android自定义加减按钮

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：

my_button_shape_pressed.xml：

2、定义一个drawable:my_button_style.xml

3、定义button布局(mybutton.xml):

4、定义MyButton类：

publicclassMyButtonextendsRelativeLayout{
privateViewview;
privateButtonadd,reduce;

privateOnAddReduceChangeStatusListenermAddReduceChangeStatusListener;

publicMyButton(Contextcontext,AttributeSetattrs,intdefStyle){
super(context,attrs,defStyle);
//TODOAuto-generatedconstructorstub
}

publicMyButton(Contextcontext,AttributeSetattrs){
super(context,attrs);
//TODOAuto-generatedconstructorstub
view=LayoutInflater.from(context).inflate(R.layout.mybutton,this,true);

init();
}

publicMyButton(Contextcontext){
super(context);
//TODOAuto-generatedconstructorstub
}

privatevoidinit(){
add=(Button)view.findViewById(R.id.add);
reduce=(Button)view.findViewById(R.id.reduce);

add.setOnTouchListener(newComponentOnTouch());
reduce.setOnTouchListener(newComponentOnTouch());
}

classComponentOnTouchimplementsOnTouchListener{

@Override
publicbooleanonTouch(Viewv,MotionEventevent){
//TODOAuto-generatedmethodstub
switch(v.getId()){
caseR.id.add:
if(mAddReduceChangeStatusListener!=null){
mAddReduceChangeStatusListener.add(MyButton.this.getId(),event.getAction());
}
break;
caseR.id.reduce:
if(mAddReduceChangeStatusListener!=null){
mAddReduceChangeStatusListener.reduce(MyButton.this.getId(),event.getAction());
}
break;
}
returntrue;
}
}

publicvoidsetOnAddReduceChangeStatusListener(OnAddReduceChangeStatusListenerlistener){
this.mAddReduceChangeStatusListener=listener;
}

publicabstractinterfaceOnAddReduceChangeStatusListener{
publicabstractbooleanadd(intviewId,inteventAction);

publicabstractbooleanreduce(intviewId,inteventAction);

}
}

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(newOnAddReduceListener());

b.listener监听:

classOnAddReduceListenerimplementsOnAddReduceChangeStatusListener{

@Override
publicbooleanadd(intviewId,inteventAction){
//TODOAuto-generatedmethodstub
if(eventAction==MotionEvent.ACTION_DOWN){
onTouchChange("add");
}elseif(eventAction==MotionEvent.ACTION_UP){
if(plusThread!=null){
isOnLongClick=false;
}
}elseif(eventAction==MotionEvent.ACTION_MOVE){
if(plusThread!=null){
isOnLongClick=true;
}
}elseif(eventAction==MotionEvent.ACTION_CANCEL){
if(plusThread!=null){
isOnLongClick=false;
}
}
returntrue;
}

@Override
publicbooleanreduce(intviewId,inteventAction){
//TODOAuto-generatedmethodstub
if(eventAction==MotionEvent.ACTION_DOWN){
onTouchChange("reduce");
}elseif(eventAction==MotionEvent.ACTION_UP){
if(miusThread!=null){
isOnLongClick=false;
}
}elseif(eventAction==MotionEvent.ACTION_MOVE){
if(miusThread!=null){
isOnLongClick=true;
}
}elseif(eventAction==MotionEvent.ACTION_CANCEL){
if(miusThread!=null){
isOnLongClick=false;
}
}
returntrue;
}
}

privatevoidonTouchChange(Stringmethod){
if(method.equals("add")){
plusThread=newPlusThread();
isOnLongClick=true;
plusThread.start();
}elseif(method.equals("reduce")){
miusThread=newMiusThread();
isOnLongClick=true;
miusThread.start();
}
}

c,定义两个线程用来加减：

//减操作
classMiusThreadextendsThread{
@Override
publicvoidrun(){
while(isOnLongClick){
try{
Thread.sleep(200);
myHandler.sendEmptyMessage(1);
}catch(InterruptedExceptione){
e.printStackTrace();
}
super.run();
}
}
}

//加操作
classPlusThreadextendsThread{
@Override
publicvoidrun(){
while(isOnLongClick){
try{
Thread.sleep(200);
myHandler.sendEmptyMessage(2);
}catch(InterruptedExceptione){
e.printStackTrace();
}
super.run();
}
}
}

使用Handler进行处理：

HandlermyHandler=newHandler(){

@Override
publicvoidhandleMessage(Messagemsg){
//TODOAuto-generatedmethodstub
if(msg.what==1){
//加操作
}elseif(msg.what==2){
//减操作
}
}
};
