本文實(shí)例為大家分享了ContextMenu長(zhǎng)按事件的實(shí)現(xiàn)具體代碼，供大家參考，具體內(nèi)容如下

/** *ContextMenu菜單就是長(zhǎng)按某一個(gè)組件，就會(huì)在屏幕的中間彈出ContextMenu，這里設(shè)置為長(zhǎng)按文本框彈出 *ContextMenu菜單 */public class MyContextMenu extends AppCompatActivity { /** *Called when the activity is first created. **/ final static int CONTEXT_MENU_1 = Menu.FIRST;//可以理解為ID設(shè)置的最小數(shù)值 final static int CONTEXT_MENU_2 = Menu.FIRST + 1; final static int CONTEXT_MENU_3 = Menu.FIRST + 2; TextView textView = null;//設(shè)置成員變量 @Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_my_context_menu);textView = (TextView)findViewById(R.id.label);//獲取textregisterForContextMenu(textView);//注冊(cè)長(zhǎng)摁菜單事件 } /** *創(chuàng)建菜單 **/ @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo){menu.setHeaderTitle('快捷菜單標(biāo)題');//設(shè)置標(biāo)題//設(shè)置對(duì)應(yīng)id及titlemenu.add(0, CONTEXT_MENU_1, 0,'菜單子項(xiàng)1');menu.add(0, CONTEXT_MENU_2, 1,'菜單子項(xiàng)2');menu.add(0, CONTEXT_MENU_3, 2,'菜單子項(xiàng)3'); } /** *設(shè)置對(duì)應(yīng)事件 **/ @Override public boolean onContextItemSelected(MenuItem item){switch(item.getItemId()){ case CONTEXT_MENU_1:Toast.makeText(MyContextMenu.this,'選中菜單子項(xiàng)1',Toast.LENGTH_SHORT).show();return true; case CONTEXT_MENU_2:Toast.makeText(MyContextMenu.this,'選中菜單子項(xiàng)2',Toast.LENGTH_SHORT).show();return true; case CONTEXT_MENU_3:Toast.makeText(MyContextMenu.this,'選中菜單子項(xiàng)3',Toast.LENGTH_SHORT).show();return true;}return false; } public void skip(View v){Intent intent = new Intent();intent.setClass(MyContextMenu.this,TabDemo.class);//從前者跳往后者startActivity(intent);//啟動(dòng) }}
