windowSoftInputMode="adjustResize" 在相对布局中绝对定位的情况下似乎不起作用

Question

我的 Android 屏幕下部有一个 EditText，如图所示。由于一些项目限制，我应该只使用绝对定位。

单击 EditText 时，软键盘会隐藏 EditText，如另一幅图像所示。

我尝试将 android:windowSoftInputMode="adjustResize" 放入清单文件中（也尝试过 adjustmentPan） 它仅适用于相对定位（下面注释了 textField_layoutparams 代码），但似乎不适用于绝对定位。

甚至尝试放置 ScrollView （下面注释了代码），但它不起作用。

代码：

class MainActivity : AppCompatActivity() {

private lateinit var binding: ActivityMainBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

        val scrollView: ScrollView
        val relativeLayout: RelativeLayout
        val textField: EditText

    /*scrollView = ScrollView (this)
    scrollView.layoutParams = RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.MATCH_PARENT,
        RelativeLayout.LayoutParams.MATCH_PARENT
    )*/
    //scrollView.isFillViewport = true

    //setContentView(scrollView)

    relativeLayout = RelativeLayout(this)
    relativeLayout.layoutParams = RelativeLayout.LayoutParams (
        RelativeLayout.LayoutParams.MATCH_PARENT,
        RelativeLayout.LayoutParams.MATCH_PARENT
    )
    relativeLayout.setBackgroundColor(Color.parseColor("#0000FF"))

    //scrollView.addView(relativeLayout)
    setContentView (relativeLayout)

    textField = EditText(this)

    val textField_layoutparams: LayoutParams
    textField_layoutparams = RelativeLayout.LayoutParams (
        400,
        150
    )
    textField.setBackgroundColor(Color.parseColor("#FFFFFF"))

    //textField_layoutparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE)
    //textField_layoutparams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE)
    //textField_layoutparams.setMargins(0, 0, 0, 200)
    textField.layoutParams = textField_layoutparams
    textField.hint = "Enter Text"
    textField.x = 500F
    textField.y = 2200F

    relativeLayout.addView(textField)
}

/**
 * A native method that is implemented by the 'scrollviewpoc' native library,
 * which is packaged with this application.
 */
external fun stringFromJNI(): String

companion object {
    // Used to load the 'scrollviewpoc' library on application startup.
    init {
        System.loadLibrary("scrollviewpoc")
    }
}
}

在绝对定位的情况下有什么方法可以实现所需的行为吗？

我认为当您尝试从 Kotlin 端设置

EditText

x 和 y 时会产生该问题。

android:windowSoftInputMode="adjustResize"

中的属性

Manifest.

适用于所有Android设备，但在您的情况下，我看到您以编程方式设置X和Y的区别。

你应该尝试一下这个。我希望它对你有用

override fun onCreate(){
    // ...
    relativeLayout.addView(textField) // your last line add bellow of that code

    val rootView = findViewById<View>(android.R.id.content)

    rootView.viewTreeObserver.addOnPreDrawListener(object : ViewTreeObserver.OnPreDrawListener {
        override fun onPreDraw(): Boolean {
            val heightDiff = rootView.height - relativeLayout.height

            if (heightDiff > 100) { // Adjust this threshold according to your needs
                // Soft keyboard is shown
                val newTopMargin = 2200 - heightDiff
                textField_layoutparams.topMargin = newTopMargin
                textField.layoutParams = textField_layoutparams
            } else {
                // Soft keyboard is hidden
                textField_layoutparams.topMargin = 2200
                textField.layoutParams = textField_layoutparams
            }

            return true
        }
    })
}
