我正在尝试使用圆角(以及选择的背景颜色)创建一个可以重复使用不同背景颜色的视图; 很难解释,所以这是我的代码:
/app/src/com/packagename/whatever/CustomDrawableView.java
package com.packagename.whatever;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.drawable.PaintDrawable;
import android.util.AttributeSet;
import android.view.View;
public class CustomDrawableView extends View {
private PaintDrawable mDrawable;
int radius;
private void init(AttributeSet attrs) {
TypedArray a = getContext().obtainStyledAttributes(attrs,R.styleable.RoundedRect);
radius = a.getInteger(R.styleable.RoundedRect_radius, 0);
}
public CustomDrawableView(Context context, AttributeSet attrs) {
super(context, attrs);
init(attrs);
mDrawable = new PaintDrawable();
}
protected void onDraw(Canvas canvas) {
mDrawable.setCornerRadius(radius);
mDrawable.draw(canvas);
}
}
