Java android color change in xml file
I have this xml where I have already set the stroke color but sometimes I want to programmatically change the color of the drains. File name dummy.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffffff" />
<stroke
android:width="1dp"
android:color="#ff000000" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<corners
android:bottomLeftRadius="7dp"
android:bottomRightRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp" />
</shape>
I want to change color (stroke color) programmatically, how can I do that?
I am using this xml here:
<LinearLayout
android:layout_marginTop="2dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/a"
android:layout_gravity="center"
android:background="@drawable/dummy"
android:layout_marginBottom="2sp"
android:orientation="horizontal"
android:padding="5dp">
<RelativeLayout
android:id="@+id/serverStatusWrapper"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:background="@drawable/shadow_green"
android:padding="2dp">
<ImageView
android:id="@+id/serverStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:antialias="true"
android:src="@drawable/ic_settings_input_antenna_white_24dp" />
</RelativeLayout>
<RelativeLayout
android:id="@+id/locationStatusWrapper"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/shadow_red"
android:padding="2dp">
<ImageView
android:id="@+id/locationStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:antialias="true"
android:src="@drawable/ic_warning_white_24dp" />
</RelativeLayout>
</LinearLayout>

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.a);
You can change the move like
GradientDrawable drawable = (GradientDrawable)linearLayout.getBackground();
drawable.setStroke(3, Color.RED);
And you can change the color solid like
GradientDrawable drawable = (GradientDrawable)linearLayout.getBackground();
drawable.setColor(Color.RED);
Hope it helps
