自定义控件(瀑布流，LinearLayout)

通过转发触摸事件来单独对某个view进行控制处理。

<com.example.pinterestlistview.MyLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/mll"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/lv2"
        android:scrollbars="none"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <ListView
        android:id="@+id/lv1"
        android:scrollbars="none"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <ListView
        android:id="@+id/lv3"
        android:scrollbars="none"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

</com.example.pinterestlistview.MyLinearLayout>

dispatchTouchEvent  设置把触摸事件分发给那个view

package com.example.pinterestlistview;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;

public class MyLinearLayout extends LinearLayout {

	public MyLinearLayout(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	@Override
	public boolean onInterceptTouchEvent(MotionEvent ev) {
		return true;
	}

	@Override
	public boolean dispatchTouchEvent(MotionEvent ev) {
		return super.dispatchTouchEvent(ev);
	}

	@Override
	public boolean onTouchEvent(MotionEvent event) {

		//每个控件，也就是每个listView占据的大小
		int width=getWidth()/getChildCount();
		int height = getHeight();
		//获取布局里面有多少个控件  这里则是有多少个listView
		int count=getChildCount();
		//获取触摸时焦点的位置
		float eventX = event.getX();

		if (eventX<width){	// 滑动左边的 listView
			//不知道有什么用，但是一定得加，好像是没有鼠标位置是不可以的
			event.setLocation(width/2, event.getY());
			//把焦点事件分发给左边的listView
			getChildAt(0).dispatchTouchEvent(event);
			return true;

		} else if (eventX > width && eventX < 2 * width) { //滑动中间的 listView
			float eventY = event.getY();
			//焦点在上不部分  三个listView都滑动
			if (eventY < height / 2) {
				event.setLocation(width / 2, event.getY());
				for (int i = 0; i < count; i++) {
					View child = getChildAt(i);
					try {
						//三个listView都分发到焦点
						child.dispatchTouchEvent(event);
					} catch (Exception e) {
						e.printStackTrace();
					}

				}
				return true;
			} else if (eventY > height / 2) {
				event.setLocation(width / 2, event.getY());
				try {
					getChildAt(1).dispatchTouchEvent(event);
				} catch (Exception e) {
					e.printStackTrace();
				}
				return true;
			}
		}else if (eventX>2*width){
			event.setLocation(width/2, event.getY());
			getChildAt(2).dispatchTouchEvent(event);
			return true;
		}

		return true;
	}

}

MainActivity

package com.example.pinterestlistview;

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;

public class MainActivity extends Activity {

	private ListView lv1;
	private ListView lv2;
	private ListView lv3;

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

		lv1 = (ListView) findViewById(R.id.lv1);
		lv2 = (ListView) findViewById(R.id.lv2);
		lv3 = (ListView) findViewById(R.id.lv3);

		try {
			lv1.setAdapter(new MyAdapter1());
			lv2.setAdapter(new MyAdapter1());
			lv3.setAdapter(new MyAdapter1());
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	private int ids[] = new int[] { R.drawable.default1, R.drawable.girl1,
			R.drawable.girl2, R.drawable.girl3 };

	class MyAdapter1 extends BaseAdapter {

		@Override
		public int getCount() {
			return 3000;
		}

		@Override
		public Object getItem(int position) {
			return position;
		}

		@Override
		public long getItemId(int position) {
			return 0;
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {

			ImageView iv = (ImageView) View.inflate(getApplicationContext(),
					R.layout.lv_item, null);
			int resId = (int) (Math.random() * 4);
			iv.setImageResource(ids[resId]);
			return iv;
		}
	}
