我正在使用内部的 EditText 实现水平 RecyclerView。当我单击 EditText 或在 EditText 中输入文本时,RecyclerView 会自动滚动到开头。如何防止此滚动问题?
在这个我的应用程序中,您可以输入培训目标。
我在 EditText 上尝试过 setOnKeyStroke、onClick、setOnFocusChange。
我将 RecyclerView setFocusable 设置为 false。
我还尝试使用 RecyclerView 将 CoordinatorLayout 设置为 android:descendantFocusability="blocksDescendants" .
但这些都不起作用。
这是 main_layout.xml
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="0dp"
android:orientation="horizontal"
app:layout_constraintStart_toStartOf="parent"
android:id="@+id/goal_rv"
android:background="@drawable/recycler_view_background"
/>
</android.support.constraint.ConstraintLayout>
这是recycleView项目布局goal_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
>
<EditText
android:inputType="text"
android:id="@+id/generalEditText"
android:layout_width="300dp"
android:layout_height="63dp"
android:background="@drawable/edit_text_general_background"
android:foregroundGravity="fill_vertical"
android:gravity="center|center_vertical"
android:text="@string/add_goal"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="1.0"
/>
</android.support.constraint.ConstraintLayout>
这里是主要的:
goalRecyclerView = findViewById(R.id.goal_rv);
goalRecyclerView.setLayoutManager(new LinearLayoutManager(this, RecyclerView.HORIZONTAL, false));
goalRecyclerView.setFocusable(false);
goalRecyclerView.setOnClickListener(this);
generalAdapter = new GoalListViewAdapter(this);
generalAdapter.setOnItemClickListener(this);
goalRecyclerView.setAdapter(generalAdapter);
goalRecyclerView.setGoals(null);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);
这是适配器:
void setGoals(ArrayList<Goal> goals){
if(goals != null && this.goals != null && goals.size() != this.goals.size()) {
this.goals.clear();
this.goals = goals;
}
if(this.goals !=null) {
this.goals.add(EMPTY_GOAL);
this.goals.add(EMPTY_GOAL);/*problem appears in second edittext*/
}
}
ArrayList<Goal> getGoals(){
return goals;
}
@NonNull
@Override
public CustomViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.goal_layout, null);
viewHolder = new CustomViewHolder(view, listener);
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull CustomViewHolder customViewHolder, int i) {
Goal textAtPosition = goals.get(i);
customViewHolder.fillView(textAtPosition);
}
我希望在 EditText 中输入文本期间不会滚动 RecyclerView。在editText上聚焦和击键后,我滚动到开头。
最佳答案
我找到了解决方案:
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this, RecyclerView.HORIZONTAL, false) {
@Override
public boolean requestChildRectangleOnScreen(RecyclerView parent, View child, Rect rect, boolean immediate, boolean focusedChildVisible) {
if (((ViewGroup) child).getFocusedChild() instanceof EditText) {
return false;
}
return super.requestChildRectangleOnScreen(parent, child, rect, immediate, focusedChildVisible);
}
};
goalRecyclerView.setLayoutManager(linearLayoutManager);
