我正在设置一个页面圈布局轮菜单栏。我有一些图标。当图标(图像)变为圆形时,该图标应该变为可点击。如果图标圈出并且图标以圆圈形式出现,我该怎么办?如何点击这个粉红色图像只能在圆圈
我希望粉红色的图片会是背景,图标会出现圆圈,只能点击圈子
我使用了gama_wheel_v1.0.jar 所以你知道任何图书馆的例子可以帮助我

所选图标将来到此圈子:
这是我的主要活动:
import com.digitalaria.gama.wheel.Wheel;
import android.app.Activity;
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.Button;
public class SampleWheelActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init();
}
private Wheel wheel;
private Resources res;
private int[] icons = {
R.drawable.icon00, R.drawable.icon01, R.drawable.icon02,
R.drawable.icon03, R.drawable.icon04, R.drawable.icon05,
R.drawable.icon06, R.drawable.icon07, R.drawable.icon08,
R.drawable.icon09, R.drawable.icon10, R.drawable.icon11 };
private void init() {
res = getApplicationContext().getResources();
wheel = (Wheel) findViewById(R.id.wheel);
wheel.setItems(getDrawableFromData(icons));
wheel.setWheelDiameter(400);
}
private Drawable[] getDrawableFromData(int[] data) {
Drawable[] ret = new Drawable[data.length];
for (int i = 0; i < data.length; i++) {
ret[i] = res.getDrawable(data[i]);
}
return ret;
}
}
这是我的xml页面:
