I have two ListViews
(leftList, rightList). I also have one TextView
which I use as row view in both of them.
I have a rectangle drawable shape and set it as background to the TextView
.
I would like to change this shape and have rounded corners on the left.
What I tried :
GradientDrawable gradientDrawable = new GradientDrawable();
// gradientDrawable.setCornerRadius(30);
((GradientDrawable)gradientDrawable.mutate()).setCornerRadius(30);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
viewHolderPattern.digits.setBackground(gradientDrawable);
}
I have created a new layout in drawable with the right corner radius set and set that to the textView with setBackgroundRescource
but still didn't work.
The TextView that I use as items in both listViews
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/digitsTextView"
android:textSize="15dp"
android:paddingTop="7dp"
android:paddingBottom="8dp"
android:fontFamily="monospace"
android:textColor="@color/selected_items"
android:background="@drawable/digital_text_shape">
</TextView>
Shape layout digital_text_shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="1dp"
android:color="@color/orange" />
<solid android:color="@color/orange" />
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="20dp"
android:topRightRadius="0dp"
/>
<padding
android:bottom="0dp"
android:left="20dp"
android:right="0dp"
android:top="0dp" />
</shape>
Left list and Right list
<!-- Left ListView -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:id="@+id/left_listView"
android:divider="@android:color/transparent"
android:dividerHeight="0.1sp"
android:choiceMode="singleChoice"
>
</ListView>
</LinearLayout>
<!-- Right ListView -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
>
<ListView
android:id="@+id/right_listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@android:color/transparent"
android:dividerHeight="0.1sp"
android:choiceMode="singleChoice"
>
</ListView>
</LinearLayout>
Here example for how to create GradientDrawable
shape programmatically.
GradientDrawable shape = new GradientDrawable();
shape.setShape(GradientDrawable.RECTANGLE);
shape.setColor(Color.RED);
shape.setStroke(3, Color.YELLOW);
For change the radius for all corners of the gradient.
shape.setCornerRadius(15);
For Change the radius for specific corners of the gradient.
shape.setCornerRadii(new float[] { 8, 8, 8, 8, 0, 0, 0, 0 });
You can use this drawable as a background as below :
view.setBackgroundDrawable(shape);
