Tab栏和Fragment之间的切换

思路如下

  1. 先初始化星球、广场、聊天、我的四个界面的Fragment
  2. 点击星球的时候,更改星球的图片和文字颜色,其它的不变,并且显示星球所对应的Fragment,其余的Fragment隐藏.

既然有了思路,那么就直接干代码吧

//初始化Tab栏的文字
private void initEvent() {
   //给4个设置点击事件
   ll_star.setOnClickListener(this);
   ll_square.setOnClickListener(this);
   ll_chat.setOnClickListener(this);
   ll_me.setOnClickListener(this);

   //设置文字
   tv_star.setText(R.string.text_main_star);
   tv_square.setText(R.string.text_main_square);
   tv_chat.setText(R.string.text_main_chat);
   tv_me.setText(R.string.text_main_me);

   //一进去默认显示星球Fragment
   checkMainTab(0);
}

//初始化Fragment
 private void initFragment() {
     //星球
     if(mStarFragment == null){
              mStarFragment = new StarFragment();
              mStarTransaction = getSupportFragmentManager().beginTransaction();
              //将FragLayout替换为Fragment
              mStarTransaction.add(R.id.mMainLayout,mStarFragment);
		      mStarTransaction.commit();
}
     //广场
              if(mSquareFragment == null){
              mSquareFragment = new SquareFragment();
              mSquareTransaction = getSupportFragmentManager().beginTransaction();
              //将FragLayout替换为Fragment
              mSquareTransaction.add(R.id.mMainLayout,mSquareFragment);
              mSquareTransaction.commit();
      }
      //聊天
              if(mChatFragment == null){
              mChatFragment = new ChatFragment();
              mChatTransaction = getSupportFragmentManager().beginTransaction();
              //将FragLayout替换为Fragment
              mChatTransaction.add(R.id.mMainLayout,mChatFragment);
              mChatTransaction.commit();
      }
      //我的
              if(mMeFragment == null){
              mMeFragment = new MeFragment();
              mMeTransaction = getSupportFragmentManager().beginTransaction();
              //将FragLayout替换为Fragment
              mMeTransaction.add(R.id.mMainLayout,mMeFragment);
              mMeTransaction.commit();
      }
}


//写几个方法,方便我们操作Fragment
 //用来显示单个Fragment
        private  void showFragment(Fragment fragment){
                if(fragment !=null){
                        FragmentTransaction beginTransaction = getSupportFragmentManager().beginTransaction();
                        //在每次单个Fragment显示之前 隐藏所有的Fragment
                        hideAllFragment(beginTransaction);
                        beginTransaction.show(fragment);
                        beginTransaction.commit();
                }
        }

        //隐藏所有的Fragment
        private  void hideAllFragment( FragmentTransaction beginTransaction){
                //星球
                if(mStarFragment!=null){
                        beginTransaction.hide(mStarFragment);
                }
                //广场
                if(mSquareFragment!=null){
                        beginTransaction.hide(mSquareFragment);

                }
                //聊天
                if(mChatFragment!=null){
                        beginTransaction.hide(mChatFragment);
                }
                //我的

        }

现在我们的Tab栏切换Fragment已经完成。

3DTag的构建

现在我们来完成中间那个星球,中间的那个星球是GitHub上的一个第三方插件完成。
3DTag

代码如下

		mCloudView = view.findViewById(R.id.mCloudView);
        //初始化3D数据
        for (int i = 0; i < 100; i++) {
            mList.add("star"+i);
        }
        //创建3D星球的adapter
        CloudTagAdapter cloudTagAdapter = new CloudTagAdapter(mList, getActivity());
        //将adapter设置到view上面
        mCloudView.setAdapter(cloudTagAdapter);
        //监听事件
        mCloudView.setOnTagClickListener(new TagCloudView.OnTagClickListener() {
            @Override
            public void onItemClick(ViewGroup parent, View view, int position) {
                Toast.makeText(getActivity(), "position "+position, Toast.LENGTH_SHORT).show();
            }
        });
	
	//具体的显示在CloudTagAdapter 代码如下
public class CloudTagAdapter extends TagsAdapter {

    private List<String> mList;
    private  Context mContext;
    private LayoutInflater inflater;

    public CloudTagAdapter(List<String> mList, Context mContext) {
        this.mList = mList;
        this.mContext = mContext;
        this.inflater = (LayoutInflater) 
        mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return mList.size();
    }

    @Override
    public View getView(Context context, int position, ViewGroup parent) {
        View view = inflater.inflate(R.layout.layout_star_view_item,null);

        TextView textView = view.findViewById(R.id.tv_star_name);
        ImageView imageView = view.findViewById(R.id.iv_stat_img);
        textView.setText(mList.get(position));

        switch (position%10){
            case 0:
                imageView.setImageResource(R.drawable.img_star_icon_1);
                break;
            case 1:
                imageView.setImageResource(R.drawable.img_star_icon_2);
                break;
            case 2:
                imageView.setImageResource(R.drawable.img_star_icon_3);
                break;
            case 3:
                imageView.setImageResource(R.drawable.img_star_icon_4);
                break;
            default:
                imageView.setImageResource(R.drawable.img_star_icon_5);
                break;
        }
        return view;
    }

    @Override
    public Object getItem(int position) {
        return mList.get(position);
    }

    @Override
    public int getPopularity(int position) {
        return 7;
    }

    @Override
    public void onThemeColorChanged(View view, int themeColor) {

    }
}
