Android将项目添加到全局上下文菜单

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.global_context_menu, menu);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    registerForContextMenu(findViewById(R.id.my_view));
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_settings:
            // 处理设置菜单项的点击事件
            return true;
        default:
            return super.onContextItemSelected(item);
    }
}
