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：

package com.example.administrator.kotiln

import android.support.v7.app.AppCompatActivity

import android.os.Bundle

import com.example.administrator.kotiln.utils.ToastUtils

import kotlinx.android.synthetic.main.activity_second.*

import kotlinx.android.synthetic.main.activity_seconds.*

class SecondActivity : 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 {

var intent = 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 fun okgo() {

val url = " http://tangwu.com/app/login.php"

Share.d("网络请求" + url)

val tel = "18737192723"

val password = "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())

val result = Json.parse_message(response.body())

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

//Gson解析

val gson = 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 val handler = 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()
