Android自定义滑动接听电话控件组实例

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

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。
