以编程方式将boxBackgroundMode设置为TextInputLayout [英] Programmatically set boxBackgroundMode to TextInputLayout
问题描述
我只是从 com.android.support:design 迁移到 com.google.android.material .
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.1.0'
我无法以编程方式将boxBackgroundMode设置为 TextInputLayout 的概述.
I have the troubles with set up boxBackgroundMode as an outline for TextInputLayout programmatically.
val textInputLayout = TextInputLayout(this)
textInputLayout.addView(EditText(this))
textInputLayout.boxBackgroundMode = TextInputLayout.BOX_BACKGROUND_OUTLINE
textInputLayout.boxStrokeColor = Color.BLACK
textInputLayout.boxBackgroundColor = Color.BLACK
textInputLayout.setBoxCornerRadii(23f,23f,23f,23f)
someParentLayout.addView(textInputLayout)
与此同时,我没有遇到 com.android.support:design 这样的问题.有人可以建议如何解决或说出 com.google.android.material 无效的原因.
At the same time, I hadn't such problems with com.android.support:design. Can someone suggest how to resolve or tell why for com.google.android.material it doesn't work.
P.S.它通过在xml中定义 style ="@ style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
来工作,但我需要以编程方式完成
P.S. It works by defining style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
in xml but i need to do it programmatically
推荐答案
而不是:
textInputLayout.addView(EditText(this))
执行:
val editText = EditText(this)
editText.background = null
textInputLayout.addView(editText)
// Alternatively `textInputLayout.addView(EditText(this).apply { background = null })`
为什么?
摘录自 TextInputLayout
来源:
private boolean shouldUseEditTextBackgroundForBoxBackground() {
// When the text field's EditText's background is null, use the EditText's background for the
// box background.
return editText != null
&& boxBackground != null
&& editText.getBackground() == null // <-- by default EditText has background
&& boxBackgroundMode != BOX_BACKGROUND_NONE;
}
