Android based widget component to implement object move/control Drag function Example _android

The example in this article tells you that Android implements object move/control drag based on widget components. Share to everyone for your reference, specific as follows:

Package Com.sky;
Import android.app.Activity;
Import Android.os.Bundle;
Import android.view.KeyEvent;
Import android.view.MotionEvent;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.widget.AbsoluteLayout;
Import Android.widget.Button;  @SuppressWarnings ("deprecation") public class Abosolutemove extends activity implements Onclicklistener {/** when The activity is the created.
 * * Public Button button1;
 Public Button button2;
 Public Button Button3;
 Public Button Button4;
 Button tmp;//temporarily save, select button int x;
 int y; The int flag;//is used to flag which button is selected @Override public void OnCreate (Bundle savedinstancestate) {super.oncreate (Savedinstan
    Cestate);
    Setcontentview (R.layout.main);
    button1= (Button) Findviewbyid (r.id.widget27);
    Button2= (Button) Findviewbyid (R.ID.WIDGET28);
    button3= (Button) Findviewbyid (r.id.widget29);
    button4= (Button) Findviewbyid (R.ID.WIDGET30);
    Button1.setonclicklistener (this); Button2.setonclickliStener (this);
    Button3.setonclicklistener (this);
  Button4.setonclicklistener (this); @Override public void OnClick (View v) {//TODO auto-generated Method Stub switch (V.getid ()) {case R.id.widget2
  7:flag=r.id.widget27;
  Settitle ("Button1");
  Break
  Case R.id.widget28:flag=r.id.widget28;
  Settitle ("Button2");
  Break
  Case r.id.widget29:flag=r.id.widget29;
  Settitle ("Button3");
  Break
  Case R.id.widget30:flag=r.id.widget30;
  Settitle ("Button4");
 Break @Override public boolean onKeyDown (int keycode, keyevent event) {//TODO auto-generated a stub return Supe
 R.onkeydown (KeyCode, event); @Override public boolean ontouchevent (Motionevent event) {//TODO auto-generated method Stub x = (int) Event.getx (
    );
    y = (int) event.gety (); tmp= (Button) Findviewbyid (flag);//Get selected Button absolutelayout.layoutparams params1=new absolutelayout.layoutparams
    (50,50,X-25,Y-50); Tmp.setlayoutparams (PARAMS1);/Set the new location of the button SWItch (Event.getaction ()) {case MotionEvent.ACTION_DOWN:tmp.invalidate ();
        Tmp.settext ("checked down");
      Break
       Case MotionEvent.ACTION_UP:tmp.invalidate ();
        Tmp.settext ("checked up");
      Break
       Case MotionEvent.ACTION_MOVE:tmp.invalidate ();
        Tmp.settext ("select Move");
    Break
 Return Super.ontouchevent (event);

 }
}
