How to make a circular image view

Question

I trying to make a circular image view in my Register class. I tried many solutions but none of the solutions are worked for me. Can someone help me to figuring out the problem ? Thanks.

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.seng.healthyapp"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'de.hdodenhof:circleimageview:2.1.0'
    testCompile 'junit:junit:4.12'
    compile 'com.google.android.gms:play-services-location:9.2.0'

Answer 1

this will make a bitmap rounded, i never had problems with it, when i was tring to achieve this i also tried the circular imageview but i found this to be more easy to use

Bitmap book = BitmapFactory.decodeResource(getResources(),R.drawable.book);

imageView.setImageBitmap(getRoundedBitmap(book));


public Bitmap getRoundedBitmap(Bitmap bitmap){
    Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    BitmapShader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
    Paint paint = new Paint();
    paint.setShader(shader);
    paint.setAntiAlias(true);
    Canvas c = new Canvas(circleBitmap);
    c.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2, bitmap.getWidth() / 2, paint);
    return circleBitmap;
}
