直播带货平台源码Android实现自定义圆形、方形输入框

直播带货平台源码Android实现自定义圆形、方形输入框的相关代码
实现思路分析：
1、使用一个LinearLayout用来填充每一个小方格，通过动态添加，实现出需要数量的输入框
2、在LinearLayout上覆盖一层大小和LinearLayout大小完全一致的EditText，用来接口输入信息，设置EditText输入背景和文字为透明，并设置不展示光标，
3、监听EditText的内容变化，和LinearLayout的内容绑定，实现每次输入都由LinearLayout的子布局展示出来

布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<LinearLayout
android:orientation="horizontal"
android:id="@+id/rvContentList"
android:gravity="center"
android:showDividers="middle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

<EditText
android:id="@+id/inputReal"
android:inputType="number"
android:background="@android:color/transparent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@android:color/transparent"/>

</RelativeLayout>

在代码中动态创建LinearLayout子布局填充，并绑定监听

private fun initContainer() {

//动态设置EditText的大小
inputReal = findViewById(R.id.inputReal)
rvContentList = findViewById(R.id.rvContentList)
inputReal.width = (dividerDrawable?.minimumWidth ?: 0 * (verifyCodeLen - 1)) + inputBoxSize * verifyCodeLen
inputReal.height = inputBoxSize
inputReal.setTextSize(TypedValue.COMPLEX_UNIT_PX, inputTextSize * 1.0F)

//禁用光标
inputReal.isCursorVisible = false
inputReal.filters = arrayOf(InputFilter.LengthFilter(verifyCodeLen))

inputTextView.clear()

//动态添加LinearLayout之间的分割线
dividerDrawable?.let {
it.setBounds(0, 0, it.minimumWidth, it.minimumHeight)
rvContentList.dividerDrawable = it
}

for (i in 0 until verifyCodeLen) {
val textView = TextView(context)
textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, inputTextSize * 1.0F)
textView.width = inputBoxSize
textView.height = inputBoxSize
textView.gravity = Gravity.CENTER
textView.isFocusable = false
textView.textColor = inputTextColor
textView.backgroundResource = itemSelector
inputTextView.add(textView)
}

inputTextView.forEach {
rvContentList.addView(it)
}
}
inputReal.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(p0: Editable?) {
setVerifyCodeInputValue(p0.toString())
if (p0.toString().length == verifyCodeLen) {
onCompleteListener?.onComplete(p0.toString())
}
}

override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
}

override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
}
})
private fun setVerifyCodeInputValue(inputText: String) {
inputTextView.forEach {
it.text = ""
it.isSelected = false
}
inputTextView.forEachIndexed { index, textView ->
if (inputText.length > index) {
textView.isSelected = true
textView.text = inputText[index].toString()
}
}
}
