第一步：写main xml文件
第二步：在mainactivity中设置图片和文字资源
// 图片 @DrawableRes private int mImages[] = { R.drawable.tab_counter, R.drawable.tab_assistant, R.drawable.tab_contest, R.drawable.tab_center }; // 标题 private String mFragmentTags[] = { "counter", "assistant", "contest", "center" }; private View getImageView(int index) { @SuppressLint("InflateParams") View view = getLayoutInflater().inflate(R.layout.view_tab_indicator, null); ImageView imageView = (ImageView) view.findViewById(R.id.tab_iv_image); imageView.setImageResource(mImages[index]); return view; } tab选中效果
第三步：MainActivity中实例化控件，这里使用了一个插件，叫做butterknife。极大省略了findviewbyid 这样的重复性代码。这样就可以使用mtabhost了
@Bind(android.R.id.tabhost) FragmentTabHost mTabHost; ButterKnife.bind(this)
第四步：写 oncreate方法
先设置fragment manager
然后给tab设置图片和文字，添加fragment
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); mTabHost.setup(this, getSupportFragmentManager(), android.R.id.tabcontent);//fragment管理 mTabHost.getTabWidget().setDividerDrawable(null); // 去掉分割线 for (int i = 0; i < mImages.length; i++) { // Tab按钮添加文字和图片 TabHost.TabSpec tabSpec = mTabHost.newTabSpec(mFragmentTags[i]).setIndicator(getImageView(i)); // 添加Fragment mTabHost.addTab(tabSpec, FragmentTab.class, null); // 设置Tab按钮的背景 mTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.color.pedo_actionbar_bkg); } }
第五步：写fragment
@Bind(R.id.tab_tv_text) TextView mTvText; private View mViewContent; // 缓存视图内容 @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { if (mViewContent == null) { mViewContent = inflater.inflate(R.layout.fragment_tab, container, false); } // 缓存View判断是否含有parent, 如果有需要从parent删除, 否则发生已有parent的错误. ViewGroup parent = (ViewGroup) mViewContent.getParent(); if (parent != null) { parent.removeView(mViewContent); } ButterKnife.bind(this, mViewContent); return mViewContent; } @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); // 显示Fragment的Tag信息 mTvText.setText(String.valueOf("Page: " + getTag())); } @Override public void onDestroyView() { super.onDestroyView(); ButterKnife.unbind(this); }
