这两个实现之间有什么区别？

DrawableCompat.setTintMode(wrappedDrawable, Mode.SRC_ATOP);
DrawableCompat.setTint(wrappedDrawable, color);

和

drawable.setColorFilter(color, Mode.SRC_ATOP);

我无法获得带有合并根标记的布局来处理视图绑定。是否可以？

include_layout.xml：

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

    <include
        android:id="@+id/include_test"
        layout="@layout/merge_layout"/>
</FrameLayout>

合并布局.xml：

<?xml version="1.0" encoding="utf-8"?>
<merge
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/include_test">

    <TextView
        android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="A Title"/>
</merge>

override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)
  val binding = IncludeLayoutBinding.inflate(layoutInflater)
  setContentView(binding.root)
  binding.includeTest.title.text = "New Title"
}

运行时异常： java.lang.NullPointerException: Missing required view with ID: includeTest
