//记录Fragment的位置
    private int position = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_index);

        setTabSelection(position);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        position = savedInstanceState.getInt("position");
        setTabSelection(position);
        super.onRestoreInstanceState(savedInstanceState);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        //记录当前的position
        outState.putInt("position", position);
    }
