Java 如何在android中添加具有重叠透明背景的图像按钮？

这是我的设计，圆圈的三个部分是三个按钮。如何选择特定的按钮

到目前为止，我所做的是：

• 把这三部分剪下来
• 这三个部分分别设置为图像视图
• 将它们整合成如下所示的圆形（中心圆形部分是另一个按钮）

但是按钮后面的透明矩形区域重叠，我无法选择所需的按钮

我的代码如下：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.butto);
    gp = new GPSTracker(ButtonhomeActivity.this);
    final NotificationManager mgr=
            (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    Log.e("dbfhb","fcxcv");
    se = (ImageView) findViewById(R.id.imageView4);
    ca = (ImageView) findViewById(R.id.imageView3);
    gr = (ImageView) findViewById(R.id.imageView2);
    ab= (ImageView) findViewById(R.id.imageView1);
    // show location button click event
    se.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP){
                Log.e("inside se ontouch","..");
                // Do what you want
                Log.e("inside onclick","...");
                // check if GPS enabled
                db= openOrCreateDatabase("Mydb", MODE_PRIVATE, null);
                if(gp.isGPSEnabled&&x==0){
                    Log.e("onclick gpsss","gpss");
                    la = gp.getLatitude();
                    lo = gp.getLongitude();
                    Log.e("lat",String.valueOf(la));
                    Log.e("lon",String.valueOf(lo));
                    // \n is for new line
                    Toast.makeText(ButtonhomeActivity.this, "Your Location is - \nLat: " + la + "\nLong: " + lo, Toast.LENGTH_LONG).show();
