测试如何在博客中加入代码

public class FirstActivity extends BaseActivity {
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main1,menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.add_item:
                Toast.makeText(this, "You clicked Add", Toast.LENGTH_SHORT).show();
                break;
            case R.id.remove_item:
                Toast.makeText(this, "You clicked Remove", Toast.LENGTH_SHORT).show();
                break;
            default:
        }
        return true;
    }
