Android动态实现shape,android – 动态创建一个Shape

例：

import android.graphics.drawable.GradientDrawable;

public class SomeDrawable extends GradientDrawable {

public SomeDrawable(int pStartColor, int pCenterColor, int pEndColor, int pStrokeWidth, int pStrokeColor, float cornerRadius) {

super(Orientation.BOTTOM_TOP,new int[]{pStartColor,pCenterColor,pEndColor});

setStroke(pStrokeWidth,pStrokeColor);

setShape(GradientDrawable.RECTANGLE);

setCornerRadius(cornerRadius);

}

}

用法：

public class MyActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

SomeDrawable vDrawable = new SomeDrawable(Color.BLACK,Color.GREEN,Color.LTGRAY,2,Color.RED,50);

View vView = new View(this);

vView.setBackgroundDrawable(vDrawable);

setContentView(vView);

}

}

结果：
