[TabLayout] Default tab text appearance is incorrectly setting attributes for text appearance instead of style

[geoff-powell]

Description: When updating to 1.9.0 of material, we noticed an error when taking Paparazzi snapshot tests using a TabLayout. There was a change from 1.7.0 -> 1.9.0 where defaultTabTextAppearance was used.

Expected behavior: Correctly load styles from attributes using something like this

val attrs = intArrayOf(defaultTabTextAppearance)       // The array of attributes we're interested in.
val ta = context.obtainStyledAttributes(attrs)        // Get the value referenced by the attributes in the array
val resId = ta.getResourceId(0, 0)                    // The first 0 is the index in the 'attrs' array.
ta.recycle()                                          // Don't forget that! You can also use TypedArray.use { } extensions from android KTX.
TextViewCompat.setTextAppearance(textView, resId)     // Utility method to set text appearance for all SDK versions

Source code: The code snippet which is causing this issue

class SampleTest {
  @get:Rule
  val paparazzi = Paparazzi(
    deviceConfig = DeviceConfig.PIXEL_2.copy(fontScale = accessibilityTextSize.scale),
  )

  private val context: Context by lazy { paparazzi.context.wrapWithTheme { design.provide(this) } }

  @Test
  fun default() {
    val view = TabLayout(context, null)
    println("textAppearanceButton ID: " + com.google.android.material.R.attr.textAppearanceButton)
    TextViewCompat.setTextAppearance(textView, com.google.android.material.R.attr.textAppearanceButton)

    paparazzi.snapshot(view)
  }
}

Minimal sample app repro: TBD

Android API version: 32 (via Paparazzi)

Material Library version: 1.9.0

Device: (Run via junit tests with Paparazzi)

Same problem. Also happens in version 1.8.0.

Bunch of render problems with this simple XML code:

<com.google.android.material.tabs.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Tab 1" />

    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Tab 2" />

    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Tab 3" />
</com.google.android.material.tabs.TabLayout>

Style ResourceReference{namespace=apk/res-auto, type=attr, name=textAppearanceTitleSmall} is not of type STYLE (instead attr)

java.lang.NullPointerException: Cannot invoke "android.content.res.BridgeTypedArray.setTheme(android.content.res.Resources$Theme)" because "ta" is null

Yes the version problem ; try switch to implementation "com.google.android.material:material:1.7.0"

[hamidreza-sani]

This is still an issue with build 1.11.0
