自定义PopupWindow1

什么都不多说，看图先：



点击文本框，弹出最下面的PopupWindow。
很简单的啦，不解释。源码：

package com.dl.view;import android.content.Context;import android.graphics.drawable.BitmapDrawable;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.LinearLayout.LayoutParams;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.CheckBox;import android.widget.CompoundButton;import android.widget.GridView;import android.widget.PopupWindow;import android.widget.TextView;import com.dl.app.R;public class NumbersPickerPopupWindow extends PopupWindow{private Context context;private String[] balls=new String[]{"0","1","2","3","4","5","6","7","8","9"};private final String split=" "; private Button btn_ok;private String selectedNumbers;private String[] selectedNumbersArray;private GridViewAdapter adapter;public NumbersPickerPopupWindow(Context context,View view,String title,String selectedNumbers){super(view, LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT, true);this.context=context;this.selectedNumbers=selectedNumbers;selectedNumbersArray=selectedNumbers.trim().split(split);this.setBackgroundDrawable(new BitmapDrawable());//必须设置background才能消失  this.setOutsideTouchable(false);              //自定义动画        this.setAnimationStyle(R.style.PopupAnimation);      //使用系统动画  //      mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);        this.update();        this.setTouchable(true);      this.setFocusable(false);            GridView gridView=(GridView)view.findViewById(R.id.gridView);            adapter=new GridViewAdapter(context,balls);            gridView.setAdapter(adapter);            TextView tv_tips=(TextView)view.findViewById(R.id.tv_tips);      tv_tips.setText(title);            btn_ok=(Button)view.findViewById(R.id.btn_ok);      btn_ok.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {// TODO Auto-generated method stubif(onOkClickListener!=null){onOkClickListener.onOkClick(v);}if(isShowing())dismiss();}});      }public void setSelectedNumbers(String selectedNumbers){this.selectedNumbers=selectedNumbers;selectedNumbersArray=selectedNumbers.trim().split(split);adapter.notifyDataSetChanged();}class GridViewAdapter extends BaseAdapter{private Context context;private String[] balls;    public GridViewAdapter(Context context,String[] balls){    this.context=context;    this.balls=balls;//    num=numbers.trim().split(split);        }    public int getCount() {// TODO Auto-generated method stubreturn balls.length;}public Object getItem(int position) {// TODO Auto-generated method stubreturn balls[position];}public long getItemId(int position) {// TODO Auto-generated method stubreturn position;}public View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubif(convertView==null){convertView=LayoutInflater.from(context).inflate(R.layout.simple_grid_item_1_red, null);}CheckBox checkBox = (CheckBox)convertView.findViewById(R.id.checkBox);//checkBox.setText(balls[position]);if(selectedNumbersArray!=null&&selectedNumbersArray.length>0){for(int i=0;i<selectedNumbersArray.length;i++){if(selectedNumbersArray[i].equals(String.valueOf(position))){checkBox.setChecked(true);}}}checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {// TODO Auto-generated method stubif(onItemCheckedListener!=null){onItemCheckedListener.onItemCheckedChanged(buttonView,isChecked);}}});return convertView;}}//接口private OnItemCheckedListener onItemCheckedListener;public void setOnItemCheckedListener(OnItemCheckedListener onItemCheckedListener) {this.onItemCheckedListener = onItemCheckedListener;}public interface OnItemCheckedListener{public void onItemCheckedChanged(CompoundButton buttonView, boolean isChecked);}private OnOkClickListener onOkClickListener;public void setOnOkClickListener(OnOkClickListener onOkClickListener) {this.onOkClickListener = onOkClickListener;}public interface OnOkClickListener{public void onOkClick(View v);}}

用法：

LayoutInflater mLayoutInflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);          view = mLayoutInflater.inflate(R.layout.popwindow, null);          NumbersPickerPopupWindow p=new NumbersPickerPopupWindow(context,view,"选择需要的数字","0 3 6");p.setSelectedNumbers("1 4 6");//动态改变选中的值,之间用空格隔开p.showAtLocation(views[0], Gravity.BOTTOM, 0, 0);//还可以定义接口......

布局文件popwindow.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="vertical"     android:background="@color/bg_blue_2"    >   <RelativeLayout         android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:background="@drawable/bg_title_bar"    android:padding="5dip"       >       <TextView         android:id="@+id/tv_tips"        android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="每位至少选择一个数字"    android:textColor="@color/white"    android:layout_centerInParent="true"        />        <Button         android:id="@+id/btn_ok"        android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="确定"    android:textColor="@color/white"    android:background="@drawable/bg_btn_intro"    android:layout_alignParentTop="true"    android:layout_alignParentRight="true"        />   </RelativeLayout>     <View       android:layout_width="fill_parent"    android:layout_height="1dip"    android:background="?android:attr/listDivider"      />  <GridView       android:id="@+id/gridView"      android:layout_width="wrap_content"    android:layout_height="fill_parent"    android:numColumns="5"    android:horizontalSpacing="12dip"    android:verticalSpacing="10dip"    android:paddingTop="10dip"    android:paddingBottom="10dip"    android:paddingLeft="40dip"    android:paddingRight="40dip"    android:gravity="center"    android:layout_gravity="center"      /></LinearLayout>

styles.xml中定义的动画：

<style name="PopupAnimation" parent="android:Animation"  mce_bogus="1" >        <item name="android:windowEnterAnimation">@anim/anim_in_bottom</item>        <item name="android:windowExitAnimation">@anim/anim_out_bottom</item>    </style>

2个动画：
anim_in_bottom.xml,anim_out_bottom.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="200" android:fillAfter="true"android:interpolator="@android:anim/bounce_interpolator"/></set><?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromYDelta="0" android:toYDelta="100%p" android:duration="200"android:fillAfter="true"android:interpolator="@android:anim/bounce_interpolator"/></set>

simple_grid_item_1_red.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"  android:layout_height="wrap_content"    android:gravity="center"    ><CheckBox    android:id="@+id/checkBox"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:textColor="@color/white"  android:gravity="center"  android:button="@null"      android:background="@drawable/bg_checkbox_redball"    android:checked="false"  />    </LinearLayout>

bg_checkbox_redball.xml：

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_checked="true" android:drawable="@drawable/red_focus" />     <item android:state_checked="false" android:drawable="@drawable/red" /> </selector>
