Tint bitmap in layer-list
For anyone else that may come across this question. This is what I did.
Setup
- Android Studio 2.3.2
Windows 10
Gradle
minSdkVersion 15
- targetSdkVersion 25
- compile 'com.android.support:appcompat-v7:25.3.1'
Test Devices
- Asus Padfone X Android v4.4.2
- Samsung Galaxy S3 Android v6.0
- Samsung Galaxy S7 Android v7.0
Layer DrawableI added android:id=@+id/bitmapID to the item containing the bitmap
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <shape android:shape="oval"> <solid android:color="#9e9e9e" /> <size android:width="45dp" android:height="45dp"/> </shape> </item> <item android:id="@+id/tintDrawableImg" android:left="5dp" android:right="5dp" android:top="5dp" android:bottom="5dp"> <bitmap android:src="@mipmap/ic_pencil" android:tint="#860000" /> </item></layer-list>Activity LayoutI added the layer drawable to an ImageView
<ImageView android:id="@+id/tintLayerTest" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/test_layer"/>MainActivityIn the onCreate() method we can locate the bitmap from the layer drawableusing findViewByID
public class MainActivity extends AppCompatActivity { ImageView iv; LayerDrawable ld; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //Declare ImageView containing LayerDrawable iv = (ImageView)findViewById(R.id.tintLayerTest); //Get LayerDrawable from ImageView ld = (LayerDrawable)iv.getDrawable(); //Get specific Drawable/Bitmap from within LayerDrawable //by ID and pass it as an independent Drawable Drawable ldDrawable = ld.findDrawableByLayerId(R.id.tintDrawableImg); //Pass your new Drawable to DrawableCompat.setTint //and define your color int DrawableCompat.setTint(ldDrawable, ContextCompat.getColor(this, R.color.colorAccent)); }}I hope this helps others that come across this question.
Try with xml drawable using bitmap tag
Save the following file xml custom_image.xml & replace your icon & tint color
<?xml version="1.0" encoding="utf-8"?> <bitmap xmlns:android="http://schemas.android.com/apk/res/android" android:src="@drawable/iv_veg" android:tint="@color/red"> </bitmap>
