Want to change the focused hint Edittext colour but it is not changing. What's the matter ? Have used all the attributes in the edit Text theme but yet it's not changing.I have changed the parent theme from MaterialComponents to App Compat , is it becoz of that ?
This is my themes.xml file.

Firstly, I would start using the Material Design library in order to be up to date.
So I would add in my build.gradle (app) :
implementation 'com.google.android.material:material:1.5.0'
Then your style should look something like this:
<style name="Theme.QuizApp" parent="Theme.MaterialComponents.DayNight">
<!-- Primary brand color. -->
<item name="colorPrimary">@color/purple_500</item>
<item name="colorPrimaryVariant">@color/purple_700</item>
<item name="colorOnPrimary">@color/white</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>
<item name="colorOnSecondary">@color/black</item>
<!-- Status bar color. -->
<item name="android:windowFullscreen">true</item>
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<item name="textAppearanceSubtitle1">@style/TextAppearance.App.test</item>
<!-- Customize your theme here. -->
</style>
<style name="TextAppearance.App.test" parent="TextAppearance.MaterialComponents.Subtitle1">
<item name="hintTextColor">@color/purple_gray</item>
<item name="colorControlNormal">@color/purple_gray</item>
<item name="colorControlActivated">@color/purple_gray</item>
<item name="colorControlHighlight">@color/purple_gray</item>
<item name="android:textColorHint">@color/purple_gray</item>
<item name="boxStrokeErrorColor">@color/purple_gray</item>
</style>
Don't know how your design should look like in the XML so I just left the remaining attributes as it was in the style.
and your MainActivity should become:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val btn_start: Button = findViewById(R.id.btn_start)
val et_name: TextInputLayout = findViewById(R.id.et_name)
btn_start.setOnClickListener {
if (et_name.editText?.editableText.isNullOrEmpty()) {
et_name.setError("")
Toast.makeText(this, "Enter name", Toast.LENGTH_LONG).show()
}else{
val intent = Intent(this,QuizQuestionActivity::class.java)
intent.putExtra(Constants.USER_NAME,et_name.text.toString())
startActivity(intent)
}
}
}
}
Lastly, in your activity layout you will use that style we created (You will have to adjust that on your project):
<com.google.android.material.textfield.TextInputLayout
android:id="@ id/et_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Default"
style="@style/TextAppearance.App.test"
android:layout_margin="10dp">
<com.google.android.material.textfield.TextInputEditText
android:id="@ id/default_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
/>
</com.google.android.material.textfield.TextInputLayout>
Let me know if it worked, In my small test project it looks good :)
My small suggestions in general are:
- Do not to use findViewById since it is not good for performance for the app if you get in the future a lot of views inside your XML. I would suggest you to use viewBinding or DataBinding.
- Try to add the same amount of spaces between your code so that it looks cleaner
- Try to extract your Strings, dimensions into xml so that you can re-use them here you can find an article about it https://suragch.medium.com/using-dimens-xml-in-android-10dec2fe485c and one for strings https://riptutorial.com/android/example/13829/working-with-strings-xml-file
