imageview 中的圆形图像，来自它的 ID

Question

我需要将我从数据库中获取的图像制作成圆形

我已经制作了这段代码，但我不知道如何完成它以使图像成为圆形

请帮忙

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details);
    name = (TextView) findViewById(R.id.names);
    date = (TextView) findViewById(R.id.dates);
    Story = (TextView) findViewById(R.id.story);
    im = (ImageView) findViewById(R.id.img_car);
    im.setScaleType(ImageView.ScaleType.FIT_XY);

    //ScrollView scroller = new ScrollView(this);
    //scroller.addView(Story);
    Bundle extras = getIntent().getExtras();

    int idf = extras.getInt("index");
    Book selectedBook;
    db = new SQLhelper(getApplicationContext());

    // read the book with "id" from the database
    selectedBook = db.readBook(++idf);
    name.setText(selectedBook.getTitle());
    date.setText(selectedBook.getdate());
    Story.setText(selectedBook.getstory()+"\n \n ");

    pname = selectedBook.getTitle();
    test = selectedBook.getimage();   
    int id = getResources().getIdentifier("com.example.tarekhy:drawable/" + test, null, null);  
    im.setImageResource(id);

}

这是 xml

我觉得我需要做一个样式

我尝试这样做，但失败了

请帮忙

你需要来自CircularImageView的CircularImageView

在 xml 文件中，您必须替换此代码而不是 Imageview :-<de.hdodenhof.circleimageview.CircleImageView android:id ="@+id/img_car" android:layout_width="160dp" android:layout_height="160dp" android:layout_centerInParent="true" app:border_width="2dp" app:border_color="@color/dark" />

在活动文件中替换此代码而不是 Imageview：-

CircleImageView im= (CircleImageView) findViewById(R.id.img_car);
