PopupWindow的应用 1

PopupWindow的使用，这里是分析QQ通讯录的源码看到的，这里分享下：
 
  以“拨号盘”界面的-最近联系人 右边的“筛选”按钮为例：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:id="@+id/tabcontent"
	android:layout_width="fill_parent" android:layout_height="fill_parent"
	xmlns:android="http://schemas.android.com/apk/res/android">
		<RelativeLayout android:id="@+id/tv_call_log" android:background="@drawable/bg_header" android:layout_width="fill_parent" android:layout_height="wrap_content">
			<TextView android:textSize="20.0sp" android:textColor="#ffffff" android:gravity="center" android:id="@+id/titleText"
				android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="最近联系人" android:layout_centerInParent="true" />
			<com.farmer.views.PopuMenuTextButton
				android:textColor="#ffffff" android:gravity="center" android:id="@+id/titleImg" android:background="@drawable/bg_top_btn" android:layout_width="46.0dip"
				android:layout_height="34.0dip" android:layout_marginRight="4.0dip" android:text="筛选" android:layout_alignParentRight="true" android:layout_centerVertical="true" />
		</RelativeLayout>
</LinearLayout>

上面的PopuMenuTextButton 就是需要复写的Butoon

public abstract interface nl
{
  public abstract void popAwindow(View paramView);
}

public class PopuMenuTextButton extends Button
{
  private nl pwindow;

  public PopuMenuTextButton(Context paramContext, AttributeSet paramAttributeSet)
  {
    super(paramContext, paramAttributeSet);
  }

  protected void onDetachedFromWindow()
  {
    if (this.pwindow != null)
      this.pwindow.popAwindow(this);
    super.onDetachedFromWindow();
  }

  public void setOnDetachedListener(nl paramnl)
  {
    this.pwindow = paramnl;
  }
}

下面就是Activty的关键代码：

private PopuMenuTextButton pbtn;
	private PopupWindow pwindow;
         //onCreate.......
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.layout_dialerpad);
		this.pbtn = (PopuMenuTextButton) findViewById(R.id.titleImg);
		pbtn.setOnClickListener(this);}
       //显示PopupWindow 窗口
       public void showPop(){
		int i1 = -1;
	    if (upOrdown() == i1){
                  //这边是需要再构造一个布局文件的
	    	View localView1 = LayoutInflater.from(this).inflate(
	    		R.layout.layout_popup_calllog_type, null);
	    	View localView2 = localView1.findViewById(R.id.popup_callLog_all);
	    	View localView3 = localView1.findViewById(R.id.popup_callLog_miss);
	    	View localView4 = localView1.findViewById(R.id.popup_callLog_incoming);
	    	View localView5 = localView1.findViewById(R.id.popup_callLog_outgoing);
	    	localView2.setOnClickListener(this);
	    	localView3.setOnClickListener(this);
	    	localView4.setOnClickListener(this);
	    	localView5.setOnClickListener(this);
	    	PopupWindow localPopupWindow1 = new PopupWindow(localView1, i1, i1);
	    	this.pwindow = localPopupWindow1;
	    	this.pwindow.showAsDropDown(this.pbtn);
	    }
	}

public int upOrdown() {
		int i1 = -1;
		if ((this.pwindow != null) && (this.pwindow.isShowing())) {
			this.pwindow.dismiss();
			i1 = 1;
		}
		return i1;
	}

@Override
	public void popAwindow(View paramView) {
		upOrdown();
	}

PopupWindow的布局文件layout_popup_calllog_type 如下 如下 如下.....
怎么也写不下了 我悲剧 只能写到下个文章中去了。
