而不是使用吐司，我想用在菜单项中的点击监听器，并且我们可以在这种情况下使用片段 这是我想添加点击，下面的代码，所以我可以打开一个新的活动

//启动菜单XML文件（menu.xml文件）

@Override 
    public boolean onCreateOptionsMenu(Menu menu) 
    { 
     MenuInflater menuInflater = getMenuInflater(); 
     menuInflater.inflate(R.layout.menu, menu);

Answer 1

是的，你可以做到这一点通过简单的开关壳体的内部添加一个Intent对每个菜单项。有供您参考在下面摘录一看：

@Override 
public boolean onOptionsItemSelected(MenuItem item) 
{ 

    switch (item.getItemId()) 
    { 
    case R.id.menu_bookmark: 

     // Ex: launching new activity/screen or show alert message 

     Intent intent = new Intent(yourActivity.this, NextActivity.class) 
     startActivity(intent); 
     return true; 

    default: 
     return super.onOptionsItemSelected(item); 
    } 
}  

Answer 2

@Override 
public boolean onOptionsItemSelected(MenuItem item) 
{ 

    switch (item.getItemId()) 
    { 
    case R.id.menu_bookmark: 

     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 

     return true; 

    case R.id.menu_save: 
     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 
     return true; 

    case R.id.menu_search: 
     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 
     return true; 

    case R.id.menu_share: 
     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 
     return true; 

    case R.id.menu_delete: 
     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 
     return true; 

    case R.id.menu_preferences: 
     Intent intent = new Intent(currentactivity.this, toactivity.class) 
     startActivity(intent); 
     return true; 

    default: 
     return super.onOptionsItemSelected(item); 
    } 
}  

意向 你必须使用意图从一个屏幕移动到另一个

Intent intent = new Intent(currentactivity.this,towhichactivityyouwantmove.class) 
    startActivity(intent);
