本文实例为大家分享了android自定义加减按钮的具体代码，供大家参考，具体内容如下
1、定义两个shape：
my_button_shape_normal.xml：
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
my_button_shape_pressed.xml：
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
2、定义一个drawable:my_button_style.xml
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
3、定义button布局(mybutton.xml):
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
4、定义MyButton类：
public class MyButton extends RelativeLayout {
private View view;
private Button add, reduce;
private OnAddReduceChangeStatusListener mAddReduceChangeStatusListener;
public MyButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
public MyButton(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
view = LayoutInflater.from(context).inflate(R.layout.mybutton, this, true);
init();
}
public MyButton(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
private void init() {
add = (Button) view.findViewById(R.id.add);
reduce = (Button) view.findViewById(R.id.reduce);
add.setOnTouchListener(new ComponentOnTouch());
reduce.setOnTouchListener(new ComponentOnTouch());
}
class ComponentOnTouch implements OnTouchListener {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.add:
if (mAddReduceChangeStatusListener != null) {
mAddReduceChangeStatusListener.add(MyButton.this.getId(),event.getAction());
}
break;
case R.id.reduce:
if (mAddReduceChangeStatusListener != null) {
mAddReduceChangeStatusListener.reduce(MyButton.this.getId(),event.getAction());
}
break;
}
return true;
}
}
public void setOnAddReduceChangeStatusListener(OnAddReduceChangeStatusListener listener) {
this.mAddReduceChangeStatusListener = listener;
}
public abstract interface OnAddReduceChangeStatusListener {
public abstract boolean add(int viewId,int eventAction);
public abstract boolean reduce(int viewId,int eventAction);
}
}
5、布局中使用：
6.代码中使用:
a.初始化：
mybutton = (MyButton) findViewById(R.id.mybutton_id); mybutton.setOnAddReduceChangeStatusListener(new OnAddReduceListener());
b.listener监听:
class OnAddReduceListener implements OnAddReduceChangeStatusListener {
@Override
public boolean add(int viewId, int eventAction) {
// TODO Auto-generated method stub
if (eventAction == MotionEvent.ACTION_DOWN) {
onTouchChange("add");
} else if (eventAction == MotionEvent.ACTION_UP) {
if (plusThread != null) {
isOnLongClick= false;
}
} else if (eventAction == MotionEvent.ACTION_MOVE) {
if (plusThread != null) {
isOnLongClick= true;
}
} else if (eventAction == MotionEvent.ACTION_CANCEL) {
if (plusThread != null) {
isOnLongClick= false;
}
}
return true;
}
@Override
public boolean reduce(int viewId, int eventAction) {
// TODO Auto-generated method stub
if (eventAction == MotionEvent.ACTION_DOWN) {
onTouchChange("reduce");
} else if (eventAction == MotionEvent.ACTION_UP) {
if (miusThread != null) {
isOnLongClick= false;
}
} else if (eventAction == MotionEvent.ACTION_MOVE) {
if (miusThread != null) {
isOnLongClick= true;
}
} else if (eventAction == MotionEvent.ACTION_CANCEL) {
if (miusThread != null) {
isOnLongClick= false;
}
}
return true;
}
}
private void onTouchChange(String method) {
if (method.equals("add")) {
plusThread = new PlusThread();
isOnLongClick= true;
plusThread.start();
} else if (method.equals("reduce")) {
miusThread = new MiusThread();
isOnLongClick= true;
miusThread.start();
}
}
c,定义两个线程用来加减：
// 减操作
class MiusThread extends Thread {
@Override
public void run() {
while (isOnLongClick) {
try {
Thread.sleep(200);
myHandler.sendEmptyMessage(1);
} catch (InterruptedException e) {
e.printStackTrace();
}
super.run();
}
}
}
// 加操作
class PlusThread extends Thread {
@Override
public void run() {
while (isOnLongClick) {
try {
Thread.sleep(200);
myHandler.sendEmptyMessage(2);
} catch (InterruptedException e) {
e.printStackTrace();
}
super.run();
}
}
}
使用Handler进行处理：
Handler myHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
if (msg.what == 1) {
//加操作
} else if (msg.what == 2) {
//减操作
}
}
};
