//TextView點(diǎn)擊監(jiān)聽 兩種方式
 
//①
TextView.setOnClickListener {//這里寫實(shí)現(xiàn)的功能}
 
//②
TextView.setOnClickListener(object :OnClickListener{ 
override fun onClick(v: View?) {//這里寫實(shí)現(xiàn)的功能}
})
 
//TextView長(zhǎng)按監(jiān)聽 兩種方式
//①
TextView.setOnLongClickListener { 
//這里寫實(shí)現(xiàn)的功能 
true}
 
//②
TextView..setOnLongClickListener(object : OnLongClickListener {
override fun onLongClick(v: View?): Boolean {
//這里寫實(shí)現(xiàn)功能
return true
}
})

//EditText點(diǎn)擊和長(zhǎng)按監(jiān)聽 同TextView寫法一樣。下面寫一個(gè)監(jiān)聽輸入變化的方法 兩種
//①、當(dāng)前頁(yè)，繼承TextWatcher【例如：class XXXActivity : BaseActivity(), TextWatcher】
 
EditText.addTextChangedListener(this)//監(jiān)聽當(dāng)前this，然后重寫三個(gè)方法（輸入后，輸入前，輸入文字產(chǎn)生變化）
 override fun afterTextChanged(s: Editable?) {
  //輸入后的監(jiān)聽
 }
 
 override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
  //輸入后的監(jiān)聽
 }
 
 override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
  //輸入文字產(chǎn)生變化的監(jiān)聽
 }
 
//②、另一種寫法，直接監(jiān)聽
EditText.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(s: Editable?) {//輸入后的監(jiān)聽}
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {//輸入后的監(jiān)聽}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {//輸入文字產(chǎn)生變化的監(jiān)聽}
})
