How to make icon the same size as text in Android?-CodePudding

I have TextView with some text and ImageView with some icon. I aligned them by baseline:

android:baselineAlignBottom="true"
app:layout_constraintBaseline_toBaselineOf="@ id/penny"

TextView has some text size, but I can't guess the height of ImageView so that the text and the icon are the same height, they are always slightly different. How I can fix it?

CodePudding user response：

You can set top and bottom of image view to top and bottom of textView respectively with height of imageView as 0dp and scaleType as fitXY.

You can try this one it might be work for you.

Make Linear layout horizontal with height as wrap_content, Take Textview with your required text size. Take image view with height as match_parent and width as wrap_content.

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Demo Text"
            android:textColor="@color/black"
            android:textSize="@dimen/_30sdp" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:src="@drawable/ic_app_logo" />

    </LinearLayout>

And for ConstraintLayout layout yu can try this as below.

set android:scaleType="fitXY"

<androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:id="@ id/tvDemoText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Demo Text"
            android:textColor="@color/black"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            android:textSize="@dimen/_35sdp" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            android:scaleType="fitXY"
            app:layout_constraintTop_toTopOf="@id/tvDemoText"
            app:layout_constraintBottom_toBottomOf="@id/tvDemoText"
            app:layout_constraintStart_toEndOf="@id/tvDemoText"
            android:src="@drawable/material_drawer_ico_menu_down" />

    </androidx.constraintlayout.widget.ConstraintLayout>
