在android中创建自己的操作栏

我对android中的操作栏有一些问题。我想在左侧和右侧有一些图标。在左边我想有2个图标和文字，在右边我想有6个图标，但当文字很长的时候，我想在右边隐藏一些图标。在标准动作栏中，我只能从右向左添加项目，所以我决定创建自己的动作栏。我怎么开始？要做到这一点，我需要知道什么。你能给我一些建议或例子吗

这很简单。创建将从某些布局扩展的新类。膨胀xml，它将具有图标和按钮。并为逻辑显示\隐藏\设置侦听器等创建方法。我很早就做了，但现在我可以说这不是个好主意。创建应用程序必须遵循一些准则，这一点非常重要

我以前的项目中的示例：

public class ActionBar extends RelativeLayout {
    private ToggleButton buttonSave;
    private ToggleButton buttonClear;
    private ToggleButton buttonHelp;
    private ToggleButton buttonBack;
    private FrameLayout sepparator;
    private TextView textview;
    private ImageView imageViewIcon;


    public ActionBar(Context context, AttributeSet attrs) {
        super(context, attrs);

        LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        layoutInflater.inflate(R.layout.actionbar, this);

        initView();
    }

    private void initView () {
        buttonSave = (ToggleButton) findViewById(R.id.actionbar_togglebutton_save);
        buttonBack = (ToggleButton) findViewById(R.id.actionbar_togglebutton_back);
        buttonHelp = (ToggleButton) findViewById(R.id.actionbar_togglebutton_help);
        textview = (TextView) findViewById(R.id.actionbar_textview);
        imageViewIcon = (ImageView) findViewById(R.id.actionbar_imageview_icon);
        buttonClear = (ToggleButton) findViewById(R.id.actionbar_togglebutton_clear);
        sepparator = (FrameLayout) findViewById(R.id.actionbar_sepparator);
    }

    public void setOnSaveButtonClickListener (OnClickListener listener) {
        buttonSave.setOnClickListener(listener);
    }

    public void setSaveButtonDrawable (Drawable d) {
        buttonSave.setBackgroundDrawable(d);
        buttonSave.setVisibility(View.VISIBLE);
    }

    public void setOnHelpButtonClickListener (OnClickListener listener) {
        buttonHelp.setOnClickListener(listener);
    }
    public void setHelpButtonDrawable (Drawable d) {
        buttonHelp.setBackgroundDrawable(d);
        buttonHelp.setVisibility(View.VISIBLE);
    }

    public void setOnBackButtonClickListener (OnClickListener listener) {
        buttonBack.setOnClickListener(listener);
    }

    public void setBackButtonDrawable (Drawable d) {
        buttonBack.setBackgroundDrawable(d);
        buttonBack.setVisibility(View.VISIBLE);
    }

    public void setClearButtonDrawable (Drawable d) {
        buttonClear.setBackgroundDrawable(d);
        buttonClear.setVisibility(View.VISIBLE);
    }

    public void setOnClearButtonClickListener (OnClickListener listener) {
        buttonClear.setOnClickListener(listener);
    }

    public void setTitle (String value) {
        textview.setText(value);
    }

    public void setIcon (int resId) {
        imageViewIcon.setImageDrawable(getResources().getDrawable(resId));
    }

    public void setOnIconClickListener (OnClickListener listener) {
        imageViewIcon.setOnClickListener(listener);
    }

    public void setSaveButtonChecked (boolean value) {
        buttonSave.setChecked(value);
    }

    public void setSeporatorVisible (int visibility) {
        sepparator.setVisibility(visibility);
    }

    public void setOnIconListener (OnClickListener listener) {
        imageViewIcon.setOnClickListener(listener);
    }
}
