如何访问viewPager中的按钮

Question

我想问一下 ViewPager 我在 viewPager 中创建了 2 个布局，您可以在它们之间滑动。但我完全不知道如何访问这 2 个视图中的按钮。

    Button deleteButton;
TableLayout orderTable;
TableRow order;

TableLayout preparedTable;
TableRow prepared;
TextView plus;

JSONObject rows = new JSONObject( );
int last = 0;
private ViewPager tablePager;
private PagerAdapter pagerAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sliding_panel);
    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
    getSupportActionBar().hide();

    //orderTable.addView(order);

    List<Fragment> list = new ArrayList<>();
    list.add(new PageFragment1());
    list.add(new PageFragment2());
    tablePager = findViewById(R.id.main_view_pager);
    pagerAdapter = new SlidePageAdapter(getSupportFragmentManager(),list);

    tablePager.setAdapter(pagerAdapter);
    tablePager.setCurrentItem(0);
    setMain();

    /*LayoutInflater getView = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = getView.inflate(R.layout.main, null);
    plus = v.findViewById(R.id.plus);
    plus.setOnClickListener(this);*/
}

private void setMain() {
    View main = getLayoutInflater().inflate(R.layout.main, tablePager, false);

    orderTable = (TableLayout) main.findViewById(R.id.main_orders_table);
    order = (TableRow) main.findViewById(R.id.main_orders_rows);

    preparedTable = (TableLayout) main.findViewById(R.id.main_prepared_table);
    prepared = (TableRow) main.findViewById(R.id.main_prepared_rows);

    plus = (TextView) main.findViewById(R.id.plus);
    plus.setOnClickListener(this);

}
@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.plus:
            addOrder();
            break;
    }
}

那么我怎么能在其中一个视图中调用某些东西呢？这不会触发 onclicklistener。

请帮忙谢谢

您应该通过查找按钮 ID 从片段中访问按钮

Button mybtn=getActivity().findViewById(yourbtnid);
