我创建了DynamicTabbedLayout并在我使用的片段中添加了4个toogleButton,但是我遇到了无法使用onCheckedChanged()的问题,因为它在所有选项卡中都会更改。
我可以使用开关来检查选项卡,然后设置onCheckedChanged(),但是我有太多的选项卡。
是否有更好的方法可以将onCheckedChange()转到每个选项卡?
有我的代码:
MainActivity
public class MainActivity extends AppCompatActivity {
private ViewPager viewPager;
private TabLayout mTabLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_simulado);
initViews();
}
private void initViews(){
viewPager = findViewById(R.id.viewpager);
mTabLayout = findViewById(R.id.tabs);
viewPager.setOffscreenPageLimit(5);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(mTabLayout));
mTabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
setDynamicFragmentToTabLayout();
}
private void setDynamicFragmentToTabLayout() {
for (int i = 1; i <11 ; i++) {//listaQuestoes.size()+1
mTabLayout.addTab(mTabLayout.newTab().setText("test " + i));
}
SimuladoFragmentAdapter mDynamicFragmentAdapter = new SimuladoFragmentAdapter(getSupportFragmentManager(), mTabLayout.getTabCount());
viewPager.setAdapter(mDynamicFragmentAdapter);
viewPager.setCurrentItem(0);
}
