Implementing code for dynamically adding a panel frame to Android _android

Here is the framework, said the point, in fact, not so complex, but an easy to expand the base class just. But at least it's a frame class code.

Copy Code code as follows:

Package Arui;

Import android.app.Activity;
Import Android.os.Handler;
Import Android.os.Looper;
Import Android.os.Message;
Import android.view.Gravity;
Import Android.view.LayoutInflater;
Import Android.view.View;
Import Android.view.ViewGroup.LayoutParams;
Import Android.view.ViewManager;
Import Android.widget.FrameLayout;

/**
* Base class for panel.
*
*/
Public abstract class Basepanel {

/**
* Left up position
*/
public static final int left_up = 1;

/**
* Right up position
*/
public static final int right_up = 2;

/**
* Left bottom position
*/
public static final int left_bottom = 3;

/**
* Right Bottom position
*/
public static final int right_bottom = 4;

private static final int default_margin = 10;

private static final int show_panel = 0;

activity of private activity;

private Layoutparams parameters;

Private view view = NULL;

private int layoutid;

/**
* constructor.
*
* @param activity
* This panel would be attached to the activity
* @param LayoutID
* The panel ' s layout ID
*/
Public Basepanel (activity activity, int layoutid) {
This.activity = activity;
This.layoutid = LayoutID;
}

/**
* The developer can use the "to" add the panel to the activity.
*
* @param Act
* Activity
* @param params
* Layoutparams
*/
public void Attach (Layoutparams params) {
Parameters = params;
Mhandler.sendmessage (Mhandler.obtainmessage (Show_panel));

}

/**
* The developer can use the "to" add the panel to the activity.
*
* @param Act
* Activity
* @param position
* Int. can use BASEPANEL.LEFT_UP,BASEPANEL.RIGHT_UP,
* Basepanel.right_bottom or Basepanel.left_bottom.
*/
public void attach (int position) {
Attach (position, Default_margin, Default_margin, Default_margin,
Default_margin);
}

/**

*
* @param Act
* Activity
* @param position
* Int. can use BASEPANEL.LEFT_UP,BASEPANEL.RIGHT_UP,
* Basepanel.right_bottom or Basepanel.left_bottom.
* @param leftMargin
* int, left margin.
* @param topMargin

* @param rightMargin

*/

params = new Framelayout.layoutparams (layoutparams.wrap_content,
Layoutparams.wrap_content);

Case RIGHT_UP:

Break
Case Left_bottom:
params.gravity = Gravity.left | Gravity.bottom;
Break
Case Right_bottom:

Break
Default
Break
}
Attach (params);
}

/**
* The developer can use this method to remove the panel from the activity.
*
*/
public void Remove () {
if (view!= null) {
Viewmanager Mviewmanager = (Viewmanager) view.getparent ();
if (Mviewmanager!= null) {

}
}
}
