自定义Layout的基本框架

 

public class SimpleMenuView extends RelativeLayout implements OnClickListener {

	private Context mContext;

	public SimpleMenuView(Context context) {
		super(context);
		mContext = context;
	}

	public SimpleMenuView(Context context, AttributeSet attrs) {
		super(context, attrs);
		mContext = context;
	}

	public SimpleMenuView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		mContext = context;
	}

	public void init(final ItemAction action) {
		final Button btn01 = (Button) findViewById(R.id.btn_1);
		final Button btn02 = (Button) findViewById(R.id.btn_2);

		btn01.setOnClickListener(this);

		btn02.setOnClickListener(this);
	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch (v.getId()) {
		case R.id.btn_1:
			break;

		default:
			break;
		}
		
	}
}

 

//加载类方法

private void layoutInflater() {
		LayoutInflater mInflater = getLayoutInflater();
		if (simpleMenuView == null || simpleMenuView.getParent() == null) {
			final SimpleMenuView menuView = (SimpleMenuView) mInflater.inflate(R.layout.menu_view, null);
			simpleMenuView = menuView;
		}

		if (simpleMenuView.getParent() == null) {
			RL.addView(simpleMenuView);
		} 
		if (simpleMenuView != null) {
			ItemAction action = new ItemAction();
			action.text = "btn";
			action.action = new Action();
			simpleMenuView.init(action); // 初始化
		}
	}
	// ItemAction可以设置自定义Layout各种属性， action为其事件

	public static class ItemAction {
		public String text;
		public Action action;
	}

	public static class Action {
		public void run(Button btn) {
			
		}
	}
