无法将子视图传播到其父线性布局的两侧

Question

I want to create a layout with 2 views inside.

1) A GroupView with a textView to the left

2) A imageView to the right

There is a minimal gap between them so if the textView is too long, it truncates its content, but the image is never shrinked.

Here is my try:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

  <myTextView
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/my_text"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center_vertical|left" />


  <ImageView
      android:id="@+id/my_image"
      android:layout_width="18dp"
      android:layout_height="18dp"
      android:layout_marginTop="@dimen/my_margin_vertical"
      android:layout_marginBottom="@dimen/my_margin_vertical"
      android:layout_marginEnd="@dimen/my_margin_end"
      android:layout_marginRight="@dimen/my_margin_end"
      android:layout_gravity="center_vertical|right"
      app:srcCompat="@drawable/my_color_18_vd" />
</LinearLayout>

but the outcome doesn't push the children views to the side, nor keeps the gap between them in favor to the image.

How can i fix this?

Answer 1

You can fix it by setting weight to your textview

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

  <myTextView
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/my_text"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
     android:layout_weight="1"
 android:layout_marginEnd="10dp"
      android:layout_gravity="center_vertical|left" />


  <ImageView
      android:id="@+id/my_image"
      android:layout_width="18dp"
      android:layout_height="18dp"
      android:layout_marginTop="@dimen/my_margin_vertical"
      android:layout_marginBottom="@dimen/my_margin_vertical"
      android:layout_marginEnd="@dimen/my_margin_end"
      android:layout_marginRight="@dimen/my_margin_end"
      android:layout_gravity="center_vertical|right"
      app:srcCompat="@drawable/my_color_18_vd" />
</LinearLayout>
