alvinhkh/TextDrawable

This light-weight library provides images with letter/text like the Gmail app. It extends the Drawable class thus can be used with existing/custom/network ImageView classes.

Download

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.alvinhkh:TextDrawable:'
	}

	dependencies {
		implementation("com.github.alvinhkh:TextDrawable:")
	}

	<dependency>
	    <groupId>com.github.alvinhkh</groupId>
	    <artifactId>TextDrawable</artifactId>
	    <version></version>
	</dependency>


                            
    libraryDependencies += "com.github.alvinhkh" % "TextDrawable" % ""


                            
    :dependencies [[com.github.alvinhkh/TextDrawable ""]]

Readme

###TextDrawable This light-weight library provides images with letter/text like the Gmail app. It extends the Drawable class thus can be used with existing/custom/network ImageView classes. Also included is a fluent interface for creating drawables and a customizable ColorGenerator.

###How to use

Import with Gradle:

repositories {
    // ...
    maven { url "https://jitpack.io" }
}

dependencies {
    compile 'com.alvinhkh:TextDrawable:c1c2b5b'
}

####1. Create simple tile:

<ImageView android:layout_width="60dp"
	       android:layout_height="60dp"
	       android:id="@+id/image_view"/>

Note: Specify width/height for the ImageView and the drawable will auto-scale to fit the size.

TextDrawable drawable = new TextDrawable.Builder()
    .setColor(Color.RED)
    .setShape(TextDrawable.SHAPE_RECT)
    .setText("A")
    .build();

ImageView image = (ImageView) findViewById(R.id.image_view);
image.setImageDrawable(drawable);

####2. Create rounded corner or circular tiles:

TextDrawable drawable1 = new TextDrawable.Builder()
    .setColor(Color.RED)
    .setRadius(2)
    .setShape(TextDrawable.SHAPE_ROUND_RECT)
    .setText("A")
    .build(); 

TextDrawable drawable2 = new TextDrawable.Builder()
    .setColor(Color.RED)
    .setShape(TextDrawable.SHAPE_ROUND)
    .setText("A")
    .build();

####3. Add border:

TextDrawable drawable = new TextDrawable.Builder()
    .setBorder(1)
    .setBolderColor(Color.BLUE)
    .setColor(Color.RED)
    .setRadius(10)
    .setShape(TextDrawable.SHAPE_ROUND_RECT)
    .setText("A")
    .build();

####4. Modify font style:

TextDrawable drawable = new TextDrawable.Builder()
    .setBold()
    .setColor(Color.RED)
    .setFont(Typeface.DEFAULT)
    .setFontSize(48) 
    .setText("A")
    .setTextColor(COLOR.BLACK) 
    .toUpperCase()
    .build()

####5. Built-in color generator:

ColorGenerator generator = ColorGenerator.MATERIAL; // or use DEFAULT
// generate random color
int color1 = generator.getRandomColor();
// generate color based on a key (same key returns the same color), useful for list/grid views
int color2 = generator.getColor("user@gmail.com")

// declare the builder object once.
TextDrawable.IBuilder builder = new TextDrawable.Builder()
    .setBorder(1) 
    .setBorderColor(Color.BLUE)
    .setShape(TextDrawable.SHAPE_ROUND);

// reuse the builder specs to create multiple drawables
TextDrawable ic1 = builder.setColor(color1).setText("A").build();
TextDrawable ic2 = builder.setColor(color2).setText("B").build();

####6. Specify the width / height:

<ImageView android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/image_view" />

Note: The ImageView could use wrap_content width/height. You could set the width/height of the drawable using code.

TextDrawable drawable = new TextDrawable.Builder()
    .setWidth(48)
    .setHeight(48)
    .setColor(Color.RED)
    .setText("A")
    .build();  

ImageView image = (ImageView) findViewById(R.id.image_view);
image.setImageDrawable(drawable);

####7. Other features:

Mix-match with other drawables. Use it in conjunction with LayerDrawable, InsetDrawable, AnimationDrawable, TransitionDrawable etc.
Compatible with other views (not just ImageView). Use it as background drawable, compound drawable for TextView, Button etc.
Use multiple letters or unicode characters to create interesting tiles.
