3種類のポップアップウィンドウdialog,popupWindow,ContextMenu

収集した.私はただこの3種類のポップアップのウィンドウの方式だけを知っていて、新しい方法があって、面倒なヒントを与えて、ありがとうございます
1、PopupWindow
 

package com.zeng.alertdialog;

import android.app.Activity;
import android.os.Bundle;
import android.util.EventLog.Event;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.PopupWindow;

public class PopupWindowsActivity extends Activity {
	PopupWindow m_popupWindow;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.popup_main);
		final Button btn_menu = (Button) findViewById(R.id.but_menu);
		btn_menu.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				if (m_popupWindow == null) {

					LayoutInflater layoutInflater = getLayoutInflater();
					View view = layoutInflater.inflate(R.layout.popup_menu,
							null);
					// PopupWindow view, ： 
					m_popupWindow = new PopupWindow(view, 100, 100);
					// PopupWindow  ， view 
					// ， view x y 
					m_popupWindow.showAsDropDown(btn_menu, 0, 0);

				} else {
					if (m_popupWindow.isShowing()) {
						m_popupWindow.dismiss();
					}else {
						m_popupWindow.showAsDropDown(btn_menu, 0, 0);
					}
				}
			}
		});
	}

	public boolean onTouchEvent(MotionEvent event) {
		if (event.getAction() == MotionEvent.ACTION_DOWN) {
			Log.i("zeng", "MotionEvent.ACTION_DOWN");
			m_popupWindow.dismiss();
			return true;
		}

		//  m_popupWindow 
		// return super.onTouchEvent(event);
		return true;
	}

}

2、ContextMenu

package com.zeng.alertdialog;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.ContextMenu;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ContextMenu.ContextMenuInfo;
import android.widget.Toast;

public class ContextMenuDemo extends Activity {
	final int C_MENU_NEW = Menu.FIRST;
	final int C_MENU_OPEN = Menu.FIRST + 1;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		LayoutInflater infalter = (LayoutInflater) this
				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		View view = infalter.inflate(R.layout.contextmenu, null);
		registerForContextMenu(view);//  View  ， 
		setContentView(view);
	}

	@Override
	public void onCreateContextMenu(ContextMenu menu, View v,
			ContextMenuInfo menuInfo) {
		// TODO Auto-generated method stub
		super.onCreateContextMenu(menu, v, menuInfo);
		menu.add(0, C_MENU_NEW, 0, " ");
		menu.add(0, C_MENU_OPEN, 0, " ");
		Log.i("zeng", "onCreateContextMenu");

	}

	@Override
	public boolean onContextItemSelected(MenuItem item) {

		Log.i("zeng", "onContextItemSelected");
		switch (item.getItemId()) {
		case C_MENU_NEW:
			Toast.makeText(this, " ", Toast.LENGTH_LONG).show();
			break;
		case C_MENU_OPEN:
			Toast.makeText(this, " ", Toast.LENGTH_LONG).show();
			break;
		}
		return super.onContextItemSelected(item);
	}
}
