超级简单的底部导航按钮

用FragmentTabHost和LayoutInflater实现的底部导航按钮

先看一下布局文件
activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >


    <FrameLayout
        android:id="@+id/realtabcontent"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1" />

    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/maintab_toolbar_bg" >

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />
    </android.support.v4.app.FragmentTabHost>

</LinearLayout>

MainActivity

public class MainActivity extends FragmentActivity {
    // 定义FragmentTabHost对象
    private FragmentTabHost mTabHost;

    // 定义一个布局
    private LayoutInflater layoutInflater;

    // 定义数组来存放Fragment界面
    private Class fragmentArray[] = { FragmentPage1.class, FragmentPage2.class,
            FragmentPage3.class, FragmentPage4.class, FragmentPage5.class };

    // 定义数组来存放按钮图片
    private int mImageViewArray[] = { R.drawable.btn_common,
            R.drawable.btn_assets, R.drawable.btn_look,
            R.drawable.btn_position, R.drawable.btn_lable };

    // Tab选项卡的文字
    private String mTextviewArray[] = { "常用", "资产", "标签", "位置采集", "查看" };

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);//
        setContentView(R.layout.activity_main);

        initView();

    }

    /**
     * 初始化组件
     */
    private void initView() {
        // 实例化布局对象
        layoutInflater = LayoutInflater.from(this);

        // 实例化TabHost对象，得到TabHost
        mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
        mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

        // 得到fragment的个数
        int count = fragmentArray.length;

        for (int i = 0; i < count; i++) {
            // 为每一个Tab按钮设置图标、文字和内容
            TabSpec tabSpec = mTabHost.newTabSpec(mTextviewArray[i])
                    .setIndicator(getTabItemView(i));
            // 将Tab按钮添加进Tab选项卡中
            mTabHost.addTab(tabSpec, fragmentArray[i], null);
            // 设置Tab按钮的背景
            mTabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.tab_selector_background);
        }
    }

    /**
     * 给Tab按钮设置图标和文字
     */
    private View getTabItemView(int index) {
        View view = layoutInflater.inflate(R.layout.tab_item_view, null);

        ImageView imageView = (ImageView) view.findViewById(R.id.imageview);
        imageView.setImageResource(mImageViewArray[index]);

        TextView textView = (TextView) view.findViewById(R.id.textview);
        textView.setText(mTextviewArray[index]);

        return view;
    }

}

FragmentPage1
在这里复制5fragment就可以了

public class FragmentPage1 extends Fragment {

    View view;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        return view = inflater.inflate(R.layout.fragment_1, null);

    }
}

最后的效果
