#xml

这里写自定义目录标题

例如这样的：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle">
            <corners android:radius="10dp" />
            <size
                android:width="48dp"
                android:height="48dp" />
            <solid android:color="@color/color_red" />
        </shape>
    </item>

    <item
        android:bottom="6dp"
        android:left="6dp"
        android:right="6dp"
        android:top="6dp">
        <bitmap
            android:gravity="center"
            android:src="@drawable/lingxi_ic_hang_up" />
    </item>
</layer-list>

可在代码里这样使用:

convertToBitmap(R.drawable.bg_lingxi_hang_up_view)?.let { setImageViewBitmap(R.id.image_hang_up, it)}


    private fun convertToBitmap(@DrawableRes drawableRes: Int): Bitmap? {
        try {
            // 将 Drawable 转换为 Bitmap
            val drawable = TelApplication.instance?.let { ContextCompat.getDrawable(it, drawableRes) }
            AppLog.info(TAG, "convertToBitmap drawable: $drawable")
            if (drawable != null) {
                val bitmap = Bitmap.createBitmap(
                    drawable.intrinsicWidth,
                    drawable.intrinsicHeight,
                    Bitmap.Config.ARGB_8888
                )
                val canvas = Canvas(bitmap)
                drawable.setBounds(0, 0, canvas.width, canvas.height)
                drawable.draw(canvas)
                AppLog.info(TAG, "convertToBitmap bitmap: $bitmap")
                return bitmap
            }
        } catch (e: Exception) {
            e.printStackTrace()
            AppLog.error(TAG, "convertToBitmap", e)
        }

        AppLog.info(TAG, "convertToBitmap null")
        return null
    }
