在Android開發(fā)中，使用SmartRefreshLayout可以幫助我們輕松實(shí)現(xiàn)下拉刷新和上拉加載更多功能。為了使SmartRefreshLayout適配不同屏幕尺寸，我們需要考慮以下幾點(diǎn)：

  1. 在布局文件中聲明SmartRefreshLayout和RecyclerView：
<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical" />

<com.scwang.smartrefresh.layout.SmartRefreshLayout
    android:id="@+id/smartRefreshLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true">
</com.scwang.smartrefresh.layout.SmartRefreshLayout>
  1. 在Activity或Fragment中初始化SmartRefreshLayout和RecyclerView：
RecyclerView recyclerView = findViewById(R.id.recyclerView);
SmartRefreshLayout smartRefreshLayout = findViewById(R.id.smartRefreshLayout);
  1. 設(shè)置LayoutManager：
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
  1. 設(shè)置適配器：
MyAdapter adapter = new MyAdapter();
recyclerView.setAdapter(adapter);
  1. 設(shè)置SmartRefreshLayout的刷新和加載監(jiān)聽器：
smartRefreshLayout.setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh(RefreshLayout refreshLayout) {
        // 在這里執(zhí)行刷新操作
        refreshLayout.finishRefreshing();
    }
});

smartRefreshLayout.setOnLoadMoreListener(new OnLoadMoreListener() {
    @Override
    public void onLoadMore(RefreshLayout refreshLayout) {
        // 在這里執(zhí)行加載更多操作
        refreshLayout.finishLoadMore();
    }
});
  1. 為了使SmartRefreshLayout適配不同屏幕尺寸，我們需要在代碼中動態(tài)設(shè)置其高度?？梢允褂靡韵路椒ǐ@取屏幕尺寸：
public static int getScreenHeight(Context context) {
    WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    DisplayMetrics displayMetrics = new DisplayMetrics();
    windowManager.getDefaultDisplay().getMetrics(displayMetrics);
    return displayMetrics.heightPixels;
}

然后，在Activity或Fragment的onCreate方法中設(shè)置SmartRefreshLayout的高度：

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

    int screenHeight = getScreenHeight(this);
    ViewGroup.LayoutParams layoutParams = smartRefreshLayout.getLayoutParams();
    layoutParams.height = screenHeight - getSupportActionBar().getHeight() - (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48, getResources().getDisplayMetrics());
    smartRefreshLayout.setLayoutParams(layoutParams);
}

這樣，SmartRefreshLayout就能根據(jù)屏幕尺寸自動調(diào)整高度，從而實(shí)現(xiàn)不同屏幕尺寸的適配。
