我有一个LinearLayout(horizontal)
里面的ScrollView
。我正在尝试以编程方式在里面添加TextView
's 和's 。Button
LinearLayout
我的代码没有错误但几乎没有故障。我ScrollView
唯一的延伸TextView
不是为了Button
's。抱歉解释不充分,也许截图有帮助:Imgur。
❒ Eve gir.
是一个Button
其余的是TextView
。
我怎样才能ScrollView
伸展和包裹我Button
的。我尝试设置fillViewPort
但没有用。
TextView
添加代码:
private fun createText(prTx: String, color: String) {
val text = TextView(this)
text.text = prTx
text.gravity = Gravity.CENTER_HORIZONTAL
text.textSize = 18F
text.setShadowLayer(5F,3F,2F,Color.BLACK)
when (color) {
"n" -> text.setTextColor(Color.WHITE)
"p" -> text.setTextColor(Color.rgb(255,182,193))
"m" -> text.setTextColor(Color.rgb(182,207,255))
"cm" -> text.setTextColor(Color.rgb(182, 242, 227))
"olay" -> {
text.setShadowLayer(5F,3F,2F,Color.rgb(100,0,166))
text.setTextColor(Color.rgb(75,0,130))
}
}
text.textAlignment = TextView.TEXT_ALIGNMENT_CENTER
text.layoutParams = LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT)
val layout = findViewById<LinearLayout>(R.id.llText)
layout.addView(text)
}
Button
添加代码
private fun createButton(prTx: String, clk: Int) {
val button = Button(this)
button.text = prTx
button.setBackgroundColor(Color.TRANSPARENT)
button.gravity = Gravity.CENTER_HORIZONTAL;
button.textSize = 18F
button.transformationMethod = null;
button.setTextColor(Color.WHITE)
button.setShadowLayer(10F,5F,5F, Color.BLACK)
button.textAlignment = TextView.TEXT_ALIGNMENT_CENTER
button.setOnClickListener {
when (clk) {
}
}
button.layoutParams = LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT)
val layout = findViewById<LinearLayout>(R.id.llText)
layout.addView(button)
}
