使用Android的多个列表视图滚动

我还没有这样做,但我一直在考虑,因为我可能需要这样做。我可以想到三个选项:对所有列表的内容只使用一个列表。您可以制作一个这样做的ListAdapter,并插入某种头。这可能是非常可重复使用的东西。

另一个想法是列出一份清单。但这听起来像是自找麻烦。

向前触摸事件 touched 查看其他视图。所有视图也将同步展开/折叠。

   OnTouchListener mOnTouch = new OnTouchListener()
    {
        @Override
        public boolean onTouch(View v, MotionEvent event)
        {            
            MotionEvent newEvent = MotionEvent.obtain(event);
            switch(event.getAction()){  
            case MotionEvent.ACTION_MOVE:
                if(mTouched == null){
                    mTouched = v;
                }
                mMovingFlag = true;
                break;
            case MotionEvent.ACTION_UP:
                if(mMovingFlag==false){
                    newEvent.setAction(MotionEvent.ACTION_CANCEL);
                }
                mMovingFlag = false;
                break;
            default:
                mMovingFlag = false;
                if(mTouched != null && mTouched.equals(v)){
                    mTouched = null;
                }
                break;

            }
            if(mTouched == null || mTouched.equals(v)){
                int items = mLayoutWithListViews.getChildCount();
                for(int list=0; list<items; list++){
                    AbsListView listView =mLayoutWithListViews.getChildAt(list));
                    if(listView != v){
                         listView.onTouchEvent(newEvent);
                    }
                }
            }
            return false;
        }
    };

除了两个网格视图和一个要滚动的列表视图外,我还有一个类似的问题。 我通过手动设置ListView和GridView的高度来解决:

    ListAdapter listAdapter = listView.getAdapter();

    int rows = listAdapter.getCount() / columns;
    int height = 60 * rows; // Insert the general cell height plus the dividers.

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = height;
    listView.setLayoutParams(params);
    listView.requestLayout();

希望我能帮助别人。

虽然这个答案是针对滚动视图而不是列表视图的,但问题是相同的,这个解决方案对我来说工作得很好。滚动左滚动视图将滚动右滚动视图和Viceversa。

 public class MainActivity extends Activity implements OnTouchListener {
    private ScrollView scrollViewLeft;
    private ScrollView scrollViewRight;
    private static String LOG_TAG = MainActivity.class.getName();
    private boolean requestedFocus = false;

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

        scrollViewLeft = (ScrollView) findViewById(R.id.scrollview_left);
        scrollViewRight = (ScrollView) findViewById(R.id.scrollview_right);

        scrollViewLeft.setOnTouchListener(this);
        scrollViewRight.setOnTouchListener(this);

        scrollViewLeft.setFocusableInTouchMode(true);
        scrollViewRight.setFocusableInTouchMode(true);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        Log.d(LOG_TAG, "--> View, event: " + view.getId() + ", " + motionEvent.getAction() + ", " + view.isFocused());
        Log.d(LOG_TAG, "--> " + scrollViewLeft.isFocused() + ", " + scrollViewRight.isFocused());

        if (motionEvent.getAction() == MotionEvent.ACTION_DOWN && requestedFocus == false){
            view.requestFocus();
            requestedFocus = true;
        }else if (motionEvent.getAction() == MotionEvent.ACTION_UP){
            requestedFocus = false;
        }

        if (view.getId() == R.id.scrollview_left && view.isFocused()){
            scrollViewRight.dispatchTouchEvent(motionEvent);
        }else if (view.getId() == R.id.scrollview_right && view.isFocused()){
            scrollViewLeft.dispatchTouchEvent(motionEvent);
        }

        return super.onTouchEvent(motionEvent);
    }
}

ListAdapter listAdapter = listView.getAdapter();
int rows = listAdapter.getCount() / columns;
 int height = 60 * rows; // Insert the general cell height plus the dividers.
 ViewGroup.LayoutParams params = listView.getLayoutParams();
 params.height = height;
 listView.setLayoutParams(params);
 listView.requestLayout();

使用可展开的列表视图。 我的答案是: Android ScrollView layout problem
