使用FragmentTabHost在选项卡片段之间传递参数

FragmentTabHost tabHost = findViewById(android.R.id.tabhost);
tabHost.setup(this, getSupportFragmentManager(), R.id.tab_content);

public class MyFragment extends Fragment {
    private String mParam;

    public static MyFragment newInstance(String param) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putString("param", param);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam = getArguments().getString("param");
        }
    }

    // 其他相关方法...
}

tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab 1"), MyFragment.class, null);
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab 2"), MyFragment.class, null);

tabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
    @Override
    public void onTabChanged(String tabId) {
        Fragment fragment = getSupportFragmentManager().findFragmentByTag(tabId);
        if (fragment != null && fragment instanceof MyFragment) {
            MyFragment myFragment = (MyFragment) fragment;
            Bundle args = new Bundle();
            args.putString("param", "参数值");
            myFragment.setArguments(args);
        }
    }
});
