对于列表来说，如果想操作某个列表项，一般会采用长按弹出菜单的形式，默认的上下文菜单比较难看，而QQ的上下文菜单就人性化多了，整个菜单给用户一种气泡弹出的感觉，而且会显示在手指按下的位置，而技术实现我之前是使用popupWindow和RecyclerView实现的，上面一个RecyclerView，下面一个小箭头ImageView，但后来发现没有必要，而且可定制化也不高，还是使用多个TextView更好一点。

我封装了一下，只需要一个PopupList.java文件。源码放在了git上，git地址：https://github.com/shangmingchao/PopupList

使用方式，很简单：

只需要一个PopupList.java文件和几行代码，你就可以为ListView，GridView，甚至任意View绑定一个长按弹出的水平气泡式菜单。
你可以这样使用：





public class MainActivity extends AppCompatActivity {



 



 



    private Button btn_long_click;



    private ListView lv_main;



    private List<String> mDataList = new ArrayList<>();



    private ArrayAdapter<String> mDataAdapter;



    private List<String> popupMenuItemList = new ArrayList<>();



 



 



    @Override




    protected void onCreate(Bundle savedInstanceState) {



        super.onCreate(savedInstanceState);



        setContentView(R.layout.activity_main);



        btn_long_click = (Button) findViewById(R.id.btn_long_click);



        lv_main = (ListView) findViewById(R.id.lv_main);



        mDataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_expandable_list_item_1, mDataList);



        lv_main.setAdapter(mDataAdapter);



 



 



        popupMenuItemList.add(getString(R.string.copy));



        popupMenuItemList.add(getString(R.string.delete));



        popupMenuItemList.add(getString(R.string.share));



        popupMenuItemList.add(getString(R.string.more));



        PopupList popupList = new PopupList(this);



        popupList.bind(lv_main, popupMenuItemList, new PopupList.PopupListListener() {



            @Override




            public boolean showPopupList(View adapterView, View contextView, int contextPosition) {



                return true;



            }



 



 



            @Override




            public void onPopupListClick(View contextView, int contextPosition, int position) {



                Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_SHORT).show();



            }



        });



 



 



        PopupList normalViewPopupList = new PopupList(this);



        normalViewPopupList.bind(btn_long_click, popupMenuItemList, new PopupList.PopupListListener() {



            @Override




            public boolean showPopupList(View adapterView, View contextView, int contextPosition) {



                return true;



            }



 



 



            @Override




            public void onPopupListClick(View contextView, int contextPosition, int position) {



                Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_SHORT).show();



            }



        });



 



 



        lv_main.setOnItemClickListener(new AdapterView.OnItemClickListener() {



            @Override




            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {



                Toast.makeText(MainActivity.this, "onItemClicked:" + position, Toast.LENGTH_SHORT).show();



            }



        });



        btn_long_click.setOnClickListener(new View.OnClickListener() {



            @Override




            public void onClick(View v) {



                startActivity(new Intent(MainActivity.this, SecondaryActivity.class));



            }



        });



        getData();



    }



 



 



    private void getData() {



        for (int i = 0; i < 40; i++) {



            mDataList.add("No." + i);



        }



        mDataAdapter.notifyDataSetChanged();



    }



 



 



}

注意：`bind()`方法要求你的anchorView不能有touch和longClick/itemLongClick监听，因为`bind()`方法会主动给anchorView设置监听器：




    mAnchorView.setOnTouchListener(new View.OnTouchListener() {



        @Override




        public boolean onTouch(View v, MotionEvent event) {



            mRawX = event.getRawX();



            mRawY = event.getRawY();



            return false;



        }



    });



    if (mAnchorView instanceof AbsListView) {



        ((AbsListView) mAnchorView).setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {



            @Override




            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {



                if (mPopupListListener != null




                        && !mPopupListListener.showPopupList(parent, view, position)) {



                    return false;



                }



                mAdapterView = parent;



                mContextView = view;



                mContextPosition = position;



                showPopupListWindow();



                return true;



            }



        });



    } else {



        mAnchorView.setOnLongClickListener(new View.OnLongClickListener() {



            @Override




            public boolean onLongClick(View v) {



                if (mPopupListListener != null




                        && !mPopupListListener.showPopupList(v, v, 0)) {



                    return false;



                }



                mContextView = v;



                mContextPosition = 0;



                showPopupListWindow();



                return true;



            }



        });



    }

这就限制了anchorView不能再添加touch监听，不能添加longClick监听，如果你需要添加监听可以使用`showPopupListWindow`方法主动来显示弹出框，而不是使用`bind()`方法：





public class SecondaryActivity extends AppCompatActivity {



 



 



    private ListView lv_main;



    private List<String> mDataList = new ArrayList<>();



    private ArrayAdapter<String> mDataAdapter;



    private List<String> popupMenuItemList = new ArrayList<>();



    private float mRawX;



    private float mRawY;



 



 



    @Override




    protected void onCreate(Bundle savedInstanceState) {



        super.onCreate(savedInstanceState);



        setContentView(R.layout.activity_secondary);



        lv_main = (ListView) findViewById(R.id.lv_main);



        mDataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_expandable_list_item_1, mDataList);



        lv_main.setAdapter(mDataAdapter);



 



 



        popupMenuItemList.add(getString(R.string.copy));



        popupMenuItemList.add(getString(R.string.delete));



        popupMenuItemList.add(getString(R.string.share));



        popupMenuItemList.add(getString(R.string.more));



 



 



        lv_main.setOnTouchListener(new View.OnTouchListener() {



            @Override




            public boolean onTouch(View v, MotionEvent event) {



                mRawX = event.getRawX();



                mRawY = event.getRawY();



                return false;



            }



        });



        lv_main.setOnItemClickListener(new AdapterView.OnItemClickListener() {



            @Override




            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {



                Toast.makeText(SecondaryActivity.this, "onItemClicked:" + position, Toast.LENGTH_SHORT).show();



            }



        });



        lv_main.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {



            @Override




            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {



                PopupList popupList = new PopupList(view.getContext());



                popupList.showPopupListWindow(view, position, mRawX, mRawY, popupMenuItemList, new PopupList.PopupListListener() {



                    @Override




                    public boolean showPopupList(View adapterView, View contextView, int contextPosition) {



                        return true;



                    }



 



 



                    @Override




                    public void onPopupListClick(View contextView, int contextPosition, int position) {



                        Toast.makeText(contextView.getContext(), contextPosition + "," + position, Toast.LENGTH_SHORT).show();



                    }



                });



                return true;



            }



        });



        getData();



    }



 



 



    private void getData() {



        for (int i = 0; i < 40; i++) {



            mDataList.add("No." + i);



        }



        mDataAdapter.notifyDataSetChanged();



    }



 



 



}

更详细的配置：

popupList.setIndicatorView(View)
popupList.setIndicatorSize(int, int)
popupList.setNormalBackgroundColor(int)
popupList.setPressedBackgroundColor(int)
popupList.setNormalTextColor(int)
popupList.setPressedTextColor(int)
popupList.setDividerColor(int)
popupList.setTextSize(float)
popupList.setTextPadding(int, int, int, int)
popupList.setTextPaddingLeft(int)
popupList.setTextPaddingTop(int)
popupList.setTextPaddingRight(int)
popupList.setTextPaddingBottom(int)
popupList.setBackgroundCornerRadius(int)
popupList.setDividerWidth(int)
popupList.setDividerHeight(int)
