Android 使用PopupWindow实现弹出更多的菜单实例详解

最近想要做一个弹出更多的菜单，而原生的弹出菜单却不是我们想要的效果，所以必然要自定义菜单咯。本人也是借鉴网上的资料进行封装的，感觉还蛮不错的。

原生的菜单如下图：

自定义之后的效果图：

是不是看到这里之后，对比可知，原生的效果不太理想，所以还是再自己定义吧！

1、PopupWindow可以说是一个浮动在Activity之上的容器，通常用来显示自定义的视图。弹出菜单的封装PopMenuMore

/**

 */
public class PopMenuMore {
 /**
 * 上下文.
 */
 private Context mContext;
 /**
 * 菜单项
 */
 private ArrayList<PopMenuMoreItem> mItemList;
 /**
 * 列表适配器.
 */
 private BaseAdapter mAdapter;
 /**
 * 菜单选择监听.
 */
 private OnItemSelectedListener mListener;
 /**
 * 下角图标
 */
 private ImageView cornerIcon;
 /**
 * 列表.
 */
 private ListView mListView;
 /**
 * 弹出窗口.
 */
 private PopupWindow mPopupWindow;
 public PopMenuMore(Context context) {
 mContext = context;
 mItemList = new ArrayList<>();
 View view = onCreateView(context);
 view.setFocusableInTouchMode(true);
 mAdapter = onCreateAdapter(context, mItemList);
 cornerIcon = findCornerView(view);
 mListView = findListView(view);
 mListView.setAdapter(mAdapter);
 mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
  PopMenuMoreItem item = (PopMenuMoreItem) mAdapter.getItem(position);
  if (mListener != null) {
   mListener.selected(view, item, position);
  }
  mPopupWindow.dismiss();
  }
 });
 view.setOnKeyListener(new View.OnKeyListener() {
  @Override
  public boolean onKey(View v, int keyCode, KeyEvent event) {
  if (keyCode == KeyEvent.KEYCODE_MENU && mPopupWindow.isShowing()) {
   mPopupWindow.dismiss();
   return true;
  }
  return false;
  }
 });
 mPopupWindow = new PopupWindow(view, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
 mPopupWindow.setBackgroundDrawable(new ColorDrawable(0x00000000));
 setBackgroundColor(Color.parseColor("#000000"));
 setCorner(R.mipmap.triangle);
 }
 /**
 * 设置ListView背景
 *
 * @param argb Color.parseColor("..")
 */
 public void setBackgroundColor(int argb) {
// int strokeWidth = 5; // 3dp 边框宽度
 int roundRadius = 5; // 8dp 圆角半径
// int strokeColor = Color.parseColor("#2E3135");//边框颜色
// int fillColor = Color.parseColor("#DFDFE0");//内部填充颜色
 GradientDrawable gd = new GradientDrawable();//创建drawable
 gd.setColor(argb);
 gd.setCornerRadius(roundRadius);
// gd.setStroke(strokeWidth, strokeColor);
 mListView.setBackgroundDrawable(gd);
 }
 /**
 * 设置下角图标
 *
 * @param resId
 */
 public void setCorner(int resId) {
 cornerIcon.setBackgroundResource(resId);
 }
 protected View onCreateView(Context context) {
 return LayoutInflater.from(context).inflate(R.layout.layout_popmenu_more, null);
 }
 protected ImageView findCornerView(View view) {
 return (ImageView) view.findViewById(R.id.corner_iv);
 }
 protected ListView findListView(View view) {
 return (ListView) view.findViewById(R.id.menu_listview);
 }
 /**
 * 菜单列表中的适配器.
 *
 * @param context
 * @param items 表示所有菜单项.
 * @return
 */
 protected BaseAdapter onCreateAdapter(Context context, ArrayList<PopMenuMoreItem> items) {
 return new PopMenuMoreAdapter(context, items);
 }
 /**
 * 添加菜单项
 *
 * @param item
 */
 public void addItem(PopMenuMoreItem item) {
 mItemList.add(item);
 mAdapter.notifyDataSetChanged();
 }
 public void addItems(List<PopMenuMoreItem> items) {
 if (items != null) {
  mItemList.clear();
 }
 for (PopMenuMoreItem item : items) {
  mItemList.add(item);
 }
 mAdapter.notifyDataSetChanged();
 } 

