使用Android中的Sherlock Library在ActionBar中添加菜单时出错？

Question

我正在使用Sherlock库的应用程序中使用示例代码。

我想在ActionBar的右上角添加菜单项，但在此过程中获得异常。 我使用下面的代码在Sherlock的 ActionBar中添加Menu 。

public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
        com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.layout.activity_main, menu);
        return super.onCreateOptionsMenu(menu);

    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        super.onOptionsItemSelected(item);

        switch (item.getItemId()) {
        case R.id.phone:
            Toast.makeText(getBaseContext(), "You selected Phone",
                    Toast.LENGTH_SHORT).show();
            break;

        case R.id.computer:
            Toast.makeText(getBaseContext(), "You selected Computer",
                    Toast.LENGTH_SHORT).show();
            break;

        case R.id.gamepad:
            Toast.makeText(getBaseContext(), "You selected Gamepad",
                    Toast.LENGTH_SHORT).show();
            break;

        case R.id.camera:
            Toast.makeText(getBaseContext(), "You selected Camera",
                    Toast.LENGTH_SHORT).show();
            break;

        case R.id.video:
            Toast.makeText(getBaseContext(), "You selected Video",
                    Toast.LENGTH_SHORT).show();
            break;

        case R.id.email:
            Toast.makeText(getBaseContext(), "You selected EMail",
                    Toast.LENGTH_SHORT).show();
            break;

        }
        return true;
    }

编译代码时获得以下异常：

Answer 1

您正在onCreateOptionsMenu()中展开布局（ R.layout.activity_main onCreateOptionsMenu()

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.layout.activity_main, menu);
    return super.onCreateOptionsMenu(menu);
}

将其更改为以下内容：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.some_menu_in_your_menu_folder, menu);
    return super.onCreateOptionsMenu(menu);
}

这是您将在res - > menu文件夹中创建的menu
