是的,Android BadgeView 可以自定义形状。要实现自定义形状的 BadgeView,你可以使用自定义绘制的方法。以下是一个简单的示例,展示了如何创建一个自定义形状的 BadgeView:
build.gradle
文件中添加 BadgeView 依赖:dependencies {
implementation 'de.hdodenhof:circleimageview:3.1.0'
}
BadgeView
,并重写 onDraw()
方法:import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import androidx.annotation.NonNull;
import de.hdodenhof.circleimageview.CircleImageView;
public class CustomBadgeView extends CircleImageView {
private Paint badgePaint;
private RectF badgeRect;
public CustomBadgeView(@NonNull Context context) {
super(context);
init();
}
private void init() {
badgePaint = new Paint();
badgePaint.setAntiAlias(true);
badgePaint.setTextAlign(Paint.Align.CENTER);
badgePaint.setTextSize(12);
badgeRect = new RectF();
}
public void setBadgeShape(int color, float radius, float strokeWidth, float cornerRadius) {
badgePaint.setColor(color);
badgePaint.setStrokeWidth(strokeWidth);
badgeRect.set(0, 0, 2 * radius, 2 * radius);
badgeRect.offset(radius - cornerRadius, radius - cornerRadius);
}
@Override
protected void onDraw(@NonNull Canvas canvas) {
super.onDraw(canvas);
// Draw the circle image
canvas.drawCircle(getWidth() / 2f, getHeight() / 2f, getWidth() / 2f, badgePaint);
// Draw the badge
canvas.drawRoundRect(badgeRect, cornerRadius, cornerRadius, badgePaint);
}
}
CustomBadgeView
:<your.package.name.CustomBadgeView
android:id="@+id/custom_badge_view"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@drawable/ic_your_badge_icon" />
CustomBadgeView customBadgeView = findViewById(R.id.custom_badge_view);
customBadgeView.setBadgeShape(Color.RED, 40, 6, 10);
这样,你就可以创建一个自定义形状的 BadgeView 了。你可以根据需要调整 setBadgeShape()
方法中的参数,以实现不同的形状和样式。