 /**

 *
 * @param parent 所指定的View
 */
 public void showAsDropDown(View parent) {
 mPopupWindow.showAsDropDown(parent);
 }
 /**

 */
 public void dismiss() {
 mPopupWindow.dismiss();
 }
 /**
 * 设置菜单选择监听.

 */
 public void setOnItemSelectedListener(OnItemSelectedListener listener) {
 mListener = listener;
 }
 /**

 public boolean isShowing() {
 return mPopupWindow.isShowing();
 }
 /**

 public interface OnItemSelectedListener {
 /**
  * 菜单被选择时的回调接口.
  *
  * @param view 被选择的内容的View.
  * @param item 被选择的菜单项.
  * @param position 被选择的位置.
  */
 void selected(View view, PopMenuMoreItem item, int position);
 }
} 

2、菜单中ListView的适配器：PopMenuMoreAdapter

/**
 * @author SoBan
 * @create 2017/4/12 10:29.
 */
public class PopMenuMoreAdapter extends BaseAdapter {
 private ArrayList<PopMenuMoreItem> items;
 private Context context;
 public PopMenuMoreAdapter(Context context, ArrayList<PopMenuMoreItem> items) {
 this.context = context;
 this.items = items;
 }
 @Override
 public int getCount() {
 return items.size();
 }
 @Override
 public PopMenuMoreItem getItem(int position) {
 return items.get(position);
 }
 @Override
 public long getItemId(int position) {
 return position;
 }
 @Override
 public View getView(int position, View view, ViewGroup parent) {
 if (view == null) {
  view = LayoutInflater.from(context).inflate(R.layout.item_popmenu_more, null);
  ViewHolder holder = new ViewHolder();
  holder.icon = (ImageView) view.findViewById(R.id.menu_icon);
  holder.text = (TextView) view.findViewById(R.id.menu_text);
  view.setTag(holder);
 } else if (view.getParent() != null) {
  ((ViewGroup) view.getParent()).removeView(view);
 }
 ViewHolder holder = (ViewHolder) view.getTag();
 PopMenuMoreItem item = items.get(position);
 if (item.getResId() == 0) {
  holder.icon.setVisibility(View.GONE);
 }
 holder.text.setText(item.getText());
 return view;
 }
 private class ViewHolder {
 ImageView icon;
 TextView text;
 }
} 

3、菜单项中item:  PopMenuMoreItem

/**
 * 菜单项.
 */
public class PopMenuMoreItem {
 public int id; //标识
 public int resId; //资源图标
 public String text;//文字
 public PopMenuMoreItem(int id, String text) {
 this.id = id;
 this.resId = 0;
 this.text = text;
 }
 public PopMenuMoreItem(int id, int resId, String text) {
 this.id = id;
 this.resId = resId;
 this.text = text;
 }
 public int getId() {
 return id;
 }
 public void setId(int id) {
 this.id = id;
 }
 public int getResId() {
 return resId;
 }
 public void setResId(int resId) {
 this.resId = resId;
 }
 public String getText() {
 return text;
 }
 public void setText(String text) {
 this.text = text;
 }
} 

