垂直滑动布局内的水平滚动
我有一个类似于导航抽屉的custom view类，但是它是从下到上打开的。
在我的XML中，此自定义类包装了一个水平的recyclerview。

所以我有一个水平滚动（回收视图），在垂直幻灯片内（自定义视图）。
问题是这样，请看下面的GIF文件：
如您所见，我无法在recyclerview中正确滚动。
您有什么建议吗？

答案 0 :(得分：2)
在onInterceptTouchEvent方法内的 SlidingLayer.java 类中，为MotionEvent.ACTION_MOVE操作添加以下代码：
if (xDiff > yDiff) {
return false;
}
它看起来像：
switch (action) {
case MotionEvent.ACTION_MOVE:
.
.
.
if (xDiff > yDiff) {
return false;
}
if (validHorizontalDrag || validVerticalDrag) {
mIsDragging = true;
setDrawingCacheEnabled(true);
}
break;
.

您可以执行以下操作：
1）MainActivity.class：
N2）activity_main.xml：
String#gsub3）horizontal_recycler_view_item.xml：
public class MainActivity extends AppCompatActivity {
private final String TAG = MainActivity.class.getSimpleName();
private RecyclerView mRecyclerView;
/*private float mDownMotionX = 0;
private float mDownMotionY = 0;
private final int SWIPE_SENSITIVITY = 100;
private final int SWIPE_X_SENSITIVITY = 10;
private final int SWIPE_Y_SENSITIVITY = 10;
private final int SWIPE_X_SENSITIVITY_MIN = 0;
private int SWIPE_X_SENSITIVITY_MAX = 0;
private final int SWIPE_Y_SENSITIVITY_MIN = 0;
private int SWIPE_Y_SENSITIVITY_MAX = 0;
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecyclerView = (RecyclerView) findViewById(R.id.mRecyclerView);
List<String> data = new ArrayList<>();
for (int i = 0; i < 100; i++) {
data.add("I " + (i + 1));
}
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
mRecyclerView.setLayoutManager(layoutManager);
HorizontalRecyclerViewAdapter horizontalRecyclerViewAdapter = new HorizontalRecyclerViewAdapter(MainActivity.this, data);
mRecyclerView.setAdapter(horizontalRecyclerViewAdapter);
mRecyclerView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent ev) {
mRecyclerView.getParent().requestDisallowInterceptTouchEvent(true);
/**
* You can adjust sensitivity by doing something similar to the code below
*/
/*final int action = ev.getAction();
switch (action & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_DOWN:
// Remember where the motion event started
mDownMotionX = ev.getX();
mDownMotionY = ev.getY();
break;
case MotionEvent.ACTION_MOVE:
// Scroll to follow the motion event
final float x = ev.getX();
final float y = ev.getY();
if (Math.abs(x - mDownMotionX) >= SWIPE_SENSITIVITY &&
mDownMotionX >= SWIPE_X_SENSITIVITY_MIN &&
mDownMotionX <= SWIPE_X_SENSITIVITY_MAX &&
Math.abs(y - mDownMotionY) <= SWIPE_Y_SENSITIVITY) {
mRecyclerView.getParent().requestDisallowInterceptTouchEvent(true);
} else{
mRecyclerView.getParent().requestDisallowInterceptTouchEvent(false);
}
break;
case MotionEvent.ACTION_UP:
break;
case MotionEvent.ACTION_CANCEL:
break;
}*/
return false;
}
});
final Display display = ((WindowManager) MainActivity.this.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
final Point deviceDisplay = new Point();
display.getSize(deviceDisplay);
/*
SWIPE_X_SENSITIVITY_MAX = deviceDisplay.x;
SWIPE_Y_SENSITIVITY_MAX = mRecyclerView.getHeight();
*/
}
public class HorizontalRecyclerViewAdapter extends RecyclerView.Adapter<HorizontalRecyclerViewAdapter.MyViewHolder> {
private final String TAG = HorizontalRecyclerViewAdapter.class.getSimpleName();
private final Context context;
private final List<String> data;
public HorizontalRecyclerViewAdapter(Context context, List<String> data) {
this.context = context;
this.data = data;
}
@Override
@NonNull
public HorizontalRecyclerViewAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.horizontal_recycler_view_item, parent, false);
return new HorizontalRecyclerViewAdapter.MyViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull HorizontalRecyclerViewAdapter.MyViewHolder holder, int position) {
holder.tv.setText(data.get(position));
}
@Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
final TextView tv;
private MyViewHolder(View itemView) {
super(itemView);
tv = (TextView) itemView.findViewById(R.id.tv);
}
}
}
}
