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
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 ListmDataList = new ArrayList<>(); private ArrayAdapter mDataAdapter; private List 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(); } }
