将 onclicklistener 添加到片段中的线性布局

Question

我有一个片段，用作我的活动之间的导航菜单。

每个图标都在一个单独的线性布局中，有自己的 ID。我正在尝试在每个线性布局的片段中实现一个 onclick 侦听器，以便在单击它时打开适当的 activity 并更改线性布局的背景以及 imageview 中的图像以表示点击。但是，当我单击线性布局时，什么也没有发生。我已经将 clickable 属性设置为 true，所以这不是问题所在。这是我的代码：

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_menu, container, false);
    }

// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
    LinearLayout betslayout = (LinearLayout) this.getView().findViewById(R.id.betnowlayout);
    betslayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            LinearLayout layout = (LinearLayout) v;
            layout.setBackgroundResource(R.drawable.selected);
            ImageView image = (ImageView) layout.findViewById(R.id.betnowimageview);
            image.setImageResource(R.drawable.footballsell);
            LinearLayout parent = (LinearLayout) v.getParent();
            LinearLayout mybetslayout = (LinearLayout) parent.findViewById(R.id.viewbetslayout);
            LinearLayout rankingslayout = (LinearLayout) parent.findViewById(R.id.rankingslayout);
            LinearLayout coinfrenzylayout = (LinearLayout) parent.findViewById(R.id.coinfrenzylayout);
            LinearLayout shoplayout = (LinearLayout) parent.findViewById(R.id.shoplayout);
            mybetslayout.setBackgroundResource(R.drawable.notselected);
            rankingslayout.setBackgroundResource(R.drawable.notselected);
            coinfrenzylayout.setBackgroundResource(R.drawable.notselected);
            shoplayout.setBackgroundResource(R.drawable.notselected);
            ImageView mybetsimage = (ImageView) mybetslayout.findViewById(R.id.betnowimageview);
            ImageView rankingsimage = (ImageView) rankingslayout.findViewById(R.id.rankingsimageview);
            ImageView coinfrenzyimage = (ImageView) coinfrenzylayout.findViewById(R.id.coinfrenzyimageview);
            ImageView shopimage = (ImageView) shoplayout.findViewById(R.id.shopimageview);
            mybetsimage.setImageResource(R.drawable.chipp);
            rankingsimage.setImageResource(R.drawable.medal);
            coinfrenzyimage.setImageResource(R.drawable.clover);
            shopimage.setImageResource(R.drawable.moneybag);
            Intent i = new Intent(getActivity(),AllGameslistActivity.class);
            startActivity(i);
            getActivity().finish();
        }
    });
}

Answer 1

首先，您应该创建自定义按钮。参见 this。并为图标 .

设置 onClickListener

Answer 2

问题出在这行代码

return inflater.inflate(R.layout.fragment_menu, container, false);

应该改为：return myfragment;

正确的做法是：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View myfragment = inflater.inflate(R.layout.fragment_menu, container, false);


    // TODO: Rename method, update argument and hook method into UI event

    LinearLayout betslayout = (LinearLayout) myfragment.findViewById(R.id.betnowlayout);
    betslayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("isitworkign", "yesyes");
            LinearLayout layout = (LinearLayout) v;
            layout.setBackgroundResource(R.drawable.selected);
            ImageView image = (ImageView) layout.findViewById(R.id.betnowimageview);
            image.setImageResource(R.drawable.footballsell);
            LinearLayout parent = (LinearLayout) v.getParent();
            LinearLayout mybetslayout = (LinearLayout) parent.findViewById(R.id.viewbetslayout);
            LinearLayout rankingslayout = (LinearLayout) parent.findViewById(R.id.rankingslayout);
            LinearLayout coinfrenzylayout = (LinearLayout) parent.findViewById(R.id.coinfrenzylayout);
            LinearLayout shoplayout = (LinearLayout) parent.findViewById(R.id.shoplayout);
            mybetslayout.setBackgroundResource(R.drawable.notselected);
            rankingslayout.setBackgroundResource(R.drawable.notselected);
            coinfrenzylayout.setBackgroundResource(R.drawable.notselected);
            shoplayout.setBackgroundResource(R.drawable.notselected);
            ImageView mybetsimage = (ImageView) parent.findViewById(R.id.viewbetsimageview);
            ImageView rankingsimage = (ImageView) parent.findViewById(R.id.rankingsimageview);
            ImageView coinfrenzyimage = (ImageView) parent.findViewById(R.id.coinfrenzyimageview);
            ImageView shopimage = (ImageView) parent.findViewById(R.id.shopimageview);
            mybetsimage.setImageResource(R.drawable.chipp);
            rankingsimage.setImageResource(R.drawable.medal);
            coinfrenzyimage.setImageResource(R.drawable.clover);
            shopimage.setImageResource(R.drawable.moneybag);
            Intent i = new Intent(getActivity(), AllGameslistActivity.class);
            startActivity(i);
            getActivity().finish();
        }
    });
    return myfragment;
}