4、宽度适配内容、不滚动的ListView：PopMenuMoreListView

/**
 * 宽度适配内容的ListView.
 * Author: msdx (645079761@qq.com)
 * Time: 14-9-2 下午5:14
 */
public class PopMenuMoreListView extends ListView {
 public PopMenuMoreListView(Context context) {
 super(context);
 }
 public PopMenuMoreListView(Context context, AttributeSet attrs) {
 super(context, attrs);
 }
 public PopMenuMoreListView(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 }
 @Override
 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
 int width = 0;
 for (int i = 0; i < getChildCount(); i++) {
  View child = getChildAt(i);
  child.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), heightMeasureSpec);
  int w = child.getMeasuredWidth();
  if (w > width) width = w;
 }
 widthMeasureSpec = MeasureSpec.makeMeasureSpec(width + getPaddingLeft() + getPaddingRight(), MeasureSpec.EXACTLY);
 super.onMeasure(widthMeasureSpec, heightMeasureSpec);
 }
} 

5、item的布局：item_popmenu_more.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:paddingBottom="10dip"
 android:paddingLeft="20dip"
 android:paddingRight="20dip"
 android:paddingTop="10dip">
 <ImageView
 android:id="@+id/menu_icon"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center_vertical"
 android:layout_marginLeft="5dip"
 android:layout_marginRight="5dip"
 android:src="@mipmap/demand_icon_location" />
 <TextView
 android:id="@+id/menu_text"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center_vertical"
 android:singleLine="true"
 android:textColor="#FFFFFF" />
</LinearLayout> 

6、更多菜单的布局：layout_popmenu_more.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:orientation="vertical"
 android:paddingRight="5dip">
 <ImageView
 android:id="@+id/corner_iv"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="right"
 android:layout_marginRight="15dip"
 android:contentDescription="@null" />
 <soban.orderscroll.PopMenuMoreListView
 android:id="@+id/menu_listview"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="right"
 android:cacheColorHint="@android:color/transparent"
 android:listSelector="@android:color/transparent"
 android:divider="#FFFFFF"
 android:dividerHeight="1px"
 android:focusable="true" />
</LinearLayout> 

7、例子Activity: MainActivity

public class MainActivity extends Activity {
 private static final int USER_SEARCH = 0;
 private static final int USER_ADD = 1;
 private PopMenuMore mMenu;
 private TextView mTextView;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 initMenu();
 mTextView = (TextView) findViewById(R.id.hello_tv);
 mTextView.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
  mMenu.showAsDropDown(mTextView);
  }
 });
 }
 private void initMenu() {
 mMenu = new PopMenuMore(this);
 // mMenu.setCorner(R.mipmap.demand_icon_location);
 // mMenu.setBackgroundColor(Color.parseColor("#ff8800"));
 ArrayList<PopMenuMoreItem> items = new ArrayList<>();
 items.add(new PopMenuMoreItem(USER_SEARCH, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, "添加"));
 items.add(new PopMenuMoreItem(USER_SEARCH, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, "添加"));
 items.add(new PopMenuMoreItem(USER_SEARCH, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, "添加"));
 /*items.add(new PopMenuMoreItem(USER_SEARCH, R.mipmap.demand_icon_number, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, R.mipmap.demand_icon_location, "添加"));
 items.add(new PopMenuMoreItem(USER_SEARCH, R.mipmap.demand_icon_number, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, R.mipmap.demand_icon_location, "添加"));
 items.add(new PopMenuMoreItem(USER_SEARCH, R.mipmap.demand_icon_number, "搜索"));
 items.add(new PopMenuMoreItem(USER_ADD, R.mipmap.demand_icon_location, "添加"));*/
 mMenu.addItems(items);
 mMenu.setOnItemSelectedListener(new PopMenuMore.OnItemSelectedListener() {
  @Override
  public void selected(View view, PopMenuMoreItem item, int position) {
  switch (item.id) {
   case USER_SEARCH:
//   startActivity(new Intent(this, UserSearchActivity.class));
   break;
   case USER_ADD:
//   startActivity(new Intent(getActivity(), UserAddActivity.class));
   break;
  }
  }
 });
 }
} 

8、例子布局：activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_main"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin">
 <TextView
 android:id="@+id/hello_tv"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="Hello World!" />
</RelativeLayout>
