要在 RecyclerView 中去除分割线,有几种方法可以实现:
1. 使用默认分割线并将其设置为空:
```java
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL));
```
在这种情况下,您可以使用以下代码将默认分隔线设置为空:
```java
recyclerView.removeItemDecorationAt(0);
```
2. 自定义分割线:
如果您想要自定义分割线的样式或者需要更多的控制,您可以创建一个自定义的 ItemDecoration 类,并在 RecyclerView 上使用它。以下是一个示例:
```java
public class CustomDividerItemDecoration extends RecyclerView.ItemDecoration {
private Drawable divider;
public CustomDividerItemDecoration(Context context) {
divider = ContextCompat.getDrawable(context, R.drawable.custom_divider); // 自定义分割线的样式
}
@Override
public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
int left = parent.getPaddingLeft();
int right = parent.getWidth() - parent.getPaddingRight();
int childCount = parent.getChildCount();
for (int i = 0; i < childCount - 1; i++) {
View child = parent.getChildAt(i);
RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
int top = child.getBottom() + params.bottomMargin;
int bottom = top + divider.getIntrinsicHeight();
divider.setBounds(left, top, right, bottom);
divider.draw(c);
}
}
}
```
然后在您的 Activity 或 Fragment 中使用它:
```java
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.addItemDecoration(new CustomDividerItemDecoration(this));
```
无论您选择哪种方法,都可以将分割线从 RecyclerView 中移除。
