Android 从MenuItem获取Id并转到下一个活动

我已经用4个

菜单项创建了一个
菜单项
。我需要在按下
时检索
菜单项
Id，然后必须进行检查以查看按下了什么Id
并转到一个新的
活动
。我尝试过使用
item.getTitle（）
和
item.getItemId（）
但是它没有进入
if语句

popup_menu.xml
使用此
if（itemId==R.id.one）而不是
if（itemName==“工具7-力”| | itemId==“一”）

试试这个

    btnToolbox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            PopupMenu popup = new PopupMenu(Screen2_11.this, btnToolbox);
            popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());

            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {

                   int itemId = item.getItemId();

                    if (itemId == R.id.one) {
                        Intent i = new Intent(getApplicationContext(), Screen108_Force.class);
                        startActivity(i);
                    } else if (itemId == R.id.two) {
                        Intent i = new Intent(getApplicationContext(), Screen120_Focus.class);
                        startActivity(i);
                    } else if (itemId == R.id.three) {
                        Intent i = new Intent(getApplicationContext(), Screen119_Action.class);
                        startActivity(i);
                    } else if (itemId == R.id.four) {
                        Intent i = new Intent(getApplicationContext(), Screen136_Questions.class);
                        startActivity(i);
                    }
                    return true;
                }
            });
            popup.show();
        }
    });

您需要先初始化菜单。完成onCreate（）后添加此部分

然后在此处处理按下的项目选项

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    //here initialize your button pressed.

    return super.onOptionsItemSelected(item);
}
