本文根据组件开发思想，首先介绍android自定义控件，然后将自定义的控件封装为jar包。最为实现滑动接听电话控件组。
一、目录结构
二、运行效果
三、代码实现
首先，自定义一个类incomingphone继承relativelayout
我要评论
public incomingphone(context context, attributeset attrs) {
super(context, attrs);
mcontext = context;
textview textview = new textview(mcontext);
textview.settext("caonima");
pickupview = new pickupview(mcontext);
hangupview = new hangupview(mcontext);
pickupview.setbackground(getresources().getdrawable(r.drawable.pick_up_background));
hangupview.setbackground(getresources().getdrawable(r.drawable.hang_up_background));
relativelayout.layoutparams lp1 = new relativelayout.layoutparams(viewgroup.layoutparams.wrap_content, viewgroup.layoutparams.wrap_content);
lp1.addrule(relativelayout.align_parent_right, relativelayout.true);
/ pickupview.setbackground(mcontext.getdrawable(r.drawable.pick_up_background));
pickupview.setpickuplistener(new pickupview.pickuplistener() {
@override
public void pickupevent() {
mincomingphoneresultlistener.incomingphoneresultevent("pickup");
}
});
hangupview.sethanguplistener(new hangupview.hanguplistener() {
@override
public void hangupevent() {
mincomingphoneresultlistener.incomingphoneresultevent("hangup");
}
});
pickupview.setontouchlistener(new ontouchlistener() {
@override
public boolean ontouch(view v, motionevent event) {
switch (event.getaction()) {
case motionevent.action_down:
hangupview.setvisibility(view.gone);
break;
case motionevent.action_up:
hangupview.setvisibility(view.visible);
pickupview.setvisibility(view.visible);
break;
default:
break;
}
return false;
}
});
hangupview.setontouchlistener(new ontouchlistener() {
@override
public boolean ontouch(view v, motionevent event) {
switch (event.getaction()) {
case motionevent.action_down:
pickupview.setvisibility(view.gone);
break;
case motionevent.action_up:
hangupview.setvisibility(view.visible);
pickupview.setvisibility(view.visible);
break;
default:
break;
}
return false;
}
});
addview(textview);
addview(pickupview);
addview(hangupview,lp1);
}
构造函数中添加子控件，并添加滑动事件以及监听器，其中pickupview、hangupview是自定义的子控件，是该类的内部类两个几乎一样，我贴出其中一个
class pickupview extends relativelayout {
private context mcontext;
private final int minwidth = 360;
private int screenwidth;
private int mwidth;
private int mheight;
private pickuplistener mpickuplistener;
public void setpickuplistener(pickuplistener mpickuplistener) {
this.mpickuplistener = mpickuplistener;
}
public int getmwidth() {
mwidth = getlayoutparams().width;
return mwidth;
}
public void setmwidth(int width) {
mwidth = width;
getlayoutparams().width = mwidth;
requestlayout();
}
public int getmheight() {
mheight = getlayoutparams().height;
return mheight;
}
public void setmheight(int height) {
mheight = height;
getlayoutparams().height = mheight;
requestlayout();
}
public pickupview(context context) {
super(context);
windowmanager wm = (windowmanager) getcontext()
.getsystemservice(context.window_service);
screenwidth = wm.getdefaultdisplay().getwidth();
}
@override
public boolean ontouchevent(motionevent event) {
int firstx = 0;
int lastx = 0;
mwidth = getmwidth();
switch (event.getaction()) {
case motionevent.action_down:
firstx = (int) event.getx();
// objectanimator.ofint(this,"mwidth",500).setduration(5000).start();
break;
case motionevent.action_move:
lastx = (int) event.getx();
setmwidth(lastx);
// log.e("起始坐标", string.valueof(firstx));
// log.e("结束坐标", string.valueof(lastx));
break;
case motionevent.action_up:
lastx = (int) event.getrawx();
if (lastx > screenwidth / 7 * 6) {
mpickuplistener.pickupevent();
} else {
setmwidth(minwidth);
}
break;
default:
break;
}
return true;
}
public interface pickuplistener {
public void pickupevent();
}
}
在xml文件中定义
<relativelayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.example.administrator.pickuptest.incomingphone
android:id="@+id/incoming"
android:layout_width="match_parent"
android:layout_height="80dp">
</com.example.administrator.pickuptest.incomingphone>
<button
android:id="@+id/btn_hang_up"
android:layout_margin="10dp"
android:background="#ff0000"
android:textcolor="#ffffff"
android:visibility="gone"
android:layout_width="match_parent"
android:layout_height="80dp"
android:text="挂断"/>
</relativelayout>
在activity中使用
incomingphone = (incomingphone)findviewbyid(r.id.incoming);
mbtnhangup=(button)findviewbyid(r.id.btn_hang_up);
incomingphone.setincomingphoneresultlistener(new incomingphone.incomingphoneresultlistener() {
@override
public void incomingphoneresultevent(string result) {
if ("pickup".equals(result)){
log.e("", "打电话");
incomingphone.setvisibility(view.gone);
mbtnhangup.setvisibility(view.visible);
}
else {
log.e("","挂电话");
incomingphone.setvisibility(view.gone);
mbtnhangup.setvisibility(view.visible);
}
}
});
问题：图片大小以及屏幕适配可能会有些问题，如果使用，请注意测试。以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持移动技术网。
