("错误："+ response.body())

handler.sendEmptyMessage(0)

}

})

}

private valhandler=object: Handler() {

override fun handleMessage(msg: Message) {

super.handleMessage(msg)

when(msg.what) {

0-> ToastUtils.showToast(this@OkGoActivity,resources.getString(R.string.err_alert))

1->if(login_data!!.data.toString().length>0&&login_data!!.data!=null) {

Share.d("token"+login_data!!.data.user_token)

SPUtils.put(this@OkGoActivity,"token",login_data!!.data.user_token)

Share.d("取token"+ SPUtils.get(this@OkGoActivity,"token","")!!)

// Share.d("status" + status);

//ToastUtil.show(LoginActivity.this, login_data.getMsg());

ToastUtils.showToast(this@OkGoActivity,"登录成功")

finish()

}

2-> {

}

}

}

}

5：开启子线程

Thread(Runnable{

}).start()
