Android custom Sliding answering phone control group instance _android

Based on the idea of component development, this article first introduces the Android custom control and then encapsulates the custom control as a jar package. The most implementation of the sliding answering phone control group.

First, directory structure

Second, the Operation effect

Third, code implementation

First, customize a class Incomingphone inheritance Relativelayout

Public Incomingphone (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 () {mincoming 
      Phoneresultlistener.incomingphoneresultevent ("Hangup"); 
    } 
    }); Pickupview.setontouchlistener (New Ontouchlistener () {@Override public boolean ontouch (View V, motionevent E Vent) {switch (event.getaction ()) {case MotionEvent.ACTION_DOWN:hangUpView.setVisibili 
            Ty (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 E Vent) {switch (event.getaction ()) {case MotionEvent.ACTION_DOWN:pickUpView.setVisibili Ty (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); 
 }

The

Constructor adds a child control and adds a sliding event as well as a listener, where Pickupview, Hangupview is a custom child control, is the inner class of the class two almost the same, I posted one of the

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 {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"). Setduration (5000). Start (); 
      Break 
        Case MotionEvent.ACTION_MOVE:lastX = (int) event.getx (); 
Setmwidth (LASTX); 
LOG.E ("Starting coordinates", string.valueof (FIRSTX)); 
        LOG.E ("End coordinates", 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 (); 
 } 
}

Define in XML file

<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 = "Hang Up"/> 
  </RelativeLayout> 

Use in activity

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 ("", "call"); 
      Incomingphone.setvisibility (view.gone); 
      Mbtnhangup.setvisibility (view.visible); 
    } 
    else { 
      log.e ("", "hang Phone"); 
      Incomingphone.setvisibility (view.gone); 
      Mbtnhangup.setvisibility (view.visible); 
    } 
  } 
); 

Problem: Picture size and screen adaptation may have some problems, if used, please note the test. The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
